장현유,이영석 한국버섯학회 2004 한국버섯학회지 Vol.2 No.2

This experiments were conducted to study on the economic analysis of Phellinus spp.(Comercial name: Sanghwang mushroom). These results were as follows: Phellinus spp. can be cultivated about 4 years by one time inoculation. This mushroom has been cultivated by the method of burying log into the soil(BM) at the first time. Recently, however, the method of hanging log on the shelves in the house(HM) is used, because HM has more advantage than BM that HM can be cultivated more pieces of logs than BM. On the other hand, HM is required to invest more 5,678,230Won for the equipments than the BM. And also, HM is required 14,400 pieces(2.8 times) more log numbers than BM 5,000 pieces. Also, HM is required more 3,680,000Won to purchase log, 1,104,000Won to purchase spawn. The cost of production is required to 20,180,971Won for BM, and 37,953,825Won for HM. Accordingly, product cost of HM is 1.9 times higher than BM. The operating cost is required to 1,207,712Won for BM, and 24,075,432Won for HM. Accordingly, operating cost of HM is 2.0 times higher than BM. The net income is 580,940,000Won for BM, and 1,683,300,000Won for HM. Accordingly, net income of HM is 2.9 times higher than BM. The income is 589,040,000Won for BM, and 169,718,000Won for HM. Accordingly, income of HM is 2.9 times higher than BM. In conclusion, HM is required 2.8 times more logs. HM has 1.03 times more products per a piece of log. HM has 1.9 times more production cost, and 2.0 times more operating cost. As you read above, HM and BM have two different aspects. BM is required less investment cost than HM, but BM has lower income because of the different capacity of production. By the comparing those two methods, HM is resulted more efficient method for the producing mushroom. Only in the side of cash flowing, the cash expenditure of BM is required less money at first year. But it has no production at first year. BM would get the income after 2 years buring the logs. The cash expenditure of HM is required much money for the equipments and the logs at first year, but HM would get the income at first year. 상황버섯은 한번 접종하여 4년간 재배되는 버섯으로서, 원목의 일부를 땅에 묻어서 재배하는 지면재배 방식으로 상업적 재배가 시작되었으나, 최근에는 보다 집약적인 재배방식으로 원목을 덕(균상)에 매달아서 재배하는 지상재배가 시도되고 있다. 지상재배는 덕(균상)을 만들어 많은 숫자의 골목을 매달아 재배하는 것을 제외하면 그 재배과정이나 작업요령에는 큰 차이가 없다. 다만 지상재배는 덕(균상)이라는 시설투자에 5,678,230원이 더 들고, 원목이 지면재배 5,200본의 2.8배인 14,400본이 소요되어 368만원의 원목비와 그에 따른 종균비 1,104,000원 등이 더 드는 것으로 밝혀졌다. 재배사 100평을 기준으로 한 4년간의 생산비는, 지면재배가 20,180,971원 지상재배가 37,953,825원으로, 지상재배가 지면재배의 1.9배에 이르고, 경영비는 지면재배가 12,077,712원, 지상재배가 24,075,432원으로, 지상재배가 지면재배의 2.0배가 되었다. 순수익은 4년간 100평에서 지면재배가 5억 8,094만원, 지상재배가 16억 8,330만원으로, 지상재배가 2.9배 많았고, 소득은 지면재배가 5억 8,904만원, 지상재배가 16억 9,718만원을 얻을 수 있는 것으로 나타나, 소득도 지상재배가 지면재배의 2.9배가 되었다. 이는 재배 원목수의 차이 2.8배에 골목 1본당 수확량의 차이 1.03(541g : 523g)가 더해진 것과 비슷한 수준으로, 생산비 차이 1.9배나 경영비 차이 2.0배보다 훨씬 크다. 이상을 종합하면, 지면재배는 지상재배에 비하여 투자비는 적게 들지만, 소득도 그만큼 낮고, 재배 원목과 버섯 수확량이 지상재배에 비하여 적기 때문에 저투입-저수익 재배방식이라고 말할 수 있고, 지상재배는 투자비와 노동력 투입이 많지만, 수익은 그보다 더 높다는 것을 확인할 수 있다. 다만 현금흐름 측면에서는, 지면재배의 경우는 첫해의 자금지출은 지상재배보다 적지만, 첫해에 수확이 전혀 없기때문에 투자 후 2년 정도가 지나야 투자비를 회수할 수 있지만, 지상재배는 비록 첫해의 자금수요는 그보다 크지만, 첫해부터 수확이 가능하기 때문에, 전부는 아니더라도 첫해부터 투자비 회수가 가능하다는 점에도 유의해야 한다고 하겠다.

