Objectives: The purpose of this study was to determine whether cardiorespiratory fitness and leisure time physical activity in men screening positive for ADHD were low compared to age- and sex-matched reference values. Methods: 30 college men screening for ADHD were recruited. Data were collected between October 2014 and April 2015. Maximal cycle exercise tests were performed to assess cardiorespiratory fitness and typical 7-day leisure time physical activity was self- reported. Results: Mean cardiorespiratory fitness was 0.94 SD lower than age- and sex-matched reference values. Cardiorespiratory fitness and ADHD symptoms were significantly negatively associated (r= -.39). Leisure time physical activity was 0.3 SD lower than a prior study of 411 college students. A linear regression showed a significant prediction of cardiorespiratory fitness from the combination of ADHD symptoms and leisure time physical activity. Conclusions: Men screening positive for ADHD was characterized by low cardiorespiratory fitness and leisure time physical activity.

獨逸에 있어서 카르테政策은 19世紀 前半 獨逸의 工業化가 이루어진 때부터 시작되어 바이마르共和國, 나치의 執權, 聯合國의 軍政을 거치는 동안 여러 變化가 있었다. 즉, 카르텔政策의 施行初期와 바이마르共和國時代에 있어서는 製約 및 結社의 自由라는 思想的 背景아래 企業間의 카르텔을 原則的으로 企業의 自由에 맡기었고, 나치執權時代에 있어서는 國家의 權力이 企業經營을 支配하게 되어 企業間의 카르텔을 全液的으로 간섭하게 되었다. 戰後에는 占領地法에 의하여 英美式 自由主義經濟原則이 導入되어 獨逸의 카르텔政策도 이를 基礎로 하였으나 1949年 獨逸聯邦共和國이 創建되고, 1957年 現行 競爭制限禁止法(GWB)이 制定되면서부터는 獨自的인.카르텔政策을 펼쳐 나가고 있다. 本論文에서는 먼저 獨遂의 카르텔政策의 施행過程을 時代別로 살펴 본 다음 競爭制限禁止法의 制定經緯와 그 恩想的基本原理, 改定內容등에 관하여 記述하였고, 또한 競爭制限榮止法에 의한 經濟政策이 오늘날 獨逸의 福祉社會形成에 커다란 寄與를 해왔다는 점을 밝히고 있다. 한편 카르텔法의 存在意味와 그 法的 價値는 多樣한 經濟政策과 관련 시키면서 카르텔法의 解釋과 그 適用上의 문제점을 考察하였다. 또한 카르텔法에 있어서 最高規範이라 볼 수 있는 競爭制限禁止法 第1條 등과 관련된 獨逸辨邦大法院의 法解釋과 그 運用에 관하여 살펴보고, 實務想으로 문제되고 있는 企業證와 카르텔廳사이의 關係, 訴訟問題등을 實例를 들어 檢討함으로써 競爭制限禁止法에 있어서의 懸案事項을 다루었다. 끝으로 競爭制限禁止法의 運用方向을 提示함으로써 獨逸에 있어서의·카르텔政策 올바른 方向에 대하여 言及하고 있다.

The study determined the efficiency and performance of the distribution chain of marine capture fisheries in Lucena Fish Port Complex, Lucena City, Philippines. A survey using a pre-tested questionnaire was conducted among 125 respondents consisting of fishermen, traders, truckers, wholesalers and retailers. Simple random sampling was used to identify the fishermen, traders and retailers while complete enumeration was done in the case of truckers and wholesalers. Descriptive, product flow, value chain and cost and return analyses were employed in the study. Based on the performance measures used in the study, including the gross margins computed, the performance of the distribution and transportation system of marine capture fisheries products in Lucena Fish Port Complex can be considered inefficient due to high transportation rates, high spoilage rate, and longer traveling hours than what is expected. The study recommended technology development for improved operations, introduction of the open bidding system to prevent information asymmetry, practice of responsible fishing, key players to assume other roles in the chain, planning ahead the use of alternative roads, ensuring proper management practices, construction of paved roads. securing fishing permits and full utilization of the cold storage facility.

In the field of machining difficult-to-cut materials like titanium or nickel-based alloys, the use of high-pressure cooling lubricantsupply (HPCLS) offers huge potential to significantly increase productivity and process stability. Due to enhanced cooling andlubrication of the cutting zone, tool wear can be decreased which allows higher applicable cutting speeds. Furthermore, processstability can be increased through effective chip breaking and evacuation. Increasing energy prices and legislative frameworkconditions, require energy efficient machine tools and processes. Since additional energy is required to run the high-pressure pump,it has to be determined if the overall process is still energy-efficient due to the increase in productivity resulting in shorter cycle times. In this paper the overall aim is to evaluate the conventional-flood-cooling and HPCLS in terms of economics and energy efficiency. Therefore a case study has been performed in which the energy consumption and production times for machining a rotationallysymmetric jet engine part made of Inconel 718 were compared for both conventional and HPCLS. Furthermore, an ecologicalevaluation has been conducted to determine the advantageousness of the HPCLS. Due to the rising necessity of suppliers to providea product carbon footprint, a methodology for assessing the footprint has been applied.

Studies on the effect of soil moisture, different seasons, harvesting periods and nitrogen application on the nitrate content of radish(Raphanus sativus L. var. niger(Mill.) S. Kerner) were carried out in pot and green house. The results are as follows; The low level of soil moisture leads to an increased nitrate accumulation in radish root. The nitrate content was found to be higher in spring crops and lower in summer ones. It was decreased during harvesting period. The application of nitrogen fertilizer increased the nitrate content in radish root. We found the highest content in petioles with lesser content in roots and leaf blades in that order. The multiple regression analysis and the nutritional value of nitrate content in radish were discussed.

Purpose – The study assessed the influence of some variables relevant to vegetable farmers’ decisions in farm machinery usage. The decision of farmers in using farm machineries is determined by a number of social, technical, environmental and economic factors. Design/Methodology/Approach – The binary logit model was employed to determine the relationship of the predetermined factors on farmers’ use of a single-specific farm machine. Furthermore, the study utilized negative binomial regression to assess the factors influencing the decisions of farmers in using various farm machineries in their farming operations. Findings – Results showed that majority of the farmers still follow traditional farming methods using very limited farm technologies. Farmers face the challenge of optimizing their land use, and this includes their decision whether or not to use farm machineries in their farming operations in order to boost production. Various factors are considered, more than just the cost of technology. Thus, a combination of household-specific, economic, technology, institutional and moderating factors influences the technology adoption decisions of vegetable farmers. Moreover, it was revealed that formal education, household size, household income, cash availability, farm size, access to extension workers, attendance in seminars, trainings and workshops, and on-farm demo participation are all positively related to the probability of farmers’ usage of identified farming machines. Conversely, farming experience, cost of technology, technology triability, credit access, and farm distance to market are all found to be negatively related to the probability of farmers’ usage of farm machineries. Research Implications – Various recommendations were offered to address challenges encountered by farmers in terms of farm machinery usage including changing the farmers’ mindset from a traditional perspective to a market-oriented one via the R.E.S.E.T. model.
