이현범,최원필,Lee, Hyun Beom,Choi, Won Pil 대한수의학회 1976 大韓獸醫學會誌 Vol.16 No.2

The authors encountered a case of Babesiasis in Korean native cative cattle at Gyeongbug prefecture. After the clinicohematological observation the patient was treated a single dose of ganaseg and the following results were obtained. 1. Initial symptoms observed were high fever, anorexia, depression and cessation of rumination and these were followed by marked hemoglobinuria and mild degree of icterus. 2. The erythrocyte count decreased to $3.6{\times}10^6/mm^3$ and the infected erythrocyte rates were 9.7 percent with Babesia sp. and 0.2 percent with Theileria sp. 3. Marked increase in band neutrophil was observed. 4. The morphology of the protozoa in erythrocytes was different from that of so-called large-type Piroplasma: various forms including paired pear-shaped, single round, oval and pear-orspindle-shaped were detected, of which the former two forms were dominant. 5. A single dose of ganaseg administered intramuscularly was highly effective for the treatment of Babesiasis.

이현범,박청규,이희석,이차수,Lee, Hyun Beom,Park, Cheong Kyu,Lee, Hi Suk,Lee, Cha Soo 대한수의학회 1979 大韓獸醫學會誌 Vol.19 No.2

The authors encountered 78 cases of pig from two swine herds with severe dermatitis, which had been fed with commercial rations. Main clinical signs were hard crust formation or erythema and papules on the skin and retarted growth. The skin lesions were visible on the limb joints in all cases. In some cases, however, crusts occurred on the tail, perineum, hip, ear, back, or neck. In one case the entire body surface was covered with thick crust. No mites were detected on the microscopic examination of skin scrapings. Histological examination of biopsies skin specimens taken from the lesions revealed typical parakeratotic changes: the cornified layer of epidermis was irregularly inreased in thickness and contained numerous nuclei. The provision of dietary supplementation with zinc sulfate and soybean oil for 10 days showed marked curative effect.

텍스트마이닝을 활용한 주택 구입자들의 관심 주제에 대한 탐색적 연구 - 부동산 관련 세금을 중심으로 -

이현범(Lee, Hyun Beom),심충진(Shim, Chung Jin) 한국문화산업학회 2021 문화산업연구 Vol.21 No.3

모든 사람들은 인간의 기본적인 욕구 중의 하나로 주택을 소유하고자 한다. 전통적인 관점에서 보면 주택은 주거의 개념과 함께 재산 증식의 수단으로 여겨져 부동산 투기의 원인으로 지목되어 원성의 대상이 되기도 하였다. 그러나 더욱 근본적인 것은 생활을 영위할 수 있는 주거의 개념이 더욱 강하다. 요즈음의 MZ세대는 생각이 많이 바뀌었다고 하나 그럼에도 불구하고 주택 구입은 대부분의 공통적인 관심사 중의 하나이다. 특히 생애 최초로 주택을 구입하는 경우에는 부동산세에 대한 중요성이 더욱 높아진다. 주택구입에 반드시 수반되는 것이 세금 관련 문제인데, 특히 경제적으로 충분한 자금을 확보하기 어려운 경우에는 부동산세금 문제가 심각한 영향을 미치게 되며 그 중에서도 특히 취득세 문제가 초미의 관심사라 할 수 있다. 따라서 본 논문에서는 텍스트마이닝 기법을 활용하여 보통의 일반적인 사람들이 주택을 구입할 경우에 가지는 관심사와 특히 신혼부부가 생애 최초 주택 구입 시에 가지는 관심사를 기준으로 분석하였다. 연구 결과, 정부의 부동산 정책에 많은 관심을 가지고 있으며 특히 부동산세의 실질적인 혜택을 누릴 수 있도록 각종 제도를 구비할 필요가 있다. 본 연구는 탐색적 연구로서 이를 통해 부동산 관련 문제를 텍스트마이닝 등의 기법을 활용하여 보다 심층적인 연구가 지속될 것으로 기대한다. Everyone wants to own a house as one of the basic human needs. From a traditional point of view, housing was considered a means of increasing property along with the concept of housing, and was cited as the cause of real estate speculation. More fundamentally, however, the concept of living is stronger. These days, MZ generations have changed their minds a lot, but nonetheless, buying homes is one of the most common concerns. In particular, when purchasing a house for the first time in one"s life, the importance of real estate taxes becomes even higher. Tax-related issues are essential for home purchases, especially if it is difficult to secure enough funds economically, the real estate tax issue will have a serious impact, especially acquisition tax issues. Therefore, this paper used text mining techniques to analyze the interests of ordinary people in purchasing homes and, in particular, those of newlywed couples in purchasing homes for the first time in their lives. Research shows that the government has a lot of interest in real estate policies, and in particular, it is necessary to have various systems to enjoy the real benefits of real estate taxes. This study, as an exploratory study, expects that more in-depth research will continue by utilizing techniques such as text mining for real estate-related problems.

