  • This survey was carried out to investigate the utilization situation of fire-wood boiler by the questionnaire and personal interview on rural and mountain households of Gangwon province from 1998 to 2005. The questionnaire include 7 questions on installation, 7 questions on fuel, 3 questions on use, and 3 questions on improvement. Each question was analyzed by percentage to investigate the use situation. This survey indicated that the general problems in use of fire-wood boiler are fuel purchase, collection and transportation, that the development of the household heating boiler using wood-based forming fuel which is cheap, small volume, easy handling, convenient purchase and high heat efficiency could be an alternative to improve the problems and that the continuous expansion of the supply of fire-wood boiler can prevent the devastation of forest through the regulation of imprudent fuel supply. Although the financial aid plan on the installation of fire-wood boiler is in active, many petty households in rural and mountain areas lose a chance to install the fire-wood boiler due to the unsatisfactory information. Thus, it will be desirable for municipal government to prepare the information plan to offer the equal chance and condition to all households in rural and mountain areas and to increase the financial aid for the continuous supply of fire-wood boiler.

  • Purpose: The purpose of this study was to identify the relationship between Health Locus of Control(HLOC) and Health Promoting Behaviors(HPB) in the nursing college students. Method: Data were collected by the structured questionnaires from 485 nursing students in Gwangju. Data were analyzed by using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient and Simple regression. Result: The mean score for the HLOC of the nursing students was Internal: 23.858, Powerful others: 17.619, Chance: 15.076. The total mean score for HPB was 2.45(range 1-4). The highest score on the subscale was self-actualization(M=2.914), and the lowest was health responsibility(M=1.905). The score between HPB and HLOC-internal(r=.302, p=.000), HLOC-powerful others (r=.329, p=.000), HLOC-chance(r=.146, p=.001) showed a significantly positive correlation. By means of simple regression analysis, HLOC explained 14.3% of HPB. Conclusion: This study suggests that HLOC accounted for 14.3 % of HPB in the nursing college students.

  • To develop and improve as the finest foodservice industry, it has to secure the best team organized by the most satisfied employees. It is very important for foodservice industry to have the organization efficiency and study all kinds of factors to be influenced by several conditions. This study was focused on some matters to achieve the foodservice industry's business goal as well as to satisfy the employees. 1, the writer, set up four hypotheses for the examination. First, there will be not an interrelation between the employee's satisfaction and sex, age, marriage, educational background, and eager level. Second, there will be not an intreation between the employee's satisfaction and work period, position, department and major. This study could get some result from the analysis suggested by the above hypotheses. The following are the further explanation including some outstanding feature from the analysis based on the human resource: first for the category about the level of job satisfaction evaluated by the census, foodservice industry employee's job satisfaction depends upon the atmosphere in which employes could enjoy their work. Even the promotion chance can be made in the environment of creative and active working condition. Finally, the promotion chance can be realize not through the employee's attitude assuming the motivation factor to be difference from hygiene factor, but through keeping their work carried out in various activity.

  • Ginseng, the root of Panax ginseng C.A. Meyer, is well-known oriental herbal medicine. The number of paper reporting the effects on its physiological, pharmacological, and behavioral effects has been increased every year, since ginsenosides isolated from ginseng are known to be biologically active components. This brief review summarizes some of new findings from recently published papers on ginsenosides or ginseng saponins. Therefore, this paper includes the various effects of ginsenosides on neuronal cell growths, on behavior of experimental animals, on enzyme activities, on the release and uptake of neurotransmitters, on neuronal cell excitability, on the motility of intestine, on antitumor activity, on cardiovascular system and metabolism. In spite of various effects of ginsenosides on various cells or organs, it is still to date impossible for one to clearly explain the exact mechanism on the action of ginsenosides. However, in this article I will discuss several papers providing possible explanations on the physiological and pharmacological actions including signal transudation pathway of ginsenosides. The elucidation of the exact mechanism of ginsenosides on cellular or molecular level will not only give us a chance to explain why people have used ginseng as an elixir of life for several thousands of year but also give us a crucial chance to apply ginseng to modern medicine.

  • This short paper considers the situation where an environmental policy could play a source of an exogenous background risk at an individual's wealth and analyzes the effect of such a background risk on the individual's decision making in a simple chance-improving model. Our analysis shows that risks at initial wealth generated by an environmental policy could be regarded as an exogenous background risk in many cases and that such a risk makes a risk averse person behave more risk aversely in some restricted decision making situations. A policy maker considering an environmental policy which would affect individuals' initial wealth should take into account that the environmental policy could affect an individual's seemingly irrelevant economics decisions via his or her wealth.

  • These days, there are many applications using neural networks as parts of their system. On the other hand, adversarial examples have become an important issue concerining the security of neural networks. A classifier in neural networks can be fooled and make it miss-classified by adversarial examples. There are many research to encounter adversarial examples by using denoising methods. Some of them using GAN (Generative Adversarial Network) in order to remove adversarial noise from input images. By producing an image from generator network that is close enough to the original clean image, the adversarial examples effects can be reduced. However, there is a chance when adversarial noise can survive the approximation process because it is not like a normal noise. In this chance, we propose a research that utilizes high-level representation in the classifier by combining GAN network with a trained U-Net network. This approach focuses on minimizing the loss function on high representation terms, in order to minimize the difference between the high representation level of the clean data and the approximated output of the noisy data in the training dataset. Furthermore, the generated output is checked whether it shows minimum error compared to true label or not. U-Net network is trained with true label to make sure the generated output gives minimum error in the end. At last, the remaining adversarial noise that still exist after low-level approximation can be removed with the U-Net, because of the minimization on high representation terms.

