Objectives: This study evaluated the dietary habits and health behaviors of Korean adults according to their physical activity. Methods: Adults aged 19~64 years, who participated in the 2016~2018 National Health and Nutrition Examination Survey, were enrolled in this study. The subjects were classified into the physical inactivity group, aerobic physical activity group, strength exercise group, and combined exercise group. Results: Significant differences in skipping breakfast, frequency of eating out, dietary supplements, and alcohol drinking status were observed among physical activity groups (P < 0.001). The combined exercise group had the highest % KDRI of protein, vitamin A, thiamin, riboflavin, niacin, calcium, potassium, and iron (P < 0.001). The physical inactivity group had the highest obesity rate (35.1%), and they perceived their body image type to be obese. In the combined exercise group, 47.8% of respondents said they were in good health (P < 0.001). The health-related quality of life score of the physical inactivity group was the lowest, with a score of 0.94. The metabolic syndrome risk rate of the combined exercise group was lower at 0.62 times (95% CI, 0.51-0.75) than the physical inactivity group. Conclusions: The physical activity type was associated with metabolic syndrome. These results can be useful for supporting dietary education and physical activity programs for adults.

The studies on chloride diffusion of concrete have been done so far by many researchers. However, there are few studies that present the effects of other attacks on chloride diffusion properties. Therefore, in this study the experiments are carried out to show the effects of combined attacks, such as carbonation, sulfate attacks, on chloride diffusivity in concrete. The specimens are made by varying cement type and replacement ratio of fly ash. The results show that cement type and replacement of fly ash do not affect greatly chloride diffusion properties. And concrete treated by combined attacks show a little higher chloride content than those treated by chloride solution only. Therefore, the effects of these factors should be taken into account in predicting the penetration of chloride ion in concrete.

In this study the relative effects among trees, cars, wires and building facades on visual preference are measured with the photo-montage scenes, which were synthesized by computer graphic programs. In addition to these experiments, the interaction of each elements of streetscapes have been investigated. The results of this study can be summarized as follows ; (1) It was found that trees had a remarkable positive effect on preference for streetscapes, wires had a moderate negative effect, cars had a trivial effect and the effects of building facades were medium. (2) It was investigated that the building of residential type was most preferred among commercial, residential, and office building types. The next preferred building facade was the commercial type. (3) The interaction of each element of streetscapes also have effects on preference. Especially, it was found that the combined effects of building-wire and building-cars were more notable than other combined effects of two elements.

Combined generation system of Photovoltaic and wind generation have shortcoming that is different output power according to change of weather. So, the combined generation system is required backup system that such as a storage battery to supply energy, when not enough photovoltaic and wind power source for power supply equally and continually because the energy source is changeable and stable through change of weather as irradiation. temperature, wind speed. wind direction. seasons, etc.

This paper introduces a conceptual design of a combined scroll expander-compressor unit for a fuel cell. Since air discharged out of the fuel cell stack has still high pressure energy, some power can be extracted from the air by directing it to pass through an expanding device. Such extracted power can be used to drive an auxiliary compressor. For this purpose, a scroll type expander coupled to a scroll type compressor was designed for a 1kW-class fuel cell. The orbiting scroll members of the expander and the compressor were made to share three of common drive shafts installed in the mid frame plate. Performance analysis for the combined expander-compressor unit showed that the installation of this unit could reduce the auxiliary power consumption in the fuel cell by about 42%.

In this paper, we propose that college counselors be more knowledgable of adult ADHD symptoms and develop better understandings of subtypes of the disorder. The findings in this study show that college students with different subtypes of ADHD symptoms experience different types of psychological maladjustment as well as different levels of psychological distress. Specifically, combined-type trait group show the highest levels of each of subscale of SCL-90-R among the other groups (i.e., normal, predominant inattentive subtype, hyperactive-impulsive type). Furthermore, combined typed trait group show significantly higher levels of animosity and paranoid ideation than the others. Therefore, college counselors need to provide effective interventions addressing intense emotion and cognitive distortion among college students with ADHD combined symptoms.

