  • Health care for women regularly focuses on the reproductive system to the exclusion of other health needs. The lack of research focusing on women's common health issues is a major problem to the enhanced optimal level of women's health. Health care providers have to recognize biological and social differences between men and women. This study was conducted to identify the baseline data and their correlation of health perception, health behavior, and health status of adult women for developing nursing intervention. The study was a descriptive correlational design. A convenient sampling method was used for collecting data from 103 adult women, over 18 years of age, during the period from Sep 1 to Nov 30, 2001. The study's subjects were interviewed using a structured questionnaire. The instruments for this study were the health perception scale modified by Lee(1985) based on the tool developed by Ware(1977) and Jenkins (1966), and the health behavior scale by Ko, Kumja(1987). Health status was measured by the short form Cornell Medical Index(CMI) modified by Nam, Hochang(1965). The data were analyzed SPSS PC+, by frequency, mean, t-test, ANOVA, and Pearson correlation coefficients. Also, the Duncan test was utilized for a post hoc test of ANOVA. The results of this study are as follows: 1. The mean score for health perception was 3.02(S.D=0.39) on a 5 point scale. 2. The mean score for health behavior was 3.08(S.D=0.43) on a 5 point scale. 3. The mean score for health status was 18.54 on 58 items. The mean score for physical symptoms of a subscale of health status was 11.30 on 36 items and the mean score for psychological symptoms was 7.37 on 22 items. 4. The relationship of sociodemographic variables to health perception. health behavior, and health status of women.: 1) There were significant differences in the scores of health perception by disease experience(t=-3.37, p=0.00). 2) There were significant differences in the scores of health behavior by age(F=10.52, p=0.00), height(F=4.73, p=0.01), marital status(t=-5.56, p=0.00), educational background(t=2.90, p=0.00), and drinking or non-drinking(t=2.17, p=0.03). 3) There were significant differences in the scores of health status by educational background(t=2.28, p=0.02) and disease experience(t=2.61, p=0.01). 5. Health perception showed significant positive correlation with health behavior(r=0.39, p=0.00). Health perception showed significant negative correlation with health status(r=-0.44, p=0.00), that is, the more women perceived health, the less she complained about unhealthy symptoms. Health behavior had no significant correlation with health status but showed a positive correlation with psychological symptoms of a subscale of health status(r=-0.19, p=0.05). Many of the leading causes of disease are preventable through changes in health perception and behavior. The need to increase individual awareness of relationships among health perception, health behavior, and health status and to enhance knowledge regarding the long-term effects of positive health behaviors, is an important nursing strategy for women's health promotion.

  • The increasing rate of obesity in school aged children has become a conspicuous social phenomenon in Korea. This has been linked to greater economic growth, increasingly westernized dietary habits, and a consumer driven society. Given that obesity can lead to social exclusion or unfavorable attention by other students in a school setting, the design of plus-size garments have become important for effective appearance management skills. This research aimed to establish a somatotype database for obese school boys, aged 10 to 12, in order to develop a sizing system for plus-size upper garments. In order to measure somatotype of average and obese school boys, five categories were recorded; height, obesity, length of trunk, thickness of neck and chest. For obese boys, subcutaneous fat thickness and position of B.P/shoulder point factors were recorded. Obesity factor was subdivided into overall and specific ones, and while the deviation of obese body types was severe compared to the average type. Obese body type showed significantly higher measurements in width, girth, thickness. This is linked to the fact that the frequency ratio of obesity increases with age. Stature and chest were chosen as control dimensions for boys' wear. As crosstabulation of stature(5cm interval) and chest girth(2, 3 and 4cm), and stature(5cm interval)/chest girth(3cm interval) sizing system showed, the most effective cover ratio and adaptability to the data distribution $25{\sim}75$ quartile. Based on the findings, 10 sizes were formulated for average body type, while 18 sizes were formulated for obese type, whose size cover ratios were 48% and 62.9%, respectively. The primary ranges of stature were $145cm{\sim}150cm$, while those of chest girth were $79{\sim}82cm$. Each size was declared as "chest-somatotype{A(average)/O(obesity)-stature". This study proposed a plus-size upper garment sizing systems for obese boys, accompanied with reference measurements for suit, casual wear and underwear. The finding showed that the two systems were totally separate and not overlapping, meaning that plus-size sizing system is essential for obese school boys. The obesity type system had more size and wider range specs.

