When ship blocks are erected or pre-erected, most blocks will be at outdoors where they are not protected from weather and exposed to ray of the sun. A deck plate compared to those in radiation heat transfer from the sun will have higher temperature than it of ambient air, and will expand more than lower laying structures whose temperatures are similar with air. But deck plates and under-structures are connected, so the deck plate will be under out-of-plane deformation rather than expand in length. In this study, we considered the temperature difference between air and plate as a major parameter of out-of-plane deformation, and analyzed how much additional deformation would take place. In addition, when a deformation could take place was also analyzed based on the initial deformed shape of deck plate. Because the accuracy inspections of deck plate will be done during daytime, conventional accuracy check results on sunny day could make us feel unfair. Thus resonable datum about momentary additional out-of-plane deformation due to environmental effects have been determined. The real deformation values can be specified even under enlarged deformations by radiation-expansion.

This survey was carried out to investigate the correlationship between the nutrition knowledge scores and food habit of the mothers and food preference and other factors of the 272 elementary school children in Masan. The results were summarized as follows : 1. Children's most favorite food was fruits, but they dislike spicy vegetables and some fermented foods. Preferences of the male children to food groups such as protein, calcium and carbohydrate were significantly higher than those of the female children. 2. The rate of the children who take between-meal snacks 2 o 3 times a day was high and those children who skip breakfast take snacks more often. They prefer to eat fruits, dairy products and cakes as their snacks. The body weight of the children who take snacks more frequently was rather lower. 3. As the mother's nutrition knowledge scores rise, so do those of food habit scores. The nutrition knowledge scores go up according to the education degree of the mothers, but the food habit scores seem to have little to do with their education degree. The nutrition knowledge scores of the working mothers were lower than those of the non-working mothers. 4. There was strong positive correlation between the food preference on the food group and those on the other food groups of the children. As the food habit scores of the mothers rise, the children prefer to take calcium and carbohydrate group. Those who take more fat showed higher body weight.

Several days after culture, the parts around suspensor turned brown. In about 10 days the embryo started to form protocorm sending out hairs through seed coat. Around 20 days after culture, most of the protocorms emerged out of seed coat and some of them began to take green color. When observed two months after culture, the protocorn took the characteristic top-shape feature.

Objective: This clinical research is conducted to find out coping strategies and anxiety of patients with chronic pain, and the correlation between pain coping strategy and anxiety. Method: 50 subjects who came to the local oriental clinic answered the questionnaires about VPMI(Vanderbilt Pain Management Inventory) and SAS(The Self-rating Anxiety Scale). Then we researched the characteristics of pain coping strategies and the correlation. Results: 1. The mean scores of passive coping, active coping, and SAS are 29.62, 17.90, and 38.32 respectively. 2. In the analysis of nonparametric test, the female subjects tend to take more passive coping than the male. The older subjects tend to take less active coping than the younger. Subjects who reported more intense pain tend to take more passive coping. 3. There is significant difference between passive coping and anxiety. Conclusion: Pain coping strategies are related with age, sex, intensity of pain, and anxiety. The therapeutic intervention of decreasing passive coping and increasing active coping may be useful to manage the chronic pain. Further study is needed to find out more adequate inquiries of active coping.

