Objectives : The purpose of this research was to examine that effect of Sosang($LU_1$)-Eunbaek($SP_1$) bloodletting was similar to effect of Sa-kwan $LI_4$) and Taechung($LR_3$)> acupuncture on pain and discomfort of acute dyspepsia in upper abdomen. Methods : We divided 36 patients with acute dyspepsia into two groups and treated Group A with Sosang($LU_{11}$)-Eunbaek($SP_1$) bloodletting and Group B with Sa-kwan $LI_4$) and Taechung($LR_3$)> acupuncture. Pain and discomfort in upper abdomen was measured by Visual Analogue Scale(VAS) scores of the two groups before treatment and after 15 minutes to treat. Results : Both group A and B represented effective improvement in VAS of pain and discomfort in upper abdomen. And there was no difference between A group and B group statistically. Conclusions : It is suggested that Sosang($LU_{11}$)-Eunbaek($SP_1$) bloodletting may have similar effect compared with Sa-kwan $LI_4$) and Taechung($LR_3$)> acupuncture on acute dyspepsia treatment.
The purpose of this study was to investigate correlations between entrepreneurial intention and entrepreneurship and entrepreneurial success. For that purpose, the study carried out a survey among the students of Graduate School of Business & Entrepreneurship, the students of small business start-up education, and general people and reviewed the previous studies and literature with a focus on the characteristics and capabilities of entrepreneurial intention. The investigator identified the characteristic factors of entrepreneurial intention including entrepreneurial intention, entrepreneurship, entrepreneurial success, education, and mentor, set a research model and hypothesis for their relations with entrepreneurial success, and empirically analyzed and tested them. The empirical analysis results were summarized as follows: first, entrepreneurial methods and abilities of the variables of entrepreneurial intention turned out to have significant impacts on entrepreneurial success. Second, corporation determination, external factor, and internal factor of the variables of entrepreneurship turned out to have significant effects on entrepreneurial success. Third, re-education after success turned out to be the most influential entrepreneurial education factor on entrepreneurial success, which points to a need for constant education after setting up a business. Fourth, practical entrepreneurial mentors had the greatest influences on entrepreneurial success, being followed by successful entrepreneurial mentors and socially successful mentors in the order. One can have a vision to see a further future of his or her business and promote its growth by forming relationships with those who have more knowledge about the line of business and richer experiences in the field. The subjects overwhelmingly had a positive personality, which suggests that those who try to start a business tend to be positive and considerate of others.
Tribolodon hakonensis(Cypriniformes; Leuciscinae) is anadromous; they are born in freshwater, migrate back to the ocean, then return to their home stream for spawning from mid-March to early-June. Here, five microsatellites were used to assess the level of gene flow among T. hakonensis populations from the Samcheok-Oship Stream, South Korea. The frequencies of dominant alleles across several loci differed between down-and upstream populations divided by several weirs, and pairwise multilocus $F_{ST}$ estimate was significantly high(0.083). However, there were no signs of any loss of genetic variation in the upstream population. Assignment tests of individuals in admixture model(K=2) to a set of baseline samples showed fairly correct assignment to each cluster; all of upstream individuals sere included in the first cluster, while the majority of downstream individuals(65%) comprise the second cluster. These results indicate reduced gene flow between up- and downstream populations but allowing passive downstream drift. It is likely that man-made structures might at least partially be a factor for creating and consolidating the current distribution patterns of genetic variation among T. hakonensis populations in the Samcheok-Oship Stream. This information will assist governing agencies in making informed decisions regarding conservation of anadromous fishes in Korean drainage systems.
