The Ministry of Agriculture, Forestry and Fisheries prepared the sixth industrialization certification system to increase the added value in the agricultural sector, but it is a bit hard to judge that the system has been in the stage of creating sufficient added value. In particular, because of the Fourth Industrial Revolution, there is a significant change in all industry sectors, including innovation in technology, and the change of perception among the society members is being rapidly changed toward the corporate sector's social role. Thus, we surveyed companies that received the sixth industrialization enterprise certificate to address this phenomenon and find clues on how to be competitive. We selected 800 companies certified by the Ministry of Agriculture, Forestry and Fisheries as sixth industrialization enterprises as our study samples. Among them, we subjected 275 respondents to a final analysis upon eliminating incomplete responses. The result of the study revealed that entrepreneurship, including autonomy that reflects the characteristics of the certified companies, had a significant positive impact on economic value. Moreover, with the size of the companies certified as the sixth industrialization enterprise and the industry trend toward the innovative Fourth Industrial Revolution considered, the strategic orientation including the customer orientation to intensively focus on customer needs and the technology orientation to accept technology as a competitive sector even in the agricultural industry was found to have a significant positive effect on economic value. Strategic orientation demonstrated a significant positive effect on social value. Entrepreneurship demonstrated a significant positive effect on economic values but did not significantly affect the social value. Lastly, while strategic orientation has demonstrated that no mediation effect resulted due to a high direct effect between entrepreneurship and economic value, a complete mediation effect occurred between entrepreneurship and social value. Based on this study, if the companies that received the sixth industrialization enterprise certificate are equipped with not only entrepreneurship but also strategic orientation for customer-oriented thinking and response to technological changes, they can become an influential element in creating not only economic value but also social value, which is emphasized as an element of sustainability.

The wetland ecosystem is a complex products of various erosion force, accumulation as water flows, hydrogeomorphic units, seasonal changes, the amount of rainfalls, and other essential element. There is no single, correct, ecologically sound definition for wetlands because of the diversity of wetlands and the demarcation between dry and wet environments occurs along a continuum, but wetland plays various ecosystem functions. Despite comprehensive integration through classification and impact factors there is still lacking in systematic management of wetlands. Classification system developed by the USFWS(1979) is hierarchical progresses from systems and subsystems at general levels to classes, subclasses, dominance types, and habitat modifiers. Systems and subsystems are delineated according to major physical attributes such as tidal flushing, ocean-derived salts, and the energy of flowing water or waves. Classes and subclasses describe the type of substrate and habitat or the physiognomy of the vegetation or faunal assemblage. Wetland classes are divided into physical types and biotic types. For the wise management of wetlands in Korea, this study was carried out to examine methodology of USFWS classification system and discuss its application for Korean wetland hydrogeomorphic units already known. Seven wetland types were chosen as study sites in Korea divided into some different types based on USFWS system. Three wetland types belonging to palustrine system showed no difference between Wangdungjae wetland and Mujechi wetland, but Youngnup of Mt. Daeam was different from the former two types at the level of dominant types. This fact means that setting of classification system for management of wetland is needed. Although we may never know much about the wetland resources that have been lost, there are opportunities to conserve the riches that remain. Extensive inventory of all wetland types and documentation of their ecosystem functions are vital. Unique and vulnerable examples in particular need to be identified and protected. Furthermore, a framework with which to demonstrate wetland characteristics and relationships is needed that is sufficiently detailed to achieve the identification of the integrity and salient features of an enormous range of wetland types.

