This study was conducted to develop a plan for emotional labor of clinical dental hygienists by understanding the factors affecting their emotional labor. Self-administered questionnaires were distributed to 293 dental hygienists who worked in dental hospitals and clinics located in Busan and Gyeongsangnam-do from June to September in 2013. The questionnaire items used in this study consisted of 5 items of general characteristics, 2 items of characteristics related to turnover, and 9 items of emotional labor. t-test, ANOVA, and multiple regression analysis were performed using the SPSS Statistics ver. 17.0 for Windows program for data analysis. The average level of the study subjects was $69.85{\pm}12.82$. With regard to the emotional labor according to the general characteristics, the frequency of emotional expressions (p<0.037) showed significant differences in the marital status. The workplace showed significant differences in the frequency of emotional expressions (p<0.001), attentiveness of emotional expressions (p<0.002), emotional dissonance (p<0.032), and total (p<0.001). The turnover intentions showed significant differences in the frequency of emotional expressions (p<0.001), attentiveness of emotional expressions (p<0.001), emotional dissonance (p<0.001), and total (p<0.001). As a factor affecting emotional labor, turnover intention (p<0.001) and workplace (p<0.001) had an effect on emotional labor. The results showed that turnover intention and workplace were associated with the emotional labor of dental hygienists. There is a need to develop an emotional education program to make it possible to effectively manage emotional labor of dental hygienists for providing high-quality medical services of dental institutions.

The seasoned pork loin manufactured using with seasoning sauce that were prepared with 3 different composites of medicinal plant extracts ($T-1{\sim}3$). The the quality characteristics were investigated during storage at $4^{\circ}C$ for 15 days. Sensory evaluation was higher in medicinal plant extracts added seasoning pork, in particular, significantly highest in group T-1. Lightness ($L^*$) value tended to decrease with increasing storage days, redness ($a^*$) was significantly higher in the medicinal plant composites added groups (T-1, 2 and 3) than control, yellowness ($b^*$) had no significant difference among three groups added medicinal paint composites. In hardness test, raw pork (control) was lower than seasoned pork groups, but tended to increase by added medicinal plant composites. Cooking loss increased with increasing storage period, but there was no significant difference between the seasoned pork groups ($T-0{\sim}3$). The changes of pH showed lower in control than seasoned pork groups ($T-0{\sim}3$) added seasoning sauce. Moisture content decreased with increasing storage period. VBN content increased during storage. After storage for 15 days, it was significantly higher in the order of T-3 >> T-0 > T-2 > T-1.

The study was aimed to investigate the mixing ratio of kiwi and persimmon juices for the production of good quality wine by Saccharomyces cerevisiae Y28. Firstly, the optimum condition of rapidase treatment for the kiwi and persimmon juices was established, thereafter various mixing ratio (10:0, 9:1, 8:2, 7:3, 6:4, 5:5) of kiwi and persimmon was investigated regarding physiochemical properties and flavor compounds of wine. As the result, the optimum conditions were obtained as 0.3% rapidase for 1 h in kiwi and 0.3% rapidase for 3 h in persimmon. According to higher ration of persimmon, the pH of wines increased from 3.69 to 3.77, while the acidity of wines decreased from 2.07% to 1.51% at 14 days fermentation. The ranges of brix and reducing sugar in wines were decreased which ranges around 9.6 to 8.8 and 6.07 to 6.90 g/L, respectively, after fermentation. Major organic acid in wines were identified as tartaric acid, malic acid, and citric acid. A small amount of free sugar such as sucrose and glucose were detected in wines, but fructose was completely absent. The soluble phenolic contents were decreased that ranges around 1.00 to 1.25 g/L, in contrast, browning degree were increased ranges around 0.212 to 0.412 after fermentation. The major flavor components were identified as ethyl acetate and hydrazine, and 1,1-dimethyl. Importantly, phenylethyl alcohol was detected from the all wines that have a typical rose like flavor. But sensory test results and preference of kiwi-persimmon (7:3) mixing wine was better than the other wines.

Various contents of Rosa rugosa Thunb. fruit(0, 10, 20%), which is grown along the seashore of Gangwon province, were applied to apple jams having different sugar concentrations(20, 40, 60%). The resulting jams were analyzed using a sensory scoring test as well as a response surface methodology to identify the optimum conditions for the preparation of high-preference apple jams. The sensory properties based on sense of sight, smell and taste appeared to be linked to the sugar contents. It could be attributed to the presence of flavor compounds and pigments generated from the caramelization of sugar molecules during heat processing. On the other hand, rheological properties such as viscosity and spreadability were associated with Rosa rugosa fruit content, which was also verified by textural analysis of the jams. As the contents of Rosa rugosa increased, the hardness, gumminess, and chewiness of the jams decreased, which eventually might have contributed to the less thick and thus more spreadable sensory characteristics. Sensory evaluation revealed that apple jams were preferred when prepared with $\leq$10% of Rosa rugosa fruit and $\geq$55% of sugar contents. In particular, apple jams containing 10% Rosa rugosa and 60% sugar showed better mechanical qualities as well as higher sensory preference among 10 jams formulated using central composite design.

