This study was carried out to determine the effect of fruit-set position and number of fruit set per plant on yield and quality including netting in "Super VIP" melon cultivated in spring season. 1) In training system of one fruit per plant, index of netting was acceptable, regardless of the node position of fruit-set. The higher node order of fruit set was, the heavier, longer, bigger in diameter the fruit set was, and the thicker the flesh was. However, soluble suger content and storability was decreased with increased node order. 2) In training system of two fruit per plant, the higher the fruit-set position in node order was, the better the netting index, fruit quality including fruit weight, length, diameter, and thickness of flesh were, but there was no difference in storability. 3) Fruits produced by one-fruit-per-plant training were superior to those produced by two-fruit-per-plant training in maker quality including netting, sugar content, stcrability. The fruit set on 12th node in one-fruit-per-plant training were the best in market quality. 4) Yield was increased by two-fruit-per-plant training.

With the accumulation of protein and its related data on the Internet, many domain based computational techniques to predict protein interactions have been developed. However, most of the techniques still have many limitations to be used in real fields. They usually suffer from a low accuracy problem in prediction and do not provide any interaction possibility ranking method for multiple protein pairs. In this paper, we reevaluate a domain combination based protein interaction prediction method and develop an interaction possibility ranking method for multiple protein pairs. Probability equations are devised and proposed in the framework of domain combination based protein interaction prediction method. Using the ranking method, one can discern which protein pair is more probable to interact with each other than other protein pairs in multiple protein pairs. In the validation of the ranking method, we revealed that there exist some correlations between the interacting probability and the precision of the prediction in case of the protein pair group having the matching PIP(Primary Interaction Probability) values in the interacting or non interacting PIP distributions.

Is an artificial intelligence robot, a non-human beings newly emerging in the age of technology, a threat to human beings, or a mutual cooperation or ensemble with human beings? The desire to control nature through the use of the power of science and technology is manifested in the fear that humans can annihilate themselves. This study attempts to identify the problems of Cartesian epistemology underlying these questions and fears and to answer these questions based on Merleau - Ponty 's ontological ontology using the Ontology and Latour' s ontology and technological philosophy. The cogito derived from the Cartesian philosophy became the basis of the structure of dichotomous epistemology of 'subjectivity and objectivity' based on human - reason. In the human-centered world, all non-human beings were tools or controls for humans. The problem of the modern people is not only to get help from the natural scientific methods to control the nature including man, but also to think that scientific method is the only way to understand the world. In criticizing this, Merleau-Ponty shows that the body mediates between human beings and non-human beings, and provides a possible ontological basis for the ontology. Merleau - Ponty 's phenomenological methodology and ontology are newly developed by Simondon under the influence of phenomenological philosopher and phenomenology. The relationship between human beings and nonhuman beings by Simondon appears as an ensemble of human and technical objects or a mutual co - operation of human and technical objects. In particular, Latour goes a step further in Simondon and defines all the bodies living in the world as actor-network theory, denying the core concept of modernity. Merleau - Ponty 's phenomenological view can be a new possible basis for the philosophical discussion of the technological age. We will see that the problem itself can be solved by shifting modern fear to a phenomenological attitude.

This study purpose is to discuss critically the conception of history in Hegel and Marx by drawing on Merleau-Ponty's existential theory of history, finishing with concluding remarks. Merleau-Ponty insists that history is always history experienced. This thesis is his own principle in investigating human history. From this perspective, he begins to flesh out problems with history which Hegel and Marx had understood idealistically and materialistically respectively. He criticised that if Hegel grasps history in terms of teleology, he failed to explain the source and origin of historical meaning from which history makes sense. He failed to think that what gives history meaning comes from embodied consciousness. This means that history is not made of dialectical thinking. The thing is different from such an imaginative construal. History as it stands is not like that. It is not running around like Hegelian dialectical thinking. Marx understood historical behavior wrongly when he explained class struggle in terms of productive relations. He disregarded how class was sedimented or embodied in the minds of proletarians. Owing to this, Marx could not suppose that class consciousness is determined not causally or externally but by incarnated experience. It is affected in so far as it is affected by somebody, that is, the worker. At that moment only Class consciousness begins to work. Marx did not catch sight of this hidden fact.

