The safety of ships is one of the most important concerns in terms of the environment and human life. A ship in bad condition is likely to be subject to accidents, such as collision and grounding. When a ship has minor collision damages in the form of circle or ellipse, its ultimate strength will be reduced. It is important to evaluate the reduction ratio of a ship's ultimate strength that results from damages. The strength reduction of a plate with a cutout in the form of hole has been treated by many researchers. A closed-form formula for the reduction of ultimate strength of a plate, considering the effect of several forms of cutout, has been suggested. However, the structure of ships is composed of plates and stiffeners so-called stiffened plates and it is likely that plates and stiffeners will be damaged together in collisions. This paper investigates the effect of minor collision damages on the ultimate strength of a stiffened plate by using numerical analysis. For this study, the deformed shape of minor collision damages on a stiffened plate was made by using a contact algorithm and was used as the initial shape for ultimate stress analysis. Then, a series of nonlinear FE analyses was conducted to investigate the reduction effects on the ultimate strength of the stiffened plate. The boundary conditions were simply supported at all boundaries, and the tripping of stiffener was neglected. The results are presented in the form of reduction ratio between the ultimate strength of an original, intact stiffened plate and that of a damaged stiffened plate.

We examined the folate intakes and assessed folate nutritional status of Korean women with childbearing potential. A total of 91 healthy women aged between 15 and 49 participated. They were divided into three groups by their age : A(15-24 yrs), B(25-34 yrs) and C(35-49 yrs). Folate intakes were determined by direct analysis. The foods consumed for 24 hours were collected proportionally and assessed folate. Their blood drawn in fasting state were analyzed folate levels. Folate contents of food homogenate, plasma and erythrocyte were determined a microbiological method using Lactobacillus. casei (ATCC 7469). Prior to the micro-assay, the food homogenate were treated with alpha-amylase, protease and folate conjugase. Mean daily folate intake of the total subjects was 145.8$\mu\textrm{g}$/d and in each group of A, B, and C was 114.0$\mu\textrm{g}$/d, 141.6$\mu\textrm{g}$/d, and 164.6$\mu\textrm{g}$/d, respectively. That of group C was significantly higher than that of group A(p<0.05). However, those of all the groups were lower than compared to the Korean Recommened Dietary Allowances(RDA) for folate. Especially the subjects in the group A consumed folate least that was below the half of the Korean RDA. The mean energy intake of all subjects was 1638㎉/d and those in each group of A, B, and C did not meet the Korean RDA for energy. The energy intake were significantly correlated with folate intakes(r=0.5050, p<0.001). Mean plasma and erythrocyte folate concentrations of total subjects were 6.9ng/mL and 266.3ng/mL, respectively. None were found to be deficient both in plasma(<3ng/mL)and erythrocyte (<140ng/mL) folate levels. There was only one subject who had red blood cell folate level below 157ng/mL concentration. These results show that folate status of the Korean women of reproductive age is not much bad. But it should be better that letting them improve their folate status by increasing energy intake, choosing high folate foods.

In spite of the bad conditions of fashion companies: the number of licit wear consumers in Korea are increasing because knit wear gives a body with an comfort action. Domestic knit wear industry, however, doesn't have any standard fur satisfying consumers'needs and for quality estimation on that. So we examined the knit wearers'conception of the quality to broaden the knowledge of knit wear and produce better products. The purpose of this study was to find out the factors of wearer's perception. This study carried out through a qualitative approach. The subject of this study were 17 single women who were 20's and living in Seoul and Kyoungki province. The item of this questionary was as follow: 1) what they know about knit wear and how much they are satisfied with that 2) what the wearers think the problems of knit wear are 3) how knitted wear industry can satisfy consumers's needs and take into account consumer feedback in product development The results of this study were summarized as follows. 1. The wearers had no knowledge about materials, sewing methods, patterns, knitting methods, and gage. 2 The wearers didn't recognize the differences between the products by famous brand and obscure conventional market. For that reason, the high price knit wear wont satisfy wearer. 3. The wearers didn't prefer the revealing their body shapes. 4. Laundering was the big problem which was they chosen the knit wear. They take it for granted that the knit wear needs dry-cleaning or hand-washing. Knit wear industry tries to make it easy laundering by development knit material.

