According to the historical records, though the accurate origins were unknown, the history of Korean "Changs" may date back to about 1200 years ago. The age of early unified Shilla dynasty. The records reveal the first evidence of "Chang"―like soy products in this age. However, since it is generally believed that was imported from China about 2000 years ago, in the beginning of Sam-Kuk-age(三國時期初期) probably "Chang" manufacturing had started earlier. The records on Korean "Changs", however, are available not until the early stage of Yi dynasty. Undoubtedly during these long unrecorded period, the "Changs" manufacturing technology might had developed to certain degrees, since Koreans had been using continuously "Changs" as the basic cereal supplementing foods. But there is noway to know the history. In the records of the early Yi dynasty there appered, for the first time, the separate manufacturing and usage of Toenjang (fermented soybean mash) and Kanjang (soy sauce). Especially the Chinkanjang (陳甘醬―much concentrated or on aged soy sauce including Toenjang within) manufacturing was recorded already. These technology may be undoubtedly the result of long development during the unrecorded period. Later ku-Hwang-Chal-Yo (救荒撮要; a guide book for the relief of farmine) which was published in the age king Myung-Chong (明宗)recorded the various aspects of "Chang" manufacturing technology. According to this book, the "Chang" technology had especially progressed in the age of king Sae-Chong. (世宗). Koreans started to use wheat flour as the raw material of Toenjang meju (메주, soy sauce and soybean mash fermenting startar) in addition to soybean. A new device of expressing of soy sauce from soy sauce waste was also invented at that time. Therefor it can be said that the separate or independent manufacture of Kanjang and Toenjang was Completed in this age. According to the Sa-Si-Chan-Yo (四時纂要; a monthly farm guide) which was published in the year of king Hyo-Chong(孝宗) the "Changs" manufacturing had became one of the annual practices of Korean family and various kinds of characteristic "Changs" Kae-Chang (蟹醬), Jup-Chang (汁醬), Po-Chang (泡醬) were listed as the popular "Changs" at that times. Probably the fundamental technologies of many specific "Changs" manufacturing had been gradually established from the begining of the Yi dynasty to this age together with the development of food substitutes. A large modification in "Chang" manufacturing technology was brought in the middle ages of Yi dynasty. According to San-Lim-Kyung-Chai(山林經濟; a scientific encyclopedia) Chung-Chang (汁醬; the same as Kanjang) and Toenjang were described as the general purpose "Chang" of daily use and Jup-Chang (汁醬), Chung-Kuk-Chang (淸國醬) and Tam-Su-Chang (淡水醬) were listed as the popular specific "Changs" at that time. A new specific "Chang", Man-Cho-Chang (蠻椒醬, red pepper sauce) was deviced also in this age. Amang them the Chung-Chang is basically similar to the Present type of Korean Kanjang. It was described to be prepared entirely from soybean and Toenjang was the by-product of soy-souce, Undoubtedly the Present Korean Kanjang manufacturing technology may derive its origin to this Chung-Chang, using entirely soybean as the sole raw material. Probably further minor modifications, continued to improve "Chang" manufacturing technology and to adapt for home making method and scale, but essentially the similar "Chang" products which originated in the middle ages of Yi dynasty were conveyed to the present. Thus we can list the present day "Changs" as follows.; Chung-Chang, Toenjang, Nam-Cho-Chang (the same as Man-Cho-Chang) Jup-Chang, Chung-Kuk-Chang, Tam-Su-Chang. Among them the Chung-Chang and Nam-Cho-Chang are the only products of extensive general use by Korean of the Present day and others are only for occasional uses for an epicurism etc. The manufacturing procedures of present Korean Kanjang and Toenjang consist of three major steps; that is, the preparation of Meju, Kanjang fermentation, and expressing of sauce. The history of development of these three Kanjang manufacturing procedures are as the follows. I) The history of Kanjang-Meju Preparation method- The first record of Meju is found is San-Lim-Kyung-Jai. In this text it was described as: Cooked soy beans were mashed and made into small clumps and they were left in the room covered with brossonetia leaves, straw, grass leaves or morus bombysis leaves: Probably for microorganisms grow. From the middle ages Yi dynasty the Mejus were left piled in straw woven bages. The present day method, hanging the Mejus under the ceiling with straw ropes in the room, had been already described in the above San-Lim-Kyung-Jai also. It had been generally recogniged in the old texts of agriculture that coverage of Meju by yellow molds (黃衣) yielded good results. Without the present knowledge of pure culture technique of microbiology, it might hardly be expected to have a good growth of yellow molds by such primitive methods of Meju preparation, we can imagine. Probably such conditions rather might had favored the growth of bacteria and making Meju to Natto type soy product. We can think only of the effect of grass coverage on a good growth of yellow molds. There appeared many other very specific methods of Meju preparations described in the old texts, but none of them survived to be practiced and accepted among Koreans until to the present day. 2) The history of Kanjang fermentation- Until the middle age of Yi-dynasty Chin-Kanjang fermentation method which had been a device chiefly to obtain much concentrated soysauce so that it used small quantities of brine compared to the amount of Meju had been practiced. Later the tendency had come to obtain more quantities of dilute soy sauce and from the end of Yi dynasty the present day Chung-Chang fermentation method had emerged. This method has been using Meju: salt: water in the quantity ratio of 1 : 1 : 4. 3) History of method of expressing soy sauce- In the beginning the soy sauce had not been expressed from soybean mash but the whole mixtures had been consumed as "Chang". From the beginning of Yi dynasty as the need of soy sauce alone had become large the expressing method started to develope. In Ku-Hwang-Chal-Yo expressing by wood curtain was already described. In the middle ages of Yi dynasty, a hole was made in "Chang" and sauce exeeded in the hole was scooped out, or Yong-Su (a bamboo woven basket) were used to separate soy sauce from "Chang". From the end of Yi dynasty the present filtration method (for ex. using sive) were started to be used.

