Environmental issues are getting imrx>rtant and the polluted environment is now c considered as one of the serious social problems which we have to face. As a result, most people hate an night soil-treating establishment to be built near their village. This paper is intended to reveal the present situation of Sanitary Environment Bureau in Iksan City and its treatment of night soil. The conclusions are as follows 1. The mean quantity of treated night soil per day was approximately 126kl In 1995, and the treated quantity per month was largest in the months from May to August, but smallest in January and February. The quantity of the largest month doubled the one of the smallest, and it is considered to be because the microorganisms are more active in the warm season than in the cold season, being a a ble to process more night soil. 2. The after-treatment sewage water is regarded as being in an optimalcondition because the examination of the water discharged from the establishment revealed the result of BOD 16.67mg/l and SS 14.78mg/l in 1995. 3. The expense for treating human waste was ￦19,582 in Iksan Sanitary Environment Bureau and it was considerably lower than the average expense through the nation, i.e. ￦22,000-25,000. But the cost should be expanded for keeping outworn equipments from the old age. 4. It is desirable for the Bureau to open the establishment so that any adult or student can come into it and watch all the treating processes. It will help the citizens understand the need for the establishment in spite of its nasty and ugly impression. Other cities or countries have to follow this model and try to provide their citizens with a cleaner environment by investing more fund technology for it.

As the stainless steel has good corrosion resistance, mechanical property and ease of manufacture, it has been studied as the candidate material of metallic bipolar plate for automotive PIMFC. But, metal is dissolved under fuel cell operating conditions Dissolved ions contaminate a membrane electrode assembly (MEA) and, decrease the fuel cell performance. In addition, metal oxide formation on the surface of stainless steel increases the contact resistance in the fuel cell. These problems have been acted as an obstacle in the application of stainless steel to bipolar plate. Therefore, many kinds of coating technologies have been examined in order to solve these problems. In this study, stainless steel was coated in order to achieve high conductivity and corrosion resistance by several methods. Contact resistance was measured by using a tensile tester and impedance analyzer Corrosion characteristics of coated stainless steel were examined by Tafel-extrapolation method from the polarization curves in a solution simulating the anodic and cathodic environment of PEMFC. Fuel cell performance was also evaluated by single cell test. We tested various coated metal bipolar plate and conventional and graphite were also tested as comparative samples. In the result, coated stainless steel bipolar plate exhibited better cell performance than graphite to bipolar plate.

This is a study to analyze rural area women's perception and practice of prenatal care, which is the fundamental of the education of children. Further, it was aimed to provide basic data for ideal childbirth, upbringing and household management process. For that object, questionnaires were distributed to women living in Yongdong region to judge the level of general understanding on prenatal care. Research was done from three different aspects; dietary life, emotion control and health management. Percentages were drawn out to see the general tendency. The following results were discovered from data analysis: 1. Most subjects of the survey knew well about prenatal care. They had acquired that knowledge from their parents. Most thought that prenatal care is necessary. They answered that they think prenatal care has more or less effect on the fetus. The first dime they thought about prenatal care was after they found that they were pregnant. 2. The subjects knew well about dietary needs for pregnant women carried out much of what they knew. Intake of sufficiently nutritious food is somewhat difficult, but foods that are regarded as bad were avoided thoroughly. It appears that most women have much concern about what they eat during pregnancy. 3. Most of the subjects understood that the emotional stability is necessary but it wasn't put into practice so well as in dietary life. Especially, attitudes connected with emotional development like, "Look or hear only what is good (for the fetus)" were practised little. Efforts for self-restraint as "Not to hate or pick out others' defects or talk bad about others" were appeared to be great, and it is practised well, too. 4. The subjects were well-informed on health area, but practised little. Behaviors for health improvement as to "Lead a regular daily life for health" or "Not to take a long trop" were practised very faithfully. The results of the survey showed that passive attitudes related to tabooed food, self-abstinence and cautions for bodily safety were prevalent; more positive and progressive disposition missing. That is, full perception and active practices for caloric intake, emotional improvement and physical strength development are needed.