Morphine, a $\mu$-receptor agonist, produces strong analgesic effect with some side effects such as nausea, vomiting, urinary retension, somnolence, and respiratory depression. Buprenorphine also provides strong analgesic effects, and hemodynamic changes after continuous infusion of morphine, or buprenorphine-ketorolac combination in gynecologic patients. Analgesic effect was assessed by visual analogue scale(VAS) and Prince Henry scale(PHS). Morphine group, initial 2 mg of bolus morphine was followed by 48 mg/96 ml of continuous infusion. Buprenorphine group, initial 0.1 mg of buprenorphine was followed up with infusion by 2.3 mg/100 ml. Half dose of both initial bolus and maintenance buprenorphine with ketorolac 15 mg for bolus and 60 mg for maintenance were infused in buprenorphine-ketorolac combination group. No significant hemodynamic changes were seen in any of the groups. VAS significantly decreased after 15 minutes of infusion in all three groups, and was significantly lower in morphine group than the other 2 groups, after 60 minutes. PHS was decreased significantly 15 minutes after infusion in the morphine group, and after 60 minutes in two other groups. The incidence of side effects were similar between morphine and buprenorphine groups, but significantly reduced in buprenorphine-ketorolac combination group. We concluded that buprenorphine could be an alternative to morphine for postoperative pain, and smaller dose of buprenorphine could be used if it is combined with ketorolac with less side effects.

The purpose of this study is to clarify the reason of the change of production-and-marketing system and of the regional division. The data for this study were collected by administering interviews with people engaging in hemp fabric industry: namely, craftsmen and managers in the production and marketing of "hemp fabric" handcraft. The summary of this study is as follows: First, the hemp fabric industry is a main subsidiary business of agriculture in Andong. The process of making hemp fabric heavily depends on manual labor. The process is divided into five stages: namely, cultivating hemp, pre-reeling, reeling, weaving, and colouring. Second, Andong "hemp fabric" handicrafts industry had been continuously growth until the late 1960s. During the period of Japan colonization, it was under boom condition: while the other traditional fabric industries were declined. In the 1970s, the decrease of the demand of hemp fabric was the result of mass production of substitute goods on factory system: while, in the 1980s, the growth of per capital income play an important role in bringing about the increased demand of hemp fabric. Third, in the 1980s. production-and-marketing system was changed as the result of the effort to improve the quality and the process, the advanced age of craftsmen, and the weak function of existing marketing systems. The social division of labor within the district is well developed between cultivating hemp, reeling and weaving. The social division of labor is also found in the partly process of handcratfs, and between the production and marketing. The social division of labor between production and marketing is not strongly developed to establish a reliable enterprise that develops a new product and opens a new market. Fourth, the spatial boundary of the production of hemp fabric handcrafts becomes limited into a special region based on the regional specialization of hemp cultivating and the differentiation of utilization of labor.

The introduction of exotic fish species may reduce the number of native fish species and disturb the aquatic ecosystem. Therefore, measures to block and manage fish species are required. Accordingly, a fish species blocking system using bubbles was developed in this study to block exotic fish species. An experimental channel was produced and the possibility of blocking such exotic fish species was evaluated. The bubble generator is a system that produces a bubble curtain by generating air with an air compressor that blocks fish species. Bluegill, which is an exotic fish species in the country, was tested with this generator. The size of bluegill was between 0.10 m and 0.15 m and the depth of water was maintained at 0.70 m. The flow velocity of the experiment channel was classified into 3 levels (0.20 m/s, 0.10 m/s, and 0.05 m/s) considering the natatorial ability of the fish species. The results revealed that 70.07% of bluegill showed movements to swim upstream before applying the bubble, but it is considered that the ascending rate would be higher given that the fish species thinks downstream is a habitat and showed almost no movement. However, when the blocking facility was installed, most fish species showed movements to return to the downstream again by the bubble curtain, indicating a very high blocking effect. In particular, when the generating bubble was terminated, the fish species swam back to the upstream area very soon, so the fish species blocking effect using the bubble was excellent.

With the spread of untact culture resulting from the Covid-19 pandemic, the size of the car camping market has expanded to minimize contact with others. As a result, SUVs have exceeded sales of sedans, and sales of recreational vehicles (RVs) have increased by 101% compared to the same period last year. Despite the explosive increase in demand for car camping, research on car camping has not matched this increase. Therefore, in this study, we intended to conduct a study focused on car camping users. According to a survey of Naver's famous car camping cafe, it was difficult to find articles, maps, and websites with car camping places. Analysis of car camping websites showed that most only post information about the camping itself, so details of car camping places were not available. Furthermore, according to a survey derived from related prior studies and literature surveys, most users urged solutions to the problem of unauthorized garbage dumping in the car camping locations. In addition, car camping users wanted to receive information on amenities near the car camping places. Therefore, we aimed to establish a car camping website that provides basic information on car camping places and nearby convenience facilities. Moreover, to solve the problem of garbage dumping, we provided a category wherein users can post pictures of clean camping campaigns. We also developed a business model utilizing the certification process of clean camping. The business model is designed with a structure wherein car camping users are rewarded through the clean camping certification process. Compensation for clean camping certification was proposed to be provided through partnerships with domestic automakers, Korea Tourism Organization, and Small Business Market Promotion Agency.

