The main objective of this study is to analyze characteristics on the somatotype of modern adult women In order to standardize of products. The sample for this work chosen from data which were collected and measured by Size Korea during two years(2003~2004). In order to analyze feature of the somatotype of modern adult women, analysis was peformed in 1,371 subjects(645 twenties women, 725 thirties women) about 21 body parts such as height(4 parts), width(3 parts), thickness(3 parts), circumference(7 parts), length(3 parts) and body weight. According to the result of analysis, it was found that the twenties group was near in slender somatotype, whereas the thirties group was near in fat somatotype compared to standard somatotype.

The purpose of this study was to investigate the correlation and characteristics between electromyographic (EMG) activities of lower leg muscles and the posturographic assessment of static balance control in normal adults. Twenty-four young, healthy adults(12 males, 12 females) participated in the study. Center of pressure (COP) parameters were obtained using force platform as total path distance, total sway area, X mean frequency and Y mean frequency for 20 seconds in the following conditions: (1) comfortable standing with eyes opened or closed, (2) uncomfortable standing (feet together) with eyes opened or closed, (3) virtual moving surround delivered using Head mount display (HMD) with four different moving patterns. The virtual moving patterns consisted of close-far, superior-inferior tilting (pitch), right-left tilting (roll), and horizontal rotation (yaw) movements. Surface electromyographic activites were recorded on the tibialis anterior, peroneus longus, medial and lateral heads of gastrocnemius muscles under each condition. Correlation between the posturographic measures and EMG activities were evaluated. Total path distance and total sway area of COP were significantly increased during uncomfortable standing. EMG activity of tibialis anterior was significantly more during uncomfortable standing and virtual moving surround stimulation than during comfortable standing. Total path distance and sway area of COP during comfortable standing with closed eyes showed significant positive correlation with the EMG activities of the lateral head of gastrocnemius muscle. Total path distances and total sway area of COP during muscle. Total path distances and total sway area of COP during presentation of virtual moving surround also had significant positive correlations with EMG activities of the lateral head of gastrocnemius muscle under close-far movement.

인간의 각성은 감성의 한 차원을 차지하여 인간의 작업수행의 효율성에 미치는 영향이 크다. 각성의 정확한 측정 및 분석은 인간의 작업에 생산성 극대화를 제시할 수 있다 그러나 각성은 자극유형에 따라 종류가 다르게 나타난다. 본 연구는 이러한 각성의 유형에 따른 생리신호의 반응을 측정하여 각성종류별 생리적 반응차이를 제시하고자 한다. 20명의 대학생이 각기 다른 각성자극인 신체적 각성 및 인지적 각성을 유발하여 생리신호 반응을 측정, 분석하였다. 결과적으로 인지적 각성과 신체적 각성은 자율신경계 반응에서 유의한 차이를 보이지 않은 반면, 인지적 각성에서 중추신경계 반응이 작업계획 단계에서 신체적 각성보다 유의한 차이를 보였다.

Elution solvent used in HPLC was ethylacetate : acetonitrile (4 :1), and mobile phases for solvent A and B were water : methanol : acetonit rile : phosphric acid (700:250:50:0.2) and 100% acetonitrile respectively. The detector and absorbency used in HPLC was UV 266 nm. This study showed the reduction effect of 99.1% for organic solvents, 94% for experimental steps, 95% for analytical time and manpower and 98.9% for costs compared with korea food standard method. The average recovery rates for chicken, bovine, pork and milk were 67.7% 96.2 %, 67.7%-96.6%, 70.0%-96.2%, and 13.8%-97.8%.

여러 연구자들의 연구결과를 토대로 하여 침채류의 염장 발효과정중 나타나는 여러가지 화학적 성분과 조직감의 변화를 살펴본 결과, 식물조직의 변화는 펙틴질의 성질에 크게 영향을 받고 있었으며, 이러한 조직의 변화에 관여하는 요인들은 소금의 종류 및 농도, 절임시간, 온도, 예열처리, 염혼합물, 효소, 젓갈, 마늘첨가량 등이 복합적으로 작용하고 있었다.