Purpose: This study is aimed to identify the health-related quality of life for children with a mentally ill parent. Methods: The 13 participants were school-aged children whose parents were registered at the D Regional Mental Health Welfare Center. Data were collected using one-on-one interview with illustration cards and analyzed by content analysis. Results: The participants were living a difficult life in anxiety amid a reversal of parent-child role, such as doing housework and taking care of their parents. The study revealed a love-hate family relationship that the participants wanted parental recognition and attention but they were frustrated by insufficient parental care and sibling conflict. Nevertheless, they only had each other themselves to trust and rely on. Their mixed health awareness and negative emotions were influenced by parents. Some of participants were exposed to dangerous environment such as domestic violence, and they need support system for help in difficult situations. Sometimes they felt happy by satisfying physiological, social, and self-esteem needs. They also showed a positive potential that they were matured more than peers through the experience of overcoming difficulties. Conclusion: Not only were there not enough attention and support for the children with mentally ill people, but they were also exposed to an environment that threatens their physical or mental health. Therefore, to improve their health-related quality of life, there should be some integrated support of the community health system to cope with the challenges they face.

Alkali treatment following acidic hydrolysis (ATAH) of defatted soybean is currently used to reduce the level of 3-chloropropane-1,2-diol (3-MCPD), a known carcinogen, in commercial Korean soy sauce. 3-MCPD concentrations in commercial soy sauces made by ATAH were compared with those made only by acidic hydrolysis, and products that combine soy sauce made by acid hydrolysis (followed by alkalinization) and enzymatic methods. The four soy sauces made by ATAH had lower 3-MCPD concentrations (below 0.078 ppm) than 4 commercial products (0.147∼0.481 ppm) made only by acidic hydrolysis. On the other hand, 3-MCPD concentrations in 4 commercial products made by combining soy sauces made enzymatically with that made from acid (with alkali treatment)-hydrolyzed soybean protein in varying ratios were in a range of 0.016∼0.053 ppm. The 3-MCPD concentrations in commercial Korean soy sauces, with the exception of 2 of the soy sauces made only by acidic hydrolysis, were lower than allowable limit of 0.3 ppm in Korea. These results demonstrated that currently produced commercial soy sauces on the Korean market hate toxicologically save 3-MCPD concentrations. It is also provides evidence that ATAH is an effective process for reducing 3-MCPD concentrations in commercial soy sauce.

The purpose of this study is to present basic data to be used in the development of a sexual education program to create an affirmative sexual egoism. We classified the types of subjectivities and revelation attitudes of menstrual experience in 5th and 6th elementary school girls. The analytic method of data was a "Q-method" (William Stephenson). The results of this study classified four-types. The first type is an "open type". Girls of this type accepted menstrual experience as neither disease nor an embarrassment but as an important and natural course for a woman. The second type is the "concealing type". Girls of this type keep silent and conceal menstruation from persons because they consider it shameful or disgrace. The third type is the "conceited type". Girls of this type think that menstruation is painful-but only for them. Also, they accept such pains being 'grown-up'. The fourth type is the "tomboy type". Girls of this type want to be an eternal child; they hate being born a woman and think menstruation is troublesome. As a result of this research, we have concluded that it is necessary to educate girl students before they experience menstruation in order to develop positive attitudes towards sexuality and in so doing, aid them through adolescence.

Purpose - This study aimed to investigate the effects of customer relationship quality and perceived power on complaint behaviors in a context of service failures in a restaurant. Two different types of complaint behaviors were employed: personal complaining that disappointed customers directly approach to a service manager and public complaining that customers ask for related institutions, like consumer protection organization, for help. This study also examined the moderation effects of brand reputation on the relationships between customer perceived power and two types of complaint behaviors. Research design, data, and methodology - The author developed a structural model in which customer relationship quality is proposed to affect customer perceived power, thus influencing personal and public complaint behaviors. The model also includes the moderating role of brand reputation; the effect of customer perceived power on two types of complaint behaviors becomes stronger when brand reputation is high. To analyze the research model, a survey based on a scenario regarding the contexts of service failures in a restaurant was conducted toward 126 female college students. SPSS 22.0 and AMOS 21.0 were utilized to test the hypotheses. Results - The findings are as follows. First, customers who had positive relationships with a restaurant are more likely to perceive that they have strong power to influence the service provider. Second, customer perceived power had a significant and positive effect on both personal and public complaint behaviors. Finally, when the brand reputation for a restaurant is high, dissatisfied customers who think they can exercise influence to the restaurant complain more actively toward the service provider. Conclusions - The findings of this study are against the traditional viewpoint on customer loyalty that loyal customers compared respond more generously to the mistakes of a company, but consistent with the 'love becomes hate' effect proposed by Grégoire, Tripp, and Legoux(2009). In complaining contexts, companies should manage customers with positive and strong relationship more carefully and strategically to prevent the expansion of economic and social risks from customers' complaining behaviors. This is more significant for companies with strong brand reputations.

