  • The purpose of this paper is to develop the Index of Balanced Life from the Korean life style. This paper presents How Koreans live for 24 hours a day, generally. The Index of Life Style is composed of necessary life, duty life and leisure life. Specifically, this paper considers moving time of activity between indexes of balanced life. We suggest that there is a difference among the characteristics, i.e., a sex, week, state of student and region that are explained by analyzing the exploratory data. Thereafter we obtain the statistical inference from each characteristic table.

  • 톱다리개미허리노린재는 콩과작물과 과수에 경제적 피해를 주는 주요해충이다. 본 연구는 톱다리개미허리노린재의 온도에 따른 산란특성을 규명하고 수정란을 이용한 산란모형과 생명표 매개변수를 추정하기 위하여 15.8, 19.7, 24.0, 27.8, 32.6, 34.0, $35.5^{\circ}C$ 정온조건에서 실험을 실시하였다. $15.8^{\circ}C$를 제외하고 조사된 모든 항온온도조건에서 산란이 가능하였다. 암컷 성충 수명은 $15.8^{\circ}C$ (110.5일)에서 가장 길었으며 온도가 올라갈수록 짧아지는 경향을 보였다($19.7^{\circ}C$에서 76.6일, $35.5^{\circ}C$에서 20.6일). 전체 산란수와 수정란수는 $24.0^{\circ}C$ (193.5와 151.2)에서 가장 많았으며 부화율은 $27.8^{\circ}C$ (84.0%)에서 가장 높았다. 전체 산란수와 수정란수를 이용하여 산란모형과 생명표 매개변수를 비교하였다. 수정란수를 이용시 온도별 총산란수 모형의 추정된 총산란수(159개)는 전체 산란수(190개)를 이용했을 때보다 적었다. 생명표분석에서 수정란을 이용하였을 때 개체군순증가율과 평균세대기간은 전체 산란수를 이용한 결과보다 작은 값을 나타내었다. 수정란을 이용한 산란모형 작성과 생명표분석은 실질적인 개체군변이를 이해하는데 도움이 될 것이다.

  • This study aims to suggest a rural village development policy considering tourists' stay pattern and villages' resources which can be infrastructure for green-tourism. For this purpose, a relationship table between amenity resources and the stay pattern was developed as a guide line to combine a set of several facilities fer village renewal. The amenity resources system was classified into three sub-classes(social, industrial, and natural/cultural/historical resources) and a relationship diagram between three classes and tourists' behavior was also defined. The table and diagram were applied to make renewal plan for 40 rural villages of the study area, Bukmyun, Cheonan, Chungnam province, so that the development scheme for the villages was suggested reasonably by the new findings of this study.

  • Today, due to the development of the industrial society, the need for sustainable research and development for energy depletion and environmental protection is increasing. Among sustainable research, remanufacturing is an ideal way to meet environmental and economic aspects. In this paper, we investigated the End-of-Life Vehicle(ELV) in order to find the recovery method of the core which is the preceding stage of remanufacturing. The number of End-of-Life Vehicle is increasing year by year, but the core recovery rate from ELV is still low. Therefore, a methodology to determine the disassembly priority of each part is proposed to increase the core recovery rate. Based on the analysis Table through the disassembly process, the decision rule was selected and the weighted score evaluation Table was completed to complete the disassembly priority system. Finally, evaluation was made on gasoline vehicles to determine priorities.

The seasonings are soybean sauce, Jinjang, red peper bean paste, Zupjang, Dampukjang, Chunggukjang, honey, vinegar, mustard, Yunzup etc. Storage foods are vegetables,fruits and beans etc. There are 62 kinds of table ware and cooking kitchen utensiles, but many of them came to usefulness. 16 kinds of measuring unit are very non-scientific because that is not by weight but by bulk or volume. Thee are many food making terms which are 179 kinds of prepared cooking term, 22 kinds of cutting term and 16 kinds of boiling term. And 20 kinds of expression of taste can be seen in this book. Food serving methods are D'ockiserving method, fruits and dried food serving methode in chanhap (food packed in a nest of boxes) Guksoo serving method, Jock serving method, fruits serving method, Seup serving method etc. Table setting methods ae 9 sets of dinner, 7 sets of dinner, 5 sets of dinner, side table setting, liquor table setting, Sinsollo table setting, food's dab table setting etc.

