Physiochemical and sensory properties of muskmelon pickles were investigated under salting condition using deep seawater salt, sun-dried salt and purified salt. The changes of weight, shrinkage rate salinity and pH of muskmelon during salting time were almost nothing shown. Turbidity of pickle juice was the highest in salt solution using sun-dried salt and was almost nothing shown in deep seawater salt and purified salt. Solid content of pickle juice was higher in pickle juice using sun-dried salt than deep seawater salt and purified salt. The calcium content of muskmelon salted by deep seawater salt and sun-dried salt were increased to 4.3 times and 3.7 times, respectively. Hardness became a little higher on muskmelon using deed seawater salt ann sun dried salt than purified salt. In organoleptic result, color, flavor, taste, texture and overall palatability of muskmelon salted by deep seawater salt became higher in other salt solution (sun-friend salt and purified salt).

Total mixed ration (TMR) including concentrate diet and roughage together have been used for the ruminant animal. Relatively high concentrations of moisture and water soluble carbohydrate are representative feature of TMR. Those moisture and water can also provide a niche for bacterial growth. Therefore, a possible fermentation of TMR induced by micro-organism is generally accepted. The present study hypothesized that different lactic acid bacteria could alter fermentation of TMR and subsequently rumen fermentation. Three lactic acid bacteria, Lactobacillus paracasei (A), L. plantarum (B) and L. parabuchneri (C), were employed and 7 treatments under full factorial design were compared with control without inoculation. TMR for dairy cow was used. Significant alterations by treatments were detected at lactic acid and butyric acid contents in TMR (p<0.05). Treatment AC (mixture of A and C) and BC (mixture of B and C) showed great lactate production. Great butyrate production was found at treatment C. At in vitro rumen fermentation, treatments B, C and AB (mixture of A and B) showed significantly great total gas production (p<0.05). All treatments except treatments B and AB, showed less dry matter digestibility, significantly (p<0.05). Total volatile fatty acid production at treatment AC was significantly greater than others (p<0.05). In individual volatile fatty acid production, treatment AB and AC showed great acetate and propionate productions, significantly (p<0.05). This study investigated correlation between organic acid production in TMR and rumen volatile fatty acid production. And it was found that butyric acid in TMR had significant negative correlation with acetate, propionate, total volatile fatty acid, AP ratio and dry matter digestibility.

The purpose of this study was to identify the latent styles of attachment across four major attachment figures (i.e., father, mother, best friend, and romantic partner) for Korean emerging adults. In this study, adult attachment had two dimensions (i.e., attachment anxiety and avoidance) and was measured by the Experiences in Close Relationships-Relationship Structures (ECR-RS). Data came from 317 undergraduate students in nine universities across the nation. A latent profile analysis classified the sample into four groups. (a) The "somewhat father avoidant secure" group reported the lowest levels of attachment anxiety and avoidance across close relationships but was moderately avoidant in their relationship with the father. (b) The "overall avoidant" group had the highest levels of attachment avoidance across close relationships, but along with the "father avoidant secure" group, they had the lowest levels of attachment anxiety. (c) The "romantic anxious" group was unique with the highest level of attachment anxiety toward romantic partners while reporting relatively lower levels of attachment avoidance across relationships. (d) The "overall anxious-avoidant" group was the highest in attachment anxiety and avoidance across all of their close relationships except for attachment avoidance from best friends and romantic partners, which were the highest among the "overall avoidant" group. These four groups also differed in their levels of depressive symptoms and affection for the father and the mother. This study uniquely contributes to the literature by identifying the latent attachment styles considering four attachment figures and examining the characteristics of these attachment styles.

Purpose: The purpose of this study was to investigate the status of internet addiction, internet expectancy, and self-efficacy in elementary school students. Method: The study was carried out during the period from June 16 to July 12, 2003. The subjects in the study were 397 elementary students attending four elementary schools in Chungcheongbuk-do and Kyunggi-do. Self-rating questionnaire included general characteristics, internet addiction scale, internet expectancy scale, and self-efficacy scale. Data was analyzed using SPSS/WIN10.0 by unpaired t-test and Pearson corelation coefficient. Result: In this study, the mean score of internet addiction was 20.7. Internet dangerous group was 12.6% and internet addicticted group was 0.3%. The score of internet addiction was significantly different according to parents' concern, aversion to school life and extracurricular lecture. The mean score of internet expectancy was 27.1. The score of Internet expectancy was significantly different according to popularity among friends and easiness of making friends. The mean score of self-efficacy was 55.8. The score of self-efficacy was significantly different according to conversation with parents, enforcement of parents on learning, aversion to school life, aversion to extracurricular lecture, existence of intimate friend, popularity among friends(p=.000), and easiness of making friends. Conclusion: This study showed that prevalence of internet addiction was much lower than expected, but the score of internet addiction and internet expectancy can be different according to parents' concern and relationship with friends. Therefore parents must be concerned about their children and their school lives to prevent internet addiction.

