기존 한옥의 계승을 위한 관련 연구가 진행되고 있으나, 한옥 보급에는 실용성을 띄지 못하고 있다. 이는 한옥 시공기술의 복잡성과 자재 생산기술 부족으로 인한 제한적 범위 내에서 공사가 진행됨에 따라 높은 공사비를 원인으로 꼽을 수 있다. 이에 따라 현재 전통 한옥이 가진 정체성을 살리고 현시대에 보급될 수 있는 신 한옥으로의 진화를 위해 부재간의 연관을 분석하고 조립하는 방식을 지식으로 구성하고 디지털 모델링을 함으로써 공사비 절감이 가능케 하는 방법 등이 연구되고 있다. 본 연구에서는 한옥 설계자를 고려한 효율적인 부재 가공 정보 지원을 목표로 한옥 부재 실무 가공 분석을 통해 경제성, 시공성을 파악하고 최적화 방안을 위한 한옥 부재 제작 CNC 시뮬레이션을 통해 효율적인 가공 프로세스의 발전 가능성을 예측하여 최적화된 부재가공 정보를 제안하고 이를 기반으로 한옥 수요자들을 위한 설계지원 방법에 대한 구체적인 방안을 제시함으로써 한옥의 생상성 향상에 기여하고자 한다. There have been a lot of studies about the Han-ok, the Korean-style house, in perspective of the inheritage of existing ones, but there are no practicality in the supply of Han-ok. The cause is considered to exist in the complexity of Han-ok and the techniques required to manufacture its components and in the relatively higher construction expenses in the process which is within restricted range. On the contrary, in order to preserve the identity of traditional Han-ok and encourage the evolution to create a new Han-ok that can be supplied to the present period, there has been studies that analyzes the connection between sub-components and assemble them into a digital model which can possibly decrease the expenses spent on construction. The research`s objective is to provide valuable information for Han-ok designers, which contains methods on manufacturing sub-components effectively. Furthermore, by analyzing the current manufacturing method`s workability and economic feasibility, the research can obtain an optimum alternative for improving Han-ok`s production. Also by using CNC simulation, the possibility of an effective production can be predicted, as well as the information that can lead to the optimum method for an efficient sub-component manufacturing and suggest a specific resolution which can also affect on the improvement of Han-ok productivity.

심리기술훈련이 리듬체조선수에게 미치는 효과에 대한 단일 사례 연구

한명우 ( Myung Woo Han ) 한국스포츠정책과학원(구 한국스포츠개발원) 2004 체육과학연구 Vol.15 No.4

최근 심리기술훈련의 효과를 살펴본 연구는 대부분 6개월 미만의 단기간 동안에 단일 피험자 사례 연구 설계를 사용하여 폐쇄기능 종목의 수행 향상을 보고하고 있다. 그러나 개방기능 스포츠 종목을 대상으로 심리기술훈련을 장기간 실시했을 때에도 효과가 있는지에 대해서는 아직 보고 된 바가 없다. 따라서 본 연구의 목적은 단일 피험자 사례 연구 설계를 활용하여 a) 심리기술훈련이 개방 기능 스포츠인 리듬체조에 효과가 있는지, 그리고 b) 장기간(6개월 이상)에도 효과가 있는지를 검증하는데 있다. 선수경력 10년인 21세(대학 2년생)의 리듬체조 대표선수를 대상으로 3년 동안 심리기술을 실시한 결과 대상자의 불안수준은 감소하고 자신감이 향상되었으며, 기분상태의 모든 하위영역이 긍정적으로 변하였다. 특히, 상태불안 및 우울 점수가 현저하게 낮아진 대신 활력점수가 현저하게 향상되었으며 결과적으로 경기력도 향상되었다. 또한, 대상자는 은퇴를 할 때까지 최선을 다하고 후회 없는 선수 생활을 하여 너무 기쁘고 보람되었다는 소감도 피력하였다. 이러한 결과는 개인의 요구에 맞게 작성된 심리기술훈련은 장기간동안에 실시되더라도 개방기술 종목에 효과적이라는 것을 명확히 보여주는 것이다. 이와 함께 심리기술훈련의 과정과 내용, 그리고 미래연구 방향이 제시되었다. Although previous studies have shown the effects of the PSTP on performance enhancement mainly in short-term period of the closed skills using single subject method, they haven`t examined the long term effects of the PSTP in the open skills. The purpose of this study was to investigate whether the effects of Han`s PSTP was effective for a college rhythmic calisthenics player(21 yrs.). Han`s PSTP was administered to the subject and her psychological profile was made after interviewing and examining the performance, traint-state anxiety, POMS, and concentration of the subject. A three-year PSTP was made bused upon her strong and weak points of the psychological profiles. Performance routine, self-talk, concentration, cognitive restructuring, thought stopping, imagination, and relaxation skills were educated and administered for her at least two sessions a week, 1-2 hours per a session. Once a year, all dependent variables were measured. All three-year data were compared to those of before treatment. After the treatment, trait and state anxiety were reduced to the similar level of the best performance. POMS were dramatically changed, especially on the depression and vigor domain. Her own feelings and emotions also showed dramatical changes in a positive direction. These results strongly indicated that the Han`s PSTP on an open-skill sports was effective even for a long-term period, which is a new finding to the field. The process and contents of the PSTP were introduced and future direction was discussed as well.