The purpose of this study was to evaluate the relation of nutrients intake and copper status between nonvegetarian female college students and lacto-ovo-vegetarian female college students. The height, weight and serum copper concentrations were determined. Food nutrients analysis procedure was made by computer using food composition table. The results was summarized as followed; 1) Mean values of weight & height were respectively 53.58±1.68㎏·157.05±1.43㎝ in nonvegetarians and 51.23±1.45㎏·156.65±1.24㎝ in lacto-ovo-vegetarians. 2) The average intakes of protein, fat, carbohydrate, fiber, Ca, P, Fe and Vit. C were above the RDA in the two groups, but those of calories was below the RDA in non-vegetarians. Especially, fiber and iron intakes were significant in the two groups(p<0.01, p<0.05). 3) The percentage of iron absorption was 7.64% in nonvegetarians and 5% in lacto-ovo -vegetarians. 4) Mean serum copper values of nonvegetarian and vegetarian were 107.08±14.39㎍/100㎖ and 113.31±20.86㎍/100㎖, respectively.

본 연구의 목적은 국내 대학생들의 학업동기신념 프로파일 유형을 탐색하고 프로파일 집단에 따라 수업 참여도, 학업관련 문제 행동, 학업 부정행위 등에 어떠한 차이가 나타나는지를 확인하는 것이다. 이를 위해 한국교육종단연구 8차년도 조사 참가자 중 국내 4년제 대학에 재학 중인 2,447 명을 분석 대상으로 하였다. 잠재프로파일분석(LPA) 결과, 5개의 프로파일 모형을 최종 모형으로 선택하였으며, ‘높은 효능감과 높은 숙달목표형’, ‘높은 성취목표형’, ‘중간동기형’, ‘낮은 효능감과 낮은 수행목표형’, ‘매우 낮은 수행목표형’으로 각 프로파일을 명명하였다. 학업동기신념 프로파일에 따라 대학생의 수업참여도, 학업관련 문제 행동, 학업 부정행위에서 유의한 차이가 나타났다. ‘높은 효능감과 높은 숙달목표형’은 모든 학업관련 행동에서 가장 적응적인 결과를 보였으며, 성취 목표 수준이 낮은 집단들은 수업참여도가 낮고, 학업관련 문제 행동과 학업부정행위를 더 많이 하는 것으로 나타났다. 한편, 숙달목표와 수행목표가 모두 높은 ‘높은 성취목표형’은 숙달목표만 높고 수행목표가 낮은 ‘높은 효능감과 높은 숙달목표형’에 비해 수업 중 문제행동과 학업부정행위 정도가 유의하게 높게 나타났다. 마지막으로 본 연구 결과가 대학교육에 주는 시사점을 논의하였다.

According to the revised version of Waste Control Act to enter into force in 2017, Wastes could only be recycled assuming that the use of recycled wastes is safe for the environment and human health by environmental safety assessment. Even before this revision of the law, inorganic sludges could have been recycled as alternative materials for filler and cover materials by mixing with soil. However, in case of inorganic sludge from car-washing facilities, the revised law provides that the waste has to be landfilled. To assess the possibility of recycling this waste, we investigate the characteristics of the generation and concentration level of hazardous substances and evaluate the safety of recycling this material to assess whether this process meets the environmental standards. We obtained a total of eight sludge samples from car-wash shops, such as those in gas stations, car-repair shops and car-wash facilities. According to the results of leaching tests, most of the samples(8) fell under the detection limit and thus could be legally treated as general waste. However, in the results of contents some heavy metals, such as hexavalent chromium, lead, copper and zinc, exceeded the standards for soil contamination. We can conclude that the recycling of inorganic sludge from car-wash facilities could cause pollution in soil media when recycled and should not be recycled for filler and cover materials.