In this study, we wanted to analyze the causes of food poisoning and its major occurrence in September 2018 and analyze the relevance of the HACCP certification system to report the correlation. Based on three-year food poisoning cases and causative substances data, and big data on HACCP certification companies and food poisoning frequency, Hygiene 1: 'Salmonella would have spread through school food processing medium.' Hypothesis 2: The difference in the number of food poisoning cases in the last three years as the number of HACCP certifier increases, the number of food poisoning cases will be verified and the cause of food poisoning in September 2018. Studies show that the food poisoning in September 2018 was caused by salmonella bacteria and that outsourced food provided through school meals was the cause. It was also shown that the expansion of HACCP certification did not significantly contribute to the reduction of food poisoning. Therefore, the management operation measures were proposed as a solution to prevent salmonella and to become HACCP certification that could reduce food poisoning.

농업가뭄에 대한 연구는 주로 가뭄지표의 개선과 제안 등에 초점이 맞추어져 있으며 관개기의 강수량에 중점을 둔 사례가 대부분이다. 그러나 대부분의 논 관개용수는 저수지를 통하여 공급되기 때문에 관개가 시작되는 4월 초순의 저수량은 상당히 중요한 가뭄 대응 요소이다. 이에 따라 가뭄에 대비하기 위해서는 관개가 종료되는 10월부터 이듬해 3월까지 충분한 저수량이 확보될 필요가 있다. 그러나 기후변화에 의해 대부분의 강우가 관개기에 집중될 수 있으며 이에 따라 미래에는 비관개기 동안 충분한 저수량을 확보하는데 어려움이 발생할 수 있다. 이에 본 연구에서는 기후변화에 따른 비관개기의 강수량을 확률기반으로 분석하고, 이를 관개기 필요저수량과 비교하여 저수지의 미래 가뭄 대응 능력을 분석하고자 하였다. 기후변화에 따른 비관개기의 강수량 변화를 분석하기 위하여 RCP(Representative Concentration Pathways) 시나리오를 적용하여 미래 비관개기 동안의 연도별 비관개기 누적강수량을 분석하였다. 과거와 미래시기를 30년 단위로 구분하여 1995s, 2025s, 2055s, 2085s의 비관개기 동안의 비초과확률 10%, 50%, 90%의 강수량을 분석하였다. RCP 4.5 시나리오를 기반으로 모의한 미래강우의 비초과확률 10% 누적강수량 산정 결과에 따르면 주요 곡창지대인 전라남북도는 1995s에는 10월부터 이듬해 3월까지의 누적강수량이 약 215mm 정도로 나타났으나 2025s에는 약 150mm로 줄어드는 것으로 나타났다. 즉, 비초과확률 10%의 강우가 내릴 경우 비관개기 동안에 충분한 저수량의 확보가 어렵게 되고 관개기의 심각한 가뭄을 초래할 수 있었다. 비관개기 누적강수량과 저수량변화의 관개를 모의한 개운저수지와 계룡저수지의 경우 그 관계식은 y=1.442x-198.81, y=5.8105x-752.92와 같이 나타났다. y는 비관개기의 저수량변화를 나타낸 것이고 x는 비관개기의 누적강우량을 나타낸 것이다. 식을 통해 향후 100년 중 비초과확률 10%의 강수를 가정한다면 개운저수지는 관개종료시점의 저수율이 최소 96.93% 이상이여야 다음해 관개시작시점의 저수위가 만수위가 될 수 있었고, 계룡 저수지는 최소 86.84%의 저수위를 만족해야 다음해 관개시작시점의 저수위가 만수위가 될 수 있었다.