조직문화 변화 상황에서 구성원 태도와 행동 변화의 영향요인

현창혁(Hyun, Chang Hyuk),이호선(Lee, Hosun) 한국인사관리학회 2013 조직과 인사관리연구 Vol.37 No.2

본 연구에서는 조직문화 변화 상황에서 구성원의 태도와 행동 변화에 초점을 두었다. 즉 기업이 새로운 조직문화를 구축하기 위해 행동지침으로서의 공유가치를 조직 내에 정착시키는 데 있어서 구성원이 변화에 참여하고 지원하는 행동에 영향을 미치는 요인이 무엇인지를 구명하려 하였다. 구체적으로는 Herscovitch & Meyer(2002)의 변화몰입과 변화지지행동의 개념을 적용하여 구성원의 공유가치 실천 행동에 영향을 미치는 요인을 분석하였다. 그리고 변화몰입에 영향을 미치는 요인을 상사의 변혁적 리더십 요인과 구성원 자신이 지각하는 변화관련 인지적 요인으로 구분하고, 인지적 요인은 다시 변화관련 자기효능감, 변화결과 호의도, 조직의 변화준비성 등으로 세분화하여 영향의 정도를 파악하고자 하였다. 분석 결과, 변혁적 리더십과 지각된 변화관련 인지적 요인(변화관련 자기효능감, 변화결과 호의도, 조직의 변화준비성)이 모두 정서적 변화몰입과 공유가치실천 행동에 정의 영향을 미치는 것으로 드러났다. 아울러 정서적 변화몰입이 변혁적 리더십과 공유가치실천 행동 간의 관계를 매개하며, 변화관련 인지적 요인과 공유가치실천 행동 간의 관계에서도 매개효과가 있음이 밝혀졌다. This study is focused on attitudinal and behavioral changes of organizational members under context of organization cultural changes. That is, it tries to identify the factors that affect organizational members' behavior for participating and supporting in relation to organization changes when companies plan to settle down shared values as the code of conduct into the organizations so as to establish new organization culture. Data were collected from 748 full-time employees during Sep. and Oct. 2011, but 702 questionnaires were used to for analysis. Results indicate both transformational leadership and cognitive factors related to changes(change-related self-efficacy, positive expectancies to change outcome, and readiness for organizational change) have positive influence on organizational members' emotional commitment to organization change and behaviors of practicing shared values. Furthermore, organizational members' emotional commitment to organization change has mediating effect on the relationships between transformational leadership and their behaviors of practicing shared values. It also has mediating effect on the relationships between cognitive factors related to changes and organizational members' behaviors of practicing shared values. Finally, some implications of these findings are discussed and directions for future research are suggested.

