The purpose of this study was to examine laundry behavior according to the number of households and the type of washing machine that each household used. The data was obtained from questionnaires filled out by 417 households, which included college students living in Seoul and Gyeonggi province. The results of this study are as follows: first, according to the results of survey about the number of household members and type of washing machine that household had, one or two-person households accounted for 24.0%. Regarding the type of washing machine that each household used, there were more drum washers. In households comprised of three or more persons, a higher percentage had a machine with a pulsator. Second, with regard to the method of classifying the wash in doing the laundry, all families classified the wash according to color and textile material. Third, with regard to the amount of detergent in doing the laundry, 63.5% of households used the recommended amount of detergent while 28.3% of households used more detergent than the recommended amount. Fourth, with regard to the set temperature of water in doing the laundry, 36.2% of households used cold water; this was the highest percentage. Fifth, with regard to input sequence in doing the laundry, most households put the wash in the machine in advance, and then filled the washer with water; 56.1% of households added a rinsing process for all washing processes.

This study aims to examine the patterns of middle-aged parents' intergenerational support exchange with their adult children and its effects on the happiness of the parents. The sample consisted of 765 middle-aged parents selected from the National Survey of Korean Families by the Ministry of Equality and Family in 2010. The results were as follows. First, intergenerational support exchange between parents and their adult children was categorized into four groups depending on the provider of support: parents who exchanged no support with their children, parents who only received support from their children, parents who only provided support to their children, and parents who exchanged support with their children. Second, parents who exchanged no support with their children were high in instrumental support and those who both provided and received support were high in emotional support. Third, consciousness of their children significantly affected the satisfaction level of their relationship with their children. The more the parents emphasize on the growth of their children, the more they were satisfied. Parents in the support exchange group were more satisfied when they received economic support from their children. With regard to instrumental and emotional support, parents were more satisfied when they provided support to or mutually exchanged support with their children. Forth, subjective health conditions, consciousness of their children, and household's income more significantly affected the happiness of middle-aged parents than the patterns of intergenerational support exchange. With regard to economic support, parents who only received support from their children were less happy than the other groups. With regard to instrumental support, parents who exchanged no support with their children were happier than the other groups. With regard to emotional support, parents who provided support to their children were happier than the other groups.

The purpose of this study was to determine the prevalence of obesity and to examine the eating habits of elementary school students in Kwangju. The study was carried out on 931 students(male : 454, female : 477) in September and October of 1996. The results are summarized as follows ; Obesity was defined as body mass index(BMI) that exceeds 20. The rate of obesity was 10.0%(male 4.7$\%$, female 5.3$\%$) in subjects. Subjects were divided into 3 groups : normal group(BMI〈20), mildly obese group(20〈BMI〈25), and moderatly obese group(25〈BMI〈30), respectively. With regard to frequency of skipping breakfast, 9.1$\%$ of normal children and 17.5$\%$ of mildly obese children and 33.3$\%$ of moderately obese children had skipping every morning(p$\ll$0.001). With regard to the regularity of meal time, 62.1$\%$ of normal children had ‘regular meals’but 58.0$\%$ of mild obese children and 50.0$\%$ of moderate obese children had‘irregular meals’(p$\ll$0.05). With regard to meal volume, obese children consumed much more meal volume than normal children(breakfast p$\ll$0.001, lunch p〈0.005, dinner p$\ll$0.001). With regard to try to lose weight, 22.9$\%$ of normal children and 55.6$\%$ of mild obese children and 83.3$\%$ of moderated obese children indicated they had attempted(p$\ll$0.001). The results of this study showed that the prevalence of obesity in elementary school students in Kwangju has a tendency to be increased. Obese children need to correct their eating habits. This reasserts the importance of nutrition education in children through teachers, parents and dietitians. The findings of this study should be applied to nutrition education to ensure better physical fitness of children. (Korean J Community Nutrition 2(4) : 486-495, 1997)

