김진원(Jin-Won Kim),전자영(Ja-Young Jeon),박홍철(Hong-Chul Park) 국립공원연구원 2021 국립공원연구지 Vol.12 No.2

우리나라 구상나무 및 분비나무군락은 한라산을 제외하면 백두대간 마루금을 중심으로 국립공원 고지대에 대부분 분포하고 있으며, 구상나무는 지리산과 덕유산국립공원, 분비나무는 설악산국립공원에 비교적 넓은 면적이 분포한다. 따라서 두 수종에 대한 생육상태를 파악하고 모니터링하는 것은 국립공원 자연자원의 보전 측면에서 중요하다. 본 연구에서는 지리산, 덕유산, 설악산국립공원 내 서식 중인 구상나무와 분비나무군락에 대한 수년간의 고사실태를 파악하고자 하였으며, 이를 바탕으로 국립공원 아고산생태계의 과학적 보전 및 관리를 위한 토대를 마련하고자 하였다. 2009년부터 2020년까지 상록침엽수 고사현황을 조사한 결과, 지리산국립공원과 덕유산국립공원의 구상나무 고사 및 쇠퇴현상은 매년 나타나고 있으며, 2014년과 2015년에 상대적으로 높은 고사율을 나타냈다. 설악산국립공원의 분비나무 역시 편차는 있지만 구상나무와 마찬가지로 고사현상이 확인되고 있으며, 특히 관모능선과 설악폭포 지역의 고사현상이 지속되고 있다. 설악산 또한 2012년와 2014년에 상대적으로 사율이 높게 나타났지만 전반적으로 큰 차이는 없는 것으로 판단된다. 특정 연도에 고사율이 상대적으로 높게 나타난 요인으로는 태풍, 가뭄, 홍수, 강풍 등과 같은 기상이벤트에 의한 영향이 작용한 것으로 판단된다. 따라서 본 연구의 결과를 바탕으로 기상이벤트와의 관계성을 파악하는 후속연구가 필요한 것으로 판단되며, 이를 객관적으로 규명하기 위해서는 더욱 장기적인 모니터링 자료가 뒷받침되어야 한다. Excluding Hallasan National Park, Abies koreana and Abies nephrolepis communities are mostly distributed in the high elevation of the National Park on Baekdudaegan mountain. Abies koreana is distributed in Jirisan and Deogyusan National Park, and Abies nephrolepis is distributed in Seoraksan National Park. Therefore, grasping and monitoring the growth status of both species is important in terms of conservation of natural resources in Korea National Parks. In this study, we attempted to find out the mortality of Abies koreana and Abies nephrolepis inhabitant. The mortality and decay of Abies koreana in Jirisan National Park and Deogyusan National Park occur every year, with relatively high mortality rates in 2014 and 2015. Abies nephrolepis in Seoraksan National Park are also different, but the death phenomenon has been confirmed like Abies koreana. In particular, the death phenomena in the Gwanmo Ridge and Seorak Falls continue to occur. In addition, although the mortality rate was relatively high in 2012 and 2014, there is no significant difference overall. As a factor in which the mortality rate was relatively high in a specific year, it is assumed that the influence of meteorological events such as typhoons, droughts, floods, and strong winds. Therefore, based on the results of this study, it is recommended that a follow-up study is needed to grasp the relationship with the meteorological event, and longer-term monitoring data should be supported in order to objectively investigate this assumption.

본 연구는 도시지역에 침수피해가 발생하였을 경우, 장기적인 측면에서 침수피해를 최소화 할 수 있는 방안을 마련하기 위해 비구조적인 대책에 초점을 맞추어 도시공간적인 요인과 침수피해의 영향 관계를 분석하였다. 도시공간적인 요인에 의한 침수피해 영향을 분석하고자 다중회귀 분석(Multiple Regression Analysis)을 활용하여 적용하였다. 도시공간적인 요인은 Open Space, 방재시설, 도시화 부문으로 유형화하였다. 분석 결과, 침수피해 지역은 일정한 지역에 한정되어 발생하며, 공간적으로 매우 높은 상관성을 보이고 있음을 알 수 있다. Open Space의 면적이 넓을수록 침수피해액이 감소하는 바, 녹지, 공원 등의 감소가 침수피해를 증가시키고 있음을 확인할 수 있어, 도시의 안전이라는 기능적인 부분에 있어서 침수피해를 예방하고 대응하기 위해 매우 중요한 요인임을 알 수 있다. 도시화 부문에 포함되는 인구밀도, 지역내총생산(GRDP) 등의 요인은 그 값이 클수록 침수피해액은 증가하는 것으로 분석되어, 침수피해를 유발시키는 원인으로 판단된다. 따라서 기후변화에 적응하기 위해서는 녹지, 공원 등의 도시공간 계획을 전략적으로 수립해야 하며, 인구밀도, 지역내총생산(GRDP) 등은 침수피해를 유발시키는 주요 요인이므로 회복력 차원에서 적절하게 활용한다면 대응과 복구 역할을 할 것으로 판단된다. This study investigated the long-term measures to minimize flood damage in the event of flooding in urban areas. The relationship between urban spatial factors and the impact of flood damage was analyzed, focusing on non-structural measures. The urban spatial factors were categorized into three parts: open space, disaster prevention facilities, and urbanization sectors. Multiple regression analysis was used to investigate how urban spatial factors influence flood damage. As a result of the analysis, the crucial factors, such as the reduced green areas and parks included in the open space sectors, resulted in an increased flood damage potential. The posterior factors, such as the population density and GRDP included in the urbanization sector concurrently led to an increase in the flood damage potential. Therefore, to better adapt to climate change, it is necessary to establish urban spatial plans strategically, such as green areas and parks. Meanwhile, the population density and GRDP are also the main factors causing flood damage. Therefore, when used appropriately in terms of resilience, it will serve as adaptations and recovery.

