In this study, 150 previous studies of young children's challenging behavior, conducted over the past 10 years, from 2003 to 2012, were selected. These studies were in relation to young children both with and without disabilities, and they were thus used for the purposes of comparative analysis. The major findings are as follows. First, research on challenging behavior not only of young children with disabilities but also of those without disabilities has been an increasing trend from 2008. While most studies of those without disabilities were based on observations by parents or teachers using a variety of tools, studies regarding those with disabilities mainly used single-subject research methods using an operational definition. Second, the bulk of the studies of young children without disabilities were focused on interaction between various children's internal variables and a variety of parent-related variables related to the occurrence of challenging behavior. In comparison, studies of young children with disabilities were focused excessively on direct intervention after the occurrence of problems. Regarding those without disabilities, the interaction between children's temperament, internal variables, and their mothers' parenting behavior, external variables were the main areas of interest for these researchers. There is clearly a growing need for more active research aimed at the prevention of challenging behavior. Challenging behavior in early childhood has an influence not only on each child's present and future academic achievement levels and their quality of life but also on the quality of instruction in classroom available to all children.

Hanseo University's Tae-an Airfield was opened in July, 2005 for aeronautical education such as aircraft flight, air traffic control, avionics, etc., and will play an important part as a base for local economic and industrial developments. On the contrary, the aircraft noise from the airfield will give an impact against the vicinity of the airfield and become a big issue which the airfield authority has to solve. The aim of this study is to analyse the aircraft noise contour in vicinity of the airfield and to make understand the people around the airfield how much the aircraft noise will have an effect on. For the prediction of the aircraft noise in the local area, this study showed the method to assess the aircraft noise in the developed countries for aviation, and the result to compute WECPNL by INM 6.1 after encoding the various data including environmental input data, tract, and profile. The major results of the study can be summarized as follows ; While the area with influence contour of noise from 75 to 80 WECPNL is 0.555$km^2$, the area from 80 to 85 is 0.343$km^2$, and the area with influence contour of noise over 85 WECPNL is 0.163$km^2$. In addition, there are 4 houses in the contour over 85 WECPNL and the inhabitants(10 people) in this area will have effect from the noise. Therefore Tae-an airfeild authority is preparing the noise-prevention method or noise abatement program. Finally, according to the noise contour, it is one of the best way of decreasing the effect of aircraft noise that 33 runway is assigned as calm-wind runway because there is no resident in the area around 15 threshold.

As the elderly population has increased in the advanced countries, food intake, relationship of nutrient intake and disease has become major problem in the aged. To investigate the dietary behaviors and the preference of food of the elderly for developing meal planning, the study was conducted through survey questionnaires including 24-hr dietary recall, dietary behaviors, food preference and frequency of food intake to 352 elderly (104 male and 248 female) who were more than 60 years old and living in Seoul. Most of subjects ate three meals regulary and the most preferred taste was sweet and the less preferred taste was sour. Dietary behaviors according to educational level were shown that the skipping meal time and duration time of one meal were significant difference in educational level. Most of the elderly subjects like kimchi and soybean paste soup. The more educated elderly were preferred milk. The reason of dislike of milk was bad flavor and diarrhea. Most of them who graduated from university and high school selected fishes because of good for health primary, otherwise no educated, elementary school and middle school graduated elderly selected vegetables primary. Meats, fishes, seaweeds, mushrooms, fruits, milk and milk products, eggs and vegetables intakes of total elderly subjects were significantly positively related to educational level. With respect to milk and milk products intakes, cheese, yogurt (curd) and milk intake of elderly was significantly negatively related to age. Therefore education for developing desirable dietary behaviors and improving the meal patterns should be in forced to elderly, especially who had poor educational background in order to manage the meal planning and to care for their health in the later life.

