The purpose of this study was to investigate the percent of body fat. fatness indices. and relationship between the percent body fat and dietary factors among the female middle school athletes. Hights, weights, an percent body fats of 17 soccer player. 10swimmer, and 5 rhythmic gymnast were measured. Dietary data were collected by questionnaires. The results of this study are summarized as follows. 1. Average body fat measured by infrared interactance method was 23.8$\pm$4.9% and BMI body fat was 20.3$\pm$2.6% Fatness indices such as BMI was 18.8$\pm$2.1 Rohrer index 119.4$\pm$11.8 percentage of ideal weight 90.4$\pm$9.2 and RBW 29.7$\pm$4.1. 2. Soccer player, swimmer, and rhythmic gymnast showed significant differences in percent body fat and fatness indices. ryhthmic gymnasts were smaller and lighter. 3. Most athletes were interested in diet and nutrition. and wanted to learn more about nutrition. Middle school female athletes ranked parents first or second for nutrition information. followed by managers$.$coaches$.$trainers. 4. Nutrition knowledge test score was 4.7 point out of possible 10, which is rather low, and showed significant difference in 3 kinds of players. 5. The quantities of food eaten in breakfast. lunch dinner and snack were significantly different among soccer player. swimmer. and rhythmic gymnast. In preference score of food groups, only beverage score was significantly different and of cooking methods. roasting and steaming were significantly different among the soccer player. swimmer. and rhythmic gymnast. 6. When subjects were divided into 3 groups on the basis of % infrared body fat, subjects with the highest body fat showed the tendency to eat more than others(non-sig). In the preference score of food groups. only fish showed significant difference among the groups. There were no significant differences between body fat and preference of various cooking method.

This paper examines several articulatory properties of /k/, known as a trigger of place assimilation as well as the object of post-obstruent tensing (/tk/), in comparison to non-assimilating controls (/kk/ and /kt/). Using EMMA, tongue body articulation in the place assimilation context robustly shows greater spatio-temporal articulation and lower jaw position. Results showed several characteristics. Firstly, constriction duration of the tongue body gesture in C2 of the assimilation context (/tk/) was longer than non-assimilating controls (/kk/ and /kt/). Secondly, constriction maxima also demonstrated greater constriction in the /tk/ sequences than in the control /kk/, but similar values with the control /kt/. In particular, results showed a significant relationship between the two variables - the longer the constriction duration, the greater the constriction degree. Lastly, jaw height was lower for the assimilating context /tk/, intermediate for the control /kk/, and higher for the control /kt/. Results suggest that speakers have lexical knowledge of place assimilation, producing a greater tongue body gesture in the spatio-temporal domains with lower jaw height as an indication of anticipating reduction of C1 in /tk/ sequences.

There are a lot of dental emergency situation. Especially on disabled or pediatric patient with negative behavior, accidental aspiration or ingestion of foreign body (ex: dental instrument) is one of the common accidents in dental procedure. Dentists and dental hygienists must have knowledge about the precaution and be ready to deal with foreign body aspiration during dental treatment, especially on the disabled. This is a case of an accident during the dental treatment of 14-year-old female patient with cerebral palsy. During scaling, prolonged retained primary tooth which had resorbed roots was fell into left bronchi. So we tried to remove the crown by endotracheal approach. Most ingested foreign bodies pass through the gastrointestinal tract spontaneously, but some of them need endoscopic or surgical removal. Moreover aspiration into broncho-trachea can be more serious events and must be treated as emergency situation.

This study was designed to investigate the relationship between body mass index and food habits of college students. For this purpose, 358 students of Kangweon University were asked to fill out the questionnaires for food habits and weight control. The results are summarized as follows ; The rate of underweight, normal and obese was 16.5, 65.1, 18.4%, respectively. Food habits score of obese females were lower than normal or underweight females. Male subjects did not show significantly different scores among the three groups. Female obese subjects have lower scores than the other groups on the eating time, seaweed intake, protein intake and vegetable intake. Male obese subjects have nutritious meals and more eating time than normal and underweight males. College students are the early stage of adult life and their food habits, food behaviors and life style will continue in later life. Therefore, college students need more nutritional knowledge, positive dietary attitudes and modified life styles to prevent and treat obesity.

This paper attempts to analyze the trend of research methods in Korean social welfare research and discuss utilities of qualitative research methods in broadening and deepening social welfare knowledge body in Korea. First, this paper examines research methods of 538 research articles published in Korean Journal of Social Welfare from the volume one in 1979 to the volume 51 in 2002. It has the following results: (1) non-empirical research articles were dominant in the 1980s; (2) empirical research articles have been dominant since the middle of the 1990s; and (3) research articles utilizing qualitative methods have appeared rarely since the end of the 1990s. Second, this paper examines the characteristics and the types(phenomenology, grounded theory, ethno-graphic approach, narrative inquiry etc.) of qualitative research methods. Third, this paper discusses (1) fitness between practice in social welfare discipline and qualitative research methods and (2) utilities of qualitative research methods in broadening and deepening knowledge body of Korean social welfare. In discussing the fitness, this paper focuses that qualitative research methods fits with the needs of social welfare discipline regarding broadening and deepening our understandings about social phenomena related to practice, and (2) qualitative research methods fits the needs of social welfare discipline regarding developing endogenous knowledge. In discussing the utilities, this paper focuses that qualitative research methods can be more properly utilized for social welfare research because there are coincidences in basic assumptions and perspectives of both qualitative research methods and social welfare practice. Finally, this paper highlights that 'many ways of knowing' exist in social science and it should be considered more sincerely in the arena of Korean social welfare research in order to more solidly develop the knowledge body of social welfare and practice in Korea.

