  • The purpose of this study is to promote health for young female workers. It is based on questionnaires collected from 215 female workers in Incheon area. This study includes health condition (fatigue scores), occupational disease, knowledge of abused drugs and the actual condition of drug use. The results are summerized as follows: - $47.4\%$ visited their health center and were treated with diseases like cold and headache $(34.9\%)$, gastroenteric disease $(6.5\%)$, trauma $(7.9\%)$ and chronic disease such as diabetes and hypertension $(3.3\%)$ - $44.7\%$ received regular health education and $4.7\%$ among them received education on abused drugs. - $20.5\%$ were suffering from work related diseases such as gastroenteric disease, headache, trauma, repiratory disease, skin problem, arthritis, low back pain, shortsightness and tuberculosis. - Total mean fatigue score as an indication of health status was $9.0\pm5.4$ points out of 30 points. Physical mean score (group I) was $3.92\pm2.2$ points and psychological mean score was $2.5\pm2.3$ points and neurosensory mean score was $2.6\pm2.1$ points out of each 10 points. - They recognized analgesics $(55.0\%)$ and the next are laxatives $(49.8\%)$, inhalants $(40.0\%)$, narcotics $(24.2\%)$, stimulants $(24.0\%)$, antihistamines$(5.9\%)$, diuretics $(3.0\%)$, tranquilizer $(2.4\%)$ and sedatives $(1.4\%)$ - They used analgesics $(37.2\%)$ the most and then laxatives $(6.0\%)$, stimulants$(5.6\%)$, diuretics $(1.9\%)$, antihistamines$(0.5\%)$, And nobody used tranquilizer, sedatives, narcotics and inhalant. - The relationship between career, drug abuse education, health center utilization and and the actual condition of drug using was examined. The longer the career and the more educated with drug abuse, the less drug used. And those who utilized health center rarely used more drugs. - The relationship between career, health center utilization, the score of fatigue and use of analgesics was also examined. Those group who have a longer career above 3 years and the group who have never used health center used more analgesics. And the group of fatigue score above 11.0 points used a little more analgesics than the other group. These results indicate that analgesics are the most frequent used drugs among female workers. Those analgesics such as geborin, penzal, saridon, aspirin, tyrenol should be used properly. These basic data is submitted for the education and consultation which are carried out by industrial nurses for promoting health of industrial workers.

  • "Yixuerumen" is a comprehensive medical text published in the Ming-dynasty by Li Chan(李梴). In this text, Sanghan(傷寒, cold damage) is categorized among external contraction(外感) with much emphasis. The subject of this study is the verse "The Principal and secondary aspects must first be decided." and its annotations in the in the Sanghan chapter of "Yixuerumen". The complex theoretical structure of this verse was firstly analyzed, together with the historical background of how and why Li Chan adopted this concept. The Pyo-Bon concept is the contrast between phenomena(標) and its underlying source of motivation(本). The methodology for this study was to compare and analyze this main verse with contents on Sanghan and Un-gi(運氣) within the text, while reviewing historical theories explaining the physiology and pathology of the human body in terms of the Pyo-bon(標本) concept. As a result, we discovered that the Pyo-bon(標本) concept used in the aforementioned verse of "Yixuerumen" matches the Three Eum Three Yang(三陰三陽)-標本中氣(pyo-bon-jung gi)-gi transformation(氣化) theory of Un-gi(運氣). Li Chan created the connecting link in understanding the Three Eum Three Yang diagnosis system through the viscera/bowels theory(臟腑論) by adopting the Three Eum Three Yang(三陰三陽)-標本中氣(pyo-bon-jung gi)-gi transformation(氣化) theory from Un-gi. Li's work lead to several changes in the field of Sanghan. First, Li understood the disease pattern of Sanghan by using the accumulated knowledge of the viscera/bowel theory during the Jin-Yuan dynasty, and developed a medical perspective that observes the disease pattern based on the body's essence gi(精氣). Second, he set the category of the Sanghan-Three Eum Three Yang disease pattern, establishing a separate guideline. Third, by adding knowledge of herbs to the accumulated knowledge of the viscera/bowel theory, the process of diagnosis and herbal application were made explicable. On the other hand, in the process of interpreting the 三陰三陽 diagnosis system with viscera/bowels theory, theoretical inconsistencies appeared, of which Li tried to mend by several means. The results of the research on "Yixuerumen(醫學入門) the Sanghan chapter(傷寒篇)" calls for further studies, as it has effected both "Dongeuibogam(東醫寶鑑) the Sanghan part(寒門)" and "Dongeuisoosebowon(東醫壽世保元)" as well.