This nutritional survey was conducted from January 20 to February 8, 1994, in order to investigate the nutritional knowledge, food habits, nutritional attitude, food preferences and nutrient intakes of housewives living in Andong district, rural area of Korea. The subjects of this survey were 181 rural housewives living in Andong area. The completely answered questionnaires were analyzed for nutritional knowledge, food habit, nutritional attitude, food preferences and nutrient intakes of rural housewives. The results obtained are summarized as follows: The subjects had a high level of perceived knowledge (79.9%), that is the knowledge that each subject believed she had, but the accuracy of the knowledge was only 66.6%. The average nutritional knowledge score was 7.93 out of possible 15 points, and food habit score was 5.08 out of 10 points. Most of the subjects belonged to "Fair" or "Poor" food habit group, which is considered to be relatively bad. With increasing age, the percentage of perceived knowledge, accuracy, and nutritional knowledge score were getting lower. Food habit score and nutritional attitude score were getting lower with increasing age, too. The correlation between nutritional knowledge score and food habit score was low(r=0.01). The correlation between nutritional attitude score and food habit was low, too(r=0.15). Food preferences for kimchi, cooked rice, potato, milk, beef, chicken, and carrot were high. Average calorie and protein intakes of the subjects were 1915.7㎉ and 77.0g respectively. The ratio of caloric nutrients intake was carbohydrate 65.9%, protein 14.9%, and fat 19.2%.

This study was initiated to find the characteristic awareness of disease in Korean culture and then, with its applying to psychological nursing, to help cancer victims cope with their disease. Research period was from Dec. 1, 1989 to Aug.3, 1992. The research method, while the method of face-to-face interview with 33 cancer victims were mainly adopted, was to identify the causal perception through analyses of literature and traditional sayings deeply rooted in Korean culture. The causal perceptions were differentiated into 4 sections, which apply to 32 cancer victims with Q-sorting. Be-ing coded into grades from 1 to 9, the data were analyzed with the aid of Quanal program on PC ; in analyzing Q-factor principal component analysis method was used. The results were revealed as follows : 1. Subject victims owe their disease to 1) the omnipotent and animating powers in Shamanism rooted in Korean culture, 2) their intimate persons, i.e. their husband, wife, children, or other fellows ameng their groups. 3) victims themselves, and 4) nowhere, for they thought the disease is the struggle with their own self. 2. In Q-methodology analysis, cancer victims are categorized into 5 types. The first type, self-mastery type, consisting of 11 subjects, has the characteristic of overcoming their disease with their own strong will or by the help of the Omnipotent God, which is estimated to be the ideal type to cope with the disease. The second type, omnipotent & animating powers-dependent type, consisted of 7 subjects, who have the causal perception of traditional shamanism. The third type, intimate person-dependent type, consisted of 4, all of whom are women and whose causal perception has the characteristic of the their complains about each member of their family, espectially about their husband. The fourth type, fate-recipient type, was the com-plex form of the first and the second types. It consisted of 6 subjects, to whom cancer had meant bad fate coming on them but had to be overcome by their strong will. The fifth type, personal type, consisted of 4, whose causal perception is toward themselves personality It is hoped that the study provide the chance of developing nursing intervention to help cancer victims accept and overcome their disease as their own reality instead of attributing to anyone or any-thing else.

The purpose of this study was to investigate characteristics of teenagers' perceptions to bullies according to the classification types of Q-methodology. The results of the analysis were classified in 5 types. Type 1, which was the type geared foward solution, showed that they expressed a strong attitude of sympathy and protection towards the victim. However, they had harbored rage and hostile feelings against the assaulter. For example, when they witnessed the bully in action, they positively intervened in the situation. Type 2, which was the observer type, showed that they thought the victims were to blame for their misfortune. Also, when a friend who was left out in the cold by his classmates, they were just watched without showing any special interest. Type 3, which was the type of conflict, indicated that they believed that the both the victim and the assaulter should have responsibility. In contrast to the previous type, they had sympathy for the friend who was left out in the cold by his classmates, they had the dual feeling that intended to use the bully under the situation with his friend. Type 4, which was the type of assenting, indicated that they assumed an indifferent attitude to the situation, while they implied assenting to the situation of the friend who had a bad relationship with them. Type 5, which was the negative type, showed that they had the negative view to the situation of bully itself so that they did not recognize the bully as the method of revenge for whatever reason. The results of the study showed that the bully increased the factor of stress to school life of the victim or assaulter, even in the subjective position. The perception of the bully should change according to the characteristics of the types of people and it is necessary to study how to cope with the situations.