Physiological response of Panax ginseng var. atropurpureacaulo (purple stem variety, Pg) to light was reviewed through old literatures and recent experiments. Canopy structure, growth, pigment, leaf anatomy, disease occurence, transpiration, photosynthesis (PS), leaf saponin, photoperiodism and nutrient uptake were concerned. P. ginseng var. xanthocarpus (yellow berry variety, Px) and Panax quinquefolius(Pq) were compared with Pg if possible. Compensation point(Cp) increased with increase of light and ranged from 110 to 150 at $20^{\circ}C$ but from 140 to 220 at $30^{\circ}C$ with 4 to 15 Klux indicating occurence of light and temperature-dependent high photorespiration. Characteristics of Korea ginseng to hate high temperature was well accordance with an observation 2000 years ago. Korea ginseng showed lower Cp and appeared to be more tolerant to high light intensity and temperature than American sheng although the latter showed greater PS, stomata frequency and conductance, chlorophyll and carotenoids. Px showed lower PS than Pg probably due to higher Cp. Total leaf saponin was higher in leaves grown under high light. Ratio or diol saponin and triol saponin(PT/PD) decreased with increase of light intensity during growing mainly due to decrease of ginsenoside $Rg_1$ but increase of ginsenoside Rd. Leaves of Pg and Px had $Rg_1$ but no $Rb_3$ which was only found as much as $20\%$ of total in Pq leaves, and decreased with increase of light intensity. Re increased in Pg and Px but decreased in Pq with increase of light. PT/PD in leaf ranged 1.0-1.5 in Pg and Px but around 0.5 in Pq. Korea ginseng has Yang characteristics(tolerant to high light and temperature), cultured under Eum(shade) condition and long been used for Yang efficacy (to build up energy) while Pq was quite contrary. Traditional low light $intensity(3-8\%)$ for Korea ginseng culture appeared to be strongly related to historical unique quality. Effect of light quality and photoperiodism was not well known. Experiences are long but scientific knowledge is short for production and quality assessment of ginseng. Recent scientific knowledge of ginseng should learn wisdom from old experiences.

The purpose of this study was to analyze effect of nutrition education after executing education nutrition with the nutrition education textbook, reconstructed 12 units, focused on older elementary school children and to evaluate interest and understanding of textbook. The subjects were 4th grade children. The results were as follows. The most interesting lesson contents was 'obesity(16.3%)', and the next were 'food poisoning' (13.3%), 'kimchi'(13.3%), and 'Korean table manners'(10.2%) in the 12 unit. Children who attended education nutrition answered 'interesting'(94.1%), 'understand easily'(97.1%) about the developed textbook. With regard to change in nutrition knowledge after education, the percentage of correct answers was increased in most of question except 'reason of snack' and 'weight-control'. And the total score of nutrition knowledge was risen(p<0.01), because the ratio of correct answer of 'importance of breakfast'(p<0.05) and 'nutrition labeling'(p<0.01) was improved especially. The ratio of desirable snack time 'between lunch and dinner' was higher after education(91.2%) than before(55.2%)(p<0.01). After education, the choice of 'Fruit and vegetable' of which desirable snack food was increased. Both the choice of 'bread' and 'fast food', a factor of oversupply calorie, was decreased. And after education, the percentage of sound snack place 'home' was improved. In regard of a meal environment, the percentage of 'every wash hand before eating' is 65.1% and there is scarcely change after education. Before education, children answered 'use it rightly'(82.4%) about 'how to eat with spoon and chopsticks', but it is lower after education. The ratio of 'leave food sometimes or always' is 47.1% before education, and the ratio of leftover food tend to decreased in school lunch. Relate to reason of leftover, the percentage of 'because of hate food' tend to decrease. This results suggests that the activity-centered nutrition education can help to change food behaviors and increase nutrition knowledge level of school children.
