The purposes of this study were to a) examine IC (intellectual capital) circumstance of CFMC (contract foodservice management company), b) identify the correlation between IC of CFMC, c) analyze the cause and effect of IC in the viewpoint of contractor, client, and customer. The questionnaires of IC measurement were handed out to 108 CfHCs, there composing of main office employees, foodservice managers, customers, and clients of 207 school, 38 hospital, and 86 business/industry foodservices. The statistical data analysis was completed using SPSS Win (ver 12.0) for descriptive analysis, correlation analysis, simple linear regression analysis. First, CFMCs had operational experience for an average of 8 years and 8 months, and served an average of 38,540 meals a day. Most of the respondent companies operated 'food supply/distribution($50\%$)', 'catering ($46.7\%$)', and restaurant business ($43.3\%$)' except for institutional foodservice and managed an average of 66 clients for the contract period of 2 years and 3 months. Second, there was positive correlation between $\ulcorner$sales of foodservice$\lrcorner$ and 'market ability', $\ulcorner$client satisfaction$\lrcorner$ and necessary intellectual capital for managing branch/chain foodservice office, and $\ulcorner$customer satisfaction$\lrcorner$ and $\ulcorner$renewal and development$\lrcorner$, 'market ability', 'infrastructure support for foodservice operation', 'employee satisfaction', respectively. Finally, the result of the cause and effect analysis on CFMCs, clients, and customers was positively influenced by 'client satisfaction' with 'customer satisfaction', 'infrastructure support for foodservice operation' and 'customer satisfaction' with 'employee satisfaction', and 'infrastructure support for foodservice operation'. In conclusion, if CFMCs were to perform a routine checkups by utilizing CFMC's IC measuring tool, improvements in CFMC operational capacities as well as foodservice quality can be noted. Additionally, CFMCS can satisfy their client-customer relationship by employing internal marketing thechniques for employee, a more efficient infrastructure support system, and construc tive infrastructure utilization. Therefore, CFMCs can show significant improvement in their sales and foodservice quali-ty though continuous maintenance of the client and customer satisfaction.

Purpose : This study is descriptive correlation research to provide basic materials for developing program which can give practical assistance in preventing and managing obesity through more comprehensive approaches of influential factors on obesity found in existing literatures. Methods : Data were collected from the 4th, 5th and 6th graders at 2 elementary schools in Gwangju Metropolitan City and 4 elementary schools in Jeollanamdo province using questionnaire and students' physical examination results from June 15 to July 27, 2006 and data obtained from 1,866 students were used for analysis. Data collected were analyzed with technical statistics and correlation analysis using SPSS/PC(version 12.0). Results : 1. Obesity level of elementary school students was examined as follows; 33.2% had low weight, 44.3% normal, 10.8% overweight and 11.7% obese. 14.8% of boys and 8.6% of girls, 13.5% of the 4th graders, 12.1% of the 5th graders and 9.2% of the 6th graders, and 13.7% of urban students and 9.6% of rural students were obese. 2. According to general characteristics and obesity of the subjects, there were significant differences by sex(${\chi}^2=29.55$, p= .000), grade(${\chi}^2=12.84$, p= .046), region(${\chi}^2=41.96$, p= .000) and pocket money(${\chi}^2=33.43$, p= .001). 3. As genetic factors, all variables including sibling's obesity r= .128(p= .000), mother's obesity r= .098(p= .000) and father's obesity r= .081(p= .001) had influence on children's obesity. 4. Concerning environmental factors, there was positive correlation between eating habits r=- .052(p= .02) and school record r=- .048(p= .04) and there was negative correlation between internet using time r= .050(p= .03) and conflict with parents r= .048(p= .04). 5. Self-respect as psychological factor had negative correlation as r=- .048(p= .04). Conclusion : Consequently, the influential factors on obesity of elementary school students were as follows. Obesity was higher in boys than in girls, in urban areas than in rural areas, in lower grade than in higher grade, in children with obese siblings, obese father and mother, irregular and wrong eating habits, frequent internet uses, parents in conflict and lower school record and self-respect. Therefore, since it was found that these variables were more exact causes to increase children's obesity, development of various obesity mediation programs considering these variables at home, school and society is urgently required.