The main purpose of this study is to analyze the reform of deadministration of universities in China by the Cooper's 4-dimension of education policy theory. Based on the theory, the reform of deadministration was analyzed in four dimensions(normative, structural, constituent, and technical dimension). First, in the normative dimension, the Chinese university deadministration policy is fully guaranteed by law, and mainly aimed at "modernization of education management system and management ability". Second, in the structural dimension, a highly administrative management paradigm of universities has played an important role during the early stages of higher education development, but it now becomes one of the main obstacle to its further development. However, the Chinese university de-administration policy is a policy that has taken almost 60 years. Therefore, this problem must be solved step by step. Third, in the constituent dimension, although there were some differences in the attitudes towards "the administration" and "the de-administration" of Chinese scholars, university presidents and the public(students), most of them agreed on eliminating "the administration of universities." Fourth, in the technical dimension, Chinese central government and many universities have accumulated many achievements of "the deadministration policies" in management and practice, while some criticisms are heard, either. However, I hope that all reform cases, regardless of their success or failure, will become a model for future administrative reforms.

The final goal of this study was to develop an optimal service scenario to ensure that building occupants can be effectively evacuated from the building within the golden time without extra assistance in preparing and evacuating for fires. In addition, the research was carried out by dividing the current services into fire evacuation and preparedness phases by applying the Double Diamond process in order to find a way to better familiar them as a lifestyle and to always be prepared for fires. For the building occupants and managers, a total of 14 ideas were first suggested, including not only the services of how to evacuate from a fire, but also the life-style service functions associated with fire implementation technology in daily life. The 14 proposed ideas were conducted by the Service quality evaluation and Analytical Hierarchy Process(AHP) from the perspective of the service recipient, and those were finally prioritized from the service provider's perspective, taking into account the cost and practicality of the service provider. The results of this study show that differences in the importance of fire phases considered by stakeholders and the perception of fire generally vary considerably.

In this study, two essential oils (EOs) extracted from Aleriana fauriei and Alpinia galangal were formulated as an emulsifiable concentrate (EC) and a granule. In the evaluation of their acute toxicity on fishes, Cyprinus carpio adults were used and the toxicities were determined in a static condition. The formulations were prepared from the essential oil extracted by three different methods namely steam distillation (SD), solvent extraction (SE) and supercritical fluid extraction (SFE). The acute toxicities were calculated using $LC_{50}$ values. Among EOs, only the EO extracted by solvent showed acute toxicities on carps. Some of the EC, EOs of Aleriana fauriei did not exhibit toxicity, while EOs from Alpinia galangal showed potent acute toxicities on carps. Among the granules, granules formulated with Aleriana fauriei EO extracted by SD method and Alpinia galangal EO extracted by SFE method showed acute toxicities on fishes. Nevertheless, $LC_{50}$ of ECs and granules formulated with all types of EOs in this study was higher than the fish toxicity level III for pesticides suggested by Korea Rural Development Administration. Furthermore, cytochrome P450 1A and glutathione S-transferase were confirmed as biomarkers in carps in response to the exposure to Alpinia galangal EO extracted by SD and SFE method, tracking Alpinia galangal EO in the aquatic environment.

The purpose of this study is to identify the influence of demographic characteristics such as inappropriate lifestyle, stress, and health status among health risk factors of early adolescents according to gender. There is a gender difference in the perception of mental and physical health of early adolescents, and the result can be different in behavior patterns between men and women. This study was conducted to identify the health risk factors as independent variables for early adolescents in Daegu and Gyeongbuk area, and to analyze the determinants of gender (male, female) differences by parents, family environment, friends, academic background, appearance, grade, location, school grades, family situation, and health status as demographic factors. And, the Odds Ratio of the early adolescents was analyzed through logit analysis and the differences according to the influence relationship of each of them were examined. As a result of the analysis, the more the sleep and physical activity, parents, home environment, friends, academic background, and appearance are increased, the more the influence is likely to become on the male students. On the contrary, the rest of the health risk factors can increase, and the threat to the health risk factors is likely to become severe to the female students.Among them, it is necessary to develop a pre-preventive program for early adolescents' health risk factors, provide basic data for practical application in the field, and seek a detailed program according to the gender of early adolescents.