By modified method yellow corvenia(called $Y_3$) was prepared with $4\%$ salt, $4\%$ KCl, $6\%$ sorbitol, $0.5\%$ lactic acid and $4\%$ alcohol extract of red pepper to improve the quality of fermented sea food. In this study, changes of volatile compounds and fatty acid composition obtained from modified fermented yellow corvenia($Y_3$) were experimented during fermentation, comparing with conventional fermented yellow corvenia(called $Y_1,\;20\%$ of salt contents). Total lipid of yellow corvenia was composed of $78.1\%$ of neutral lipid, $21.2\%$ of phospholipid and $0.7\%$ of glycolipid. And monoeonoic acid was held $37.4\%$ of fatty acid composition of total lipid and saturated fatty acid ($34.8\%$), polyenoic acid ($27.7\%$) were followed. Saturated fatty acid($C_{14:0},\;C_{16:0},\;C_{18:0}$) in $Y_1,\;Y_3$ increased, polyenoic acid ($C_{22:6}\;C_{22:5}\;C_{20:5}$) decreased while monoenoic acid($C_{16:1}\;C_{18:1}$) in those was little fluctuated during fermentation. Thirty-three kinds of volatile component in whole volatile compounds obtained from $Y_1,\;Y_3$ at 90 days fermentation were identified, and composed of some hydrocarbons (8 kinds), alcohols (7 kinds), acids (6 kinds), aldehydes(4 kinds), sulfides(2 kinds), ketones (2 kinds), one of phenol and 3 kinds of the other components. Among the whole volatile compounds 2-ethoxy ethanol and was held $79.35\%$ in $Y_3$, whereas nonadecane was held $75.85\%$ in $Y_1$. During fermentation 8 kinds of volatile acids, 5 kinds of amines and 9 kinds of carbonyl compounds were also detected. Those volatile acid such as acetic acid, isovaleric acid, n-caproic acid, n-butyric acid were the major portion of total volatile acids in $Y_3$ at 90 days fermentation. Meanwhile, carbonyl compounds such as ethanal, 2-butanone and butanal were the major ones, while TMA held the most part of volatile amines in $Y_3$ during fermentation. From the result of sniff test, the components which are believed to contribute to the characteristic flavor of fermented product $Y_1,\;Y_3$ are deduced to be volatile acid, carbonyl compounds and amines in order. Conclusively, there was little difference in composition of volatile components, but merely a little difference in content of those between $Y_3$ and $Y_1$.

All of the subjects of the investigation (n=141) were schools that have food services under direct management. The number of students who get food services at the schools were $1,001{\sim}1,500$ students with 46.8% investigation. In school food services, fried foods were highly preferred and the biggest merits of fried foods were (in order of highest importance) 'improvement of food services satisfaction'> 'source of calories supply'> 'easiness of cooking process'. Service frequency of fried food were in the order of 'twice a week'> 'three times a week'> 'once a week', and for the factors to decide service frequency of fried food, 'preference leaning on fried food', and 'excessive fat intake' were the most considered. The most considered factors in the case of choosing fried food were 'preference' and 'calories and nutritional value'. For the cautious steps during the frying process, 'keeping after frying' was picked the most, and the reasons were 'lack of containers to keep in appropriate temperature and quality' and 'time consuming'. For preference and service frequency of ingredients in fried foods, 'chicken' and 'pork' were very high. As the result, it was analyzed that preference by ingredients matched service in school lunches by using a ranking test. Total cooking and processing time of fried foods required in school lunches were approximately $237{\pm}99$ minutes ${\sim}291{\pm}141$ minutes which showed total required time was about same no matter what ingredients were used. As the result of comparing and analyzing the processes, vegetables took less thawing and frying time, but the processing time for vegetables was more complicated since handling time before frying was longer compared to meat. In the important management process by the main groups of fried foods, the frying process was the most cautious cooking process in the category of meat or fish and shellfish used as ingredients. In addition, if vegetables were used as ingredients, storing it after frying was the process that needed the most care.

