Purpose: This study was conducted in order to determine the effects of a health promotion program on perception of health behavior, physical fitness, and body composition in child care helpers. Methods: The study had a one group pretest-posttest quasi-experimental design. Data were collected from 38 child care helpers from July 6 to November 9, 2013. The health promotion program consisted of health education, self-exercise, encouragement, and identification. The following data were collected perception(perceived benefit, barrier, and self-efficacy), physical fitness(balance, grasp power, and flexibility), and body composition(body mass index, body fat ratio, waist circumference, and basal metabolic rate) and analysis was performed using on SPSS WIN 18.0. Results: Self-efficacy showed a significant increased. Body mass index, body fat ratio, and waist circumference showed a significant decreased. No significant difference in perceived benefit, barrier, physical fitness, and basal metabolic rate was observed between pre-test and post-test. Conclusion: This health promotion program had an effect on self-efficacy and body composition in child care helpers. Therefore, this health promotion program for child care helpers can be recommended as an effective nursing intervention.

Simultaneous observations of MODIS (Moderate-resolution Imaging Spectroradiometer) onboard the Aqua and Terra satellites and weather station at ground near the Inchon International Airport (37.2-37.7 N, 125.7-127.2 E) during the period from December 2002 to September 2004 have been utilized in order to analyze the characteristics of satellite-observed infrared (IR) and visible data under fog and clear-sky conditions, respectively. The differences $(T_{3.7-11})$ in brightness temperature between $3.75{\mu}m\;and\;11.0{\mu}m$ were used as threshold values for remote-sensing fog (or low clouds) from satellite during day and night. The $T_{3.7-11}$ value during daytime was greater by about 21 K when it was foggy than that when it was clear, but during nighttime fog it was less by 1.5 K than during nighttime clear-sky. The value was changed due to different values of emission of fog particles at the wavelength. Since the near-IR channel at $3.7{\mu}m$ was affected by solar and IR radiations in the daytime, both IR and visible channels (or reflectance) have been used to detect fog. The reflectance during fog was higher by 0.05-0.6 than that during clear-sky, and varied seasonally. In this study, the threshold values included uncertainties when clouds existed above a layer of fog.

정지궤도 기상위성자료의 시차오류(Parallax error)는 기상위성 산출물 중에서 구름과 관련된 산출물의 위치 오류를 발생시키기 때문에 강수의 유무와 강도를 옳게 분석하더라도 강수위치 선정에 오류를 발생시킬 수 있다. 본 연구에서는 시차오류를 보정하는 방법을 제시하고 보정방법을 검증 및 적용하는데 목적이 있다. 시차오류에 의한 구름위치 보정은 첫째, 원래의 위성친정각파 구름고도를 입력 자료로 보정된 위성천정각을 산출한다. 둘째, 보정된 위성천정각과 위성방위각을 이용하여 위성시차오류를 보정하여 구름의 원래 위치에 가깝게 옮겨준다. 시차오류는 위성천정각이 증가하고 구름고도가 증가 할수록 더 크게 나타나며, 동아시아지역($20{\sim}50^{\circ}N$)에서는 최대 약 25km의 구름위치오류가 발생 할 수 있다. Terra MODIS(Moderate-Resolution Imaging Spectrometer)의 센서천정각 $20^{\circ}$이내의 관측 자료와 검증한 결과 시차 보정된 구름위치가 원래 위치에 가깝게 개선된 것을 확인 할 수 있었다. 본 논문에서 제시한 정지위성 시차오류 보정방법은 향후 아시아지역의 여러 정지궤도 기상위성의 영상 활용성 증대에도 기여할 것이다.

The purpose of this study was to investigate muscle activity of the lower limbs when walking in jeans in order to obtain basic information for development of new jeans patterns with excellent movement adaptability. Using three types of jeans (basic, medium, and slim) with different ease on hip, knee circumference, and crotch length, and two different types of shoes, Electromyogram (EMG) of the lower limbs muscle was measured for four healthy subjects walking on treadmills and stairs. EMG of vastus lateralis, semitendinous, tibialis anterior and medial head of gastrocnemius muscles was measured. The muscle activity was assessed in RMS (Root Mean Square) value of the EMG. On the treadmill in sneakers, only the vastus lateralis muscle showed a significant difference in RMS value depending on patterns. Basic and medium jeans allowed higher muscle activity than trunks of slim jeans did. On the treadmill in high heels and slim jeans, the RMS values of all muscles were significantly smaller than in basic jeans, whereas no significant differences were shown while in trunks or medium jeans. On the stairs either in sneakers or in high heels, no significant differences were shown between all muscle activities for all types of jeans. On the treadmill, greater fatigue was induced in all muscles from walking in high heels than in sneakers for all jeans patterns. When walking on the stairs wearing either type of shoes, however, the effect of jeans pattern on muscle activities was different from muscle to muscle.

In adults, mallet finger is a traumatic zone I lesion of the extensor tendon with either tendon rupture or bony avulsion at the base of the distal phalanx. High-energy mechanisms of injury generally occur in young men, whereas lower energy mechanisms are observed in elderly women. The mechanism of injury is an axial load applied to a straight digit tip, which is then followed by passive extreme distal interphalangeal joint (DIPJ) hyperextension or hyperflexion. Mallet finger is diagnosed clinically, but an X-ray should always be performed. Tubiana's classification takes into account the size of the bony articular fragment and DIPJ subluxation. We propose to stage subluxated fractures as stage III if the subluxation is reducible with a splint and as stage IV if not. Left untreated, mallet finger becomes chronic and leads to a swan-neck deformity and DIPJ osteoarthritis. The goal of treatment is to restore active DIPJ extension. The results of a six- to eight-week conservative course of treatment with a DIPJ splint in slight hyperextension for tendon lesions or straight for bony avulsions depends on patient compliance. Surgical treatments vary in terms of the approach, the reduction technique, and the means of fixation. The risks involved are stiffness, septic arthritis, and osteoarthritis. Given the lack of consensus regarding indications for treatment, we propose to treat all cases of mallet finger with a dorsal glued splint except for stage IV mallet finger, which we treat with extra-articular pinning.

This study held a questionnaire for men in their 60s or above to analyze the market research of slacks, understand the characteristics of their lower body types, and provide the basic data for the slacks pattern-making fitting the body types of senior citizens. The findings are as follows. According to the results of a questionnaire, elderly men preferred order-made slacks for better fitness, but they favored ready-made owing to the matter of prices. In particular, the girth of waist was the most considered when purchasing. However, as most customers tended to repair slacks length and the waist part, their unsatisfaction with sizes was rather high. In body measurements, elderly men had higher variable coefficients or more individual differences in the items of thickness and angles than in those of height, length, and girth. Factor analysis revealed 5 front and 6 side factors. According to the results of front-side somatotype analysis, pimento-flat, trapezoid-flat, and bent-flat types require narrower pattern designs in down-upper width than the middle-aged class. In addition, pimento-protruded hip and straight-jar types need to be designed in the same amount as in the middle-aged class. Based on the questionnaire results, down-upper length as 1cm above real dimensions was analyzed to have superior sense of wearing.
