We developed the educational purpose mobile application, named "Wild Flowers of Bukhansan National Park (version 1.0)", aiming for easy identification of wild flowers for students and visitors in the park. When visitors find a flower or part of plant in the park, visitors can search for its name utilizing the pictures and characters provided in their own smartphone mobile devices or tablet PCs. The application provides pictures of wild flowers in the park and character-based searching system based on 12 diagnostic features (e.g., growth form, leaf arrangement, flower symmetry, petal color, petal number, sepal number, etc). We adopted the complete floristic survey of Chung and Lee (1962) and added species that we confirmed their distribution in the park during the development of this application. In summary, number of vascular plants in this park was estimated to be 428 taxa including 100 families, 280 genera, 327 species, 1 subspecies, 50 varieties, and 5 formas. We provided a total of 588 pictures representing 358 taxa and each taxon includes multiple pictures in many cases. Included identification quizzes can be an efficient educational tool as well as fun activity for students and visitors who are learning plant species in Korea. Our next step will include GPS function in the application for indicating visitor's location and for providing previously reported sites of the species that we interested in the map of the park. The future application which includes GPS function will be a valuable tool for the monitoring of rare plants, plant researches related to the climate changes, etc. We currently provide Korean iPhone version only, and English version and both of android versions will be serviced soon.

조상과 후손의 만남에 대한 동서양 다원적 패러다임 연구 -주자의 감응이론과 칼융의 동시성이론을 중심으로-

박재갑 ( Jae-gahb Park ),고재석 ( Jae-suk Go ),전철 ( Chul Chun ) 충남대학교 유학연구소 2016 儒學硏究 Vol.34 No.-

우리 주위에서 인과관계를 알지 못하는 현상들을 드물지 않게 접한다. 이러한 현상들은 사실이 아니라고 보기보다는 어떠한 중요한 사실을 아직 알지 못하였기 때문에 이해가 안 되는 것이 아닌지 반문하게 한다. 이 글에서 근거로 삼은 자료는 논문의 공동필자인 박재갑 교수 집안에서 일어난 두 가지 사건이다. 첫째는 박재갑 교수의 15대 조상으로 1545년에 돌아가신 필재 박광우의 시신을 이장하는 날 밤, 사촌 형인 박재학의 꿈에 필재 할아버지가 나타나 자신이 소장하였던 방울을 찾아오라는 말을 듣고, 이후 파주에 가서 방울을 소장하고 있던 사람에게 방울을 찾아온 사건이다. 둘째는 박재갑 교수의 부친이 돌아가신 날 이모의 출가한 딸 꿈에 박재갑 교수의 부친이 금시계를 가지고 나타나신 꿈을 꾸었다. 이모의 딸은 이모부가 돌아가신 줄도 모르고 있었고 더욱이 이모부의 아들 부부가 금시계를 사갖고 온 것을 알 수가 없었는데, 금시계와 관련된 꿈을 꾼 일련의 사건이다. 과학을 주류 패러다임으로 삼고 있는 현대문명에서 보면, 신비롭고 기이한 현상은 그저우리가 확인하지 못하는 일상이나 정신현상의 일부일 수도 있다. 그런데 주자(朱熹,1130~1200)의 감응이론과 칼 구스타프 융(Carl Gustav Jung, 1875~1961)의 동시성이론은 인과관계를 알 수 없는 현상들에 대해 각기 다른 해석을 내놓는다. 인과관계를 알 수 없는 현상은 제한적 합리성의 완고한 세계관 자체가 균열되는 사건이며, 동시에 우리의 삶이 이해의 영역을 넘어선 광대한 현실에서 펼쳐지는 사건임을 말해준다. 실로 미지의 우주, 그리고 삶과 죽음에 대한 다원적 패러다임의 폭넓은 수용과 진지한 대화가 더 요청되는 시대이다. 이러한 관점에서 본 연구에서는 조상과 후손의 만남, 감응, 현현의 사례를 성리학의 감응이론과 칼 구스타프 융의 동시성이론의 관점에서 조명하고자 한다. We frequently witness phenomena which occur around us, not revealing the causal relationship. We can ask ourselves whether such phenomena are hard to understand not because they are not true facts but because they are beyond our understanding. The reference data for such a phenomenon in this article are the two events that had occurred in the family of Professor Jae-Gahb Park, one of the co-authors of this article. Firstly, on the eve of the night when his fifteenth-generation ancestor’s grave was to be moved, his ancestor appeared in his consin’s dream, telling him to go and find the bell that his ancestor had cherished. Accordingly, his father and relatives went to Paju county, where his ancestor’s grave is located, to remove the grave to another place. In the process, his father told the participants what his consin had dreamt of including a grave keeper who had kept the bell after reburial. The grave keeper returned it to his father after hearing from him. Secondly, On the day when Professor Park’s father died, his father appeared in the dream of his maternal aunt’s married daughter, carrying a gold watch with him. She was not aware that Professor Park’s father was dead. Furthermore, Neither did she know that Professor Park‘s old brother and his wife in America had bought the gold watch for his father. These two cases are representative examples of ancestors’ revelation through dream. According to the modern civilization which regards sciences as its mainstream paradigm, such mystical and arcane phenomena are just a part of mental phenomena that we cannot verify with our knowledge. However, there are two scholars presenting different explanations about the phenomena of which the causal relationship is not understood yet: Carl Gustav Jung (1875~1961)’s phenomenon of synchronicity and Zhu Xi (朱熹, 1130~1200)’s theory of correlation. A phenomenon whose causal relationship is not understood yet is an event in which the obstinate outlook of the restrictive rationality breaks off, and at the same time our life spreads into the vast realm transcending our understanding. We are living in an era when more discussions on the unknown universe and pluralistic paradigms on the questions about life and death need to be made. In this regard, Gustav Jung’s concept of Synchronicity and Neo-Confucian theory of correlation is instrumental in overcoming the phenomenon and case in which the causality breaks off.