Infectious diseases imported from other countries have increased as more and more Koreans are going abroad for various purposes. Tsutsugamushi disease from other endemic area such as Southeast Asia is important, because it can occur in any season and eschar may be absent. We report a case of imported tsutsugamushi disease acquired in the Philippines. A patient presented with fever, headache, and maculopapular skin rash. However, eschar was absent. Polymerase chain reaction (PCR) for 56-kDa gene of Orientia tsutsugamushi using buffy coat was positive. Serum indirect immunofluorescent antibody assay was initially negative but became positive with a titer of 1:320 at follow-up, Sequencing analysis revealed the strain to be 100% identical to the TW73R strain identified in Taiwan. After the patient received doxycycline, body temperature normalized in 12 hours. Tsutsugamushi disease is one of the differential diagnoses that should be included for patients with fever who have recently returned from Southeast Asian countries. PCR for O. tsutsugamushi using patient's buffy coat was useful for early diagnosis.

Because of the toxicity of hexavelant chromium ion, treatments of metallic surface with chromate compounds to retard corrosion are undesirable for safety control in industrial uses and protection of environment. In this study, we investigated several compounds such as inorganic. organic. and polymer materials in order to substitute the chromate conversion treatment on steel sheet. The corrosion property was investigated in a salt spray tester with 3.5 wt.% NaCl at 35℃. The results showed that the zirconium/silane/polymer triple coatings on the galvanized steel exhibited a significant retardation of corrosion. Although the multicoating system needs a cornplexed processing. we can confirm a possibility of development of a chromate-free chemical conversion treatment for galvanized steel sheet.

Efficiency of bus arbitration scheme is modeled to analyze and compare five known arbitration protocols for single-bus multiprocessor system. The analytical model describes average access time as a measure of efficiency and takes resubmitted requests into account, amending contradiction of previous assumption that bus requests in each cycle are independent of those of previous cycles. The analytical results obtained from our model show that the efficiency of the equal priority protocol is as good as that of the rotating priority protocol.

The elementary school curriculum has the trend now considerably emphasizing the affective characteristics of students. In this study, I try to verify how the thirty-day applicants of Constructivistic Problem Solving Strategy change the affective characteristics to math in the experimental class and show the differences between boys and girls in the experimental class. Therefore, to achieve the above aim, the following hypotheses have been put forward. The first, the Constructivistic Problem Solving Strategy would change the affective characteristics to math in the experimental class. The second, The effect of the Constructivistic Problem Solving Strategy changing the Affective Characteristics to Math would significantly differ between gender(boys and girls) in the experimental class. As the subjects for this study. 30 students from class one (the compared). 31 from class two (the experimented) in the 6th grade, Mokpo Yudal Elementary School, were selected and got a pre-test and a post-test. As the test instrument. I selected The Affective Characteristic Test for Study by Park, Byung-yang and others(1980) to extract 42 questions(i.e. the Self-Concept to Math in 14. The Studying Attitude og Math in 14, The Studying Habit of Math in 14). And The parts of the questions are amended according to this study aim and subject. The back & forth, left & right comparative test plan was used between two groups. For computer program SPSSWIN(Statistics Analysis System) has been used. Independent-Sample T-test was enforced to verify the difference of MEAN between two groups (the compared and the experimented) at hypothesis I. Paired-Sample T-Test was enforced to verify the difference of MEAN between boys and girls(the experimented) at hypothesis Ⅱ. The results of this study is as follows. The first, The experimented was improved the affective characteristics to math compared with the compared. Out of three affective characteristics within the study, the self-concept to math was not different the experimented from the compared for the back & forth comparison. The experimented significantly improved in the studying attitude of math and the studying habit of math for the back & forth comparison. The second, the both test(the pre-test and post-test) didn't demonstrate differences between boys and girls in the experimented concerning the affective characteristics to math. I reviewed the test results depending on three factors of the affective characteristics to math within the study. As for the self-concept to math, there weren't differences between both gender(boys and girls) of the experimented nor improvements. As for the studying attitude of math, both(boys and girls) showed improvements, especially boys. As for the studying habit of math. both showed improvements as the same rates. I conclude the followings based on the above result analysis of the study and hypothesis . The first, <hypothesis Ⅰ> is affirmative because the constructivistic problem solving strategy considerably increased more the affective characteristics to math of the experimented than that of the compared by statistics. <hypothesis Ⅰ-1> is negative because there were no differences between two groups, the experimented and the compared in regard to the self-concept to math. As for the studying attitude of math and the studying habit of math, the experimented was superior to its counterpart by statistics so that <hypothesis Ⅰ-2> and <hypothesis Ⅰ-3> are affirmative. Therefore we should expect the elementary school students to improve the affective characteristics to math by the constructivistic problem solving strategy. The second, <hypothesis Ⅱ> is negative because the affective characteristics to math didn't significantly differ between the boys and the girls in the experimental class, In addition. <hypothesis Ⅱ-1> is also negative because there weren't any differences between both regarding the self-concept to math. <hypothesis Ⅱ-2> is affirmative because the boys in the experimented were superior to the girls in regard to the studying attitude of math. <hypothesis Ⅱ-3> is negative because the results of the studying habit of math didn't show any differences between both gender of the experimented. Therefore. I argue that the application of the constructivistic problem solving strategy contributes to the improvement of the affective characteristics to math between elementary boys and girls not to sex standardization. Aad finally, as the affective characteristics to the elementary math is considered to be important. it's urgent to develop a variety of lesson strategy for cultivating the affective characteristics to math. I place an emphasis on the constructivistic method of education. And the efforts studying various constructivistic lesson method is required to draw up and operate the school and the school year curriculum by the seventh elementary school curriculum which will be adapted from the coming 2000 year.