The respiratory medical device is a medical device that delivers optimal oxygen or a certain amount of humidification to a patient by delivering artificial respiration to a patient through a machine when the patient has lost the ability to breathe spontaneously. These include respirators for use in chronic obstructive pulmonary disease and anesthesia or emergency situations, and positive airway pressure devices for treating sleep apnea, and as the population of COPD (chronic obstructive pulmonary disease) and elderly people worldwide surge, the market for the respiratory medical devices it is getting bigger. As the demand for both airway pressure devices, there is a problem that the ventilator standard is applied because the reference standard has not been established. Therefore, the boundaries between the items are blurred due to the purpose, intended use, and method of use overlapping similar items in a respiratory medical device. In addition, for both airway pressure devices, there is a problem that the ventilator standard is applied because the reference standard has not been established. Therefore, in this study, we propose clear classification criteria for the respiratory medical devices according to the purpose, intended use, and method of use and provide safety and performance evaluation guidelines for those items to help quality control of the medical devices. And to contribute to the rapid regulating and improvement of public health. This study investigated the safety and performance test methods through the principles of the respiratory medical device, national and international standards, domestic and international licensing status, and related literature surveys. The results of this study are derived from the safety and performance test items in the individual ventilator(ISO 80601-2-72), the International Standard for positive airway pressure device (ISO 80601-2-70), The safety and performance of humidifiers (ISO 80601-2-74) and the safety evaluation items related to home healthcare environment (IEC 60601-1-11), In addition, after reviewing the guidelines drawn up through expert consultation bodies including manufacturers and importers, certified test inspection institutions, academia, etc., the final guidelines were established through revision and supplementation. Therefore, in this study, we propose guidelines for evaluating the safety and performance of the respiratory medical device in accordance with growing technology development.

A mathematical model was developed for predicting the growth kinetics of Listeria monocytogenes in tryptic soy broth (TSB) as a function of combined effects of temperature, pH, and NaCl. The TSB containing four different concentrations of NaCl (2, 4, 5, and $10\%$) was initially adjusted to six different pH levels (pH 5, 6, 7, 8, 9, and 10) and incubated at 4, 10, 25, or 37$^{circ}C$. In all experimental variables, the primary growth curves were well fitted ($r^{2}$=0.982 to 0.998) to a Gompertz equation to obtain the lag time (LT) and specific growth rate (SGR). Surface response models were identified as appropriate secondary models for LT and SGR on the basis of coefficient determination ($r^{2}$=0.907 for LT, 0.964 for SGR), mean square error (MSE=3.389 for LT, 0.018 for SGR), bias factor ($B_{1}$B,=0.706 for LT, 0.836 for SGR), and accuracy factor ($A_{f}$=1.567 for LT, 1.213 for SGR). Therefore, the developed secondary model proved reliable predictions of the combined effect of temperature, NaCl, and pH on both LT and SGR for L. monocytogenes in TSB.

Recently, we found and analyzed vitamin $B_{12}$ in some Korean traditional plant foods which had not reported, yet. This study was to investigate vitamin $B_{12}$ intake and its dietary sources and the vitamin $B_{12}$ status in the very old elderly Koreans. We measured serum vitamin $B_{12}$ level and estimated the amounts of vitamin $B_{12}$ intake from different dietary sources in female elderly Koreans aged 85 and over who had consumed a relatively low animal traditional diet for the whole life. The average age of the subjects (n = 127) was 98.0 years (85-108 years). The assessment on energy and nutrient intake involved a one-day 24-hour recall, and serum vitamin $B_{12}$ concentration was measured by radioimmunoassay. Overall diet pattern was not different between the 85-99 yr-old group and centenarians, except centenarians were taking more dairy product. The average ratio of plant food to animal food consumption was 87.5:12.5 in weight. The average vitamin $B_{12}$ intake of our subjects was 3.2 ${\mu}g$, and 52.7% of subjects consumed under estimated average requirement, 2.0 ${\mu}g$/day. On dietary source, 67.3% of dietary vitamin $B_{12}$ was from meat, eggs and fishes and 30.6% was from plant foods, such as soybean-fermented foods, seaweeds, and kimchi. The average serum vitamin $B_{12}$ concentration was 450.5 pg/mL, and low serum vitamin $B_{12}$ (< 200 pg/mL) was found in 9.6% of subjects. Dietary vitamin $B_{12}$ intake was significantly lower in subjects with low serum vitamin $B_{12}$ (0.79 ${\mu}g$/day) than those with normal serum vitamin $B_{12}$ (3.47 ${\mu}g$/day). There were no significant difference in vitamin $B_{12}$ intake and its dietary sources and serum vitamin $B_{12}$ level between the 85-99 yr- old group and centenarians. In conclusion, several plant-origin foods including seaweed, soybean-fermented foods, and kimchi, may contribute significantly to good vitamin $B_{12}$ status in very old elderly Koreans.

