Purpose: The purpose of this study was to identify trends in intervention studies on childhood obesity in Korea. Methods: From 1996, when the first research paper on childhood obesity intervention was published, to 2015, 192 published papers were analyzed using descriptive statistics. Results: The number of studies increased sharply between 1996 and 2007, but declined slightly from then. The majority of studies involved only children as intervention participants. Most were elementary students, and overweight and obese children. Exercise therapy was the most common type of intervention. Parental participation was found in 35 studies, while teacher's participation was found in only one study. In many studies physiological indicators were used as measurement variables, but follow-up was done in only 10 studies. Finally, only a few studies applied a conceptual framework, while a quasi-experimental research design was used for most studies. Conclusion: Examination of trends in intervention studies on childhood obesity in Korea, shows there has been a quantitative increase but not enough improvement in terms of the quality of interventions. Findings in the present study suggest that it is necessary to seek diversity in terms of study participants, interventions and evaluation method along with quality improvement in research methodology.

The aim for this study is to suggest a practical model to measure the financial values of the achievements from corporate research and development(R&D) projects. Performance indicators for R&D projects were identified from the extensive literature reviews and the evaluation methods to convert them into financial values were proposed to overcome the problems of excessive predictions and subjective expert assessments in existing methods. The proposed model was applied to R&D projects of an IT company in Korea for its validity test. The model is expected to be a turning point in economic evaluation of corporate R&D projects in general due to its practical and reasonable scheme.

The purpose of this study was to investigate the different aspects of word-initial liquid sounds in Korean according to generations. Five women in their 50s and seven in their 20s participated in the experiment. We examined FL (formant of liquids) and voice sustained time by using Praat software. Three English native speakers were asked to judge the Korean speakers' recorded speech samples for marking [l] or [r] using evaluation sheet. The results of the two experiments revealed three important aspects. First, there was a statistically significant difference between the two groups in the FL of the words 'racket' and 'ruby.' Second, we found statistically significant differences in 'rhythm', 'ruby' and 'litter' from the measurement of the duration of the acoustic data. Third, there was no difference in pronunciation between the two groups according to the phonemes of the original language. The results of this study showed that it is difficult to say that the duration of word-initial liquids and the phoneme difference of the original language are indicators to distinguish the word-initial liquids between generations. Also, it was seen that the pronunciation of Korean word-initial liquid sounds varied across generations.

Purpose: The purpose of this study was to develop a Health Mileage Program (EHMP) to promote exercise amongst the elderly and assess the feasibility of the program. Methods: A literature review to identify the effects of exercise in the elderly was conducted. Relevant cases were investigated and in-depth interviews with exercise instructors were conducted, after which the EHMP was developed based on the assessment and tested in three regions. The outcome was evaluated using indicators such as attendance rate, number of participants, proportion of participants who received health education, and proportion of participants who measured their physical and mental status. Results: Based on assessment, we developed an EHMP composed of four steps. Following application of the EHMP in three regions, ${\geq}80%$ of the participants received incentives. Additionally, ${\geq}85%$ of participants underwent measurement of their physical and mental status. The proportion of participants who received health education differed among regions. Conclusion: The EHMP program increased participation and interest in exercise programs for the elderly. However, there is concern regarding availability due to regional differences in resources related to elderly exercise; therefore, it will be necessary to invest in infrastructure, including facilities, and knowledgeable instructors.

Despite the wide industrial applications of planetary gear trains, the relationship between the design parameters (tooth profile, carrier mass, etc.) and performance (strength, vibration, noise, etc.) remains poorly understood. A significant amount of research has focused on transmission errors, which are measurable performance indicators directly related to the design parameters. Herein, an experimental test rig for a single-stage planetary gear set built using digital angular encoders and gap sensors is described. To study the static and dynamic characteristics of this planetary gear train, the transmission errors and sun gear orbit are analyzed from the data measured under various levels of torque and speed. The transmission errors of the gear train decrease 40% when the speed increases from 30 to 600 rpm with an output torque of 39.2 Nm, and increase 22% when the output torque increases from 19.6 to 39.2 Nm with an input speed of 30 rpm.

To investigate the effects of exercise-training on fat distribution several indicators of body fatness(percent body fat skinfolds thickness body circumference) were assessed in 128 healthy male subjects submitted to an 8-wk high intensive exercise-training. The subjects(average age=20.3$\pm$1.3 yrs) exercised 5 days/week. Daily energy intake and expenditure wee recorded. The results obtained are summarized as follows : 1) Through exercise-training lean body mass increased significantly (changes : 0.5$\pm$1.5kg; p=0.000) decreased significantly. 2) Suprailiac was the most reduced site by exercise-training among eight site skinfolds. Central skinfolds were changed more by exercise-training than peripheral skinfolds with reduction of 1.7$\pm$2.1mm and 0.4$\pm$1.8mm respectively. Central site circumferences were reduced more by exercise-training than peripheral site circumferences. 3) As a result of analyzing 12 of the fattest(top 10% of weight) and 12 of the leanest men(bot-tom 10% of weight) it indicated that there was a significant reduction of fat tissue in body composition and skinfolds thickness for the fat group. However there was no significant change for the lean groups. 4) Correlational analysis showed that predicting changes in body fat by infrared(NIR) measurement seemed to be closely associated with changes in body fat by Kim's equation and Katch's equation in young men.

In the current competitive marketplace of real estate business, tenant satisfaction measurement is one of the important indicators to monitor competitiveness in industrial property development. It has become an industry standard to measure tenant satisfaction, commonly called customer satisfaction. Customer satisfaction has become the widely used metric to manage customer loyalty (Keiningham, Gupta, Aksoy, & Buoye, 2014). The aim of this research is to determine the impact of property management services on tenants' satisfaction with the three identified variables i.e. facility management, perceived quality and lease management. Structural equation modeling (SEM) is applied to build constructs and test the hypotheses with the collected survey samples. Of the three variables, facility management is the most influential factor that leads to tenant satisfaction with industrial buildings. Next, perceived quality is another important factor that contributes to tenants' pleasure. Compared with these two, lease management fares worse, having the least extensive effect on tenant satisfaction, and could be disregarded. The ultimate impact of tenant satisfaction is about tenant retention and recommendation. The overall findings of this research will potentially help real estate developers to develop a better property management system, leasing program and tenant retention strategy.

Purpose: The purpose of this study was to attempt an accurate understanding of the quality of life for the children and provide basic materials for application to nursing research, intervention and further theoretical development. Method: Data obtained from such research methods as the lexical and literature review were analysed according to Walker and Avant's(1995) process of concept analysis. Results: As a result of analysis, it was found that the attributes of the concept of the quality of life for the children included value/acceptance, family relationship, safety, good relationship with friends, right of children, school life, parent relationship, leisure, economical stability, not child abuse, and health. There was the coexistence between antecedent element and the outcomes of subjective judgement - health, family, economic strength, education, friends, welfare, social-cultural environment which indicates the coexistence of positive and negative emotions. Conclusion: nursing intervention should be provided for children by concentrating focus on the coordination of internal and external situations in order to prompt them to express their life with positive emotions. Experiential reference was used to suit the purpose of this study based on the use of objective and subjective indicators, and the development of the instrument considering the children were proposed because of the absence of the unified measurement instrument.