In Korea, changes in children's diet patterns accelerate their physical growth and development: frequent snacking has been presumed to be a major cause of increasing dental caries. The present study attempts to clarify the relationship between the physical development of growing children and their tooth decay. For this purpose, 632 six-grade children in 4 elementary school located in Urban(Seoul) and Rural(Po-gok, Yang-In) were classified into three groups based on the Weight Length Index(WLI), known to reflect the nutritional conditions of school-age children, and the relationship was analyzed between each group and the variables considered to be related with dental caries. The result is as follows: The average weight and height of the male is $44.88{\pm}10.89$ kg, $148.49{\pm}7.33$ cm and female is $43.35{\pm}9.60$ kg, $149.23{\pm}6.73$ cm, respectively, which are in the similar level with the Korean Physical Standard. The classification of the children by the WLI reveals a relatively high distribution of over-weighted child ren - 212 persons, 335% of the entire population. The DMFT Index was a little high in the rural area(3.15 teeth in urban and 3.31, in rural). Among the groups of children classified by the WLI, the over-weight group have the highest DMFT index(3.69 teeth). The relationship between the frequency of taking in basic nutrients and the DMFT index is also found: the relationship is not evident in case of the foods containing rich calcium, protein, as well as fruits and vegetables. But, in the protein-rich food, higher frequency of its intake means significantly lower DMFT index in the normal-weight group of the urban children. In case of carbohydrate, higher frequency of its intake means significantly higher DMFT index in all the groups of the rural children. The DMFT index has some correlations with the relevant variables: the index has a positive correlation with the frequency of snacking, and a negative correlation with the economic status. That is, the higher the frequency of snacking is, and the lower the economic status is, the higher the DMFT index may be. In the logistic multiple regression analysis conducted with the presence of DMFT as a dependent variable, only the frequency of tooth brushing is turned to be a variable affecting the presence of either decayed, missing, or filled teeth. Based on the above result, the variables affecting the DMFT index are a time spent on eating, frequency of intake of protein and carbohydrate for a week, frequency of snacking, regular dental check-ups, preventive behaviors for oral health(fluoride gargling, tooth brusing after each meal, proper tooth brushing method). These variables have a relationship with the DMFT index, but the degree is somewhat different between the groups classified either by the region or by the WLI. Therefore, appropriate nutrition management should be conducted according to the individual's nutritional conditions when the services like nutritional education are provided based on the closely-examined characteristics of each target group. And, at the same time, oral health education should be strengthened, and its importance should also be emphasized so that people can pay attention to their own oral health.

The purpose of this study is to reduce the probability of occurrence of electric fires as a preemptive preventive measure, and to strengthen the capability of preventing electric fires by strengthening the cooperative function between electric fire-related departments and establishing a cooperative system. In this study, the general aspects of electric fires were identified by reviewing the literature such as ignition mechanisms of electric fires. And the major electrical fires that occurred in the last 10 years were classified into ignition factors (short circuit, overload/overcurrent, and earth leakage/ground fault) and ignition sources (wiring/wiring appliances, electrical equipment/household appliances). And the 4M technique was used to analyze the potential causes of ignition at the fire site and to suggest preventive measures. In the case In this study, out of 48 electrical fires in the past 10 years, 16 short-circuit fires, 3 overload/overcurrent fires, 3 short-circuit and earth fault fires, 16 fires in wiring/wiring appliances, and 10 fires in electrical equipment/home appliances classified as cases. And prevention measures were presented in terms of human, machine, media, and management by using the 4M technique. For the preemptive prevention of electric fires, strengthening the compulsory electrical safety inspection and making it mandatory to report when new or expanding electric facilities, charging a fee for electric safety inspection for detached houses and granting benefits subject to inspection completion, improvement of the electric safety voluntary inspection table and safety indications; It was suggested as a policy to organize and operate electrical safety inspection personnel in a two-person team (mixed), establish a close work cooperation system with related organizations, and strengthen electrical safety education and publicity.

Reacently one the main issues has been to develop useful strategies to improve hospital services for patients in the health care delivery system in our rapidly changing society. This study has focused on exploring the perceptions that the clinical nurses have concerning who they are and what they are going to become in the days ahead as medical care reaches a new stage of advancement centered around the patient and hospital services. This study in also based upon the premise that the role of the clinical nurse practitioner. is central to the progress of any patient centered nursing program. This study was carried out by the members of the academic committee of Seoul Branch of Korean Nurses Association from January 1995 to February 1995. The interview method was a semi-structured questionnaire used to collect data from 25 staff nurses who were working more than 3 years at 3 different university hospitals in Seoul. The 6 interviews were selected from each hospital and they were trained for the interviewing techniques. The data were analysed qualitatively and 10 elements of the nurse's responsibilities classified such as caring for the patients (which includes specific medical care as well as general); assessing; diagnosing; coordinating with other health personnel; careful listening; teaching and the patient guiding; administering the prescriptions; giving information and counseling the patient; ward management. Although the premise of this study was based on a wholistic concept, the overall behavioral aspects of hospital clinical nursing were the major thrust of the questionnaire. Broad philosophical questions regarding the nature of nursing need to be further explored. The data gathered for this questionnaire should be useful as a reenforcement tool in educating nursing students as well as in continuing education for clinical nurses. For the future, another study should be done to determine the nursing/patient relationship.

To reinterpret the meaning of fluvial terraces in the Quaternary researches, the concepts and geomorphic properties of fluvial terraces are reviewed. Fluvial terraces are the alluvial landform that was once river channel or floodplain by paleochannel flowed in elevated areas from the current river by active incision of rivers due to the climatic changes and/or uplifts. As fluvial terraces are the remnants of alluviums after incisions of rivers, the major factors influencing on the incisions are the falling of erosion base, increase of river discharge and distinct geomorphic phenomenon of river. While it is generally known that fluvial terraces deposits in the upper or middle reaches of large rivers were formed during glacial periods, the deposits may be formed at the various periods due to the diverse natural environments and geomorphic properties of specific rivers, because there have been numerous cases that the ages of fluvial terraces in the upper or middle reaches of large rivers in Korea and China can be correlated to the interglacial periods.