  • This experiment was conducted to investigate the effect of different nipple angles on water disappearance in growing pigs, which is defined as the water which leaves the watering device but is not consumed by the pig. This water adds to the volume of the total waste slurry. Four crossbred pigs averaging $70.0{\pm}1.4$ kg were assigned into 1 of 4 treatments using a $4{\times}4$ Latin-square design. Treatments were distinguished by the angle between nipple terminal and the perpendicular wall. These angles were: 1) NA-30 (= Nipple Angle $30^{\circ}$), 2) NA-45 (= Nipple Angle $45^{\circ}$), 3) NA-60 (= Nipple Angle $60^{\circ}$) and 4) NA-90 (= Nipple Angle $90^{\circ}$). All of the nipples were fixed at shoulder height of each pig. After a 7-day adaptation period, samples were collected from each pig for 4 days, followed by a day for change-over. Pigs were fed a 0.8 kg diet twice daily at 08:00 and 20:00 and supplied water ad libitum. Throughout the experimental period, pigs in the NA-30 treatment group showed greater water disappearance than other treatments. Water disappearance was the lowest for the NA-60 treatment group (p<0.01). The percentage of water disappearance to the water supply was significantly reduced in the NA-60 treatment group (p<0.01). Water intake was the same for all the treatment groups. The rate of water disappearance per unit of water intake was significantly decreased in pigs in the NA-60 treatment group compared to other groups (p<0.01). These results suggested that the nipple angle for growing pigs should be $60^{\circ}$ to reduce water disappearance and, subsequently, the amount of waste generated.

  • 선체는 기본적으로 얇은 판부재들의 조합으로 구성되어 있으며 이들 중 상당수는 유공을 가진 유공판(Perforated plate)으로 이루어져있다. 선체에 설치된 유공판으로서는 선체 상갑판 해치(하역시설로 사용), 선저부의 거더와 플로어(중량경감과 선박 건조 및 검사시 통로확보용), 다이어프램(중량경감 및 파이프 관통의 목적)등이 있다. 이들 유공판에 압축하중이 작용하면 좌굴과 최종강도 특성이 크게 변화할 뿐만 아니라 수반되는 면내응력도 재 분포하게 되어 심각한 문제를 발생한다. 본 연구에서는 실선에서 사용 중인 유공보강판의 모델을 조사하여 비선형 유한요소법(ANSYS)을 사용하여 종방향 압축하중이 작용하는 경우에 대해서 유공비, 웹 치수, 웹 두께 그리고 보강재 단면을 변화시켜가며, 최종강도 시리즈 해석을 수행하고, 최종강도 예측 설계식을 제안하였으며, 식의 정도성을 검증하기 위하여 유한요소해석 결과와 비교하여 정도를 확인하였다. 제안된 설계식은 초기구조설계 시 유공보강판의 최종강도 계산에 유용하게 사용되리라 판단된다.