There have been a lot of studies about Han-Ok, the Korean-style house, in the perspective of existing Han-Ok’s inheritance, but there are no practicality in supply of Han-Ok. The cause is considered the complexity of Han-Ok construction techniques and higher construction expenses comparatively by processing in the restricted range by the shortage of the manufacturing technology of materials. On the contrary, for evolution to the new Han-Ok that can be supplied to the present period, there are studies that is analyzed the connection between sub materials and for possible modeling by formulating of assembling way. Thus, this study try to suggest the CNC process for new Han-Ok construction to secure construction relate to construction technique, which is determined by few expert technicians that is pointed out as problems of Han-Ok.

Results First, the number of stress related patients after IMF was more than before IMF(increased 31%), which suggests that IMF is the stressor of the people enough for psychiatric intervention. Second, IMF plays the role of the various stressors to Koreans (i.e, unemployment, retirement, economic loss, decreased incomes, familial conflicts, change of residence, urge to unemployed, etc) Third, IMF affects not only the urban clerical workers and merchants' employment and economic state but also the rural farmer and stock-farmers' economic state. Conclusion : IMF affects the Koreans' mental health in various aspects. So, it is important and urge to analyze and solve the IMF stresses which affect Koreans' mental health by psychosocial & community health approach.

인천국제공항철도와 기존 철도의 효율적인 연계방안

한우진(Han Woo-jin) 한국철도학회 2002 한국철도학회 학술발표대회논문집 Vol.- No.-

The Incheon International Airport Railroad (IIAR) is the railroad that connects Incheon International Airport, Gimpo Airport and Seoul Station. IIAR is now under construction, and it will be finished to Gimpo Airport by 2006, to Seoul Station by 2008. But IIAR is not only so late to start but also has no discussion about effective connecting methods to existing railroads and fine operation plan. Therefore, after IIAR opens, it is possible for IIAR to lose to limousine bus using highway. So, this paper proposes 4 effective connecting methods for IIAR - (1) Shuttle transport, (2) Short-distance connecting transport (Inside IIAR, Seoul Subway Line 9, "Han-River line") (3) Mid-distance connecting transport (Jung-ang, Tae-baek, Young-dong line) (4) Long-distance connecting transport (Korean Train eXpress (korean high speed railroad)) These methods can increase the connectivity of IIAR with existing railroads and the competition power of IIAR against highway.

This study investigates the influence of cane length on the weight distribution of the elderly in a standing position. Thirsty participants were evaluated using two different cane lengths based on measurements of distal wrist crease to ground (WC cane), and distance of greater trochanter to ground (GT cane). A limloader was used to determine the weight distribution on the subject. It was found that 6.5% of body weight was supported on a GT cane and 7.7% of body weight supported on a WC cane in a standing position. Results suggests that more weight is distributed on a WC cane than a GT cane in the elderly.

텔레비젼(TV)생산업체 근로자들의 영상단말기(VDT)작업이 시력과 안증상에 미치는 영향

우극현,최광서,정영연,한구웅,박정한,이종협,Woo, Kuck-Hyeun,Choi, Gwang-Seo,Jung, Young-Yeon,Han, Gu-Wung,Park, Jung-Han,Lee, Jong-Hyeob 대한예방의학회 1992 예방의학회지 Vol.25 No.3