The purpose of this study is to examine the chracteristics of the location of Zen Buddhist temples which are the Nine-Mountain Sects of Zen(九山禪門) from feng-shui perspective. A large number of temples have been built for about 1600 years since Buddhism had influenced on Korea. They have been built nationwide in different times by different sects of Buddhism. The pattern of location of Buddhist temples is different according to background of the times (political, economic, cultural aspect) and of tenet(difference in sects of Buddhism) when the temples were built. But the general location of Korean Buddhist temples is in accordance with feng-shui theory. Feng-shui is a traditional geographic thought in China and Korea. It is necessary to understand feng-shui in order to understand Korean landscape and cultural geography. It had given a tremendous impact on Korean landscape through choosing site of cities, settlements, houses, mounments, temples, pagodas, and so on. Before feng-shui was prevailing in Korea, Buddhist temples were mostly built on sacred place which was connected with folk beliefs. In the case of the late Silla Dynasty when Zen Buddhism was prevailing, feng-shui became popular and many. temples were built in accordance with feng-shui. The typical examples are found in the site of Nine-Mountain Sects of Zen temples. The interpretation of geomantic site of Nine-Mountain Sects of Zen temples will show us how feng-shui was applied to and reflected in the Korean peninsula. In Zen Buddhism, feng-shui was applied to the choice of the temple site. Also feng-shui theory was usually used to choose the site of stupa(Budo) where the remains of the founder of sect. In this study, I will interpret the geomantic characteristics of Nine-Mountain Sects of Zen temples. The geomantic interpretations of the temples are as follow. 1. The temples are located at the foot of a hill with surrounding mountains and a watercourse in front. Feng-shui texts often describe it as an ideal site. This geomantic situation is well equipped with natural drainage; protection from cold wind from the north or evil spirits; a good view with open space to the front; protection from unnecessary weather damage; and security and protection from strangers and invaders. 2. The sitting and facing direction of the temples correspond to the oncoming dragon's direction. 3. Many feng-shui texts discuss the types of Sa(surrounding mountains) in detail and morphologically describe them with certain animate and inanimate auspicious objects. In case of Nine-Mountain Sects of Zen temples, the geomantic landscape of these can be compared to auspicious objects. This is morphological marker for the description of configulation features of these temples. 4. Most auspicious places are not perfect, but the shortcomings can be overcome by many means. We can observe modification of landscape for the purpose of fulfilling the geomantic harmony of the temple.

From December 1989 to February 1993, 108 patients with Non-Small Cell Lung Cancers(NSCLC) were studied retrospectively to evaluate radiotherapeutic significance of serum levels of NSE. We considered elevated serum neuron specific enolase(S-NSE) level as one of the neuroendocrine features in NSCLC. Histopathologic evaluation revealed 86 squamous cell carcinomas, 11 adenocarcinomas.3 large cell carcinomas, 3 mucoepidermoid carcinomas, and 5 unknown pathology. Eight Patients had stage 1,40 stage IlIA, and 60 stage lIIB.S-NSE level greater than 15 ng/ml was considered as elevated, and below this considered as normal. All patients recieved radiotherapy as primary treatment modality. The responders to radiotherapy had significantly higher mean S-NSE level than non-responders (28.5 ng/ml vs 20 ng/ml, p=0.01). Overall 2-year survival rate(YSR) was 23.6$ \% $. According to radiotherapy response, 2 YSR for Patients with CR, PR, and NR were 39.2$ \% $, 28.6$ \% $, and 6.2$ \% $ respectively(p=0.001). 2 YSR for patients with elevated and normal S-NSE were 14.6$ \% $ and 31.7$ \% $(p=0.02). The patients with NR showed no difference in survival according to S-NSE level. When we considered all patients, S-NSE level showed no significant impact on response. But for squamous cell carcinomas alone, patients with elevated S-NSE had more responders(80$ \% $ vs 61$ \% $, p=0.05). There was no correlation between tumor characteristics and S-NSE level. But the patients with elevated S-NSE had more patients with higher nodal stage, Based on our and other datas, NSCLC with neuroendocrine features have different response to treatment and clinical behavior compared to other NSCLC. Thus, this subgroup may need different treatment modality, and S-NSE level may have prognostic significance.