柳昌鉉 최신의학사 1958 最新醫學 Vol.1 No.1

Series of studies regarding to the relation of the R.E.S. to allergic changes were carried out by many investigators. Boyd, Topley and Wilson, Wilson and Bloom, Hayashi and Maruyama described the produc- tion of antibody in the R.E.S.. Oka found that anaphyla ctic shock was inhibited by splenectomy. Prof.Yun, Far- mer reported that anaphylactic shock was inhibited by thymusectomy: Meanwhile, Ogawa and Isida recogni- zed that , anaphylactic shock was aggrevated by the administration of thymic substance. Juiigeblut and Berlot, Gay and Clark, Tuft, Oka, Sakurai, Watanave, Hirakawa and Ozima and Iwaii also recognized inhibition of anaphylactic shock in !he R.E.S. blockaded animals. Akahoshi, Apitz, Klinge and Umasugi reported that the main hyperallergic changes in liver were changed' in the stellet cells. Haedel and,Karsue have reported that anaphylactic- shock was inhibited by the-injection of a large dose of India ink solution and was aggrevated by a small dose of India ink solution: Prof. Yun, Moldovan, Slavoacet et Zolog found a protective substance against anaphylactic shock in the serum of the R. E. S. blockaded animal and claimed that the protective substance seems to be corresponded by the endocrine function in the R.E.S..Seul has reported that allergic in the liver were inhibited either by the injection of India ink solution or serum from the R. E. S. blockaded animal. 'Song also has recognized that the injection of India ink solution or serum from the R. E. S. blockaded animal inhibited allergic changes in the lungs. The experiment to be reported in this paper was to study the influence of the R.E.S. on allergic changes in thymus. Experimental material and method Normal rabbit weighing around 800 grams were used. I cc. of normal horse serum per kilogram of horse serum per kilogram of body weight given' locally . in thymus parencyma two weeks later.: For blockading the R.E.S., India ink solution obtained by the sterili- zation of i0% of BOPIL MUkJIP saline. solution was used. 1. Nonsensitizing group. The normal horse serum was injected locally in'the thymus parenchyma without sensitization. 2. Sensitizing group. The normal horse serum was injected subcutaneo 4 times for sensitizing. For reinjection, O.I cc, of normal horse serum per kilogram of body weight was given to the thymus parenchyma two weeks later. 3. Single injection of 50c. India ink solution. Allergic changes were observed in rabbits into which India ink solution, 5 cc. per kilogram of body Weight, was injected- intravenously 24 hours before sensitization. 4. Plural injection of 5 cc. India ink solution. Allergic changes were observed An rabbits into which India, ink :solution, 5 cc. per kilogram of body weight, was injected intravenouslly 6 times with 12 hours intervals 24 hours before sensitization. 5. Injection of the serum from normal rabbits. Allergic changes in. the thymus were observed in rabbits into which normal rabbit serum, 2 cc. per kilogram of body weight was injected intravenously 24 hours before sensitization. 6. Injection of the serum from single injection of 5 cc. India ink solution. Serum from rabbits, 2 cc. per kilogram of body weight,' into 'which 5 cc, of India ink solution per kilogram. of body weight had,,been injected was given 24 hours before sensitization. ` 7. Injection' of the serum from "plural injection of 5 cc. India ink solution. "The serum from rabbits, ,2 cc. per kilogram of body weight, into which 5, cc, of India ink solution per Kilogram of body weight " had been `injected 6 times with 12 hours intervals was given 24 hours before sensitization. Discussion Moldvan, Slovoaca of Zolog, Prof. Yun claimed the existance of inhibitory substance against allergic changes in the serum of the R.E,S. blockade. As ohs erved in these experiment, the 'injection of serum from rabbits blockaded with India ink solution, especially in the group receiving the serum from single iniection of India ink solution inhibited markedly allergic changes in thymus. It is quite apparent that the serum of the R. E. S. blockaded rabbits contain an inhibited subst- ante against allergic changes. Allergic changes in thymus were slightly inhibited. in rabbits directly blockaded with India ink solution. Jungeblut and Berlot, Gay and. Clark, Siegmond and Okazaki previously descrived the inhibition of allergic changes in the R.E.S. blockade. That is the inhibitory substance against allergic' changes were secreted from the R. E. S.. Conclusions. Studies on the relation between allergic changes in thymus and the R. E. S. are reported. 1) The injection of serum from the R.E.S. blockade with India ink solution inhibited allergic changes in thymus. 2) Direct blockade of the R. E. S. slightly, inhibited, allergic changes in thymus.

