Objectives: This study aimed to assess the association between physical activity and health-related quality of life (HRQOL) in Koreans. Methods: A total of 9,689 adults(${\geq}19$ years, 4,036 men) from the Fourth National Health and Nutrition Examination Survey(2007-2008) were examined by the International Physical Activity Questionnaraire (IPAQ)-short form and Korean EuroQol-5 Dimension(KEQ-5D). Results: For the physical activity by IPAQ, 'Inactive group' was 75.3%, 'Minimally active group' was 23.5%, and 'Health-Enhancing Physical Activity(HEPA) group' was 1.2%. The mean HRQOL index was $0.89{\pm}0.13$. These relations of physical activity and HRQOL remained significant after adjustment for age, sex, smoking, subjective health status, stress, depression, and socioeconomic status variables (Adjusted $R^2$ = 0.334). Conclusions: Physical activity was associated with health-related quality of life. Physically active group had higher health-related quality of life than the inactive group.

This study has developed a design indicator required to promote green remodeling in school facilities. And, implemented the green remodeling pilot test on the school facilities that are planning actual remodeling. This pilot test suggested user participation design methodology such as verification of the developed design indicator, design goal setting, evaluation and adjustment of design proposal. The Green Remodeling Design Indicators were classified into 3 large categories of architectural performance, usability, and design through analysis of cases related to 'green buildings' and 'remodeling'. We have developed nine middle categories such as architectural and structural performance, facility performance, environmentally-friendly, circulation, space, amenity, harmony with surroundings, form and symbolization. In addition, 42 detailed indicators were developed for each category, including general, functional, and special indicators. For the verification of this study, two green remodeling design workshops were conducted for Gwangju J elementary school. The first design workshop presented the importance of the design indicator and set the goal of the design plan of green remodeling for project. And, the second Workshop presented the evaluation of the satisfaction with the design and the direction of future adjustment for project. The design indicator developed in this study can be utilized as a design indicator of design quality management and decision system for the school green remodeling in the future. In addition, by accumulating information on the Green Remodeling Project, it is necessary to spread green remodeling and construct a sustainable building environment.

Self administered checklist is needed to be developed to evaluate ergonomic risk factors. This study was conducted to develop self administered form of American National Standards Institute (ANSI) Z-365 checklist which represents comprehensive ergonomic risk factors, and to evaluate validity of this checklist. This study had been conducted from May 2004 to July 2005, of which subjects were 147 workers from 4 workplaces. Response rates for every items of self administered form of ANSI Z-365 were evaluated. To estimate the validity of checklist, relationship between the checklist grade that ANSI recommended and work-related musculoskeletal disorders (WMSDs) symptom were calculated with and without adjustment of related variables. To evaluate the utility of checklist, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated. Because response rates of almost items were over 90 %, item development was successful. Because the checklist was related with WMSDs symptom after adjusting related variables, the checklist might represents ergonomic risk well. Because of low sensitivity and NPV, high specificity and PPV, the checklist is not suitable for screening tool. The checklist has better relationship with more severe symptom. Because of high specificity of the checklist, using it with high sensitive tool would enhance it's utility. Further study to develop high sensitive and comprehensive self administered ergonomic checklist is needed.

The absorption wavelength of the protonated retinal Schiff base can be controlled by the surrounding environment. An external anion is related to fine adjustment of the absorption wavelength. The addition of anion to retinochrome solution caused blue shift in spectra. The increase of the shift was dependent on the ion concentration. The large shift value was obtained as 20 nm at the saturated concentration of nitrate. The shift intensity for the nitrate addition exceeded that of chloride. Seemingly, it depends on the ionic strength or lyotropic character of the anion. However, neither of sulphate nor gluconate ion showed remarkable blue shift. These phenomena were accounted for with (1) delocalization of the positive charge in the conjugated polyene system, (2) ionic bonding strength between the counter ion (glutamate) and the proton, and/or (3) interaction of the added anion with the proton on Schiff base.

