Purpose : Diabetes mellitus (DM) is known as one of the common causes of secondary enuresis in children. However, enuresis in diabetic children is overlooked only as a symptom of polyuria due to hyperglycemia. We evaluated the prevalence of nocturnal enuresis in children with diabetes mellitus in this paper. Methods : Among children with diabetes in three hospitals in Daegu area, 117 agreed to 'Tele research by means of a questionnaire'. Results : Diabetic patients were divided into two groups: Nocturnal enuresis and nonnocturnal enuresis group. thirty-two of 117 (27.0%) patients were in enuresis group, with more daytime urination than non-nocturnal enuresis group ($4.2{\pm}1.6/3.6{\pm}1.2$ times, P=0.016). HbA1c at diagnosis was $12.0{\pm}2.3%/12.0{\pm}2.5%$, and at follow-up $9.3{\pm}2.3%/8.3{\pm}2.3%$ (P =0.042). Insulin was administered at $1.1{\pm}0.5/1.1{\pm}0.4$ units/kg/day. Ten children of enuresis (31.2%) group were monosymptomatic (MNE) and 22 (68.8%) children were non-monosymptomatic enuresis (non-MNE). Fourteen (43.8%) of enuresis group had persistent symptoms, with 5 MNE and 9 non-MNE each. HbA1c at diagnosis was $11.1{\pm}2.5$, $12.4{\pm}2.1$, higher in non-MNE (P=0.144). Average arousal during sleep was step $3.3{\pm}1.2$, $2.5{\pm}1.0$, higher in improved enuresis group (P=0.059). Conclusion : Nocturnal enuresis among DM patients is underestimated. However, considering psychological and social effects of enuresis in children, extensive and long-term studies are needed in the future to clarify relationship between prevalence and DM control.

The republic of korea has put a great emphasis on the role of the road as widening a social infra-structural facility. Thus, vast amount of money has been invested on the road establishment. As a result, there has been fruitful outcomes in establishing the road system of the nation especially for the flat road with ease. However, in order to have more systematic and sustainable road system, we should turn our attention to more painful and high-cost regions such as mountainous districts and those are to be developed effectively. The configuration of the road is an important factor to be considered in making a decision for the road planning. Nevertheless, current road planning criterion has no such clarified and objective judging standard for figuring the configuration of the road out and, as a result, speed planning can be decided incorrectly. our research has acknowledged the necessity of estimating the configuration of the road and aimed to make it organized and sorted according to the height, slope, and the vehicle's speed. The results are as follows. First, our research made use of GIS data and classified the road into 9 different areas according to the height and the slope. Also, road classification being matched to the data of vehicle's speed, it has been shown that those characteristics of different areas have made an influence on vehicle's speed. Secondly, based on the results of the similarity between geographical classification and, vehicle's speed of sorted groups according to the height and the slope, conclusively we have classified as flat, rolling region and mountain. Since our research has made use of vehicle's speed for National Highway, it is not applicable to different functional highways. However, for the highway to be established hereafter, it can be a standard for reflection geographical characteristics.

A bacterial strain YC4963 with antifungal activity against Colletotrichum orbiculare, a causal organism of cucumber anthracnose was isolated from the rhizosphere soil of Siegesbeckia pubescens Makino in Korea. Based on physiological and biochemical characteristics and 16S ribosomal DNA sequence analysis, the bac­terial strain was identified as Pseudomonas aurantiaca. The bacteria also inhibited mycelial growth of several plant fungal pathogens such as Botrytis cinerea, Fusarium oxysporum and Rhizoctonia solani on PDA and 0.1 TSA media. The antifungal activity was found from the culture filtrate of this isolate and the active compound was quantitatively bound to XAD adsorption resin. The antibiotic compound was purified and identified as phenazine-l-carboxylic acid on the basis of combined spectral and chemical analyses data. This is the first report on the production of phenazine-l-carboxylic acid by Pseudomonas aurantiaca.