유영준,조현호 경주대학교 창의력개발연구소 2004 創意力開發硏究 Vol.- No.7

The purpose of this research is to provide guiding alternatives of sound leasure activities by breaking with terms for types and behaves of its in university student's daily life. For these me, students who took class on 「Theory of leisure, has been studied concepts of leasure spontaneously as a observer, and then they has been submitted to diary-style life record table which are done activities of one week. By doing practice on diary analysis method on basis of one's life record, which are analyzed student s life and act for one week by emphasis upon leasure time. And also to increase reliance on research results, by presenting in class examples of 10 persons among main interview group, whether are unified with their opinions. The results has been shown that portion of leasure activities has various value at range of 15.7~38.0 percentage on total activities time. Most examples have presented that students have been spent leasure time efficiently, after they have examined with leasure time and made life record by themselves.

Patient with complaints of swelling, pain in the maxillary region and discomfort visited Seoul National University Dental Hospital in August last year. Clinical examination and diagnostic imagings implied he was suffered from fungal hyphal infection but no causative fungus was found by the histopathologic and microbiologic investigation. Therefore he was diagnosed with nonspecific inflammation. But as yet, we do think this case is very similiar to some kinds of mucormycosis. So we presented this case for more thorough discussion. Followings are founded in the examination. 1. Patient had suffered from Diabetes mellitus and complained of stuffness, headache, swelling in buccal checks and paresthesia. And we found more maxillary bony destruction and ulcer with elevated margin in the palate by clinical examination. 2. In the first visit, Plain films revealed general bony destruction of the maxilla, radiopaqueness in the sinonasal cavities. CT and MRI showed soft tissue mass filled in the paranasal sinus except frontal sinus and bony destruction in involved bones. 3. No causative bacteria and fungus was found in the biopsy and microbiologic cultures. 4. Caldwell-Luc operation and curettage were carried and antibiotics were taken for 4 months. But now he was worse than in the past. 5. In the second visit, involvement of orbit, parapharyngeal sinus, clivus, cavernous sinus and middle cranial fossa were seen clearly in the CT and MRI.

Background and aims: The Apolipoprotein E is a ligand of both the protein component LDL receptor as well as the apo E LDL-Receptor related protein (LRP). It modulates the receptor binding of lipoproteins, with the apolipoprotein E found on cell surfaces as its component, thus serving an important role in the lipid metabolism by carrying out the intracellular transport of cholesterol in lipoproteins. The gene for apolipoprotein E is the product of three common genotypes as well as many more rare alleles. The common genotypes are ε2, ε3, and ε4, and are expressed in the three phenotype isoforms of E2, E3, and E4. In the event that E4 is the main component, a rise in the cholesterol level, as the result of down-regulation of the LDL receptor, is observed. Therefore, those samples with E4 genotypes are known to be in much higher risk of coronary artery disease than those with ε3/ε3, while those with ε2 are in low risk (with the exception of hypertiglyceremai Ⅲ). The aim of this study is to analyze in patients with ischemic heart disease the role of aplipoprotein E alleles in order to seek its correlation with coronary artery disease, as well as to seek whether the polymorphism of apo E produces any differences in the severity of coronary artery disease according to plasma lipid levels. Methods: The subjects for study were 273 patients admitted to the Internal Cardiology Division of the Soonchunhyang University Hospital form December 1998 to February 1999. The subjects were divided into the two groups of which one was ischemic heart disease (IHD) experiment group totaling 105 (avg.60.1 years of age, male/female ratio = 69/36) and the control group totaling 168 (avg. 59.7 years of age, male/female = 73:95). The coronary angiogram was given to 127 subjects, and of this total, 94 have developed significant stenosis in the coronary artery. The stages of the analyzing of the apo E phenotype was first, the separation of DNA from the blood samples, subjecting it to the PCR from with 228 base pairs of expanded products were obtained. The band was determined by means of the reverse hybridization principle on the nitrocellulose strip. Results: From the 105 patients the distributions of apo E phenotypes were as follows: ε3/2(5.7%), ε4/2(1.9%), ε3/3(70%), ε4/3(20%), ε4/4(1.9%). The relative frequencies of each allele are as follow: ε2 (0.038), ε3 (0.833), ε4 (0.128). The results show as follows: ⅰ) The IHD experiment group to have a higher occurrence of ε4/3 phenotypes as well as ε4 alleles than the control group. ⅱ) Both the control group and IHD group showed the largest distribution of ε3/3 for phenotypes, and ε4 for alleles. ⅲ) The IHD group showed less ε2/3 phenotypes as well as significantly less allele frequency of ε3 in comparison to the control group. ⅳ) the IHD group showed a much lower level of HDL in comparison to the control group, while the LDL was significantly higher; samples including the apo ε2 showed a significantly higher level of HDL than those without. Among the control group, samples including apo ε2 showed a significantly higher level of TG (triglyceride) than samples without. No significant difference was found between the experiment apo ε4 sample and the control plasma lipid sample. ⅴ) No significant correlation was found between an apo E polynorphism and the number of involved arteries of a coronary angiogram. Conclusion: Between the experiment IHD group and control group were found differences in the frequency of alleles. The polymorphism of apo E alleles may contribute as a risk factor to the development of heart disease by involving itself in the metabolism and modulation of plasma lipids.