Impacts and Countermeasures of Climate Change on Food Supply

Climate change has become a megatrend that will lead to significant changes in future society. Korean and overseas agencies specializing in climate forecasts predict that average global temperatures will continue to rise. While climate change may potentially have certain positive impacts for crop yields, the overall impact is predicted to be negative for environment and food security. In this context, our study aims to suggest a plan for systematically establishing a stable food supply system in Korea in respose to climate change. Various analytical models were employed, including: a response analysis based on questionnaire for farmers, panel-based analysis of the causes of pests and diseases in rice production, a random-effects model for panel data of extreme weather impact, and an analysis of food supply effects using the Simulation Model for Climate-Agriculture Relations (SIMCAR) integrated model in conjunction with the Crop Estimation through Resource and Environment Synthesis (CERES) model of the Korea Agricultural Simulation Model (KASMO). An analysis was made of major grain yields by means of the KREI-KASMO. This revealed reduced yields and area in comparison with the baseline in 2050, resulting in a reduction of rice production by 17.8%p in the RCP8.5 scenario, and reduction of soybean by 21.2%p and reduction of barley by 13.7%p in the A2 scenario. Self-sufficiency ratio of major grains in 2050 drawn from the SIMCAR revealed that the climate change scenario for rice showed 55.0% to be reduced by 18.3% in comparison with the baseline. It is predicted that selfsufficiency ratio in rice will drop to 50% which means a half of consumed rice should be imported. Key tasks for building a stable food supply system to cope with climate change were developed based on the domestic production capacity, the buffering capacity to climate change, import capacity from other countries, and policy performance capacity with reference to the empirical analysis. First, the suggested key tasks for improving the domestic production capacity include developing and disseminating adaptation technology, conserving farmland and expanding arable land, practicing climate-smart agriculture by using fusion technology, and modernizing infrastructure for agriculture. Second, key tasks for improving buffering capacity to climate change are improving resilience and biodiversity, building a risk management system, and further improving storage of food in Korea and other countries. Third, major tasks for improving the import capacity from other countries are constructing overseas food bases, effectively using the international grain market, and enhancing international cooperation with relevant countries. Finally, key tasks for improving policy performance capacity are refining and applying the climate change impact analysis model with respect to policies, expanding investments in research and development, building a vulnerability assessment system, enhancing education and training, and installing Climate Change Response Center for Agriculture (tentative). In this study, several key challenges were presented in the four different areas related to building a stable food supply system which can help overcome the challenges of climate change. It is expected that the nature of the policies that need to be prioritized and promoted, given the constraints of budget, organization and information will be addressed in future research. Also, in order for the solutions for key challenges to work properly in the field such that policy outcomes will be maximized, a consortium of research bodies in the related fields of agriculture, agricultural meteorology and agricultural economics should be created. As preparation for specific action programs. Furthermore, follow-up studies should be conducted to verify the expenses required for developing reliable climate change impact assessment models and the effectiveness of the enforced policies.

