Purpose: The purpose of this study was to investigate changes in movement strategies of lower limb joints depending on the type of heel during sit-to-stand. Methods: Twenty healthy females participated in this study. All subjects performed sit-to-stand three times each with three different types of heels - bare feet, 9 cm high-heeled shoes, and unstable shoes. Trails were conducted in random order. Three-dimensional motion analysis systems were used for collection and analysis of the kinematic data of lower limb movements. Results: Results of this study showed kinematic differences in pelvis, hip joints, knee joints, and ankle joints during sit-to-stand based on the type of heels. At the initial sit-to-stand, hip joint flexion, knee joint flexion, ankle joint flexion, and ankle joint inversion showed significant differences. The maximal angles of hip joint flexion, hip joint adduction, knee joint flexion, ankle joint flexion, and ankle joint inversion were significantly different, while hip joint adduction, pelvic forward tilt, hip joint rotation, knee joint flexion, ankle joint flexion, and ankle joint inversion differed significantly during the terminal of sit-to-stand. Conclusion: Therefore, the type of heel played an important role in selection of lower limb movements during sit-to-stand which were essential parts of daily life movements.

The purpose of this study was to determine discharge learning needs of patients undergoing thyroidectomy. The population of this descriptive study consisted of patients undergoing thyroidectomy in the Endocrine Surgery Unit of a university hospital between February and December 2013. The study included 251 patients who were discharged after thyroidectomy. Data obtained using the data collection form and the Patient Leaning Needs Scale (PLNS) were analyzed by frequency, mean, standard deviation, Kruskal Wallis and student-t tests. The mean age of the patients was $47.91{\pm}13.05$ and 76.1% were females. The PLNS total mean score was $208.38{\pm}34.91$, with the maximum score of $39.23{\pm}6.80$ on the subscale of treatment and complications and the minimum score of $19.45{\pm}4.70$ on the subscale of feelings related to condition. It was found that the PLNS total score of the patients was not influenced by age, gender, marital status (p>0.05). This study demonstrated that patients had high learning needs after thyroidectomy.

The objectives of this study were to classify the contents of lifestyle of adolescents, to investigate the relationships between lifestyles and appearance behavior, and to examine how appearance behavior was influenced by lifestyles and demographic variables of male and female adolescents. The method of the study was survey research by using questionnaires. Subjects were 414 high school students in Seoul: 176 were males and 238 females. Five dimensions of lifestyles were derived by factor analysis: ‘digital orientation', 'positive activity', 'achievement orientation', 'material orientation', and ‘frugality'. Digital orientation had, in case of the male, a positive relation with body-modification need, a positive one with appearance interest in female. Positive activity had positive relations with appearance interest and body satisfaction in both male and female. Appearance interest, weight interest, and body-modification need levels were significantly higher for female than for male, whereas body satisfaction were higher for male than for female. Appearance interest of male was influenced by positive activities and social stratification. Appearance interest of female was influenced by material orientation and positive activity. Body-modification need of male was influenced by digital orientation and frugality(-), that of female only influenced by material orientation. Fashion and brand preference of male was influenced by material orientation, frugality(-), and social stratification. In case of the female, fashion was influenced by positive activity, material orientation and frugality(-), brand preference influenced by material orientation and positive activity.

Locus of Control of Reinforcement (LOCR)' is considered as one of the most important factors on responsible environmental behaviors(REB). It is defined as 'an individual's perception of his or her ability to bring about change through his or her behavior'. This psychological construct is divided up into two directions: the external locus and internal locus. The internal locus is important as a predictor of REB. Recently, 'The Environmental Action Internal Control Index: EAICI' has been developed and it is a valid and reliable instrument to measure the relationship of two variables. The purposes of this study were to develop a strategy to reinforce the internal locus or to converse external locus to internal locus. and to verify the effects by EAICI. A new strategy, 'Self Control Management Strategy' was based on the characteristics of internal locus and the key idea of this was to self-control and to manage the courses by themselves. EAICI scores of the control group was 99.83. All of them were internal and the LOCR of females was more internal than that of the males. This strategy was applied when the instructions were carried out on seven environmental issues by the experimental group. According to the results. the seven points of the EAICI were increased significantly. Therefore this strategy is helpful in reinforcing the internal locus or to converse external locus to the internal locus.