The transmission factor of wedge filter is usually measured on field center at a fixed depth, preferably that of maximum buildup or d_(max). But dose profiles produced at field center may be difference from that of off axis. The implementation of wedge with independent collimator is desired in a number of clinical situations. We have attempted to measure dependence of the wedge transmission upon off axis in case of using wedge with independent collimator. And those redefined relative to a transmission at field center. The discrepancies in wedge factor between off axis and center shapes up from 2.4% to 17.2%.

저자들은 항정신병약물 chlorpromazine 치료 중에 음경지속발기증이 발생하여 수술까지 시행하여 회복된 환자 1례를 체험하였기에 문헌고찰과 함께 보고하였다. 항우울제 trazodone과 함께 chlorpromazine, thioridazine과 같은 항정신병약물이 음경지속발기증의 원인과 관련이 있는 것으로 알려지고 있다. 이러한 약물에 의해 유발되는 음경지속발기증의 기전에 대해서는 알파-아드레날린 차단으로 인한다는 설이 많은 지지를 받고 있다. 치료는 보존적인 치료와 외과적인 치료가 있으며, 외과적인 치료로는 음경해면체 천자와 흡입 세척술 그리고 분로를 만들어 주는 방법들이 있다. 음경지속발기증은 신속한 진단과 치료를 하지 않을 경우 영구적인 발기불능을 초래할 수도 있는 부작용이므로 향정신약물 투여시 이에 대한 관심과 주의를 가져야 할 것이다. Antipsychotic drugs can induce several sexual side effects. Priapism, one of the side effects, is defined as "the persistent abnormal erection of the penis, which usually occurs without sexual desire". There has been an increasing number of reports recently linking the etiology of priapism with psychotropic medication. The drugs known to be associated with priapism are psychotropic drugs such as trazodone, chlorpromazine, thioridazine as well as antihypertensives, anticoagulants and so on. The mechanism of a drug which induces priapism is proposed to be mediated by its alpha-adrenergic blocking effect. Prompt diagnosis and treatment are essential. Priapism is a severe side effect, which can lead to impotence if prompt diagnosis and treatment are not carried out. There are medical and surgical treatments for priapism. The surgical treatments usually involve aspiration, irrigation and the creation of shunt. We report a case of priapism which developed after two years of chlorpromazine treatment. He is a 20-year-old man with schizophrenia. He experienced two times of brief episode of prolonged penile erection before developing intractable priapism. He was treated by shunt operation which showed satisfactory relief of priapism. It seemed by this case that duration and dosage of chlorpromazine were not closely related with priapism. Psychiatrist is needed to give attention to the priapism as one of sexual side effects due to antipsychotics though it is not common.

대학생의 여가 인식에 관한 연구 : 경주대학교 재학생을 대상으로 focused on KYONGJU University student

조현호,유영준 경주대학교 2000 論文集 Vol.13 No.-

Korean is exposed to a rapid growth in economy and considerable amount of time for leisure. There is no doubt that the leisure industry is playing a significant role in making our lives enjoyable and therefore leading a quality lift. In a range of research. it has been shown that the essence of leisure functions properly where the degree of leisure satisfaction is high. Thus, this study attempts to identify the cognition of leisure by undergraduate students in Kyongju University and to suggest alternative solutions for then. The research findings and their implications are summarized as follows. Firstly, a large percentage of the students take a serious view of work and leisure. Secondly, the satisfiers of own leisure activity are rather than dissatisfied students, because they regard their leisure activities as reasonableness and soundness. Lastly, students consider leisure as their mental state of comformt and pleasure. The results implies that systematic and in-depth education on the leisure and enrichment of leisure facilities are required in order to become higher students' satisfaction of own leisure activities.

This research provides a comprehensive analysis of consumer information search behavior in e-shopping. It investigates the determinants of amount for consumer information search in e-shopping in order to provide useful information on consumer decision making and consumer related marketing and public polices. Based on the review of literatures, amount of consumer information search is investigated by three different ways: (1) the number of visiting e-shopping, (2) the length of decision making time, and (3) the length of visiting time. And amount of consumer information search is assumed to be explained by several demographic variables(i.e. sex, age, income, education, marital status) and environmental variables(i.e. experience of purchase, perceived risk, types of internet mall, types of product and experience of internet). The empirical result of this study showed that amount of information search in e-shopping is explained by age, marital status, perceived risk, experience of purchase and experience of internet. The empirical results provide useful implications about consumer behavior and consumer related policies. One of the most important of these implications is the importance of providing objective and efficient information system in e-shopping. These results might also be used in teaching and in further research about consumer information behavior in e-shopping, the formulation of marketing strategies and public policies.

This paper is about analyzed individual virtual cell loss probability and virtual bandwidth method using virtual link capacity for CAC. Since ATM networks have to accept various traffics, it is important to obtain the statistical multiplexing gain, But deterioraton of Quality of Service(QoS) can occur due to it. So the guaranty of QoS and the efficient utilization of resource are the key subjects in the reasearch. It is necessary to satisfy both conditions, but there are trade offs in these two. This paper shows the boundary of these trade offs, and these results are adopted to traffic control, and are applied to CAC.
