The purpose of this study was to investigate the elementary school dietitian's status and recognition of nutrition education (NE) in Incheon. A cross-sectional study was carried out using a self-administered questionnaire and subjects were 100 elementary school dietitians. The results are as follows. As for training in NE, $61.2\%$ of the dietitians attended training in NE. After training in NE, $86.5\%$ of the dietitians who attended training in NE were more concerned about NE. Also $59.5\%$ of the dietitians gave students NE and most of them did as a weekly printout 2-4 times per month. There was a significant difference in experience of NE for teachers between subgroups by experience of training in NE; while $48.1\%$ of the dietitians with training in NE gave teachers NE, $20.0\%$ of the dietitians without training in NE gave teachers NE. The main reason for not giving NE was too much work load and low concern of school administration. Also $96.4\%$ of the dietitians answered that NE is necessary in elementary school and the main reason for being necessary was correction of unbalanced diet and good table manner, As for proper time to start NE for children, $51.8\%$ of dietitians answered 'kindergarten' and $45.8\%$ of them answered 'lower grade of elementary school'. As for effective type for NE, $59.5\%$ of the dietitians answered 'NE as a part of other subject' and $23.8\%$ of them answered 'NE as a separate subject'. Also $79.5\%$ of the dietitians answered 'teacher' as the suitable person for NE. Most of the dietitians recognized menu formation as the ideal major work load and office work as the most time-consuming work load. As to job satisfaction, most of them were dissatisfied with office work and NE. Therefore, it is nationally supported for elementary school students' health and well-being that school dietitians as NE specialists give NE with minimizing their office work and developing a standardized NE program.

Parish nursing is a community health nursing role developed in 1983 by Lutheran chaplain Granger Westberg. An increasing emphasis on holistic care, personal reseponsibility for a healthy lifestyle, and changes in healthcare delivery systems have undoubtedly facilitated the establishment and nurturance of an innovative nursing role in the community. Parish nurses are functioning in a variety of church congregations of various denominations. The parish nurse is a educator, a personal health counselor, a coordinator of volunteers. The parish nurses helps people relate to the complexed medical care system and assists people to integrate faith and health. The autors conducted a study on pastor's expectations from parish nurses. Results of this study will be useful to those instrumental in planning, initiating, supporting, and evaluating a parish nurses program The research was done on 130 pastors in Taegue and Kyong Sang Buck Do, of various ages ranging from their 20's to 60's: and pastoring churches of various sizes, ranging from under 100 to over 300 members. 94.6% agreed that they needed a parish nurse on their staff; and 86.2% said they wanted to start a parish nurse program in their churches if certain basic conditions were met. The pastors responded that some would hire the nurses on a full-time basis(22.3%), a part -time basis (37.7%) or use volunteer nurses (40%). The pastors said they would expect the following from a parish nurse: health counselling (80.0%) regular health check-ups (78.5%) health care for the elderly (78.5%) health information and education (72.3%) hospice care (72.3%) visiting sick church members at home (69.2%) arranging and training volunteers to help the seek (59.2%) health care for expectant mothers (50.0%) introducing and taking people to health care facilities (46.2%) The pastors were surveyed about specific areas of health education they would want the parish nurse to teach(for example, high blood pressure and heart disease prevention and management(76.2%) ; stress management(74.6%); and diabetes prevention and management(73.8%). The pastors were surveyed about specific areas of health counselling they would expect the parish nurse to do (for example, drug abuse, (73.1), alcohol abuse(64.6%), marriage conflict(60.0%), recovery after the loss of a loved one(56.9%), and women's conflict with parents-in-law(53.8%). The pastors were surveyed about types of things they would want included in regular health check-ups, what they would want a parish nurse to do on home visits, and what they would want included in home care for the elderly. They were also surveyed on what kind of spiritual care they would like parish nurses to give. Most (90.7%) wanted their parish, parishioners to be involved in the parish nurses program as volunteers, and in a variety of ways(such as visiting sick in their homes(68.5%) and helping with housework(63.1%) and taking sick people to health facilities(60%). Parish nurses role, activities, and boundaries of practice should be continuously monitored and refined and a 'case manager' should be conceptualized as an additional or all-encompassing role. An initial parish / community needs and readiness assessment should be done prior to establishing a program to detemine if the congregation is ready, willing, and able to support such a position for at least a 2 to 3 year period.

This study selected five observational stations in the normal direction of Jinu-do(island) shoreline and observed water temperature, electrical conductivity and pressure from March, 2012 to January, 2013(about 11 months) and attempted to see the variation characteristics of ground watertable. This study wants to know : 1) External environment force factors(tide, climate, wave etc.) affecting ground watertable variation through time series and correlation analysis. 2) Spatial variations of ground watertable and electrical conductivity change by storm event. First, we found that the station at the intertidal zone was strongly affected by wave and tide level and the stations at sand dune and vegetation zone was affected by precipitation and tide level through time series data and correlation analysis. Second, during the storm event, we found that ground watertable and electrical conductivity are stabilized at the start line of sand dune and vegetation zone and transition zone between freshwater layer and seawater layer exists in the experiment area and is about 50~70 m from coastline of the south side of Jinu-do(island).