This study was conducted to compare families eating-out behavior in relation to family life cycle in order to provide basic information on nutritional education about eating-out. The data were collected by the survey method from 440 families who lived in apartment complexes in Kyong-ju and Seoul. The structured questionnaire included items about the frequency of eating out, the choice of eating-out menus, the decision maker of the eating-out process, the attitudes toward eating out and the general characteristics of the families. The major results are as follow: 1) In the cafe of telephone delivery service, and eat-in restaurants, the subjects showed statistical significance (p < 0.01). With respect to telephone delivery service, families in Step II used it most frequently, but families in Step I rarely used it. With respect to eat-in restaurants, families in Step II used them most frequently but families in Step IV rarely used them. 2) In all the family life cycle steps, the most favorable menu was fried chicken for take-out type, Chajang noodles, fried chicken and pizza fur telephone delivery, pizza for internet delivery, raw fish and beef for eat-in restaurant, Docbokki, laver rolled rice and ramyun for convenience flood stores. 3) The wife was most influential in making decisions about the take-out type (p < 0.001). In the case of telephone deliveries (p < 0.001), the wife was the most influential in the families of Steps I and II, but the children were the most influential in the families of Steps III and IV. In the case of eat-in restaurants (p < 0.001), the husband had the most effect on the decision-making process. In the case of convenience flood stores (p < 0.001), the children were the most influential in the families in Steps III and IV. In most family life cycle steps, each of them chose their own meal. 4) from a factor analysis perspective, attitudes toward eating out have been grouped according to two factors, namely 'Advantage' and 'Nutrition'. No factor showed a significant difference among the family life cycle steps.

In Shewhart control chart, the average run length(ARL) is calculated using the mean of a conventional geometric distribution(CGD) assuming a sequence of identical and independent Bernoulli trials. In this, the success probability of CGB is the probability that any point exceeds the control limits. When the process is in-control state, there is no problem in the above assumption since the probability that any point exceeds the control limits does not change if the in-control state continues. However, if the out-of-control state begins and continues during the process, the probability of exceeding the control limits may take two forms. First, once the out-of-control state begins with exceeding probability p, it continues with the same exceeding probability p. Second, after the out-of-control state begins, the exceeding probabilities may very according to some pattern. In the first case, ARL is the mean of CGD with success probability p as usual. But in the second case, the assumption of a sequence of identical and independent Bernoulli trials is invalid and we can not use the mean of CGD as ARL. This paper concentrate on that point. By adopting one generalized binomial distribution(GBD) model that allows correlated Bernoulli trials, generalized geometric distribution(GGD) is defined and its mean is derived to find an alternative ARL when the process is in out-of-control state and the exceeding probabilities take the second form mentioned in the above. Small-scale simulation is performed to show how an alternative ARL works.

This study was conducted to analyse the dine out behaviors for single-person households using the Consumer Behavior Survey for Food in 2019. The results showed that the respondents had different dine out behaviors according to their age. 20s~30s and 40s~50s single-person household tend to dine out more frequently than 60s~70s. On the other hand, there was no significant difference in the most important selection criteria when choosing a restaurant (p=0.063), but 39.7% of 20s~30s 43.1% of 40s~50s, and the 38.3% of 60s~70s respondents selected 'the taste of food', and the young people (20s~30s) who chose 'cleanliness of the restaurant' were second with 39 people (15.5%), but in the opinion of 40s~50s and 60s~70s, 'price level' was the second most important selection criteria. Besides, frequency of buying food at home was the influencing factor for 20s~30s' monthly expenditure of dinning out, while frequency of buying food at home, monthly expenditure of buying delivery or take-out food were the factors for 40s~50s. Lastly, gender, occupation as well as monthly expenditure of buying delivery or take-out food were the factors for 60s~70s' monthly expenditure of dinning out. As many studies have shown that the expenditures single-person households play an important role in the restaurant business, the results of this study are necessary for food service industry to generate different business strategy to single-person household by age.

This study identified the brand personality of domestic take-out coffee shops and examined its effects on customer satisfaction and brand loyalty. The research subjects were college students in Busan who visited a coffee house. Overall, four major empirical results were obtained. First, five factors of brand personality were identified: "energy", "competence", "familiarity", "reliability", and "sophistication". Second, all brand personality factors had significant effects on customer satisfaction, but "familiarity" (${\beta}$=0.429) and "reliability" (${\beta}$=0.381) appeared to have the greatest effects. Third, brand personality factors had significant effects on brand loyalty, with"reliability" (${\beta}$=0.447) appearing to have the greatest effect on brand loyalty. Fourth, customer satisfaction had a significant effect on consumer brand loyalty. These results show that brand personality can be an important means of marketing differentiation in an intense competitive coffee market atmosphereto increase customer satisfaction and build brand equity.