Two experiments were conducted to establish a program for the prevention of swine parakeratosis occurred recently in Korea. In the first experiment, 11 rations which were considered to be related clinico-pathologically to the incidence of parakeratosis and 5 rations not to be related were collected at farms during the period from June, 1979 to December, 1980. In addition, 23 commercial rations and 10 ingredients were also collected at feed dealers or farms. The feed samples were analyzed for calcium, zinc and unsaturated fatty acid. In the second experiment, the efficiencies of adding zinc carbonate (150mg/kg diet) with or without soybean oil (5ml/kg diet) to two control rations were tested using 20 weanling pigs. One of the control rations had low zinc (41mg/kg) and normal calcium (0.64%) and the other low zinc (57mg/kg) and high calcium (1.42%). The results obtained are as follow: 1. Content of zinc in the rations induced parakeratosis ranged from 35 to 80mg/kg with a mean of 49mg/kg; whereas those of rations not induced ranged from 97 to 182mg/kg with a mean of 182mg/kg. The difference between two means was highly significant (p<0.01). 2. The calcium content in rations related to parakeratosis was ranged from 0.56 to 1.80% with a mean of 1.30% whereas that of not related was ranged from 0.63 to 1.37% with a mean of 1.07%. The highly significant difference of calcium content between two rations were recognized (p<0.01). The calcium contents of both rations were markedly higher than that of generally recommended value of 0.40~0.80%. 3. The contents of unsaturated fatty acid in induced rations was a mean of 4.42% and it was significantly lower (p<0.01) compared with those in not induced rations with a mean of 6.70%. The content of unsaturated fatty acid of commercial rations was ranged from 5.25 to 7.81% with a mean of 6.29%. 4. Zinc content of 15 commercial ration samples among 23 were less than 97mg/kg and 21 rations contained more than 1.03% of calcium. 5. Addition of zinc carbonate to the two control rations which are low in zinc content or high in calcium content were resulted in preventive effect on the incidence of swine parakeratosis. 6. It may be concluded that the incidence of swine parakeratosis was closely related to the low zinc, excess calcium and low unsaturated fatty acid in rations, most of the commercial rations contained low in zinc and high in calcium as compared with the recommended contents. Content of Unsaturated fatty acids in the commercial rations, however, were sufficient for the prevention of parakeratosis in swine.

약유우(若乳牛)에 발생(發生)한 지방유행성(地方流行性) 백혈병(白血病)에 대하여

이현범,최원필,이근우,Lee, Hyun-Beom,Choi, Won-Pil,Lee, Keun-Woo 대한수의학회 1982 大韓獸醫學會誌 Vol.22 No.1

Authors encountered a case of bovine viral leukosis in a young cattle (10 months old) with the following findings; Main clinical symptoms observed were emaciation, digestive disorder, and marked enlargement of superficial lymph nodes. Biopsied specimen of the lymph nodes revealed characteristic histological picture of bovine leukosis. A severe degree of leukocytosis (108,000/cmm) accompanied by marked lympocytosis (96%=103,680/cmm) was detected from the hematological examination of peripheral blood. Most of the lympocytes(94%=101,520) were large-sized, immature, and abnormal in their morphology. In addition, a pronounced anemia (1.78 million/cmm) without regenerative evidence of erythrocyte was noted. The serum of the patient showed positive reaction against gp antigen of bovine leukosis virus in agar-gel diffusion test.

Authors encountered a case of elk babesiosis in Daegu, Korea. The main symptoms observed before the death of the patient were elevated rectal temperature, severe degree of hemoglobinuria, icterus and recumbency. Hematologically, the erythrocyte count was 1.93 million per cu.mm 11% of which were infected with Babesia. Most(88%) of the protozoa were spherical or vacuolated ring form in shape, resembling B. bovis. However, the sizes (0.98-2.85) were slightly smaller than the latter. About 7% of the protozoa were vacuolated oval, the size of which varied from $2.06{\sim}2.95{\times}1.08{\sim}1.97$ ($2.53{\times}1.51$ in average). The remaining 5% were irregular in shape. Pear-shaped were scarcely observed. A three-gears-old Korean native cattle was inoculated subcutaneously with the elk's blood. However, no evidence of susceptibility was observed until 30 days postinoculation.