The purpose of this study is to understand Korea students' characteristics as well as to give important information of improving our education using comparative analysis of framework, test booklets, test results between PISA 2009 and NAEA 2009. PISA 2009 was administered on May of 2009 and NAEA was administered on October of same year. The summary of the results of comparing two assessment is as follows First, cut score of NAEA Advance level is bigger than the cut score of level 5, which is considered as high achievement level. The cut score of Basic level of NAEA is also higher than the level 2 of PISA, which is considered as basic achievement level. This phenomenon can show that NAEA achievement level is set little bit higher than the achievement level of PISA in mathematics domain. Second, the percentage of female students on higher level was higher than that of male students. In suburban area, the percentage of high level was small and the percentage of low level was big. Third, students of Advanced level are distributed concentrating in PISA levels 4~6, Proficient achievement level concentrating in PISA levels 3~5, Basic achievement level concentrating in PISA levels 2~4, and below basic achievement levels concentrating in below level 1 and level 3 of PISA. Fourth, the correlation between NAEA 2009 and PISA 2009 achievement scores are significantly positive. However, the correlation of subscales were low. Fifth, analysis of non-equivalent group, 11 items located in 'change and relationship', 'uncertainty', 'connection cluster' domains found to be significantly different. The percent correct showed very big difference. The analysis results presents the implication of mathematics curriculum, teaching and learning methods as well as National Assessment of Educational Achievement.

Purpose: Hospice volunteers are serving an invisible yet pivotal role in the hospice and palliative care team. This study investigated how effectively a continuing education program could enhance hospice volunteers' competency. Methods: A total of 20 hours (four hours per week) of training was provided to 30 hospice volunteers who participated in the continuing education for hospice volunteers. Efficiency of the education was analyzed with an exploratory mixed-methods design. For quantitative analysis, the volunteers were asked, before and after the training, about their attitudes towards hospice care, what makes a meaningful life, self-efficacy and satisfaction with their volunteer service. Descriptive statistics, paired t-tests, and Wilcoxon signed-rank test were performed using SPSS Window 20.0. For qualitative research, participants were placed in three groups for a focus group interview, and data were analyzed by content analysis. Results: A quantitative study result shows that this training can significantly affect hospice volunteers' attitudes and improve their self-efficacy. A qualitative study result shows that participants wanted to receive continuous education from the physical/psychosocial/spiritual aspects to better serve end-of-life patients and their family members even though they have to spare significant time for the volunteer service. They wanted to know how to take good care of patients without getting themselves injured and how to provide spiritual care. Conclusion: The continuing education program reflecting volunteers' requests is strongly needed to improve their competency. An effective continuing education requires continuous training and support in areas where hospice volunteers are interested in. A good alternative is to combine web-based and hands-on training, thereby allowing hospice volunteers freely take training that suits their interest.

The purpose of this study was to examine the influence of the disaster perception and satisfaction level of volunteer fire-fighters on the continuity of their volunteering. The 163 subjects in this study were selected from male and female volunteer fire-fighters who resided in urban and rural regions in Gangwon Province. After a this survey was conducted, the collected data were analyzed by a statistical package SPSS WIN 20.0, and frequency analysis, correlation analysis and multiple regression analysis were made. The level of statistical significance was all set at p<.05. The findings of the study were as follows: First, as for the correlation of disaster perception, satisfaction and volunteering continuity, perception of disaster countermeasures, satisfaction and the level of participation were negatively correlated with one another, and there was a positive correlation among disaster training, disaster preparation, regional disaster, the period of volunteering, and will of persistent volunteering. Second, as for perception of disaster, the volunteer fire-fighters were asked a question about disaster countermeasures, and the largest group replied they were partially aware of the countermeasures. Concerning questions about disaster training/education experience and triage, the biggest group replied they underwent the training and knew about triage on the whole. Regarding questions on the emergency contact system and emergency work schedule, they knew about the two in general. As to a question on the occurrence of human disaster, the greatest group answered that they knew about it yet not well. Third, in regard to the impact of satisfaction level on volunteering continuity, the period of volunteering was affected by needs for experience, social contact and social recognition among the subfactors of satisfaction level, and will of persistent volunteering was under the influence of social contact and achievement needs. The level of persistent volunteering was affected only by needs for experience and achievement needs.

Purpose: This study is to understand how community members perceive past life recollection and preparation for death. Methods: Using a questionnaire, we surveyed 160 adult residents of one of the districts (gu) in Seoul, Korea. Descriptive statistics were used. Results: Participants chose their 30s and 40s as the most difficult time in their lives. The most painful experience was "an illness of a family member", followed by "trouble with a spouse", and "trouble with children". As for the most difficult social experience, "sense of loss in life" was ranked the highest. Personally, the happiest time was "accomplishment of a goal", while it was "happiness through children" in family relationship and "contribution to society through my career" in social life. As for the most regrettable experience, personally "having lived without purpose" was the highest, "not meeting my parents' expectation more" in family relationship; "not providing sufficient education" in relationship with children; "not having an occupation that I wanted" in work life, and "lack of social skills" in social life. More than 87% of the surveyed showed a positive attitude about the system of the do not resuscitate (DNS) order. For a situation where participants were supposed to have an incurable disease, "I want to be notified of the true condition" and "I want to write a will and advanced directives" ranked high, receiving more than 3.1 points out of 4. Conclusion: These results demonstrate the need for death education to provide people with an opportunity to accept their regrettable experiences in the past as part of their life. Also, this study suggests the importance of writing advanced directives for people to prepare for "death with dignity" how it can help their decision to be better respected.