Although research and development of existing steel-made Cowl Cross Member(CCM) was carried out with magnesium and plastic to make vehicles lighter, it is difficult to apply them to performance problems in the vehicle's mounting condition. Recently, the company is conducting research on the injection CCM of the composite insert as a lightweight component that is most suitable for mass-production of automotive parts. This is a manufacturing process that inserts composite injection bracket parts into aluminum bar, and the adhesion of the two parts is one of the important factors considering the vehicle's mounting conditions. In this study, the joint strength of Aluminum bar is one of the important factors as a study for the injection of aluminum bar into PA6-GF60 composite material. For the analysis of these research, the method of spraying adhesive to the aluminum bar and the case of knurling treatment have been analyzed and the bonding strength of the direction of rotation and lateral direction has been analyzed for each part between the aluminum bar of the cowl cross member and the shape of the injection component of composite materials.
Samkookyusa is a valuable book, which shows us ancestor's fomality, being folklorically highly evaluated. So I focus on this, look into Samkookyusa's formality especially the ceremonies of coming of age, marriage, funeral and ancestral worship. Coming of age ceremony on Samkookyusa performed by a ruler or the nobilities whoes age are uncertainly assumed as thirteen, fifteen or eighteen. In the times, our own ways of ceremonies were performed by them. Marriage ceremony on Samkookyusa, especially king Sooro and Heohwangok's amrriage procedure shows a part of royal family's ceremony before Korea dynasty and have a precious meaning as the earliest outset. Through premarital relation between Yoohwa and Haemosoo shows that there was an non-arranged match for marriage. A record of a marriage between near relatives at the early Korea dynasty is worthy. The funeral ceremony record of king Hyeockgeose on Samkookyusa could be regarded as the first one. The record pointed that using a mound as feudal lords and king Talhae's funeral ceremony showed having Seagoljang customsand making a clay figure for the ceremony. Those facts are crucial documents as helping us understand our ancient time's funeral ceremonial customs. Ancestral ceremony on Samkookyusa, specific record about ancestral ceremony for king Sooro such as fomulas, procedures, ritual fields and foods, sanctuary and portrait is a worthful record to understand a side of national ancestral ceremony of the times. Samkookyusa is a valuable book ceremonially and folklorically to understand the ancient times' ceremonies of coming of age, marriage, funeral and ancestral worship.
The purpose of this study is to present an appropriate management plan as a supplement to the scientific evidence of the currently operated distancing system for preventing COVID-19. The currently being used mathematical models are expressed as simultaneous ordinary differential equations, there is a problem in that it is difficult to use them for the management of entry and exit of small business owners. In order to supplement this point, in this paper, a method for quantitatively expressing the risk of infection by people who gather is presented in consideration of the allowable risk given to the gathering space, the basic infection reproduction index, and the risk reduction rate due to vaccination. A simple quantitative model was developed that manages the probability of infection in a probabilistic level according to a set of visitors by considering both the degree of infection risk according to the vaccination status (non-vaccinated, primary inoculation, and complete vaccination) and the epidemic status of the virus. In a given example using the model, the risk was reduced to 55% when 20% of non-vaccinated people were converted to full vaccination. It was suggested that management in terms of quarantine can obtain a greater effect than medical treatment. Based on this, a generalized model that can be applied to various situations in consideration of the type of vaccination and the degree of occurrence of confirmed cases was also presented. This model can be used to manage the total risk of people gathered at a certain space in a real time, by calculating individual risk according to the type of vaccine, the degree of inoculation, and the lapse of time after inoculation.