Rice plants were exposed to $I_2$ vapor for 80 min at different growth stages in an exposure box to investigate the parameters concerning direct plant contamination. Deposition velocity $(m\;s^{-1})$ of the $I_2$ vapor for the straws was in the range of $1.4{\times}10^{-5}-1.3{\times}10^{-4}$ depending on the exposure time, being comparatively low during the earlier part of the plant growth. Ear deposition velocity was in the range of $2.5{\times}10^{-5}-6.7{\times}10^{-5}$. Whole-plant deposition velocity was in the range of $1.4{\times}10^{-5}-1.8{\times}10^{-4}$ with the highest from the exposure performed on Aug. 18 (7 d after the start of heading). The time-dependent variation generally decreased when the deposition velocity was normalized to the biomass density No noteworthy tendency in the deposition velocity was observed with regard to the temperature, sunlight and humidity. Translocation factor for the hulled seeds was $3.3{\times}10^{-5}-4.7{\times}10^{-4}$ with the highest from the Aug. 23 exposure. It was found that a leaf deposition even before the ear emergence resulted in a considerable seed translocation.

The purpose of this study was to compare the sleep characteristics between the prone and the supine position in healthy newborns. The 48 newborns were observed in the prone position and the supine position respectively on the 2nd day after birth. The data were collected from January to May, 1999. The state of a newborn was classified and categorized to 6 states (deep sleep. light sleep, drowsy, quiet alert, active alert, crying) by Barnard. The movements of eyes, face and extremities, pulse and arterial oxygen were observed and recorded continuously from the start of sleep after feeding until the time of being woken for the next feeding by a trained nurse The data was analyzed by using paired t-test. The results of this study were as follows; 1. There was no significant difference in the length of sleeping time between the prone and the supine position. 2. There was no significant difference in the length and frequencies of each states(deep sleep, light sleep, drowsy, quiet alert, active alert, crying) between the prone and the supine position But the frequency of light sleep in the supine position was significantly higher than that of the prone position. 3 There was no significant difference In the numbers or eyes movements between the prone and the supine sleep position. But the amount of facial and extremity movement in the supine position was significantly higher than those in the prone position 4. There was no significant difference in the arterial oxygen content between the prone and the supine sleep position. 5. There was no significant difference in the heart rates between the prone and the supine sleep position. The above results indicated that the newborns in the prone Position moved less and slept deeper than those in the supine position. though there was no difference in the length of sleep or arterial oxygen content between the prone and the supine sleep Position. But. Nurses and mothers should consider the relationship between the sleep Position and SIDS suggested by previous researches. The infant's 'awakening' during sleep is a normal process and rather valuable because it can provide an opportunity to promote a stronger relationship between mother and baby. So, It is suggested that the supine sleep position is better than the prone sleep position for infants.

Back-door-listing can be viewed both as M&A and an alternative to IPO. If IPO is an access to the capital market through regulations, back-door-listing would be the way of entering the market through trading. Back-door-listing can be a better choice considering the common wisdom that regulations hinder the functioning of free market system. One would, however, prefer IPO, for the informational asymmetry isless severe in case of IPO. This paper examines if IPO is superior to back-door-listing as to the informational efficiency. The excess buy-and-hold returns of the Kosdaq back-door-listing firms are estimated over the three-year-period since the event. They are compared against the excess buy-and-hold returns of the Kosdaq IPO firms over the same period of time. The results confirm this paper's prediction that IPO should be more information-efficient. Both IPO and back-door-listing firms start with high short-term excess returns and end up with long-term under-performance. However, back-door-listing firms show more significantly damaging long-term results. Furthermore, back-door-listing firms record poorer accounting results over the research period. These results imply that there exists fad at the time of both events and, in case of back-door-listing, this fad is reinforced by the possibility of window dressing.

Objectives : The purpose of this study was to examine the relationship of the work environments of dental hygienists to their occupational diseases in a bid to provide some information on their health care, health promotion and the prevention of occupational diseases. Methods : The subjects in this study were 300 dental hygienists who worked in Seoul, urban communities involving large cities and rural areas. One-on-one interviews and a self-administered survey were implemented with their consent. Results : The findings of the study were as follows: 1. 60 percent of the dental hygienists investigated replied that they had occupation-related physical symptoms. By the length of service, the dental hygienists who worked for six to 10 years had the most symptoms. 2. Out of the occupation-related symptoms, the most prevalent symptom was a pain in the shoulders and neck(41%), followed by a pain in the lower back, a pain in the legs, a pain in the wrists and skin diseases. The most painful parts of the body were hands and arms. 3. In regard to the relationship between the general characteristics and the intensity of pain, the highest group of the dental hygienists in Seoul replied that they had a severe pain, and the lowest number of those in the large cities gave the same answer. 4. Concerning the cause of occupational diseases, 65.7 percent cited the wrong posture. 5. As to relationship between the general characteristics and regular hospital-visit experiences for the prevention of pain during work hours, many of the dental hygienists who were in their 40s and 50s visited hospitals from time to time, and many of those in their 20s never did that. 6. In regard to links between the general characteristics and an opinion on the necessity of regular education, many of the respondents from Seoul and urban regions involving large cities considered it necessary to receive education on a regular basis. By daily work hours, the highest number of those who worked for eight hours or less considered that necessary, and lots of those who worked for 11 hours didn't consent to that. The gaps between them were statistically significant(p<0.05). Conclusions : Given the findings of the study, daily work hours and length of service were two integral factors to affect the regular hospital-visit experiences and pain, and the wrong posture was identified as the most common cause of occupational diseases. To ensure the successful prevention of occupational diseases, dental hygiene students should be taught the importance of occupational disease before they start to work, and supplementary education should be provided for dental hygienists to work in the right posture.