  • Dragon robe was defined as a robe on which the principal design consisted of dragon. Dragon patterns have been used on princess robes during T'and Dynasty. In Sung, Dragon-figured robes seem to have an Imperial prerogative. Yuan took over the use of robes with dragons patterns as a definite institition. Ming tried to reject all Yuan innovations, the dragon robe was retained as an unofficial court costume. The Emperor's semiformal robes which at first had four dragon medallions, later had twelve along with the 12 Symbols(십이장문). As Ch'ing dragon robes were only intended fro semiformal use. The Later Ch'ing robes date from after 1719, when the Ch'ien-lung(건륭) introduced 12 Symbols on Ch'ing robes. The Ch'ien-lung laws were disobeyed, notably the ones that specified the number of claws on the dragons. THe Emperor's dragon robe, lung-p'ao, (용포) was described as bright yellow in color, having four slits and horsefoof cuffs. The basic pattern consisted of nin dragons, in addition it had 12 Symbols. The elaborate textile techniques reached their peak in Ch'ing Dynasty-with its Weaving and Dyeing Office in Peking, and this factories at Hangchow(항주), Soochow(소주), and Naking(남경) -helps to explain why the decay of the Ch'ing bureaucracy hastended the decline of dragon robes. In the Ch'ing Dynasty tow terms were used for dragon robe, depending on the number of claws on the dragons. Those with five-clawed dragons were called lung-p'ao, while those with four-clawed dragons were called mang-p'ao(망포). The Court felt compelled to take corrective meausres. It decreeed that Ninisters of State and other officials, who had been bestowed five-clawed lung dragons, must take out one claw. Finally, the sale of ranks and the attendant privilege of wearing dragon robes gradually increased during the 18 th century, reaching its height in the 19 th century, Finally, after the Taiping Rebellion, when the Imperial Treasury was depleted by the wholesale destruction of revenue-producing lands, the Chinese government came to depend on such sales as an important source of revenue and the practice became even more widespread. The ensuing mass production of dragon robes, and the necessity of conforming to the fairly rigid basic pattern established in 1759, resulted in marked deterioration of workmanship, and a comparative monotony of decoration. The patterns on the dragon robes slight changes continued to be made in the ways of representign them. The li shui (입수) portion at the base of the robe become inreasingly wider throughout the 19th century. The background became cluttered with symbols of good fortune, scattered among the clouds and waves. As a result of all this extraneous decoration, the dragons were so crowded that they had to shrink back into the small size that they had originally occupied in the medallons. Kuang-hsu(광저) was a long one, allowing time for the manufacture of numerous robes. Also, it would seem likely that Occidental museums and collections would have a considerable number of his robes, in view of the widespread looting of his palaces during the Allied occupation of Peking in 1900, and the frequent sales of Late Ch'ing imperial textiles by destitute Manchu courtiers in the '20's.

  • 도심지 무선통신에서 전파전파 특성(Wave Propagation Characteristics)을 정확하게 예측하는 것은 통신 서비스 영역 결정이나 최적의 기지국 선정 및 셀 설계 등을 위해 매우 중요하다. 도심지역에서 건물 차폐영역 특성을 이용한 전파예측 모델(Propagation Prediction Model)로 CCIR모델이 있다. 이 모델은 기지국과 이동국간의 차폐 영향을 직선평면형태에서의 건물 차폐율로 나타내고 있다. 그러나 건물이 밀집되어 있는 지역이나 가시선상에 구릉이나 산이 있는 지형여건을 고려하지 않았기 때문에 예측 오차가 많이 발생한다. 본 논문에서는 이러한 문제점을 개선하기 위한 전파예측모델을 제안하였다. 제안한 모델에서는 가시선상에서 가장 큰 영향을 미치는 거물차폐에 대한 블록수와 지형여건을 고려한 건물의 차폐높이에 대한 관계식을 통계 패키지 SAS(Statistical Analysis System)로 구하였다. 그리고 고밀도, 중밀도, 저밀도 지역에서 서비스 중인 무선통신 기지국의 전계레벨 수신세기를 실측한 후, 제안한 모델과 CCIR모델의 예측 결과를 비교 분석하였다. 실측치와 비교한 결과, CCIR모델보다 제안한 모델이 고밀도 지역에서 9.71dB, 중밀도 지역\ulcorner서 9.66dB, 저밀도 지역에서 4.02dB 개선되었다.