The purpose of this study is to develop the first domestic professional hospice educational program. We investigated the present condition of Korean hospice education and analyzed the prerequisite need for a dedicated hospice course in the professional education process. Research was conducted between June and November 1996 for nursing professors teaching at each nursing education institute to find out how much hospice is being discussed and by whom, in which course it is being discussed, and also to find out the contents that needed to be included in the professional education process. From a total of 49 colleges(29 three year colleges, 20 four year colleges) out of 99, 162 nursing professors replied, the collection rate was 49.5%. The conclusions are as follows ; 1. The present condition of the hospice nursing education. 1) Whether hospice is included in the education program. \circled1 89.65% of 3 year colleges and 90% of 4 year colleges included hospice education in their education program. \circled2 In graduate studies three schools included hospice in their program and three schools expressed their plans to include hospice education 2) Hospice related education were commonly discussed in adult nursing(26.3%), fundamental nursing(22.8%), and psychiatric nursing(20.2%). In 3 year colleges its commonly discussed in the first and second year and in 4 year colleges it is taught in the second and third year. 3) Hospice related theory/practical education hours were averages of 6.5/7.0 hrs in 3 year colleges and 14.2/11.3 hrs in 4 year colleges. 4) The majority of professors in charge of hospice education were in the following order adult nursing, psychiatric nursing, and fundamental nursing. 5) The courses that are thought to be adequate to manage hospice related education were adult nursing(29.3%), community health nursing(21.7%) and the desired method of education was the method currently being used (36.5%). 2. The demand for hospice nursing education. 1) Over 70% demanded professional hospice education program, the highest demand was for the value and meaning of life followed by the role and qualification of the hospice team and the mental maintenance of a dying patient. 25 categories showed over 90% demand. 2) The highest demand was for the value and meaning of life (98.2%) and the lowest demand were for danjeon breathing(71.0%)and acupuncture(71.0%). 3) Other contents that need to be discussed in the professional hospice education program were hospice nursing, the attitude and reaction of death, bereavement care, and the prospects of hospice.

This study was designed to develop dish recipes using Heatsun sprouts to improve the sprouts' utilization and consumption. We created four kinds of dishes with Heatsun sprouts, including Acanthopanacis cortex, Kalopanax pictus, Aralia elata, and Cedrela sinensis, and analyzed their sensory properties and nutrients. In the sensory evaluation, the overall preference for all the dishes was scored higher than 3.0, Unnaumsun-dakgoginaengchae had the highest score (4.48) among the dishes. Unnamusun-dakgoginaengchae contained higher values of protein; vitamin A, E, and B6; and folic acid than the recommended dietary allowances (RDAs). The recipe for Dureupgokgammuchim was created to reduce the bitterness and the astringent taste of Aralia elata, and it was rich in vitamin C, E, and B6, as well as in folic acid and iron. Ogapisunkkonchijolim was cooked to reduce the fishy smell of a saury with the addition of Acanthopanacis cortex. It contained 1.5 times the protein RDAs, and high levels of antioxidant vitamins, including vitamin A, C, and E. Chamjugmandu was made by the mixing tofu and various vegetables without adding meat. It had the highest calorie count among the dishes, and its vitamin A, C, and E contents were higher than the corresponding RDAs.

The objective of this study is to determine the structural relationships among the infant's temperament, father's involvement in child-rearing, and the infant's social and emotional behavior. To this end, research was conducted with 330 parents of infants aged 1 and 2 in 55 day care centers located in J city and I city, Jeollabukdo. Frequency analysis, reliability analysis, correlation analysis, confirmatory factor analysis, and structural model equation analysis were conducted using SPSS 21.0 and AMOS 21.0. First, the results of the structural model equation analysis showed that the infant's temperament had a negative correlation with leisure and guidance, while it had a positive correlation with activity and impulsivity, which are external manifestations of their social and emotional behavior. Father's involvement in child-rearing had a negative correlation with the adaptability and mood aspects of the child's temperament, and also with general anxiety, an internal aspect of his or her social and emotional behavior. Social and emotional behavior had a positive correlation with the approach avoidance aspect of the infant's temperament. Second, according to the results of the analysis of the route between the variables, infant temperament was found to be a significant route, having a statistically negative correlation with father's involvement in child-rearing. The results of this study showed that infant's temperament and father's involvement in child-rearing had effects on the infant's social and emotional behavior, and suggested the importance of having a proper understanding of the educational implications of the father's involvement in child-rearing, in terms of its effects on the infant's social and emotional behavior.