  • The accumulator is a passive safety injection device for emergency core cooling systems. As an important safety feature for providing a high-speed injection flow to the core by compressed nitrogen gas pressure during a loss-of-coolant accident (LOCA), the accumulator injects its precharged nitrogen into the system after its coolant has been emptied. Attention has been drawn to the possible negative effects caused by such a nitrogen injection in passive safety nuclear power plants. Although some experimental work on the nitrogen injection has been done, there have been no comparative tests in which the effects on the system responses and the core safety have been clearly assessed. In this study, a new thermal hydraulic integral test facility-the advanced core-cooling mechanism experiment (ACME)-was designed and constructed to support the CAP1400 safety review. The ACME test facility was used to study the nitrogen injection effects on the system responses to the small break loss-of-coolant accident LOCA (SBLOCA) transient. Two comparison test groups-a 2-inch cold leg break and a double-ended direct-vessel-injection (DEDVI) line break-were conducted. Each group consists of a nitrogen injection test and a nitrogen isolation comparison test with the same break conditions. To assess the nitrogen injection effects, the experimental data that are representative of the system responses and the core safety were compared and analyzed. The results of the comparison show that the effects of nitrogen injection on system responses and core safety are significantly different between the 2-inch and DEDVI breaks. The mechanisms of the different effects on the transient were also investigated. The amount of nitrogen injected, along with its heat absorption, was likewise evaluated in order to assess its effect on the system depressurization process. The results of the comparison and analyses in this study are important for recognizing and understanding the potential negative effects on the passive core cooling performance caused by nitrogen injection during the SBLOCA transient.

  • This study is largely aimed at presenting ways to improve the working clothes and help companies create more positive images by suggesting designs of the clothes, which take into accounts the corporate image, symbolism, function and aesthetic appreciation through introduction of companies' CIP. And, it is significant to propose working clothes development condition and process with introduction of companies' CIP(Corporate Identity Program : work that systematize and simplify visually images which companies or public bodies have) A way of this study was made up with working clothes design development process which a student planned. First of all, this study looked into Company D's Corporate Identity Program(CIP) to develop the design that corresponds with the characteristics of the company's favorite design, working environment and demands of the employees. And, then, the study conducted a survey of 30 employees and intensive interviews with heads of four teams including the Safety Team, the Working Clothes Management Team and the General Affairs Team to find out the requirements of the clothes and the characteristics of the company. Based on them, the concrete image that the company pursues and the direction of design were set up through image positioning. In the end, three different concept designs were presented through image-mapping and the concrete design of each item was developed. A total of seven items including upper and lower garments (a jacket and trousers) for the spring-summer seasons, upper and lower garments (a jumper and trousers) for the winter season, cold-protecting vest and winter clothes (a coat and trousers) were presented in accordance with the three concepts. One of the concept designs, which was selected through evaluation by employees of Company D, was produced as a sample and then the final design was chosen after a discussion attended by the head of each team and representatives of the employees. Based on the aforementioned design planning, one design was selected from each of the three concept designs for production. And each of these was requested to special production enterprise and manufactured. Following the result of study, by looking into a case of a practical joint design project between a university and a company, this study suggested ideas for business to improve working clothes through the academic-industrial cooperation and presented conditions and process of design development. And, this study also aims to examine the feasibility of academic-industrial cooperation based on the cases in which enterprises and universities staged joint projects to develop working clothes.

  • Background: Street vendors spend relatively more time near roadways and are vulnerable to air pollution related health disorders. However, there is limited information on the quality of the air they breathe. The objectives of this present study were to calculate the mass concentration of atmospheric particulate matter (PM) in eight size fractions ($PM_{0.4-0.7}$, $PM_{0.7-1.1}$, $PM_{1.1-2.1}$, $PM_{2.1-3.3}$, $PM_{3.3-4.7}$, $PM_{4.7-5.8}$, $PM_{5.8-9.0}$, and $PM_{9.0--0{\mu}m}$) at commercial (CML) and residential site (RSL) in Dehradun city from November 2015 to May 2016. To estimate the corresponding respiratory deposition dose (RDDs) in alveolar (AL), tracheobronchial (TB), and head airway (HD) region on street vendors working at CML and RSL. To find the association of atmospheric PM with RDDs and the incidence of respiratory related disorders among street vendors. Methods: Andersen cascade impactor was employed for calculating the PM mass concentration. Questionnaire based health survey among street vendors were carried out through personal interview. Results: A significant difference (p < 0.05; t-test) between the mean $PM_{0.4-10{\mu}m}$ mass concentration at CML and RSL was observed with ($mean{\pm}SD$) $84.05{\pm}14.5$ and $77.23{\pm}11.7{\mu}g\;m^{-3}$, respectively. RDDs in AL, TB and HD region at CML was observed to be 9.9, 7.8, and 7.3% higher than at RSL, respectively. Health survey revealed 1.62, 0.96, 0.04, and 0.57 times higher incidence of cold, cough, breathlessness, and chest pain, respectively with street vendors at CML compared to RSL. Conclusion: The site characteristics plays a major role in the respiratory health status of street vendors at Dehradun.