It is important to provide the opportunity and means to change body posture frequently during the work period. Maintaining a given posture, even if it appears comfortable in the beginning, becomes stressful as time goes on. In order to design most products some knowledge of the dimensions of the human body is required. Data concerning human body dimensions are referred to as anthropometric data. Anthropometric data are used to establish many product dimensions such as the heights of work surfaces, minimum size for access openings, spacing between controls, mounting angles for displays, distance between user and controls, and so forth. The usual procedure is to design to accommodate 90% of the population of anticipated product users. In sosme instances it is necessary to provide a method for adjusting because it allows users to alter the produst's dimensions to meet their individual needs. When the user makes the proper adjustments, the product will be easier to use (e.g., the seat and rearview mirror adjustment mechanisms on automobiles) or more comfortable (e.g., office chairs and stereo headphones).

The major challenge in wireless body area networks (WBAN) is setting up a protected communication between data consumers and a body area network controller while meeting the security and privacy requirements. This paper proposes efficient and secure data communication in WBANs using a Twofish symmetric algorithm and ciphertext-policy attribute-based encryption with constant size ciphertext; in addition, the proposed scheme incorporates policy updating to update access policies. To the best of the author's knowledge, policy updating in WBAN has not been studied in earlier works. The proposed scheme is evaluated in terms of message size, energy consumption, and computation cost, and the results are compared with those of existing schemes. The result shows that the proposed method can achieve higher efficiency than conventional methods.

BACKGROUND/OBJECTIVES: Childhood obesity has increased in recent decades in Korea. This study was designed to examine differences in the eating habits, physical activity (PA), nutrition knowledge, and self-efficacy of children by obesity status. SUBJECTS/METHODS: Subjects were 5th-grade children from 70 elementary schools in 17 cities nationwide. Two-stage stratified cluster sampling was employed. Survey questionnaire included items related to general characteristics, eating habits, PA, nutrition knowledge and self-efficacy. Excluding incomplete responses, 3,531 data were analyzed using SPSS. Subjects were categorized into overweight obesity (OW) and normal weight (NW) groups based on body mass index percentiles for age by sex. RESULTS: A total of 21.5% of subjects was overweight or obese. There were significant differences in gender, perceived stress, perception of body shape, body satisfaction, and interest in weight control between the OW and NW groups (P < 0.001). With respect to eating habits, the OW group ate breakfast (P < 0.05) and snacks (P < 0.01) less frequently, ate bigger meals (P < 0.001), and demonstrated less desirable behaviors during meals (P < 0.05 in boys) compared to the NW group. The OW group participated in less PA than the NW group, especially boys. OW boys spent less time walking during weekdays (P < 0.05) or the weekend (P < 0.001), spent more time being sedentary during weekdays or the weekend (P < 0.001), and exercised a fewer number of days (P < 0.01). For girls, the OW group spent more time being sedentary during the weekend (P < 0.01) and exercised a fewer number of days by walking or bicycle riding (P < 0.05) than the NW group. Nutrition knowledge was not significantly different between the OW and NW groups. Self-efficacy (P < 0.01 in boys), especially PA self-efficacy (P < 0.01), was significantly lower in the OW than NW group. CONCLUSIONS: This study revealed differences in eating habits, PA, and self-efficacy between OW and NW children. Obesity management programs for children need to focus on increasing self-efficacy, modifying eating habits, and increasing PA.

The role and function of nursing care nowadays, tend to acquire sophisicated technology because specialization has expended due to increase of the medical population and the improvement of national health standards. To implement nursing care independently as a professional nurse, the apprehension of specific knowledge and skill should be acquired during basic nursing education. So it is important for nursing education not only to include theory and actual techniques, but also to strengthen the practical training in the actual clinical setting. This study was carried out with the following objectives; 1. To survey the detailed content and frequency of actual nursing students display during their clinical training. 2. To investigate the detailed content and frequency of actual nursing behavior which students display in each clinical a area. 3. To identify the motive for selection of nursing as their major and to determine the degree of self confidence, extent of knowledge and recognition of nursing responsibility. 4. To observe the relationship between actual nursing behavior and each of the following; 1) Motive for selecting nursing as a major 2) Self confidence 3) Knowledge of nursing care 4) Recognition of nursing responsibility The conclusions of this study were as follows; 1. Among the detailed nursing behavior which junior nursing college students carry out in clinical training; taking respiration's showed the highest frequency, and taking body temperatures, blood pressures, and pulses and making beds were next in frequency in this order. 2. In detailed nursing behaviors according to clinical area; taking vital signs showed the highest frequency in the emergency room, pediatric ward, orthopedic ward, general surgical ward and internal medicine ward. However, in the operating room, assisting with endotracheal tube insertion and sterile techniques were showen to have the highest frequencies. In nursery, umbilical cord care and the measurement of body weight were the highest in frequency In neurosurgical ward, the measurement of vital signs, changing position and tracheostomy care were the highest in frequency. In obstetric and gynecological ward and in the delivery room, checking duration, intensity and frequency of contractions was the highest in frequency. 3. In regard to the motive for majoring in nursing, the aptitude and interest of the student had the highest percentage(32.86%), and self-confidence in nursing activities (M=3.36), knowledge in nursing activities.(M=3. 09), and the recognition of the nursing activity (M= 3.76) wire in the middle range. 4. When the detailed nursing behaviors were compared with motive, self confidence, knowledge and recognition, it was found that when the nursing behavior was difficult and regarding much endeavor although the motive was high, the frequency of the nursing behavior was rather low. But in the cases in which there was much self confidence and a high level of skill was required, nursing behavior was carried more frequently. When there was muck self confidence and skill was not required, the frequency of nursing behavior was rather low. In the cases of a high level of knowledge, the frequency of nursing behavior was low and when recognition for nursing behavior was given the frequency of nursing behavior was low.