This study was conducted by using the ICP-AES (Inductively Coupled Plasma - Atomic Emission Spectrometry) to investigate the seasonal changes of copper and manganese content in the raw bovine milk. From July 2003 to June 2004, the milk samples were collected from the two geographical locations, Chungcheong-do and Jeolla-do, in Korean peninsula. Copper (Cu) content was determined in the range of min. 10.10 to max. 21.00 ${\mu}g$/100 mL (13.79 ${\mu}g$/100 mL) in spring, 5.06 to 15.41 (10.17) in summer, 5.04 to 19.70 (10.70) in autumn and 6.96 to 17.90 (12.11) in winter. For manganese (Mn), 3.00 to 8.30 (4.87) in spring, 2.30 to 6.44 (3.75) in summer, 2.81 to 6.04 (3.82) in autumn and 2.25 to 9.02 (4.48) in winter. Those data have shown that levels of copper and manganese was relatively constant but higher in Spring than other seasons, suggesting that the levels were not affected by seasons and different locations in Korea.

Korean Economy has been developed by the Korean Government's Support for the Large-sized Firms. This Government Policy causes the Polarization between Large-sized and Micro-sized Firms Aggravated. Micro-sized Firms are distributed over the Whole Industry Area, and can also cause the Economic Crisis If They are crashed down. Therefore Government Policy for the Micro-sized Manufacturing Industry is very Important Issue. This Paper Focused on the Analysis of Current Status for the Shoes Micro Manufacturing Industry. For the Effective Analysis, This Paper uses the Statistical Data Open to the Public and also conducts the Survey for the Micro-sized Firms in Busan. Statistical Program is used for Analyzing the Collected Data and the Major Findings are as Follows. First, Shoes Industry is led by the Micro and Small & Medium sized Firms rather than the Large-sized. And the Micro-sized Firms are getting the High Rate among the Whole Shoes Industry. Busan is heavily populated Area as the Origin of Shoes Industry. Second, even though Most of the Owner of the Micro-sized Firms have the High Technology Skill Level, Worker's Aging Phenomenon gets Worse and causes the Technology Handing down to the Next Generation Difficult. Third, Because the Factory Facility of the Micro-sized Firms is Dirt and Unstable, the Modernized Manufacturing Infrastructure such as the Apartment Factory Facility is Necessary. Forth, as the Micro-sized Firms which have the Intangible Asset such as Patent is Few, the Government Policy for Encouraging the Patent Application is strongly Needed. Fifth, Entrepreneurship and Collaboration Mind between Micro-sized Firms are Lacked, so Establishment of the Cooperative Union is required. Finally, the Effort for the Systemic Planning for the Management is lacked, and the Introduction of the Management Innovation is strongly needed. The Limitation and Future Research Direction is also discussed.

Windy meteorological conditions and dried fire fuels due to higher atmospheric instability and dryness in the lower troposphere can exacerbate fire controls and result in more losses of forest resources and residential properties due to enhanced large wildland fires. Long-term (1979-2005) climatology of the Haines Index reconstructed in this study reveals that spatial patterns and intra-annual variability of the atmospheric instability and dryness in the lower troposphere affect the frequency of wildland fire incidences over the Korean Peninsula. Exponential regression models verify that daily high Haines Index and its monthly frequency has statistically significant correlations with the frequency of the wildland fire occurrences during the fire season (December-April) in South Korea. According to the climatic maps of the Haines Index created by the Geographic Information System (GIS) using the Digital Elevation Model (DEM), the lowlands below 500m from the mean sea level in the northwestern regions of the Korean Peninsula demonstrates the high frequency of the Haines Index equal to or greater than five in April and May. The annual frequency of the high Haines Index represents an increasing trend across the Korean Peninsula since the mid-1990s, particularly in Gyeongsangbuk-do and along the eastern coastal areas. The composite of synoptic weather maps at 500hPa for extreme events, in which the high Haines Index lasted for several days consecutively, illustrates that the cold low pressure system developed around the Sea of Okhotsk in the extreme event period enhances the pressure gradient and westerly wind speed over the Korean Peninsula. These results demonstrate the need for further consideration of the spatial-temporal characteristics of vertical atmospheric components, such as atmospheric instability and dryness, in the current Korean fire prediction system.