Purpose: The purpose of this retrospective study is to investigate the degree of coincidence between the peer assessment rating (PAR) index and American Board of Orthodontics objective grading system (ABO-OGS) in the assessment of orthodontic treatment outcomes of Class I malocclusion cases. Materials and Methods: The sample consisted of 26 Class I patients. The PAR index was used for evaluation of pre-(T0) and posttreatment (T1) casts, and the ABO-OGS for assessment of T1 casts. If there was a reduction in PAR scores from T0 to T1 of more than 30%, the label 'PAR+' was given to the case, and if not, it was labeled 'PAR-'. If the ABO-OGS was less than 27, the label 'OGS+' was given to the case and if not, it was labeled 'OGS-'. 'A PAR-only qualified group' (PAR+), 'ABO-OGS-only qualified group' (OGS+), 'both indices qualified group' (PAR+/OGS+), and 'both indices disqualified group' (PAR-/OGS-) were compared with a Wilcoxon rank-sum test, sensitivity/specifi city test and Spearman's correlation test. Result: PAR scores for T0, T1, and percentage reduction were 21.1, 6.4, and 65.9%, respectively, and 35.4 for ABOOGS. The distribution of the 'PAR+/OGS+', 'PAR+', and 'PAR-/OGS-' group was 19.3%, 76.9%, and 3.8%, respectively. The T0-PAR, T1-PAR and PAR point reductions for the 'PAR+' group were significantly higher than those of 'PAR+/OGS+' groups (23.1 vs. 15.6; 6.7 vs. 4.6; and 16.5 vs. 11.0; all P<0.05). However, the PAR-percentage reduction and treatment duration between the two groups were not statistically different (70.0% vs. 67.0%, P=0.4325; 24.1 months vs. 25.0 months, P=0.4057). The T1-ABO-OGS score for 'PAR+' group was significantly higher than that of the 'PAR+/OGS+' groups (38.2 vs. 24.0, P<0.001). Conclusion: Since the fraction of the 'PAR+/OGS+' group was less than 20% and there was no significant correlation between PAR-percentage reduction and T1-ABO-OGS, development of a new index system for the accurate evaluation of treatment outcome is needed.

The critical need of forest road for enchanting the additional values of various forest products, in addition, giving more recreational opportunity to citizen, has been recognized. In this study the present author aimed to ascertain the most effective construction working plan of forest road being tit to Korean geographic condition. To execute this research program, four locations in national forest of Kangweon-do district and other four locations in private forest in Chollabuk-do district both where forest roads have previously been constructed were selected to analyze the effectiveness basing upon the various factors separately or in combination. The results are summarized as follows ; 1. The investment efficiency in forest road construction showed to increase in the area where terrain factors and district social factors rate is high, and to decrease in the area where forest status factors and forest road structure factors rate is high. So in future the Forest Resource Development Model of forest road should take more importance particularly on those area having terrain factor ratio is low. The extractable value of constructed forest road based on forest status factors rate is expected to increase in case of high considerably. 2. To construct of forest road for increasing multiple use of forests, forest road should be construct with priority on area where obtained total score by evaluation factors is high. And these evaluation factors should take possible determine the position of forest road construction. 3. The following five types of forest road basing upon function performance are suggested with regard to the place where road is constructed. (1) Forest Utilization Model ; where forest status factors and forest road structure factors rate are over 60%. (2) Forest Resource Development Model ; where terrain factors, forest status factors, forest road structure factors and district social factors rate are less than 60%. (3) Community Development Model ; where terrain factors, forest road structure factors and district social factors rate are over 60% but forest status factors rate are less than 60%. (4) Recreation and Health Model ; where terrain factors, forest status factors, forest road structure factors and district social factors rate are over 60%. (5) Multiple Use Model ; where both forest status factors and district social factors rate are over 60%.