This study was conducted to investigate physicochemical property changes from July 1998 to August 2001 in Mt. Bukhansan National Park. Four water sampling points were selected to measure the quality of stream water in the northeastern part of the Mt. Bukhansan National Park. The results were summarized as follows; In spring, the average pH of stream water was below the first class of the river water quality standard, while it was normal level in summer. The average electrical conductivity was about 2.3~3.3 times higher in downstream water than in upstream water during spring and summer. The contents of anions($Cl^-$, $NO{_3}^-$, $SO{_4}^{2-}$) were about 1.1~7.4 and 0.4~11.4 times higher in downstream than in upstream water, respectively. These results indicate that water quality was poorer in downstream than in upstream water. We suggest that stream water in the Mt. Bukhansan National Park should be protected from impacts of snow melting mineral particles in spring season and human impacts like wastewater of point source in summer season.

Background : To assess the current level of development of emergency medicine (EM) systems in Asia. Method : Survey of EM professionals from 12 Asian countries during a 90-day period from August to November 1998. 12 EM professionals from 12 Asian countries completed the survey. All participants were physicians. 7 participants (58%) gave presentations at an international EM conference during the study period. Respondents completed a 103 question questionnaire about the status of EM specialty, academic, patient care, information and management systems and the factors influencing the future of EM in their countries. Results : 92% of respondents stated that their countries have hospital-based emergency departments (ED). More than 80% of respondents reported that their countries have EMS systems and ED systems for trauma care and patient transfer. More than 70% stated that their countries have national EM organizations, EM research, national EMS activation phone numbers, ED systems for pediatric emergency care, emergency physician (EP) training in ACLS and ATLS and peer review. More than 60% reported official recognition of EM as an independent specialty status, ED triage systems and systems for customer service. More than 50% reported EM residency training programs, EM journals and EP ability to perform rapid sequence intubation (RSI). 50% reported EP ability to perform thrombolysis for acute MI and 33% reported EP ultrasonography. 92% felt that a lack of funding posed a moderate or great obstacle to the future development of EM in their countries. Conclusions : Many essential systems of EM now exist throughout Asia. In the systems of administration and emergency medical information in many countries, there are some parts to be developed further.

Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

쌀 생산비를 줄이고 대경지 규모화 영농에 적응할 수 있는 농기계 개발을 목적으로 연구개발한 대규모 경지적응 트랙터 부착 대형벼이앙기의 구성과 특징 및 개발시작기의 재배적 실용성 평가결과를 요약정리하면 다음과 같다. 1. 트랙터 부착 12조 대형벼이앙기는 크게 바퀴자국 제거로타리, 문짝형 정지판, 이앙장치부 등으로 구성되어 있다. 2. 트랙터 부착 12조 이앙기는 트랙터 동력을 이용하여 로타리, 정지 및 이앙작업이 동시에 이루어 질 수 있도록 개발하였다. 3. 바퀴자국을 없애는 날은 기존의 로타리 날을 교체하면 되도록 반달형 날로 제작하였다. 4. 이앙기는 이동시는 접을 수 있도록 설계 제작되어 대형화가 가능하므로 기존 6조 승용이앙기에 비하여 이앙작업 능력이 1.5배 이상이었다. 5. 트랙터 부착 대형벼이앙기는 트랙터와 같은 큰 동력원을 이용할 수 있으므로 측조시비기, 긴매트모 탑재 등 다양한 작업기 및 기능을 추가로 부착 가능하도록 설계되었다. 6. 트랙터 부착 대형벼이앙기는 어린모 및 중묘이앙시 결주율은 3.0∼4.3%로 기계이앙기 결주 허용범위 5% 미만이었다. 하지만 무경운 논에서는 이앙작업은 가능하나 부묘율이 다소 높은 점은 보완이 필요하다. To develop a labor saving rice cultivation technology, a new tractor attached rice transplanter has been developed for large scale farming and its field performance was evaluated. The rice transplanter consists of three major parts such as rotary for removing tractor tire furrow, door-shaped soil leveling plate and transplanting equipment. The rice transplanter is operated using the power of the tractor and performs rotary, harrow and seedling transplanting simultaneously. A half moon shaped rotary blade was found to be very efficient to remove tire furrow developed during seedling transplanting and the original rotary blade can be replaced easily with existed rotary blade. The seedling transplanting part of the transplanter was designed to fold into small size and the transplanting efficiency of the transplanter was found to be 1.5 times higher than that of the conventional riding type six row transplanter. Since the transplanter is operated through a strong power of the tractor, the additional attachment such as fertilizer application apparatus and long mat rice seedling carrier is possible. Based on the field performance of the transplanter, although the missing hill percentage showed roughly with 3.0∼4.3% for 10-day and 30-day old seedlings but the percentage is less than 5% which is maximum missing hill permit in the transplanting rice. Seedling transplanting in no-tillage field condition is acceptable but floating seedling percentage is still high and thus further technology improvement for minimizing floating seedling percontage is needed.