Vegetation change and emerging research feedback for Korean National Long Term Ecological Research (KNLTER)

Cho, Yong-Chan,Lee, Chang-Seok,Cho, Hyun-Je,Lee, Kyu-Song,Park, Pil-Sun The Ecological Society of Korea 2011 Journal of Ecology and Environment Vol.34 No.1

Various responses of forest ecosystems to climate change underscore the need to improve our understanding of the environmentally-driven changes in forests, most effectively by long-term monitoring protocols. We have explored vegetation dynamics based on changes in community structure, species composition, diversity and demographics in four Korean National Long Term Ecological Research (KNLTER) sites--Mt. Nam, Mt. Jeombong, Mt. Worak, and Mt. Jiri--between 2004 and 2009. Most of the sites and forests studied exhibited increments in total basal area, but this was not observed in Quercus mongolica forests in Mt. Nam and Mt. Worak. Stem density exhibited various changes. Altitude gradient was the representative factor in differences in species composition. Two patterns of compositional change--convergence and divergence--were detected. The vegetation of Mt. Nam and Q. mongolica community of Mt. Work showed relatively larger changes in composition. However, in the other sites, few changes were observed. Changes of species richness were not notable except for Mt. Nam, where three species were added in the pine forest, whereas one species disappeared in the oak forest. In the oak forests, mortality rate was as follows (in descending order): Mt. Nam (25.5%), Mt. Jeombong (24.3%), Mt. Worak (16.4%) and Mt. Jiri (0.8%). In the pine forest, the recruitment rate was as follows (in descending order): Mt. Nam (63.7%), Mt. Worak (12.9%), Mt. Jeombong (7.6%) and Mt. Jiri (7.3%). The mortality rate and change rate of basal area were strongly negatively correlated (r = -0.9, P = 0.002), and the recruitment rate and change rate of density were positively correlated (r = 0.77, P = 0.026). In the KNLTER sites, larger vegetation changes were attributed to anthropogenic activities such as salvage logging. Suppression or competition for resources would also affect these changes. Research suggestions such as monitoring to clarify the causes of species mortality were discussed.

Changes of Landscape Structure for the Recent 20 Years in the Wangsuk Stream Basin of the Central Korea

Lee, Chang-Seok,Cho, Yong-Chan,Shin, Hyun-Chul,Lee, Seon-Mi The Ecological Society of Korea 2006 Journal of Ecology and Environment Vol.29 No.4

Landscape changes for 20 years between 1981 and 2001 in the Wangsuk stream basin located on the central Korea were investigated on the basis of physiognomic vegetation map made from the aerial photograph interpretation and field check. Changes of landscape structure were noticeable in agricultural field and forest landscape elements. Changes in the agricultural fields due to transformation of agricultural pattern into the institutional agriculture dominated landscape change, although urbanization also contributed to such change. The former change due to change of food production structure originated from socio-economic development during this period and the latter to the overpopulation of Seoul. As energy sources for heating and cooking, fertilizer, and fodder for livestock transform from plant materials to fossil fuel, manufactured one, and grain, succession of forest escaped from direct human disturbance dominated change of landscape structure in forested land. Differently from the positive landscape change in the upper area, change in the lower area deteriorated landscape quality by increasing artificial land. It was estimated that such landscape deterioration in the Wangsuk stream basin would influence water quality of the stream. In order to realize sustainable land-use against such environmental degradation, systematic environmental management based on landscape ecological perspective such as "an eco-plan for creating riparian vegetation belt," which is under preparation by Ministry of Environment, was recommended.

Objectives: The purpose of this study is to analyze the changes in the indices of body muscle strength, the indices of muscle strength associated with physical balance, and index of the pain relief between the intervention group who performed the muscle strength exercise and control group who not performed the muscle strength exercise. The study period was from September 7, 2016 to May 12, 2017, and it was conducted after receiving Institutional Review Board approval. Methods: Among 40 participants who were recruited in this study, the final analysis subjects were a total of 39 people, excluding the one people who dropped out during the 2-week. For analysis, the changes were compared with baseline and after two weeks by comparing three types of body muscle strength indices, four types of physical balance indices, and one type of pain relief index. Finally, we analyzed whether there is a difference between the groups in the each changes. Results: In the body muscle strength index change analysis, the change of muscle mass relative to weight was not statistically significant, but the difference between the groups regard to change was statistically significant (p<0.05). The lower body strength and the bone mineral were statistically significant in both the intervention and control group, but the difference between the groups regard to change was not statistically significant. In the index of muscle strength associated with physical balance change analysis, the intervention group showed improvement much higher in the right arm, left arm, right leg, and left leg of muscle mass than the control group. Also, the muscle mass of the right arm and the left arm was statistically significant in the analysis of the difference between the groups regard to change (p<0.05). Analysis of changes in pain relief index showed that the intervention group showed significantly improvement higher than the control group, and the difference between the groups regard to change was statistically significant (p<0.05). Conclusions: In the elderly patients in the hospital where the fall prevention program was provided, it was concluded that the intervention group higher improved the muscle strength associated with physical balance and the pain relief compared with the control group.