  • 본고에서는 여헌을 주인공으로 한 설화를 대상으로 하여 설화 전승의 주체인 민중들이 여헌을 어떻게 형상화하고 있는지를 살펴보았다. 현전하는 여헌 관련 설화는 무례한 관찰사 아들을 너그럽게 용서한<장현광의 소탈한 성품>, 의성 현령(縣令) 시 오월비상(五月飛霜)을 예견해 냉해를 막아낸 <여헌 선생의 예언>, 충북 보은의 '치마바위'와 청송 '여헌대'의 지명 유래 설화인 <치마바위>와 <여헌대> 4종밖에 되지 않는다. <장현광의 소탈한 성품>은 초라한 행색을 한 자신을 몰라보고 무례하게 군 젊은이를 너그럽게 용서하고 '검소함'과 '겸손'을 깨우쳐 주는 대학자의 소탈하고 너그러운 인품을 보여 준다. <여헌 선생의 예언>에는 백성들을 유교적 도덕으로 교화시키며, 백성들의 생업을 진작하기 위해서 힘쓰는 애민의식이 투철한 목민관의 모습이 그려져 있다. <치마바위>는 아내가 백성들로부터 전별 선물로 받은 비단 속곳마저 돌려주도록 한 청렴결백한 관리의 모습을 형상화하였으며, <여헌 선생의 예언>과 <여헌대>에는 앞날을 예견하는 비범한 도학자의 모습이 그려지고 있다. 이들 설화는 대체로 그의 성품이나 행적, 실제 사건 등을 토대로 하여 형성된 것으로 보이는데, 설화 속의 여헌의 형상은 '검소하고, 겸손하며, 도량이 넓고, 주역에 통달하였으며, 도덕적 경세관(經世觀)을 실천한' 그의 실제 모습에 근접해 있음을 알 수 있다.

  • 본 연구에서는 살균 및 비가열압착한 들깨오일(superilla)을 활용하여 영양성분을 확인하고 기능성 식품으로서의 가능성을 알아보기 위해 시판되는 들기름과 비교실험을 수행하였다. 수분 함량과 pH는 CPPO에서 높았고, 구리, 코발트, 칼슘 함량은 SRPO에서 높았다. 총 비타민 E, 토코페롤, 리놀렌산 함량은 LPPO에서 더 높았다. 총 폴리페놀 함량과 ABTS 라디칼 소거활성은 SRPO에서 가장 높은 수치를 보였으며, 아질산염 소거능 측정값은 CPPO에서 가장 높았다. L 및 a 값은 CPPO에서 더 높았고 b값은 LPPO에서 더 높았다. 이상의 결과를 통해 살균 및 비가열압착한 들깨오일(SRPO)의 무기질 함량, 총 폴리페놀 함량, ABTS 라디칼 소거활성 및 아질산 소거능이 있음을 확인하였다. 또한 시간이 경과할수록 SRPO는 과산화물가가 낮았고, LPPO는 산가가 유의하게 증가하였다. 따라서 본 연구를 종합해 볼 때, 살균 및 비가열압착한 들기름의 경우 기존의 방식으로 생산된 들기름과 영양소 성분이 유사하였다. 이는 새로운 들기름 제조방법을 제공하는 계기가 되었으며, 이를 통해 들기름의 상품화의 기초가 마련되었다고 판단된다.

  • 인간이 자연의 식물과 교감하는 화예는 역사적인 배경과 민족성에 따라 특징을 가지며 인간의 영감과 조형 능력으로 서로 다른 양상의 문화가 탄생 되었다. 한국의 화예는 사계절기후의 자연 속에서 발생한, 문명의 소산으로 자연합일사상(自然合一思想)에서 출발하여 우리민족의 심성에 흐르고 있는 자연주의적 본질의 삶과 철학을 시대의 문화에 맞게 자연식물(草木)로서 그 여유로운 미를 덕(德), 지(志), 기(氣)로 배양되어 빚어내었다. 문인화(文人花)는 역사적 전통인 동양철학의 바탕에 계승되어온 정신 이념이 고격의 인품과 시정성{詩情性)을 바탕으로 "외양(外樣)"보다는 식물이 지닌 특성과 취향을 기교의 표출됨이 없이 철리(哲理)의 미학적 함축성을 빚어낸 조형예술이다 본 연구에서는 우리 정신문화의 화예 근간이 문인화(文人花)임을 규명하기 위하여 소나무(松)를 중심으로 문인화의 배경과 근원, 시정성, 상징성, 우의성, 그리고 문인화 작품에서 표현되는 화예의 조형성과, 화예 유전자 해독으로 미학적 특성을 파악함과 동시에 문헌의 기록을 도출하여 연대별로 정리 고찰하고, 한국화예의 정수(精髓)인 문인화론을 정립하고자 한다.