This study is aimed at investigating the compensatory education which was already implemented or is being implemented in the U.S.A. and Japan; and at studying the types of programs and their characteristics; and at sounding out the possibilities of the application of such programs in family and social conditions is Korea. In order to achieve the above mentioned objectives, the established items for the study are as follows: (1) Various types of early children's education (2) Programs of compensatory education for the disadvantaged Children (3) Head Start Program, Early Training Project and Montessori School (4) Integrated Preschool Programs (5) Day-Care Center for employed mothers We investigated the various compensatory education programs for the preschool children who are in economically, socially, culturally disadvantaged conditions. Head Start Programs were federally supported programs for preschool children and opened as summer programs in 1965 for the first time. The purpose of Head Start has been to give preschool children the kinds of experiences they need in preparation for school. The Head Start children were found to be significantly better prepared for school than the normal children. However, after six to eight months, their initial advantages had virtually. disappeared and then the simple problem with Head Start and other such programs was that little long-term good could be evidenced unless the high quality educational environment was maintained. Therefore, to solve this problem, three other programs were funded as part of the overall Head Start. These three programs are the Parent-Child Center, Home Start, and the Child and Family Resources Program. The Early Training Project for disadvantaged children was implemented by Klaus and Gray of Peabody College in 1962. The program was a field research study concerned with the development and testing over time of procedures for improving the educability of young children from low income homes. Its major concern was to study whether it was possible to offset the progressive retardation observed in the public schooling careers of children, living in deprived circumstances. Children, who were trained through the Early Training Project were superior to control groups in the test of IQ and vocabulary as well as linguistic abilities, and preparation for reading. This project showed the possibilities which could prevent preschool children from being disadvantaged socially, culturally and mentally. In 1907, Montessori School was established by Maria Montessori in Italy and her school program has been introduced at present to several countries in the world as one compensatory educations. She first began her experimental methods with retarded children, followed by disadvantaged children from the tenements of Rome. The Montessori approach futures a prepared environment and carefully designed, self-correcting materials. The Montessori curriculum presents tastes that feature sequence, order, and regularity, in addition to those that develop motor and sensory skills. She was interested in children's intellectual development and in developing good work habits. One of the latest developed programs for disadvantaged children is "Integrated Preschool Program" which has successfully integrated handicapped and nonhandicapped children. Several studies have showed that handicapped children in integrated school environments are accepted by and interact with their nonhandicapped peers. In fact, this program provides a number of potential, and perhaps opportunities for nonhandicapped children to serve as valuable resources in fostering the development of their handicapped peers. Next we turn to Japanese programs which are divided into two different types. One is Day-Care Center which was established by Child Welfare Law and the other is kindergarten organized by School Education Law. The kindergarten opened in 1876 and it has been part of school systems since 1947 by the implementation of education law, and the Day-Care Center which started in 1890 for the employed mothers. was changed into Day-Nursery by the enactment of child welfare law in 1947. The laws and operational regulations for the Day-Nursery were set up and were put in effect by the establishment standard acts of children welfare facilities, and the Day-Nursery has been operated in various types by the increasing demand, chiefly because of the socio-economical changes of family structures in both urban and suburban areas. Nursery education for physically and mentally disadvantaged children is for those who are blind, deaf and dumb, mentally retarded; physically disadvantaged by accidents or diseases. Montessori education in Japan was started in 1968 and many research groups for studying Montessori were organized. In 1977, Montessori remedial education society was also organized in which they started a number of studies; a study for developing materials; in-service training for the remedial education; and seminars and lectures, etc It is strongly suggested that we study the early educations that are being implemented in Japan and a variety of compensatory educations that were already implemented in the U.S.A. and modify them for the organization of our own model and properly accommodate them to our social needs.