In order to examine the seasonal variation of organic and inorganic nitrogen compounds, nitrogen compounds in compost were determined at various composting periods. Total nitrogen, organic nitrogen and biodegradable nitrogen contents in compost were almost not changed, while nonbiodegradable nitrogen contents were increased a little with the lapse of composting time. But effective contents of total nitrogen, organic nitrogen and biodegradable nitrogen were decreased with the progress of composting, while effective contents of nonbiodegradable nitrogen were not changed during composting. Ammonium nitrogen contents in compost were highest at the start of composting, and then the contents were decreased with the lapse of composting time. But after turning the contents were increased again, and thereafter the contents were decreased with the progress of composting. Nitrate contents showed a tendency adverse to ammonium nitrogen contents. Organic nitrogens in organic matter in compost were increased slowly within 9 weeks after composting, and thereafter the contents were increased rapidly to 21 weeks after composting. Total nitrogen contents determined by $F{\"{o}}rster$ Method were higher than those determined by Kjeldahl Method. Total nitrogen contents determined by Kjeldahl Method were 6% higher than biodegradable nitrogen contents determined by $F{\"{o}}rster$ Method. Loss of nitrogen in compost was highest at early periods of composting and its losses determined by Kjeldahl Method and $F{\"{o}}rster$ Method in 30 weeks after composting were 50% and 48% of total nitrogen, respectively. Highly positive correlations were observed among total nitrogen determined by Kjeldahl Method, biodegradable nitrogen determined by Kjeldahl Method, total nitrogen determined by $F{\"{o}}rster$ Method and biodegradable nitrogen determined by $F{\"{o}}rster$ Method one another.

Leakage accidents in businesses dealing with hazardous chemicals can have a great impact on the workers inside the workplace, as well as residents outside the workplace. In fact, there were cases where hazardous chemicals leaked from many businesses. As a result, the Chemicals Control Act(CCA) was enacted in 2015, the Ministry of Environment introduced an Off-site Risk Assessment(ORA). The purpose of the ORA is to secure safety from the installation of the design of the workplace facilities so that chemical accidents of hazardous chemical handling facilities do not cause human or physical damage outside the workplace. In general, the ORA qualitatively determines where a protected facility is within the scope of the accident scenario. However, elderly who belong to the sensitive group is more sensitive than the general group under the same chemical accident effect, and the extent of the damage is serious. According to data from the Korea National Statistic Office, the number of elderly people is expected to increase steadily. Therefore, a quantitative risk analysis considering the elderly is necessary as a result of a chemical accident. In this study, accident scenarios for 14 locations were set up to perform emergency evacuation due to toxic gas leakage of Cl₂(Chlorine) and HF(Hydrogen Fluoride), and the effects of exposure were analyzed based on the evacuation velocity difference of age 20s and 60s. The ALOHA(Areal Locations of Hazardous Atmospheres) program was used to calculate the concentration for assessing the effects. The time of exposure to toxic gas was calculated based on the time it took for the evacuation to run from the start point to the desired point and a methodology was devised that could be applied to the risk calculation. As a result of the study, the relative risk of the elderly, the sensitive group, needs to be determined.

Rainfall is widely recognized as a major landslide-triggering factor. Most of the latest landslides that occurred in South Korea were caused by short-duration heavy rainfall. However, the relationship between rainfall characteristics and landslide occurrence is poorly understood. To examine the effect of rainfall on landslide occurrence, cumulative rainfall(mm) and rainfall intensity(mm/hr) of serial rain and antecedent rainfall(mm) were analyzed for 18 landslide events that occurred in the southern and central regions of South Korea in June and July 2011. It was found that all of these landslides occurred by heavy rainfall for one or three days, with the rainfall intensity exceeding 30 mm/hr or with a cumulative rainfall of 200 mm. These plotted data are beyond the landslide warning criteria of Korea Forest Service and the critical line of landslide occurrence for Gyeongnam Province. It was also found that the time to landslide occurrence after rainfall start(T) was shortened with the increasing average rainfall intensity(ARI), showing an exponential-decay curve, and this relation can be expressed as "T = $94.569{\cdot}exp$($-0.068{\cdot}ARI$)($R^2$=0.64, p<0.001)". The findings in this study may provide important evidences for the landslide forecasting guidance service of Korea Forest Service as well as essential data for the establishment of non-structural measures such as a warning and evacuation system in the face of sediment disasters.