The Environmental problem solving model is an instructional strategy to accomplish the aim of environmental education through investigation of environmental problems and issues of the community. This study is intended to compare the instructional effect of the structured model with the unstructured model of environmental problem solving. The experimental group received the structured instruction and the control group received the unstructured instruction. There did not appear to be any significant difference between the groups in regard to knowledge but in regard to knowledge of environmental issues, the experimental group was more effective than the control group. No significant differences existed between the groups in attitude. In regard to investigating skill and evaluation of environmental issues, the experimental group was significantly more effective than the control group. The experimental group was significantly more effective than the control group in regard to environmental action skills. To foster responsible environmental behavior, environmental education a number of methodologies must be considered and learners must be trained to become problem-solving citizens. It was noted that the structured instruction was more effective than the unstructured instruction in middle school where environmental issues were not taught as an independent subject. We conclude that environmental education must be systematically constructed and taught in a manner which takes into account both its goals and the characteristics of the various learners. We conclude that environmental education must be systematically constructed and taught in a manner which takes into account both its internal goals and the situations within which various types of learners explore environmental issues and solutions.

In regard to modular systems, new methods, as well as middle and high-story unit design ideas, are currently being studied. These studies need to focus on the enhanced stiffness and seismic performance of these connections, and see that the development of fully restrained moment connections can improve the seismic performance. For this reason, this study evaluates the performance of the connections of the ceiling bracket-typed modular system through repeated loading tests and analyses. In order to compare them with these modular units, new unit specimens with the bracket connection being different from that of the traditional modular unit specimens were designed, and the results of repeated loading tests were analyzed. In the traditional units, the structural performances of both welding connection and bolt connection were evaluated. In regard to the testing results, the initial stiffness of the hysteresis curve was compared with the theoretical initial stiffness, and the features of all specimens were also analyzed with regard to the maximum moment. In addition, the test results were examined with regard to the connection flexural strength of the steel special moment frame specified under the construction criteria KBC2016. The connections, which were proposed in the test results, were found to be fully restrained moment connections for designing strong column-weak beams and meeting the requirements of seismic performance of special moment frames.

The attire of businesspersons has a significant impact on their social status and career. In accordance with the norms of the work place, the types of office attire are diversified. This research was conducted to determine the relationship between the work role of men and their attire, and how satisfaction with their work attire influences their job satisfaction. This study classifies work attire into three categories: uniform, suit, and freestyle. Data from 268 respondents were analyzed, and four work attire satisfaction factors were extracted: symbolic, quality, role function, and aesthetic factors. The group members wearing uniforms displayed a high level of satisfaction with regard to symbolism, role function, and quality; those wearing suits displayed a high level of satisfaction with regard to aesthetics; and those wearing freestyle displayed a high level of satisfaction with regard to role function and aesthetics. Overall, satisfaction with work attire was the highest in the freestyle group. For people wearing uniforms and suits, symbolism, quality, and aesthetics had a significant influence on overall satisfaction, whereas for those wearing freestyle, symbolism had a negative influence and quality had a positive influence on overall satisfaction. To conclude, work attire satisfaction had a greater effect on the job satisfaction of the men in uniforms and suits than on those wearing freestyle.

This paper describes the measurement of pulse positioning (input time) to calculate a time of arrival (TOA) that takes from transmitting a signal from the target of multilateration (MLAT) system to receiving the signal at the receiver. In this regard, this paper analyzes performances of simple threshold method and level adjust system (LAS) method, which is one of the adaptive threshold detector (ATD) methods, among many methods to calculate pulse positioning of signal received at the receiver. To this end, Cramer-rao lower bound (CRLB) with regard to pulse positioning, which was measured when signals transmitted from a transponder mounted at the target were received at the receiver, was induced and then deviation sizes with regard to pulse positioning, which was measured with simple threshold and LAS methods through MATLAB simulations, were compared. Next, problems occurring according to a difference in amplitude of signals inputted to each receiver are described when pulse positioning is measured at multiple receivers located at a different distance from the target as is the case in the MLAT system. Furthermore, LAS method to resolve the problems is explained. Lastly, this study analyzes whether a pulse positioning error occurring due to the signal noise satisfies the requirement (6 nsec. or lower) recommended for the MLAT system when using these two methods.