영상단말기 (VDT)작업이 시력과 안증상에 미치는 영향을 알아보기 위해 1991년 7월에서 10월 사이에 구미시의 1개 TV생산업체에 종사하는 근로자들 가운데 채용 당시 안과적으로 문제가 없었고, 나안시력이 1.0 이상인 40세 미만 남자 338명을 대상으로 일일 평균 화면작업시간이 4시간 미만인 근로자(I군, 60명)와 4시간 이상인 근로자(II군, 204명)를 폭로군으로 하고 유사한 작업환경에서 근무하는 비화면작업자(74명)를 비폭로군으로 나누어 연령, 작업경력, 교대근무형태, 확대경 사용유무, 1일 평균 TV시청 시간 및 수면시간과 그리고 안자각증상에 대한 설문조사를 실시한 후, 안과적검사를 시행하였다. 조사시 원거리시력 (양안의 평균시력)이 채용시에 비해 0.15 이상 저하된 비율은 II군이 20.6%로 비화면작업군의 14.9 %, I군의 15.0 % 보다 다소 높았으나 통계적으로 유의한 차는 아니었다. 연령, 작업경력, 확대경 사용유무, 교대근무형태 등에 따라 층화하여 원거리시력 저하율을 비교해 본 결과 세 군간에 통계적으로 유의한 차가 없었다. 근거리시력 저하율도 비화면작업군이 28.4 %, I군이 18.3 %, II군이 27.5 %로 통계적으로 유의한 차이가 없었으며, 연령 등 4가지 독립변수를 층화하여 비교해 보아도 유의한 차이가 없었다. 안자각증상 호소율은 안피로를 포함한 7가지 항목에서 눈물이 나는 것을 제외한 모든 항목에서 비화면작업군에 비해 I군이, I군 보다는 II군이 통계적으로 유의하게 높았다(P<0.01). 화면작업자 264명 가운데 조명이 나쁜 장소에서 일하는 근로자들의 원거리시력 저하율과 안자각증상 호소율이 조명이 좋은 작업장에서 일하는 근로자보다 더 높았다(P<0.05). 7가지 안자각증상을 각 증상 마다 늘 느끼는 경우는 2, 가끔 느끼면 1, 느끼지 않으면 0으로 점수화하여 개인별 총 안증상 점수를 구해 세 군간에 원거리시력 차이 유무별로 비교해 본 결과, 시력차 유무에 따른 평균 안자각증상 점수의 차는 없었으나 시력차 유무에 관계없이 II군의 평균 안자각증상 점수가 6.13 으로 I군(3.53) 또는 비화면작업군(3.30) 보다 훨씬 더 높았다(P<0.01). 안자각증상 점수와 유의한 상관관계를 보인 독립변수들은 화면작업시간, 확대경 사용유무, 교대근무형태 등이었고, 채용시와 조사시 원거리시력 차이, 원거리시력과 근거리시력 차이, 누액분비기능, 안압, 굴절력 등과 유의한 상관관계를 보인 독립 변수는 하나도 없었다. 안자각증상 점수를 종속변수로 하는 중선형 회귀분석 결과에서는 화면작업시간이 길수록, 단부제나 2교대 근무자보다 3교대 근무자에서 유의한 선형관계를 나타내었다(P<0.01). 본 조사에서는 1일 장시간 VDT작업으로 시력이 저하되는 것은 관찰할 수 없었고 안자각증상은 유발되는 것으로 나타났다. 안자각증상의 예방을 위해 VDT 작업장의 조명을 적절하게 유지하고 장시간 연속해서 작업하지 않도록 작업관리를 해야 할 것이다. This study was conducted to evaluate the effect of VDT work on eyes and vision among workers in a TV manufacturing plant. The study subjects consisted of 264 screen workers and 74 non-screen workers who were less than 40 years old male and had no history of opthalmic diseases such as corneal opacities, trauma, keratitis, etc and whose visual acuity on pre-employment health examination by Han's test chart was 1.0 or above. The screen workers were divided into two groups by actual time for screen work in a day : Group I, 60 workers, lesser than 4 hours a day and group II, 204 workers, more than 4 hours a day. From July to October 1992 a questionnaire was administered to all the study subjects for the general charateristics and subjective eye symptoms after which the opthalmologic tests such as visual acuity, spherical equivalent, lacrimal function, ocular pressure, slit lamp test, fundoscopy were conducted by one opthalmologist. The proportion of workers whose present visual acuity was decreased more than 0.15 in comparison with that on the pre-employment health examination by Han's test chart was 20.6% in Group II. 15.0% in Group I and 14.9% in non-screen workers. However, the differences in proportion were not statistically significant. The proportion of workers with decreased visual acuity was not associated with the age, working duration, use of magnifying glass and type of shift work (independent variables) in all of the three groups. However, screen workers working under poor illumination had a higher proportion of persons with decreased visual acuity than those working under adequate illumination (P<0.05) . The proportion of workers whose near vision was decreased was 27.5% in Group II, 18.3% in Group I, and 28.4% in non-screen workers and these differences in proportion were not statistically significant. Changes of near vision were not associated with 4 independent variables in all of the three groups. Six out of seven subjective eye symptoms except tearing were more common in Group I than in non-screen workers and more common in Group II than in Group I (P<0.01). Mean of the total scores for seven subjective symptoms of each worker(2 points for always, 1 point for sometimes, 0 point for never) was not significantly different between workers with decreased visual acuity and workers with no vision change. However, mean of the total scores for Group II was higher than those for the Group I and non-screen workers (P<0.01). Total eye symptom scores were significantly correlated with the grade of screen work, use of magnifying glass, and type of shift work. There was no independent variable which was correlated with the difference in visual acuity between the pre-employment health examination and the present state, the difference between far and near visions, lacrimal function, ocular pressure, and spherical equivalent. Multiple linear regression analysis for the subjective eye symptom scores revealed a positive linear relationship with actual time for screen work and shift work(P<0.01). In this study it was not observed that the VDT work decreased visual acuity but it induces subjective eye symptoms such as eye fatigue, blurred vision, ocular discomfort, etc. Maintenance of adequate illumination in the work place and control of excessive VDT work are recommended to prevent such eye symptoms.