Traumatic anterior shoulder dislocation combined with scapular fracture in elderly patients is relatively rare. In this case, a patient visited Emergency Room of Dong-A University Hospital for shoulder pain after falling off a ladder. Radiographs demonstrated anterior shoulder dislocation with displaced Ideberg type IIb scapula (glenoid fossa) fracture combined with a large rotator cuff tear on magnetic resonance imaging. We performed arthroscopic rotator cuff repair, but a large fragment in the inferior glenoid was left untreated. At the 1 year follow-up visit, the pain visual analogue scale of the patient was 2, the American Shoulder and Elbow Society score was 88 and the patient had gained nearly full range of motion without any apprehension.

The combined anomaly of pulmonary stenosis with atrial or ventricular septal defects is usually associated with decreased pulmonary blood flow and right to left shunt, and result in generalized cyanosis. Non-cyanotic pulmonary stenosis patients have generally been considered to have isolated pulmonary stenosis with intact septa. We are going to report a case of pulmonary stenosis with septal defects who have no frank cyanosis at rest because of the predominant intracardiac shunt from left to right. Recently, we managed surgically a case of pulmonary valvular stenosis combined with secundum type atrial septal defect, type II ventricular septal defect, and patent ductus arteriosus. The clinical manifestations of this patient were exertional dyspnea, frequent upper respiratory infection, chest discomfortness and lethargy since late childhood and these had been progressively aggravated. Pulmonary valvular stenosis, atrial septal defect and ventricular septal defect were closed through simply right atriotomy and patent ductus arteriosus through pulmonary arteriotomy. Immediate postoperative course was uneventful and one year follow up is excellent.

목적: 비 운동선수에 있어 제 2형 SLAP 병변의 관절경적 봉합수술의 결과를 알아보고 단독 제2형SLAP 병변이 있는 군과 봉합이 필요치 않은 극상건의 부분층 파열을 동반한 군간의 임상적 결과를 비교해보고자 하였다. 대상 및 방법: 2005년 7월부터 2007년 1월까지 제 2형 SLAP 병변에 대해 관절경적 봉합수술을 시행 받은 총 142예의 환자 중 50세 미만 비 운동선수를 대상으로 하였으며 이 중 같은 부위에 수술, 골절, 반복적인 탈구의 병력이 있거나, 봉합을 요하는 회전근개 전층 또는 50% 이상의 부분층 파열을 동반한 경우, 감염, 관절염, 염증성 질환을 동반한 경우는 제외하여 총 19예의 환자를 대상으로 하였다. 이 중 13예는 봉합이 필요치 않은 극상건의 부분층 파열을 동반하고 있었고(그룹 I), 6예는 단독 제 2형 SLAP 병변을 가지고 있었다(그룹 II). 평균 연령은 36.7세(29-49세)였으며 평균 증상 기간은 39.1개월(3-216개월)이었고 평균 추시 기간은 19.0개월(12-27개월)이었다. 외상의 병력은 그룹 I에서 9명, 그룹 II에서 5명 있었다. 모든 환자에서 술 전후로 관절운동범위, 통증 및 기능 VAS, Constant 점수 및 UCLA 점수를 측정하였다. 결과: 그룹 I에서 견관절의 외회전은 최종 추시시 의미있게 감소하였으며(p=0.003) 그 밖의 관절운동 범위는 그룹에 관계없이 모두 술전 상태로 회복되었고(p>0.05), 그룹간에도 차이가 없었다(p>0.05). 최종 추시에서 모든 평가 점수(Constant 점수, UCLA 점수, 통증 VAS, 기능 VAS)는 술 전에 비해 통계적으로 유의하게 향상되었다(p<0.05) : UCLA 점수는 $22.8{\pm}5.2$에서 $32.8{\pm}2.1$; Constant 점수는 $79.4{\pm}8.6$에서 $94.9{\pm}4.3$; 통증 VAS는 $5.4{\pm}2.7$에서 $1.1{\pm}1.4$; 기능 VAS는 $63.2{\pm}15.3$에서 $93.4{\pm}7.3$으로 향상되었다. 하지만 평균 UCLA 점수 및 Constant 점수의 그룹간 비교에서 두 그룹간 통계적으로 유의한 차이는 보이지 않았다. 결론: 비 운동선수에 있어 제 2형 SLAP 병변의 관절경적 봉합술은 임상적으로 좋은 결과를 보였으며 동반된 극상건의 부분층 파열은 1년 추시에선 최종결과에 영향을 미치지 않았다.