Objective : This study was aimed to investigated the correlation between the stroke incidence by day of the week and risk factors in acute stroke patients. Methods : From October in 2005 to October in 2007, 673 acute stroke patients wereincluded. Patients were hospitalized within 14 days after the onset of stroke in DongGuk University International Hospital, Kyungwon University In-cheon Oriental Medical Hospital or the Department of Cardiovascular and Neurologic Diseases (Stroke Center), Kyung Hee University Oriental hospital. We investigated general characteristics, stroke types, age group, educational backgrounds, medical history, lifestyle (the impact of stress, exercise, smoking and drinking) and Sasang constitution according to the stroke incidence by day of the week. Results : After examining each participants with day of the week, the order of days by incidence was Monday, Wednesday, Sunday, Saturday, Tuesday, Thursday and Friday respectively. Monday and Tuesday showed the highest ratio. As the aspect of demographic data of subjects, the group under 55 years and from 55 years to 70 years showed the highest ratio on Monday. In the group between 25 years to 55 years, the ratio, by the classification of actual productive age, was statistically higheron Monday. In addition, the ratio showed statistically higherby educational background, from elementary school to high school and over high school. In regard tothe medical aspect, incidence of cerebral hemorrhage showed higher ratio on Sunday, and incidence of brain infarction was higheron Monday. However, there was no difference of the past history between the two groups. With regard tothe aspect of lifestyle of subjects, the group with huge stress before the incidence of stroke showed a higher ratio of stroke incidence on Monday. Participants who didn't exercise regularly and participants who didn't smoke or drink showed higher ratio of stroke incidence on Monday. However, this was not important statistically. In regard to the aspect of Sasang constitution, Soeumin showed the highest ratio of stroke incidence on Wednesday, Taeuminon Monday, and Soyangin on Saturday and Monday. Conclusion : According to these results, several cardiovascular risk factors affect stroke incidences on Monday. Further studies will be needed to help understand the correlation between stroke incidence by day of the week and risk factors in acute stroke patients.

The advent of the Internet and related Web technologies has created an easily accessible link between a firm and its customers, and has provided opportunities to a firm to use information technology to support supplementary after-sale services associated with a product or service. It has been widely recognized that supplementary services are an important source of customer value and of competitive advantage as the characteristics of the product itself. Many of these supplementary services are information-based and need not be co-located with the product, so more and more companies are delivering these services electronically. Net-based customer service, which is defined as an Internet-based computerized information system that delivers services to a customer, therefore, is the core infrastructure for supplementary service provision. The importance of net-based customer service in delivering supplementary after-sale services associated with product has been well documented. The strategic advantages of well-implemented net-based customer service are enhanced customer loyalty and higher lock-in of customers, and a resulting reduction in competition and the consequent increase in profits. However, not all customers utilize such net-based customer service. The digital divide is the phenomenon in our society that captures the observation that not all customers have equal access to computers. Socioeconomic factors such as race, gender, and education level are strongly related to Internet accessibility and ability to use. This is due to the differences in the ability to bear the cost of a computer, and the differences in self-efficacy in the use of a technology, among other reasons. This concept, applied to e-commerce, has been called the "e-commerce divide." High Internet penetration is not eradicating the digital divide and e-commerce divide as one would hope. Besides, to accommodate personalized support, a customer must often provide personal information to the firm. This personal information includes not only name and address, but also preferences information and perhaps valuation information. However, many recent studies show that consumers may not be willing to share information about themselves due to concerns about privacy online. Due to the e-commerce divide, and due to privacy and security concerns of the customer for sharing personal information with firms, limited numbers of customers adopt net-based customer service. The limited level of customer adoption of net-based customer service affects the firm profits and the customers' welfare. We use a game-theoretic model in which we model the net-based customer service system as a mechanism to enhance customers' loyalty. We model a market entry scenario where a firm (the incumbent) uses the net-based customer service system in inducing loyalty in its customer base. The firm sells one product through the traditional retailing channels and at a price set for these channels. Another firm (the entrant) enters the market, and having observed the price of the incumbent firm (and after deducing the loyalty levels in the customer base), chooses its price. The profits of the firms and the surplus of the two customers segments (the segment that utilizes net-based customer service and the segment that does not) are analyzed in the Stackelberg leader-follower model of competition between the firms. We find that an increase in adoption of net-based customer service by the customer base is not always desirable for firms. With low effectiveness in enhancing customer loyalty, firms prefer a high level of customer adoption of net-based customer service, because an increase in adoption rate decreases competition and increases profits. A firm in an industry where net-based customer service is highly effective loyalty mechanism, on the other hand, prefers a low level of adoption by customers.