The purpose of this study are to determine the proper radiographic measurements for hip deformity in spastic cerebral palsy patients, and the correlation of hip deformity with neurological involvement, ability of ambulation. Thirty children with cerebral palsy(22 males, 8 females) were evaluated by measurement of the migration index, acetabular index, center edge angle from bilateral hip APs(anterior posterior view). The result are as follows; 1. The incidence of hip dislocation, among the thirty children fifteen children were found to be dislocated, and more significantly high in non-walking group than in walking group(p<0.05) and in quadriplegia than in diplegia(p<0.05). 2. When compared to normal hip and dislocation hip, the migration index was significantly higher(p<0.01) and the center edge angle was lower in the dislocation hip than in the normal hip. 3. Correlation of radiological findings in right and left hip, the migration index and the center edge angle were highly correlated(p<0.01). We recommand regular intervals X-ray study for early diagnosis and management of hip dislocation in spastic cerebral palsy.

The purpose of this study is to investigate the relationship between suicidal ideation among Korean adolescents and factors such as family conflict, cohesion, organization of family activities, expressiveness, independence, achievement orientation, depression, stress, and support of friends and teachers, according to the individual student's parental type. The study sample consisted of 1908 high school students in the 11th grade from the city of Inchon. The results showed that in both males and females, suicidal ideation was greater in students from single-parent families than two natural-parent families and greater in step-parent families than in single-parent families. As an exploratory study, the analysis of factors influencing suicidal ideation according to parental type showed that the study model accounted for 33.6% for students from two natural-parent families, 42.8% for students from single-parent families and 84.5% for students from step-parent families, of the variance in suicidal ideation. This indicates that the study model is more appropriate for application to students from single-parent and step-parent families. In addition, the study shows that the factors of influence and the way these factors make an influence tended to differ according to parental type. This indicates that in terms of predicting suicidal ideation, it is more effective to study students according to parental type than as a whole. It also indicates that it is ineffective to take the same approach in dealing with suicidal ideation for students with different parental types.

Purpose: The purpose of this study was to develop a mentoring program for stress management among Korean adolescents and to assess the effects of the program. Methods: The nonequivalent control group (CG) pretest-posttest design was used in this study. The mentoring intervention was delivered to 18 middle school students (males and females) but nothing was done to the control group consisting of 18 students. The mentoring intervention was conducted by seven nursing students who participated in the program as mentors using various methods such as individual meetings and group activities. The dependent variable was stress level. Results: The program consisted of group and individual mentoring. At follow-up, although the mentees's satisfaction was high and they stated qualitatively positive experience, the difference of stress level between the two groups was not significant. Conclusion: If future mentoring programs reflect the limitation of the current program, they may have potential as developmentally appropriate interventions for stress management of adolescents, and enable nursing students to gain confidence in their professional capability.

Dose monitoring in CT patients requires accurate dose estimation but most of the CT dose calculation tools are based on Caucasian computational phantoms. We established a library of organ dose conversion coefficients for Korean adults by using four Korean adult male and two female voxel phantoms combined with Monte Carlo simulation techniques. We calculated organ dose conversion coefficients for head, chest, abdomen and pelvis, and chest-abdomen-pelvis scans, and compared the results with the existing data calculated from Caucasian phantoms. We derived representative organ doses for Korean adults using Korean CT dose surveys combined with the dose conversion coefficients. The organ dose conversion coefficients from the Korean adult phantoms were slightly greater than those of the ICRP reference phantoms: up to 13% for the brain doses in head scans and up to 10% for the dose to the small intestine wall in abdominal scans. We derived Korean representative doses to major organs in head, chest, and AP scans using mean CTDI_vol values extracted from the Korean nationwide surveys conducted in 2008 and 2017. The Korean-specific organ dose conversion coefficients should be useful to readily estimate organ absorbed doses for Korean adult male and female patients undergoing CT scans.

The leopard (Panthera pardus) is one of the most widespread felids worldwide. Despite their wide distribution, reliable data on leopard population densities are still inadequate for conservation and management strategies in different landscapes. In the present study, we estimated leopard density using camera traps in the Ranthambhore Tiger Reserve (RTR), Rajasthan, India, between December 2010 and February 2011, where leopards coexist alongside a high density of tigers (Panthera tigris), a larger predator (RTR). A sampling effort of 4,450 trap days was made from 178 camera trapping stations over 75 days, resulting in 46 suitable photo captures (25 right flanks and 21 left flanks). In total, 18 individuals (7 males, 8 females, and 3 unknown sexes) were identified using the right flanks, and the estimated leopard density was 8.8 (standard error=2.8) individuals/100 km². Leopard density appeared to respond to small prey (<50 kg weight) richness. As this is the first systematic study to provide baseline information on leopard density in RTR, it could form a baseline for comparison in future investigations.