  • This essay examines the first-generation Korean American writer, No-Yong Park's falsehoods about his ethnic identity to suggest how and why he passed for Chinese, and to explore the political, anti-Japanese implications of these actions. The essay first identifies erroneous information circulating about his biographical background, presents some other materials that help us better understand the context in which he forged his Chinese identity, and then examines how he represented himself as Chinese in his published works. I would argue that Park's self-identification as Chinese was a resulting outcome of his naturalization caused by the Japanese colonial power in Korea and also one of his surviving strategies in the racist environment within American society. Looking at some of his works-including Making a New China (1929), An Oriental View of American Civilization (1934), Chinaman's Chance: Autobiography (1940)-and examining how he represented Korea and its people reveal how he tried to raise voice for them. By doing so, this essay illuminates Park's resistance to Japan's colonial discourse and power in Korea while revealing his lifetime passing as Chinese-far from his refusal to belong to the Korean community, or to acknowledge being Korean.

  • Political connections may facilitate firms' exporting activities, particularly in developing countries, because politically connected firms may be more likely to receive informational and financial support, allowing them to overcome barriers to export. We test this hypothesis using a unique, firm-level dataset from traditional apparel and textile clusters in the Red River Delta Region in Northern Vietnam. We find that political connection of certain types increases the chance of receiving valuable information or financial support from the government. Moreover, those firms that have access to government information have higher chances of being direct exporters. However, firms that receive financial support from the government are not necessarily engaged in exporting activities. Although politically connected firms are more willing to export, they do not necessarily engage in more exporting activities than firms without such connections. These results suggest that the misallocation of information and financial resources to politically connected but insufficiently productive firms leads to a failure to promote exporting activities. In contrast, political connection increases the chance of importing materials and parts, possibly because high productivity is necessary for exporting, but not for importing.

  • A stochastic programming model for river water quality management was developed. River water quality, river flow, quality and flowrate of the wastewater treatment plant inflow were treated as random variables in the model. Withdrawal for water supply and submerged weir reaeration were included in the model itself. A probabilistic model was formulated to compute the expectation and variance of water quality using Streeter-Phelps equation. Chance constraints of the optimization problem were converted to deterministic equivalents by chance constrained method. Objective function was total annual treatment cost of all wastewater treatment plants in the region. Construction cost function and O & M cost function were derived in the form of nonlinear equations that are functions of treatment efficiency and capacity of treatment plant. The optimization problem was solved by nonlinear programming. This model was applied to the lower Han River. The results show that the reliability to meet the DO standards of the year 1996 is about 50% when the treatment level of four wastewater treatment plants in Seoul is secondary treatment, and BOD load from the tributary inflows is the same as present time. And when BOD load from Tanchon, Jungrangchon, and Anyangchon is decreased to 50%, the reliability to meet the DO standards of the year 1996 is above 60%. This results indicated that for the sake of the water quality conservation of the lower Han River, water quality of the tributaries must be improved, and at least secondary level of treatment is required in the wastewater treatment plants.

  • A total of 178 patients with primary lung cancer who had undergone complete resection of the tumor in combination with complete mediastinal lymphadenectomy were reviewed at the Department of Thoracic and Cardiovascular Surgery of Yonsei Medical Center from January 1980 through July 1989. Materials; 1. There were 45 men and 33 women ranging of age from 25 to 78 years with a mean age of 55.4 years. 2. Histological types were squamous carcinoma in 115 cases [64.6%] adenocarcinoma in 42 cases [23.6 %], bronchioloalveolar carcinoma in 9 cases [5.1%], large cell carcinoma in 8 cases [4.5 %] and small cell carcinoma in 4 cases [2.2%] Results were summarized as follows: 1. The size of primary tumor was not directly proportional to the frequency of mediastinal lymph node metastasis. [P =0.0567] 2. The histologic types of the primary tumor did not related to the incidence of mediastinal lymph node metastasis. [P >0.19] 3. The chance of mediastinal lymph node metastasis in the case with lung cancer located in right middle lobe[31.8%, N=22] and left lower lobe [31.4%, N=32] were the highest and the lowest was the one located in right lower lobe, while over all incidence of mediastinal lymph node metastasis in this series was 25.4 % [N=55]. 4. The rate of mediastinal lymph node metastasis without evidence of regional and hilar lymph node metastasis was 13%. [N=23] The chance of mediastinal lymph node involvement without N1 lymph node metastasis was 16.3 % [N=17] in both upper lobes and 8.2 % [N=6] in both lower lobes. It was statistically significant that the tumors in the upper lobes had greater chance of the mediastinal lymph node metastasis without N1 than the tumors in the lower lobes. 5. In this series majority of the patients with lung cancer the mediastinal lymph node metastasis from the tumor in each pulmonary lobes usually occurs via ipsilateral tracheobronchial and paratracheal lymphatic pathway. Especially the lung cancer located in lower lobes can metastasize to subcarinal, paraesophageal and inferior pulmonary ligamental lymph node through the lymphatic pathway of inferior pulmonary ligament. It can be speculated that in some cases of this series otherwise mediastinal lymph node metastasis can also occur with direct invasion to the parietal pleura and to the mediastinal lymph node via direct subpleural lymphatic pathway .