As managing customer relationship gets more important, companies are strengthening information service using multi-channels to their customers as a part of their customer relationship management (CRM) initiatives. It means companies are now accepting such information services not as simple information -delivering tools, but as strategic initiatives for acquiring and maintaining customer loyalty. In this paper, we attempt to validate whether or not such various information services would impact on organizational performance in terms of CRM strategy. More specifically, our research objective is to answer the next three questions: first, how to construct the instruments to measure not information quality but information service quality?; second, which attributes of information service quality can influence corporate image and customer loyalty?; finally, does each information service type have unique characteristics compared with others in terms of influencing corporate image and customer loyalty? With respect to providing answers to those questions, the previous studies had been limited in that those studies failed to consider the variety of types of information service or restricted the quality of information service to information quality. An appropriate research model answering the above questions should consider the fact that most companies are utilizing multi channels for their information services, and include the recent strategic information service such as customer online community. Moreover, since corporate information service could be regarded as a type of products or services delivered to customer, it is necessary to adopt the criteria for assessing customer's perceived value when to measure the quality of information service. Therefore, considering both multi-channels and multi-traits may enable us to tell the detailed causal routes showing which quality attributes of which information service would affect corporate image and customer loyalty. As information service channels, we include not only homepage and DM (direct mail), which are the most frequently applied information service channels, but also online community, which is getting more strategic importance in recent years. With respect to information service quality, we abstract information quality, convenience of information service, and timeliness of information service through a wide range of relevant literature reviews. As our dependant variables, we consider corporate image and customer loyalty that both of them are the critical determinants of organizational performance, and also attempt to grasp the relationship between the two constructs. We conducted a huge online survey at the homepage of one of representative dairy companies in Korea, and gathered 367 valid samples from 407 customers. The reliability and validity of our measurements were tested by using Cronbach's alpha coefficient and principal factor analysis respectively, and seven hypotheses were tested through performing correlation test and multiple regression analysis. The results from data analysis demonstrated that timeliness and convenience of homepage have positive effects on both corporate image and customer loyalty. In terms of DM, its' information quality was represented to influence both corporate image and customer loyalty, but we found its' convenience have a positive effect only on corporate image. With respect to online community, we found its timeliness contribute significantly both to corporate image and customer loyalty. Finally, as we expected, corporate image was revealed to provide a great influence to customer loyalty. This paper provides several academic and practical implications. Firstly, we think our research reinforces CRM literatures by developing the instruments for measuring information service quality. The previous relevant studies have mainly depended on the measurements of information quality or service quality which were developed independently. Secondly, the fact that we conducted our research in a real situation may enable academics and practitioners to understand the effects of information services more clearly. Finally, since our study involved three different types of information service which are most frequently applied in recent years, the results from our study might provide operational guidelines to the companies that are delivering their customers information by multi-channel. In other words, since we found that, in terms of customer loyalty, the key areas would be different from each other according to the types of information services, our analysis would help to make decisions such as selecting strengthening points or allocating resources by information service channels.

A new silicate coating technology was developed which reduces the impact of dust and loosening during seeding compared to existing silicate-coatings (Seed/Si/Zeolite), and therefore can lower the production costs of rice cultivation. In this method, 100 g of rice seed is coated with 18 mL of liquid silicic acid and then dressed with a mixture containing 80 g of dolomite and 5 g of iron. To determine the most effective method of application and ensure that seedlings developed healthily, a series of experiments were carried out. Infected seeds scattered in seedling boxes and pots (soil and hydroponic) were coated dry, without disinfection. In comparison to the seed which were not treated with the silicate-coating, the new seed (A) were 1.84 times heavier in weight, and were also improved in terms of coating strength and coating color. Compared to the seedlings grown from the non-coated seed, those grown from the new silicate-coated seed were of significantly higher quality (weight/length) and had erect, dark greenish leaves, which are ideal plant characteristics. This was most likely due to increased silicate uptake. The symptoms of bakanae disease in the non-coated seed peaked after 38 days to 54.2%, whereas the control value was 68.8% in the new silicate-coated seed (A). In the infected seedlings grown from the new silicate-coated rice seed, subnormal macro-conidia, namely, a sickle shape spore without a septum; a straight oblong shape spore without a septum and with a thick cell wall; and inter-septal necrosis of a normal spore were detected. It is believed that the strong alkalinity of silicic acid have acted as unfavorable conditions for pathogenicity. In seedlings grown from the new silicate coated rice seed under hydroponic conditions without nutrients, normal root activity and growth was maintained without leaf senescence. Therefore, it was possible to reduce the rate of fertilization. In the future, a new silicate-coated rice seed was required for the study of minimal nutrition for anti-aging of seedlings.