한국 복싱의 退潮에 관한 小考

김원기,전만중,박상호 한국체육사학회 2003 체육사학회지 Vol.12 No.-

This paper started from a necessity to reconsider boxing sports, the only sports game that brought about our patriotism during the time when most of us were poor, and flied away out stress and anger, also, that made us dream and have a hope. The boxing game attracted people's interest at that time, meeting the spirit of hungry. However, boxing sports became an unpopular game nobody pays attention to. The reason was that all boxing games mobilized many boxing players and enthusiastic audience in the past, but as GNP elevated greatly, there are few hungry persons, the spirit of hungry was subdued, the number of players drastically decreased, demand of audience reduced, people don't enjoy watching boxing games, there are few spectators in boxing gyms, no sponsors support relay broadcasting for boxing games. Furthermore, results have been very poor in various amateur international boxing match, all broadcasting stations became to dislike relay broadcasting of international matches. A certain broadcasting station regularly sent out pro-boxing game programs every weekend for 45 years as it took a full charge of pro-boxing game, but frequency of relay broadcasting reduced now, and the reason that the popularity rating is lower than other popular sports games made the station avoid relay broadcasting, These results mean that reducing number of TV relay broadcasting showing the highest PR effect made boxing games inactive. Summing up the study, the reasons that boxing games have declined popular sports games' appearing, high-leveled foreign players' watching TV games, the law of diminishing marginal utility, and democratized society. As a result, demand of boxing games rapidly reduced. However, boxing games in Korea must remember Kim, Ki-su's acquisition of championship on July the 25th, 1966, WBA championships obtained by 16 players including Hong, Su-wan, Yu, Myung-woo, Park, Jong-pal, Mun, Seong-kil, and 11 WBC championships acquired by Yeon, Dong-kyun, Jang, Jeong-gu. They surely won an international fame flying the taegeuk flag all over the world. Also, in spite of short history of woman pro-boxing, Lee, In-young acquired a world championship, therefore, Korea still has a hope to meet another new jumping moment.

대형 프로젝트 수주를 위해서는 기획·관리능력뿐만 아니라 건설업체의 금융조달능력이 필요하다. 프로젝트 파이낸싱은 단일금융기법이 아닌 복합적이고, 다양한 이해당사자가 관련된 자금조달기법이므로 그 관계당사자중 한 부분의 노력만으로는 성공할 수는 없다. 정부와 금융기관이 협조를 강화하고, 특히 정부차원에서 지원정책과 규제 완화조치로 지원을 개선하는 노력이 필요하다. 이에 국내 건설업체도 프로젝트 파이낸싱의 도입을 건설 수주를 위한 하나의 수단으로만 받아들이는 오류를 피하고 국내외 건설환경을 분석·대응하는 등의 적절한 대처가 요구되며, 기술경쟁력뿐만 아니라 건설관리능력과 자금조달에 관련하여 프로젝트 파이낸싱의 필요성을 인식하고 연구하여 활용하도록 해야 한다. Receiving a major project order requires not only planning and management but financing capability of construction companies. Since project finance is multi-complex financial supply method by various parties concerned not a single supply method, it can not succeed with one part's effort. It is also necessary to reinforce the relationship between the governments and financing companies, especially the support and regulation relax policy by the governments. As such, domestic construction companies should not consider induction of project finance as a means of acceptance a construction environment in domestic and overseas. And also it is necessary to apply in the field which researched about technology competitiveness, construction management capability and financial supply.