This research explores the relationship between body image and clothing behavior in order to enhance self-efficacy among multicultural children based on a survey of 167 children. The statistical analysis indicated that children value(in decreasing order)family-esteem, friend-esteem, self-esteem, and school-esteem. School-esteem is the lowest, with boys displaying slightly higher levels of esteem than girls. A boys' self-esteem appears enhanced by higher satisfaction with overall appearance and weight; however, girls' self-esteem helped them address appearance and physical characteristics with positive attitudes. In addition, the clothing behavior of children significantly influenced self-esteem to differing degrees based upon gender. A boys' self-esteem can be increased by having them show interest in clothes rather than letting them wear similar clothes to their friends because their self-esteem can be heightened by higher interests and lower similarity. A girls' self-esteem can be augmented by the clean management of clothes and comfortable wearing due to their emphasis on manageability and comfort. This survey was limited to the Gyeonggi and Inchon area and leaves room for future studies.

Purpose: This study was conducted to describe the perception of parental sex role held by university students and to examine differences in perception of parental sex role according to student characteristics. Method: The participants were 336 university students in Gangreung city. The instrument of parental sex role was developed by the researcher and consisted of 3 subcategories; general parent role, parental sex role as a father and parental sex role as a mother. Results: The most positive item of parental sex role as a father is 'the Father's role is teaching about the value of society'. The most positive item of parental sex role as a mother is 'the Mother's role is to be a counselor or friend'. There were significant differences in perception of a father's role according to sex, type of college, fathers who lived with student during childhood, the relationship with the parent, the plan of marriage & having a child, responsibility of childrearing, and the need for education for the parental role. There were significant differences in perception of the mother's role according to sex, grade, type of college, birth order, type of family, persons who lived with student during childhood, the relationship with the parent, plan of marriage & having a child, responsibility of child-rearing, and the need for education for the parental role. Conclusion: The parental sex role changes overtime. Thus, it is important to identify university student's perception of parental sex roles as pre-parent preparation for parenting.

Objectives : The purpose of this study was to pursue an efficient operating plan by surveying the cognition and demand level for major deepening course. Methods : Questionnaire survey was carried out targeting 135 dental hygienists who work in Cheonan and neighboring region. The collected data was performed frequency & percentage, T-test and ANOVA analysis. Results : 1. As for dental hygienists' acquiring academic degree, 77.0% of them responded to have interest. As for a desired route of acquiring academic degree, the major deepening course or Credit Bank System was the highest with 62.2%. 2. As a result of surveying cognition on major deepening course, 73.3% responded to know. A route of having come to know was the largest in senior or friend with 34.8%. Necessity of major deepening course was responded to be necessary with 89.7%. 89.1% of them clarified to have intention of acquiring. 3. The curricular subject, which is desired to be learnt for a plan of operating major deepening course, was the highest in the major field with 63.0%. 4. As a result of comparing an interest, necessity, and intention of acquisition on major deepening course depending on general characteristics, the statistically significant difference wasn't shown. Conclusions : These results suggest that major deepening of course through active public should be aware that many dental hygienists will be subject to a variety of programs and development of clinical course and a practical hands-on education is expected to be strengthened.

Objectives: Adolescence involves a number of developmental processes, as well as unique psychological characteristics and behaviors. An increased rate of internet and game addictions, school violence, and suicide may either represent aspects of adolescence or a psychopathological phenomenon. There is an urgent need to develop software programs that can prevent and resolve adolescent behavioral problems. We applied the mentalization theory to interpret and find solutions for problems faced by adolescent characters in literature. Methods: In Joan Rowling's novel "Casual Vacancy," Sukhvinder is a girl with problems representative of those encountered by modern adolescents; she is a victim of bullying and engages in self-mutilation. We targeted her problematic behaviors as representative of a prementalized state. Results: Born into an upper-class English family with Pakistani origins, Sukhvinder, unlike her siblings, fails her parents' expectations. Whenever she faces a psychological crisis, she regresses into the teleological mode (the most primitive pre-mentalization stage) and regains her sense of self by cutting herself. After her friend's suicide, however, she begins to communicate with her parents and moves toward mentalization. Conclusion: By analyzing Sukhvinder's behavior, we assessed patterns of attachment, empathy, and mentalization, and identified corrective approaches for problematic behaviors. We believe that the presented interpretation may serve as a foundation for the development of models for understanding adolescent deviant behaviors.

In the past, radars have been classified into fire control radars, detection radars, tracking radars, and image acquisition radars according to the characteristics of the mission. However, multi-function radars perform various tasks within a single system, such as target detection, tracking, identification friend or foe, jammer detection and response. Therefore, efficient resource management is essential to operate multi-function radars with limited resources. In particular, the target threat for tracking the detected target and the method of selecting the tracking cycle based on this is an important issue. If focus on tracking a threat target, Radar can't efficiently manage the targets detected in other areas, and if you focus on detection, tracking performance may decrease. Therefore, effective scheduling is essential. In this paper, we propose the TaP (Time and Priority) algorithm, which is a multi-functional radar scheduling scheme, and a software design method to construct it.