This study investigated stress and the extent of climacteric symptoms in mid-life men, and examined their relationship in order to better understand the stress and climacteric symptom experiences of mid-life men, and thereby attempted to offer basic materials for the development of a health improvement program that may help increase the quality of life of mid-life men. Three hundred mid-life men whose ages were between 40 and 59 and resided in the Seoul area were subjects of this study. The data were analyzed with the SAS PC program using descriptive statistics to analyze subjects' general characteristics and variables of stress and the extent of climacteric symptoms of the subjects. The relationship between stress and climacteric symptoms were examined by the Pearson Correlation Coefficient, and stress and the extent of climacteric symptoms in relation to the general characteristics were analyzed by T-test and ANOVA. The study conclusions are as follows: 1. Subjects general characteristics The average, age of the subjects was 46 and 47.0% of them reported ages between 40 and 45. Of the subjects, 98% were married. In marriage satisfaction, those who were generally satisfied with their married life comprised 62.0% of the subjects. In terms of level of education, 95.7% were educated above the high school level. In occupational background, 59.7% had occupations related to technologies. As for religion, 42.7% had no religion. In number of children, 67.3% had 2 children. In residential status, 79,3% were living in their own homes. In terms of living arrangements, 87.7% of the subjects were living in the form of nuclear families. 2. Stress and the extent of climacteric symptoms The level of stress was scored as $2.94{\pm}0.74$, and considering that the overall examination score is $27.16{\pm}1.32$, the subjects' stress level was not viewed as particularly high. The average score of the extent of climacteric symptoms was $35.37{\pm}0.27$. The extent of sub-domains of climacteric symptoms included skeleton symptoms ($39.37{\pm}2.81$), joint pain ($39.16{\pm}3.66$), vasomotor symptoms ($35.39{\pm}3.01$), other symptoms ($36.99{\pm}3.02$), psychological symptoms ($34.68{\pm}3.01$), urogenic symptoms ($35.03{\pm}3.27$), and cardiovascular symptoms ($33.70{\pm}2.78$). 3. General characteristics in relation to the stress level The subjects' general characteristics that were significantly related to the level of stress were marriage status (F=4.38, p=.001), marriage satisfaction (F=4.56, p=.001), educational background (F=2.68, p=.012), and age (F=2.48, p=.033). 4. General characteristics in relation to the level of climacteric symptoms The subjects' general characteristics that were significantly related to the level of climacteric symptoms were educational background (F=3.26, p=.007), age (F=2.58, p=.027), marriage status (F=2.62, p=.025), and marriage satisfaction (F=2.78. p=.032). 5. The correlation between stress and climacteric symptoms The subjects' level of stress and climacteric symptoms were significantly related to each other (r=0.578, p=0.000). The subjects' level of stress was correlated with sub-domains of the climacteric symptoms including psychological symptoms (r=0.579, p=0.000), joint pain (r=0.479, p=0.000), skeleton symptoms (r=0.477, p=0.000), other symptoms (r=0.467, p=0.000), vasomotor symptoms (r=0.4615, p=0.000), cardiovascular symptoms (r=0.458, p=0.000), urogenic symptoms (r=0.401. p=0.000). In summary, the climacteric symptoms suffered by mid-life men are positively correlated with their level of stress. In addition, the climacteric symptoms were affected by the level of stress.

As a product of poverty, health means the physical, mental and social instability caused by poverty. High mortality, high morbidity, and unsatisfied needs for medical care indicate the health condition of poor people. These indicators are related to the social and psychological property. This study is to develop an effective method of nursing in the poor family which is an essential unit in the nursing field of the community and to which a fundamental approach is need as a top priority. We can make such a study, though partially, by revealing the relationship among the Health-value, Health Locus of Contol, and the Level of Self esteem. We randomly sampled 243 women who are participating in the nursing department of the comnnity nursing centers in Seoul. We investigated by using questionaries and made an analysis on the result by SAS program. The result of this investigation can summarized as follows : 1. The average age of the subjects investigated is 43.4 and the participation rate in the economic activity is as high as 49.4%. Most of them are paid daily. The average members of the family are 4.28 persons, and 80.2% of which are nuclear families. The type of housing is as follows:51.4% are monthly-rent houses. Rent houses represent 23.5%. And 43.6% of the subjects graduate the high schools 2. The level of self-esteem possessed by the subjects is 37.17. The quality of task performance(3.46) and the morality(3.53) are low as compared with the other qualities. 3. In relation to the locus of control, internality is 22.39, the influence of powerrful others represents 20.24, and the effect of chance occurance is 16.41. 4. The orderings of value scale are the physical and mental health, comfortable life, happiness, mental peace, and pleasure. The lowest order is social recognition. 5. Considering in relation to the self-esteem and the locus of control, we found out that there is a negative relationship among the self-esteem, the influence of powerful others. The lower the level of self-esteem is, the higher the influence of powerful others is. There is also a negative relationship among the detailed items such as the qualities, and the positive attitude. 6. In a significant test in the general characters of the subjects and in the level of self-esteem, we can obtain the follwing results. The higher the economic level is, the higher the level of self-esteem is. And the higher the level of satisfaction with life is, the higher the level of self-esteem is. 7. In the locus of control, the higher the economic level is, the higher the internality is. 8. In the health-level, 75.72% represent the high health -level. And the group which has the low satisfaction with life represents the high level of health-value(81.6%). With these results, we can conclude that the level of self-esteem possessed by the poor women living in the city is high and that they have the multi-dimemsional health-value even though they are living in the poor condtions. Traditionally, the poverty has been recognized as an unfavorale factor in the health care. But this study shows that the poverty is no longer an unfavorale factor and, on the contrary, it has a potential power with which people can improve their health by possessing the high self-esteem and the high health value. The ultimate purpose which the nursing task of the community has is to make the patients keep and improve their own health. So, when the nurses approach the poor patients, the nurses should put an emphasis on the individual responsibilities of the patients, and respect their own health value.