The objectives of this study were to evaluate the physico-chemical water quality, trophic and tolerance guilds in the control ($C_o$) and impacted streams of the abandoned mine, along with the ecological health, using a multimetric health model and physical habitat conditions of Qualitative Habitat Evaluation Index (QHEI), during the period of three years, 2005~2007. Also, eco-toxicity ($EE_t$) enclosure tests were conducted to examine the toxic effects on the outflows from the mine wastewater, using the sentinel species of Rhynchocypris oxycephalus, and we compared the biological responses of the control ($C_o$) and treatment (T) to the effluents through a Necropybased Health Assessment Index ($N_b$-HAI). Tissue impact analysis of the spleen, kidney, gill, liver, eyes, and fins were conducted in the controlled enclosure experiments (10 individuals). According to the comparisons of the control ($C_o$) vs. the treatment (T) in physicochemical water quality, outflows from the abandoned mine resulted in low pH of 3.2, strong acid wastewater, high ionic concentrations, based on an electrical conductivity, and high total dissolved solid (TDS). Physical habitat assessments, based on Qualitative Habitat Evaluation Index (QHEI) did not show any statistical differences (p>0.05) in the sampling sites, whereas, the $M_m$-EH model values in a multimetric ecological health ($M_m$-EH) model of the Index of Biological Integrity (IBI), using fish assemblages, were 16~20 (fair condition) in the control and all zero (0, poor condition) in the impacted sites of mine wastewater. In addition, in enclosure eco-toxicity ($EE_t$) tests, the model values of $N_b$-HAI ranged between 0 and 3 in the controls during the three years, indicating an excellent~good condition (Ex~G), and were >100 (range: 100~137) in the impacted sites, which indicates a poor condition (P). Under the circumstances, organ tissues, such as the liver, kidney, and gills were largely impaired, so that efficient water quality managements are required in the outflow area of the abandoned mine watershed.

The occurrence of natural radioactive materials such as uranium and radon-222 in groundwater was examined with hydrogeochemistry and geology at ○○ village in the Yongin area. Two rounds of 19 groundwater and 5 surface water sampling were collected for analysis. The range of pH value in groundwaters was 5.81 to 7.79 and the geochemical types of the groundwater were mostly Ca(Na)-HCO₃ and Ca(Na)-NO₃(Cl)-HCO₃. Uranium and radon-222 concentrations in the groundwater ranged from 0.06 to 411 μg/L and from 5.56 to 903 Bq/L, respectively. Two deep groundwaters used as common potable well-water sources exceeded the maximum contaminant levels of the uranium and radon-222 proposed by the United States Environmental Protection Agency (US EPA). Three groundwater samples from residential areas contained unsuitable levels of uranium, and 12 groundwater samples were unsuitable due to radon-222 concentrations. Radioactive materials in the unsuitable groundwater are naturally occurring in a Jurassic amphibole- and biotite-bearing granitic gneiss. High uranium and radon-222 groundwater concentrations were only observed in two common wells; the others showed no relationship between bedrock geology and groundwater geochemical constituents. With such high concentrations of naturally occurring radioactive materials in groundwater, the affected areas may extend tens of meters for uranium and even farther for radon-222. Therefore, we suggest the radon-222 and the uranium did not originate from the same source. Based on the distribution of radon-222 in the study area, zones of higher radon-222 concentrations may be the result of diffusion through cracks, joint, or faults. Surface radioactivity and uranium concentrations in the groundwater show a positive relationship, and the impact areas may extend for ~200m beyond the well in the case of wells containing high concentrations of uranium. The highest uranium and thorium concentrations in rock samples were detected in thorite and monazite.