Objective : An adjustable Ghajar guide is presented to improve the accuracy of the original Ghajar guide technique. The accuracy of the adjustable Ghajar guide technique is also investigated. Methods : The coronal adjustment angle from the orthogonal catheter trajectory at Kocher's point is determined based on coronal head images using an electronic picture archiving and communication system. For the adjustable Ghajar guide, a protractor is mounted on a C-shaped basal plate that is placed in contact with the margin of a burrhole, keeping the central $0^{\circ}$ line of the protractor orthogonal to the calvarial surface. A catheter guide, which is moved along the protractor and fixed at the pre-determined adjustment angle, is then used to guide the ventricular catheter into the frontal horn adjacent to the foramen of Monro. The adjustable Ghajar guide technique was applied to 20 patients, while a freehand technique based on the surface anatomy of the head was applied to another 47 patients. The accuracy of the ventricular catheter placement was then evaluated using postoperative computed tomography scans. Results : For the adjustable Ghajar guide technique (AGT) patients, the bicaudate index ranged from 0.23 to 0.33 ($mean{\pm}standard$ deviation [SD] : $0.27{\pm}0.03$) and the adjustment angle ranged from $0^{\circ}$ to $10^{\circ}$ ($mean{\pm}SD:5.2^{\circ}{\pm}3.2^{\circ}$). All the AGT patients experienced successful cerebrospinal fluid diversion with only one pass of the catheter. Optimal placement of the ventricular catheter in the ipsilateral frontal horn approximating the foramen of Monro (grade 1) was achieved in 19 patients (95.0%), while a suboptimal trajectory into a lateral corner of the frontal horn passing along a lateral wall of the frontal horn (grade 3) occurred in 1 patient (5.0%). Thus, the AGT patients experienced a significantly higher incidence of optimal catheter placement than the freehand catheterized patients (95.0% vs. 68.3%, p=0.024). Moreover, none of the AGT patients experienced any tract hemorrhages along the catheter or procedure-related complications. Conclusion : The proposed adjustable Ghajar guide technique, using angular adjustment in the coronal plane from the orthogonal trajectory at Kocher's point, facilitates accurate freehand placement of a ventricular catheter for hydrocephalic patients.

A survey of professionals employed in marine related fields was conducted on subjects related to marine meteorological forecasts and special reports. The outcome of the survey indicated that the respondents were overall satisfied with the determination of the zones related to marine meteorological forecasts and special reports and with the number of forecast factors, but in regards to the questions about specific adjustment methods, it was found that the respondents perceived a need for adjustment. In addition, although there was a high consensus among the respondents that the criteria for watch and warning in the marine special reports were suitable, they voiced the opinion that it will be necessary to implement changes in the current criteria for watch and warning in order to further improve the compatibility of the criteria. The survey found that there was a high level of utilization for the marine meteorological information provided by the Korea Meteorological Administration(KMA), and that respondents mostly acquired this information via internet and TV. On the other hand, however, the satisfaction level regarding the accuracy of the marine meteorological information was low in comparison to the utilization level. The survey regarding areas for improvement in the forecasts and special reports also indicated that the need for 'improvement in the accuracy of forecasts' was cited most frequently.

Purpose: The purpose of this study was to investigate the mediating effects of self-esteem and self-resilience while identifying the relationship between bullying victimization (being bullied) and depression based on a longitudinal study design. Methods: Participants were adolescent cohort of 1,971 middle school students participating in 2013 and 2014 Korean Children and Youth Panel Survey conducted by National Youth Policy Institute. Data were analyzed by Pearson's Correlation and regression. Results: The major findings are as follows. First, self-esteem and self-resilience were positively related to each other and negatively related to depression and bullying victimization. Second, bullying victimization effected the level of depression of adolescents and self-esteem played a mediating role between bullying victimization and depression while self-resilience did not. Conclusion: The results suggest that emotional factors continue to play an important role in promoting psychological adjustment of victims of bullying. Therefore, interventions are more likely to be successful if they focus on emotional skills development of adolescents.

The present study was designed to examine how much Korean elementary school children used the YouTube, and tested whether the overuse of YouTube might be related to adjustment problems such as low parental warmth, low self-esteem, and low school satisfaction. Two hundred and thirty-eight elementary school students answered a questionnaire enquiring about their YouTube use, parental practice, self-esteem, and school satisfaction. Results indicated that more than half of the participants watched the YouTube at least one hour per day, and 15.6% of them watched the YouTube more than 3 hours per day. Negative relationships between YouTube watching time and parental warmth, self-esteem, and school satisfaction were found. YouTube watching time also partially mediated between parental warmth and adjustment problems. Parental rejection and overprotection were not related to children's YouTube watching time. These study results can be used as seminal data for developing children's YouTube watching guidelines.