Brain Topological Correlates of Motor Performance Changes After Repetitive Transcranial Magnetic Stimulation

Park, Chang-hyun,Chang, Won Hyuk,Yoo, Woo-Kyoung,Shin, Yong-Il,Kim, Sung Tae,Kim, Yun-Hee Mary Ann Liebert 2014 Brain connectivity Vol.4 No.4

<P>Repetitive transcranial magnetic stimulation (rTMS) influences the brain temporally beyond the stimulation period and spatially beyond the stimulation site. Application of rTMS over the primary motor cortex (M1) has been shown to lead to plastic changes in interregional connectivity over the motor system as well as alterations in motor performance. With a sequential combination of rTMS over the M1 and functional magnetic resonance imaging (fMRI), we sought changes in the topology of brain networks and specifically the association of brain topological changes with motor performance changes. In a sham-controlled parallel group experimental design, real or sham rTMS was administered to each of the 15 healthy subjects without prior motor-related dysfunctions, over the right M1 at a high frequency of 10 Hz. Before and after the intervention, fMRI data were acquired during a sequential finger motor task using the left, nondominant hand. Changes in the topology of brain networks were assessed in terms of global and local efficiency, which measures the efficiency in transporting information at global and local scales, respectively, provided by graph-theoretical analysis. Greater motor performance changes toward improvements after real rTMS were shown in individuals who exhibited more increases in global efficiency and more decreases in local efficiency. The enhancement of motor performance after rTMS is supposed to be associated with brain topological changes, such that global information exchange is facilitated, while local information exchange is restricted.</P>

Long second toe: its nail and skin changes

( Geun-hwi Park ),( Woo-il Kim ),( Min-young Yang ),( Won-ku Lee ),( Tae-wook Kim ),( Sung-min Park ),( Hyun-joo Lee ),( Gun-wook Kim ),( Hoon-soo Kim ),( Hyun-chang Ko ),( Byung-soo Kim ),( Moon-bum 대한피부과학회 2018 대한피부과학회 학술발표대회집 Vol.70 No.2

Background: Nail can be affected by trauma, infection, and systematic disorders. In particular, the toe nails are exposed to the repeated and cumulative minor traumas, which usually result in thickened, splitted, and discolorated nails. Considering these, it can be inferred that the long second toe can be related to various nail and skin changes by repeated minor traumas such as friction in shoes, but the study or report on this topic hasn’t been done yet. Objectives: The purpose of this study was to introduce various nail and skin changes on long second toe. Methods: We analyzed the kinds of nail/skin changes of 50 patients with long second toe, enrolled at Pusan National University Hospitals (Busan and Yangsan) from 2013 to 2018. Results: There was no significant difference in the incidence of left and right toe and toenail, and 7 (14%) patients presented bilateral distribution. The most common nail change on long second toe was melanonychia (23, 46%), followed by subungual hematoma (15, 30%), onycholysis (2, 4%), subungual hyperkeratosis (2, 4%), onychomadesis (1, 2%), and retronychia (1, 2%). The most common skin change was corn (9, 18%), followed by paronychia (2, 4%). Twenty (20/50, 40%) patients also had other toe or toenail changes. Among them, the most common site was big toe/nail (13, 62%), and the most common change was subungual hematoma (8, 42%). Conclusion: Through this study, the dermatologists can recognize and diagnose the nail and skin changes of long second toe.