Purpose: The aim of this study is to examine the effects of egg consumption and suggest proper guidelines for consumption of eggs by determining the relationship between eggs and cholesterol. Methods: Literature review was conducted on the relationship between nutritional, functional properties of eggs and serum cholesterol, as well as cardiovascular disease. Results: Eggs, which are a good protein food with complete amino acid composition, contain vitamin A, riboflavin, vitamin $B1_2$, folic acid, vitamin D, vitamin E, vitamin K, calcium, iron, choline, selenium, ${\beta}$-carotene, lutein, zeaxanthin, etc. However the egg yolk has a high cholesterol content, which is associated with chronic diseases, including heart disease and hypertension. As a result, its intake is subject to regulation. Outbreak of heart disease by yolk intake can show different results depending on the characteristics of the subjects, amount of egg intake, and the implications of other foods eaten. It is difficult to determine whether eggs are beneficial, as they are the main supplying source for other major nutritive elements as well. Several research studies insist that when cholesterol intake increases by 100 mg, the level of serum cholesterol increases by 2.2~4.5 mg/dL and when serum cholesterol increases by 1%, the risk of heart disease increases by 2%. This indicates that a large intake of eggs can increase the risk of heart disease. Although the cholesterol of egg yolk and serum cholesterol are correlated, it is insufficient to conclude that only cholesterol and not other components are related to heart disease. In fact, other components in egg such as various unsaturated fatty acids and phospholipids could be related as well. Rather than concluding egg as a 'good' or 'bad' food according to its cholesterol content, it is important to define egg as a part of dietary patterns. Conclusion: Generalizing an indiscriminate and uniform amount of egg intake for all seems inadequate. However, patients with diabetes or heart disease should pay particular attention to the amount of egg intake. As for the norm, eating egg with vegetables as a substitute for other animal products seems beneficial.

The purpose of this study was to investigate sodium consumption and related psychosocial factors among hypertensive patients and normal adults through questionnaire development. The Theory of Planned Behavior provided the basis for the study. The mean blood pressure of subjects was 117. 1 mmHg/78.55mgHg in normal adults(N-218), 159.65mmHg/102.05mmHg(systolic/diastolic) in hypertensive group(N=219) and the sodium consumption was 5219.4${\pm}$1821.3mg in normal adults and 4631.4${\pm}$1749.1mg in hypertensive group. The results of Multiple logistic regression analysis showed that the odds of being hypetensive group were increasd as subjects felt that dalty food (OR=1.5) (OR=0.8). The odds of beign hypertensive group increased as subject received more support. With respect to perceived control, the odds of being hypertensive group were increased as subjects felt more confident in contolling salty intake when spouse likes to take salty food(OR=1.4). In contrast, subjects felt less confident in contolling sodium consumption when they took medicine(OR=0.8). Study findings revealed that all three factors, attitudes, subjective norms, and perceived control contributed to the model for explaining intentions, with subjective norms being most important. This findings provided the empirical evidence for the TPB in explaining salt intake. This study suggest that educational interventions for hypertension patients focus on changing sodium consumption through changing attitude toward high sodium consumption, subjective norms, perceived control over reducing sodium consumption of specific situations, specially subjective norms and perceived control. In addition, interventions may include strategies to change attitudes toward sodium consumption by helping hypertensive patients realize negative beliefs and modifying positive beliefs and to elicit and maintain subjective norm from doctors, family and neighbors, and to increase control beliefs for reducing sodium consumption.(Korean J Nutrition 33(8) : 833-839, 2000)

This study identifies the foot shapes of elderly women by classifying foot type according to the 3D shape of the foot and 2D sole type analyzing individual characteristics. The subjects were 295 elderly women over 60 years of age who live in Gwangju. A foot scanner (K&I Technology $Nexcan^{(R)}$) was used to obtain three-dimensional shapes of feet and a flat bad scanner (HP Scanjet G2410) was used to obtain the two-dimensional shapes of soles. The anthropometric measuring items consisted of 59 items estimated on the right foot of each subject. Data were analyzed by various statistical methods such as factor analysis, ANOVA and cluster analysis using the SPSS 19.0 statistical program. To classify the side type of elderly women's feet, three-dimensional measurement data were analyzed for the 27 measurement items using factor analysis and 6 factors were extracted (inside height and side gradient, ankle thickness, toe height and midfoot size, lateral malleolus height, instep, and heel height and gradient). A cluster analysis resulted in three types: 36.5% belonged to Type 1 (high forefoot and high midfoot), 31.1% belonged to Type 2 (high forefoot and low midfoot), and 32.4% belonged to Type 3 (low forefoot and high midfoot). The distribution was relatively even. For the sole, 8 factors were extracted (ball width and medial foot protrusion, lateral foot protrusion, forefoot and hindfoot length ratio, ball gradient, heel size, toe breadth, lateral ball length, and foot length) and a cluster analysis resulted in three Types (Type H, Type D, and Type A). The largest proportion (42.7%) belonged to Type H, which is the same as the elderly men's case.