  • Sit to stand(STS) movement is one of the most common activity in daily life. In addition, Korean traditionally stand up from various sitting heights in one's daily life compared to other foreigners. As Korea enter rapidly to the aging society, needs of the elderly's independent life are increasing. Therefore the importance of research about the analysis of elderly's activity in daily life is rapidly increasing. In this study, we analyzed joint movements and changes of muscle length during STS(sit-to-stand) at various sitting heights(table seat, bath seat, bottom) in the Korean elderly's daily life by using the motion analysis and musculoskeletal modeling. Ten Korean elderly and young were participated in this experiment. Three heights of sitting posture which could represent typical sitting in Korean daily life were chosen as table seat(42cm), bath seat(21cm) and bottom(0cm). As the results, the elderly showed both smaller knee/hip flexion and larger trunk flexion relatively in comparison to the young during table seat STS. The elderly also showed larger dorsiflexion and smaller ROM of knee, hip, trunk compared to the young during bath seat STS. Additionally, the elderly showed larger plantarflexion, hip flexion, smaller knee flexion and trunk flexion during the first half of bottom STS and larger knee flexion, hip flexion and trunk flexion during the second half of bottom STS. In addition, we could know contraction and relaxation characters of major muscles in lower limb during various STS through the analysis of changes in muscle length by musculoskeltal modeling.

  • New human sense of value in Knowledge Society of 21th Century is reestablished by that it demanded new thinking for changed today's stage. Reestablishment of new human sense of value is considered by tradition and custom, and now then today's social standard due to focus. Productive human sense of value do to recreate for all round human relations and fertility human life demand it. Korea National Statistical Office(http://www.nso.go.kr-Dec 20. 2005) was officially announced it. that Korean Life Table(2003) presented the reminder of human life and roughly equation model of 'the reminder of human life' is 'Korean average longevity of human life-Present Korean age=About the reminder of human life' on the basic 2003 year. And then we will live a life worth living for our remaining day

  • 복숭아혹진딧물(Myzus persicae $S\H{u}lzer$)의 성충 발육과 산자수를 $15-32.5^{\circ}C$, 상대습도 60-70%, 광주기 16L:8D 조건에서 조사하고 생명표를 작성하였다. 복숭아혹진딧물 성충은 $15-25^{\circ}C$까지 수명이 $13.1{\sim}8.4$일로 온도의 상승에 따라 성충기간이 짧아졌으며, 산자수는 $20^{\circ}C$에서 40.8마리로 최고치를 보였으나 $15-27.5^{\circ}C$까지 산자수 차이에 유의성이 인정되지 않았다. 다만 $30^{\circ}C$에서는 8.4마리로 고온에 영향을 받은 것으로 보인다. 또한 복숭아혹진딧물 성충의 일일 산자수는 $25^{\circ}C$에서 5.1마리였고, $15^{\circ}C$$30^{\circ}C$에서는 모두 2.8마리로 온도가 높거나 낮아지면서 일일산자수가 적어졌다. 온도별 총 산자수를 이용하여 작성한 산자 모형을 보면 $18.3^{\circ}C$에서 51.0마리로 최고값을 보인다. 또한 약충 발육시 사망률과 성충 수명, 산자수를 이용하여 생명표를 작성하였는데 복숭아혹진딧물은 Ro가 $27.5^{\circ}C$에서 36.5, $r_m$은 0.4, Dt는 1.6, 기간증가율은 1.5, 세대기간은 8.1로 $27.5^{\circ}C$가 복숭아혹진딧물 증가에 가장 적합한 온도로 나타났다.

  • In this paper, optimal spot weld layout design of the shock tower structure is performed for increasing fatigue life of spot weld and fatigue life of shock tower simultaneously. To predict the fatigue life, linear static analysis is conducted then fatigue analysis is performed by applying random vibration load. To optimize the spot weld layout, design variables that have an effect on spot weld fatigue life are selected. Based on the DOE table, spot weld fatigue analysis is conducted. Finally, response surface model is made from fatigue analysis results and optimized spot weld layout model which increases fatigue life of sport weld and fatigue life of shock tower is determined.
