The purpose of this study was to explore the relationships between patterns of children's requestive strategies, mother's child rearing attitude, and verbal control style. Subjects consisted of 60 5-year-old children and their mothers at preschool in Seoul. The children's requesting behavior were observed during self-selected activities in preschool. A sample of mothers of children completed the questionnaire. The result showed that the children in this study were likely to use more frequent directives of requestive strategies. Boys tended to use more indirect requestive strategies, especially demand with requestive tag. Mothers were likely to use position-oriented verbal control. Warmth and self-control of parenting and person-oriented verbal control were positively related to indirect requestive strategy of children. Rejective and controlling parenting were negatively associated with indirect requestive strategy. Position-oriented verbal control was positively related to direct requestive strategy of children.

This paper deals with the reliability analysis of a complex system, which consists of two subsystems A and B connected in series. Subsystem A has only one unit and B has two units $B_1$ and $B_2$. Marked process has been applied to model the complex system. Present reliability model incorporated two repairmen: supervisor and novice to repair the failed units. Supervisor is always there and the novice remains in vacation and is called for repair as per demand. The repair rates for supervisor and novice follow general and exponential distributions respectively and the failure time for both the subsystems follows exponential distribution. The model is analyzed under "Head of line repair discipline". By employing supplementary variable technique, Laplace transformation and Gumbel-Hougaard family of copula various transition state probabilities, reliability, availability and cost analysis have been obtained along with the steady state behaviour of the system. At the end some special cases of the system have been taken.

The purpose of this study is to compare the characteristics of the demented elderly and normal elderly over 65 staying at home in Seoul. Here, the demented elderly are defined as the aged who score under 20 on the MMSE-K testing. The subjects were 15.104 elders in home. The method is a cross-sectional study home visiting survey with questionnaires. Data analyses were conducted by using frequency, percentage, t-test and ANOVA procedures. Results are as follows: First, general characteristics such as sex, age, marriage, education, physical health, and family characteristics such as economic level and single living showed a significant variance between demented elderly and normal elderly. Second, the demented elderly showed a significantly high point of AD and IADL. Third, in contrast with normal agents, the dementia showed a high need for assistance from the care giver but followed the same pattern. In conclusion, the above findings suggested that a social support system should be developed for the demented elderly and care givers in the home.

The popularity of cosmetic procedures has increased over the past decade. Korean consumers have shown different levels of demand for the two types of cosmetic procedures (surgical and nonsurgical). This study examines the effect of appearance pressure from family, friends, and social media on the internalization and face/body satisfaction that can determine the levels of acceptance for each cosmetic procedure among young Korean females. Data was collected from 379 females in their 20s and 30s, using an online survey questionnaire. Statistical analysis were performed using SPSS 24.0 and AMOS. The results indicated that only social media pressure significantly influenced young women's internalization of attractive appearance. Internalization was negatively associated with face and body satisfaction. Face satisfaction was negatively related to the acceptance of cosmetic surgical and nonsurgical procedures; however, body satisfaction was not related to the acceptance of cosmetic surgical and nonsurgical procedures. This study highlights the significant importance of social media and its powerful impact on developing young women's body image perceptions.

Purpose: This study aims to understand the current use of and demand for assistive eating devices. These device improve the self-feeding abilities in older adults. Methods: This study used a cross-sectional study design. Descriptive statistics were performed using SPSS 22.0 for Windows. The survey participant of 282 older people(47.7%), 42 family caregivers(7.4%), and 266 staff members(44.9%). Results: Whereas most of the older adults living in their home(87.3%) did not experience difficulty while eating, older adults residing in facilities(26.4%) expressed difficulty with the process of putting food into a spoon. The difference between the two groups was statistically significant(p<.001). Wile the older adults living in home considered assistive eating devices(34.5%) as the most important requirement for self-feeding, older adults in facilities considered receiving help(39.3%) as their biggest requirement(p<.009). Older adults, family caregivers, and nursing home staff were not familiar with assistive eating devices and were not aware of their necessity. Conclusion: The study could help increase awareness about assistive eating devices and the importance of self-feeding in research and nursing educational settings. Improvement in self-feeding ability may future enhance the daily quality of life of older adults.

Purpose: The unmet medical service needs of caregivers critically influence their caring for terminal cancer patients, but not much research has been done in this regard. Thus, the purpose of this study is to investigate the association between caregivers' characteristics and their unmet medical service needs. Methods: The survey was conducted with 109 family caregivers of terminal cancer patients admitted to four hospice units. The data were collected from March 2014 through December 2014 using a structured questionnaire. The unmet medical service needs were measured using 14 items which were adopted and modified by authors. Results: Seven areas of unmet medical service needs were shown to be significant. A well-educated group showed stronger needs for counsel about cancer screening and complementary-alternative medicine and health supplement food. A never-smoked group was identified with less need for sexual dysfunction counsel. Counsel about family and personal relations was more necessary for current drinkers and current workers, and less necessary for the married. Insurance counsel was more needed for a no-religion group. Occupation counsel was less necessary for healthy patients. Financial support was less necessary for the married group. Conclusion: Based on the results, it is highly recommended to further investigate the unmet medical service needs of family caregivers for terminal cancer patients and causes of the unmet needs.

Purpose: We have studied the problems associated with increased number of ophthalmic optics students and its effects on the supply and demand of optician. Methods: We collected data from Education Statistics, a white paper of Minister for Health, Welfare and Family Affairs, academyinfo web site and University (College) web site. Results: We forecasted an estimate for supply and demand of optician using the entrance number of ophthalmic optics. Conclusions: The numbers of produced optician are in excessive supply. The excessive supply of optician can contribute towards worsening working conditions and lower job satisfaction of an optician. Therefore this can result infrequent turn over of jobs within the same field and migration into the different field of areas. To solve these problems, we will need to act with the manpower policy of government by gathering the voices of the related optician agencies. Then expansion of job domain, improvement of quality level, the improvement of the working conditions for optician can be accomplished by the unification of university system and reduction of entrance numbers for department of ophthalmic optics.

In this study, a Benthic Macroinvertebrates Family Index (BMFI) was developed using 100 indicator groups (99 families including Chironomidae with 2 phena). Families were assigned a score between 1 and 10 depending on their sensitivity to organic pollution. The BMFI was composed of the sensitivity and relative abundance of the indicator taxa. Sensitivity values of each group were generally similar to Biological Monitoring Working Party (BMWP) scores or Walley, Hawkes, Paisley, Trigg (WHPT) scores of UK, Japanese BMWP scores, and the FBI tolerance values of North America. However, sensitivity values of some taxa were significantly different from those of foreign countries, which seemed to have resulted from discrepancy in species composition, difference of taxonomic classification system, or methodological difference for estimation of sensitivity. As an annual average level, BMFI showed significant correlation with concentration of 5-day biochemical oxygen demand (BOD5) (correlation coefficient r = -0.80, n = 569 sites), total suspended solids (r = -0.68), and total phosphorus (r = -0.79). In addition, BMFI revealed strong correlation with Shannon-Weaver's species diversity (r = 0.85), Margalef's species richness (r = 0.85) and McNaughton's dominance (r = -0.84). Correlation between BMFI and water quality parameters or community indices such as species diversity did not show significant difference compared to that of species-level indices such as BMI (Benthic Macroinvertebrates Index). This means that BMFI is a more useful indicator in terms of easy identification of organisms. BMFI was used to assess the environmental status of 3,017 sites of Stream Ecosystem Survey conducted by the Korean Ministry of Environment between 2016 and 2018. As a result, about half of all sites appeared to be in good condition, and a quarter in poor condition.
