BACKGROUND/OBJECTIVES: This study analyzed the quality of lunches provided in senior leisure service (SLS) facilities and compared institutional foodservice (IF) and non-institutional foodservice (non-IF). SUBJECTS/METHODS: Data of 390 adults aged 65 years or older who ate lunches in SLS facilities were analyzed using the information from the 2013-2017 Korea National Health and Nutrition Examination Survey. The participants were classified into IF (n = 129) and non-IF (n = 261) groups according to meal type provided. The intake of major food groups, energy and nutrients, and nutrient adequacy ratio (NAR) and mean adequacy ratio (MAR) were analyzed. The diversity of meals was evaluated by food group patterns, dietary diversity score (DDS) and dietary variety score (DVS). Energy intake was adjusted in model 1, while energy and sex were adjusted in model 2. All confounding variables were adjusted in model 3. RESULTS: The intake of seafoods (P < 0.001 in models 1, 2, and 3), seaweeds (P < 0.01 in models 1 and 2), and dairy products (P < 0.05 in models 1, 2, and 3) was significantly higher in the IF group. No significant difference existed in energy intake; however, the intake of all nutrients except carbohydrate and vitamin C was significantly higher in the IF group. NAR of all nutrients, excluding vitamin C, was higher in the IF group, and MAR was also higher in the IF group (P < 0.001 in models 1, 2, and 3). The IF group had significantly higher DDS and DVS than the non-IF group (P < 0.001). CONCLUSIONS: The lunches provided in SLS facilities were better in terms of quantity and quality when provided through IF than through non-IF. More systematic foodservice programs should be implemented in SLS facilities, especially in facilities wherein users prepare their own meals.

The purpose of this study was to perform a kinematic analysis of Harai-goshi(hip throw) in superior female judo players. From our analysis, it appeared desirable for the player to shorten the duration of the technique for maximum results. It was also desirable for the player to draw the opponent backward while simultaneously maneuvering her close to her own body. A turning movement of the body toward the left side was found to be required for the technique, during which the player must lower the position of the center of gravity. During the subsequent angular change of the elbow, the player winds the elbow and, by moving the left shoulder, pulls the opponent toward her. The player lowers the body center by bending the left knee and letting the right knee extend, while turning the upper body and bending the hip joint. The player then draws the opponent in, contacts the opponent closely, turns, and stretches the right knee and hip joint rapidly and concisely, completing the move; it was also found to be desirable for the angular velocity to be increased for maximum efficacy.

The purpose of this study is to investigate the effects of eight weeks high fat intake and regular exercise in skeletal muscle and adipose tissue for Endoplasmic Reticulum (ER) stress in rats. This experiment involved 32 subjects (sprague-dawley rats) divided into four groups as follows: chow group (Chow, n = 8), chow and exercise group (Chow + EX, n = 8), high fat diet-induced hyperlipidemia group (HF, n = 8), and HF and exercise group (HF + EX, n = 8). As a result, there were significant decrease in body weight and abdominal fat, and blood lipid level was significantly improved by exercise for eight weeks (p < .05). There were variables changed about the skeletal muscle and ER stress in GRP78, XBP-1, ATF4, CHOP and JNK mRNA. There increased in mRNA factor by exercise, especially GRP78, and ATF4 mRNA were significantly increased in exercise (p < .05). However, there were increased in adipose tissue by exercise and there were significantly decreased in mRNA factor by high fat diet (p < .05). Consequently, this study suggests that the consistent exercise was more improved of obesity factor, such as dyslipidemia, hyperlipidemia, hyperglycemia, as well as body weight or abdominal fat. The response of ER stress in adipose tissue and skeletal muscle were more sensitive in exercise than high fat diet feed.

This paper describes a statistical analysis method for predicting a coast fishing boat's effective horsepower. The EHP estimation method for small coast fishing boats was developed, based on a statistical regression analysis of model test results in a circulating water channel. The statistical regression formula of a fishing boat's effective horsepower is determined from the regression analysis of the resistance test results for 15 actual coast fishing boats. This method was applied to the effective horsepower prediction of a G/T 4 ton class coast fishing boat. From the estimation of the effective horsepower using this regression formula and the experimental model test of the G/T 4 ton class coast fishing boat, the estimation accuracy was verified under 10 percent of the design speed. However, the effective horsepower prediction method for coast fishing boats using the regression formula will be used at the initial design and hull-form development stage.

본 연구는 농촌 노인의 여가활동 실태와 생활만족도에 미치는 요인을 밝히고, 이들이 참여하는 여가활동은 몇 가지로 분류되며, 여가 활동 참여도와 생활만족도는 어떠한 관계가 있는지 밝히기 위해 고흥군 도화면과 포두면에 거주하는 65세 이상 노인인구 220명을 대상으로 1998년 2월 16일부터 3월 3일까지 직접 면접을 통한 설문조사를 실시하여 분석한 결과는 다음과 같다. 첫째, 여가활동 내용에 있어서 가장 많이 참여하는 여가활동은 TV 시청이 가장 많고, 다음으로 친구들과 대화, 노인모임 활동, 걷기 및 산책, 친구 및 친척집 방문, 동물기르기 등의 순이었다. 둘째, 노인의 여가활동 유형은 적극적 자기 개발 활동, 소극적 자기개발 활동, 투기성 활동, 폐쇄형 활동, 안락한 고독활동, 우인중심 활동, 가족중심 활동, 종교활동의 8개 요인으로 분류되었다. 셋째, 노인들의 여가활동은 성, 연령, 월평균 수입, 교육수준 등이 통계적으로 유의한 관련이 있었고(P<0.05), 생활만족도와는 성, 연령, 월평균 수입, 교육수준, 건강상태 등이 유의한 관계가 있는 것으로 나타났다(P<0.05). 넷째, 노인의 생활만족도에 영향을 미치는 요인으로는 건강상태, 성, 월평균 수입, 여가활동, 의료보장 등이 통계적으로 유의한 변수로 선정되었다.(P<0.05) 따라서 노인의 삶의 질은 향상시키기 위해 제언을 하면 다음과 같다. 첫째, 건강상태가 생활만족도에 가장 관련이 있는 것으로 나타났으므로 만족스러운 노후생활을 위해서는 건강상태를 증진시키는 것이 요구된다. 이를 위한 방법으로 규칙적인 생활 체육을 장려하고, 노인전문 병원을 제도화 시키며, 가정 간호사업을 효율적으로 활성화 시키는 것이 바람직하다고 본다. 둘째, 월 평균 수입이 많을수록 생활만족도가 높은 것으로 나타났는데, 이는 소득 보장인 연금제도의 정착이 매우 중요한 문제임을 암시해 준다. 본 연구에서는 의료보호 대상자가 의료보험 대상자보다 생활만족도가 높았음을 볼 때, 규칙적이고 예측 가능한 수입은 생활만족도의 중요한 요인임을 유추 해석할 수 있다. 그러므로 경제적인 도움을 줄 수 있는 방법으로 노인들의 역할을 부여해 주는 것이 필요하다. 그 역할로는 장 담그기, 아기 돌보기, 김치감기, 봉투 만들기 등이 있을 수 있다. 끝으로 여가활동 참여를 많이 할수록 생활 만족도가 높게 나타났는데, 이를 위해 지역 주민과 더불어 노인이 함께 이용할 수 있는 복지센터를 설치하여야 한다고 본다. 또한 활용 가능한 인적, 물적 자원을 최대한 동원하여 여가 프로그램을 개발하고 발전시켜 나감으로써 노인의 적극적인 여가 활동 참여를 유도해 나가야 한다고 본다.