  • 이상 기후현상으로 인해 폭풍의 강도가 커지고, 지속시간 또한 길어지고 있어 연안 피해가 점차 대규모화 되고 있다. 이러한 변화에 대응하기 위하여 기존 방파제에 대한 평가기준과 신설 방파제의 설계기준이 강화되고 있다. 최근 케이슨식 방파제의 구조적 안정성을 향상시키기 위하여 개별 케이슨이 독립적으로 파에 저항하도록 하였던 방파제 케이슨을 서로 인터로킹시키는 방안이 관심을 받고 있다. 이는 각각의 케이슨에 작용하는 힘을 분산시켜 이상파랑이 발생할 경우에도 최대파력이 저감되어 방파제의 안정성을 확보할 수 있도록 한 것이다. 본 연구에서는 케이블을 이용하여 케이슨 상부를 방파제 기준선방향으로 인터로킹시켰을 때의 파력의 분산특성에 대해서 분석하였다. 수치계산의 효율을 위해 지반과 연결 케이블은 선형 스프링으로 모형화하고 케이슨은 강체로 가정한 정적 선형모델을 개발하였다. 수치해석 결과, 입사각이 커질수록 케이블을 통하여 전달되는 파력비가 높아지고, 인터로킹 케이블의 강성이 클수록 전달 파력비가 증대되어 파력분산 효과가 높아지는 특성을 확인할 수 있었다.

  • Purpose - This study analyzes loading efficiency by loading pattern for package standardization and reduction of logistics costs, along with the creation of revenue for the revenue review panel (RRP) of Membership Wholesale Clubs (MWC). The study aims to identify standard dimensions that can help improve the compatibility of the pallets related to display patterns preferred by the MWC and thereby explore ways to enhance logistics efficiency between manufacturers and retailers through standardization. Research design, data, and methodology - The study investigates and analyzes the current status based on actual case examples, i.e., manufacturer A and Korea's MWC (A company, B company, and C company), and thus devises improvement measures. To achieve this, the case of manufacturer A delivering to MWC was examined, and the actual pallet display patterns for each MWC were investigated by visiting each distribution site. In this study, TOPS (Total Optimization Packaging Software, USA) was used as the tool for pallet loading efficiency simulations the maximum allowable dimension was set to 0.0mm to prevent the pallet from falling outside the parameters, and the loading efficiency was analyzed with the pallet area. In other words, the study focused on dimensions (length x width x height) according to the research purpose and thereby deduced results. Results - The analysis of pallet loading patterns showed that the most preferred loading patterns for loading efficiency according to product specification, such as pinwheel, brick, and block patterns, were used in the case of the general distribution products, but the products were configured with block patterns in most cases when delivered to MWCs. The loading efficiency by loading pattern was analyzed with respect to 104 nationally listed standard dimensions. Meanwhile, No.51 (330 × 220mm) of KS T 1002 (1,100 × 1,100mm) was found to be the dimension that could bring about an improved loading efficiency, over 90.0% simultaneously in both the T-11 and T-12 pallet systems in a loading pattern configuration with the block pattern only, and the loading efficiency simulation results also confirmed this as the standard dimension that can be commonly applied to both the T-11 pallet (90.0%) and the T-12 pallet (90.7%) systems. Conclusions - The loading efficiency simulation results by loading pattern were analyzed: For the T-11 pallet system, 17 standard dimension sizes displayed the loading efficiency of 90.0% or more as block patterns, and the loading capacity was an average of 99.0%. For the T-12 pallet system, 35 standard dimension sizes displayed the loading efficiency of more than 90% as block patterns (the average loading efficiency of 98.6%). Accordingly, this study proposes that the standard dimensions of 17 sizes with the average loading efficiency of 99.0% should be applied in the use of the T-11 pallet system, and those of 35 sizes with the average loading efficiency of 98.6% should be reviewed and applied in the use of the T-12 pallet system.