Authors observed an outbreak of porcine pleuropneumonia at a piggery in Gyeongbug, Korea, which were diagnosed on the ground of clinical and pathological findings with the following results. 1. One hundred and forty weanlings out of 200 ones died suddenly without noticiable signs during the period of 15 days. All of the dead pigs showed formy, blood-tinged discharge from the nose and mouth. 2. Main clinical findings observed from 60 alive pigs from group consisted of fever, cyanosis severe degree of dyspnea and pleuritic friction rub. 3. On hematological observation for typical 5 cases leukocytes showed marked degenerative left shift with leukopenia (10500-13070/cmm), neutropenia (7-13%) and increase in the number of band neutrophils (6-27%). 4. The most prominent and constant pathological changes observed at necropsy for dead or alive pigs consisted of fibrinous pleurisy with partial adhesion, overlying of the pulmonary surface with fibrinous menbrane and necrotic pneumonic lesions with marked edema and congestion of lung parenchyma. 5. From these results the outbreak was considered to be typical porcine pleuropneumonia, although no bacteriological isolation was attempted.

Present study was undertaken in order to evaluate the lead contents of various feedstuffs produced in Korea and the effect of the burning of gasoline by automobiles on the lead contents. Ninety-one samples near and 95 far road were collected from 9 regions(Do). All of the samples were washed, dry-ashed and analyzed for lead content using atomic absorption spectrophotometer. The mean values obtained were checked for significance of difference using computer. The results obtained were summerized as follows: 1. The lead content in ${\mu}g/g$ of agriculture-byproducts were measured with the following mean values and ranges(in parentheses). Rice bran: $2.07{\pm}1.67$ (0-5.00), rice hull $1.84{\pm}1.18$ (0-3.71), rice straw, $1.27{\pm}1.09$ (0-3.62), soybean pod:$4.55{\pm}3.13$ ($1.13{\pm}10.43$), and wheat bran: $1.69{\pm}0.86$ (0-3.65). 2. The lead content in ${\mu}g/g$ of pasture plants were measured with the following mean values and ranges. Kudzu:$2.71{\pm}1.74$ ($0.38{\pm}8.75$), leed: $2.03{\pm}1.61$ (0-4.54), lespedeza:$4.73{\pm}5.93$ (0-31.25), sagebrush: $4.08{\pm}3.75$ (0-12.18), Korean-grass: $2.11{\pm}1.38$ (0-5.50), maizestalk: $2.62{\pm}2.35$ (0-8.65), clover: $3.83{\pm}2.97$ (0-12.19), alfalfa: $7.14{\pm}0.97$ (4.46-9.25), and timothy: $5.86{\pm}4.79$ (0-9.25). 3. Fourteen samples (22.2%) out of 63 agriculture-byproduct samples and 42 (34.2%) out of 123 pasture plant samples showed lead content of more than $3{\mu}g/g$ which are said to be the upper limit value for cattle. 4. No significant difference between the mean lead contents of near road, and those of far road was recorgnized. 5. The regional mean values for all kinds of samples collected in Kyungbuk and Kyungnam were significantly (p<0.05, p<0.10) higher compared to those in Chungnam and Jejudo.6. From these results it may be concluded that the burning of gasoline by automobiler did not affect on the lead contentes of washed feedstuffs produced in Korea at present.

기업의 사회적 책임과 재무적 성과의 영향 연구: 상이한 문화적 배경의 기술 산업기업 비교 중심으로

이현범(Lee Hyun Beom) 한국문화산업학회 2024 문화산업연구 Vol.24 No.2

The study aimed to understand how Corporate Social Responsibility (CSR) impacts Financial Performance (FP). It specifically investigated factors influencing the CSR-FP relationship in technology industry companies from different cultural backgrounds, such as Western and Asian nations, to provide strategic insights. References were made to previous research on technology industry companies representing each culture to achieve this goal. The study organized its theoretical framework, major variables, and research model based on insights from prior research. Findings were compared and reinterpreted in line with the studys objectives using empirically investigated results. In research focusing on American companies as representatives of Western culture, the study explored the relationship between historical and social aspirations and CSR participation from the perspective of corporate behavior theory. In contrast, research on Korean companies, representing Asian culture, examined the relationship between CSR and FP, with corporate reputation (CR) as amoderating variable. Results indicated variability in the variables applied and outcomes across the study subjects. ForWestern culture represented by American companies, higher financial performance relative to historical goals decreased CSR participation, whereas surpassing social goals increased it. In contrast, in the context of Asian culture, particularly among Korean companies where CSR adoption is relatively recent, corporate reputation was found to significantlymoderate the relationship between CSR and FP. These findings underscore the importance of activelymanaging corporate reputation and investing in CSR practices for enhancing financial performance.

In this study two sets of experiments were undertaken. Firstly, the embryonated eggs and first-stage larvae, sprayed in disinfected soil, were exposed to different temperatures. Then, the viabilities of them were weekly determined by inoculating the soil to earthworms, Eisenia foetida. Secondly, the infective larvae, seperated from the earthworms and suspended in tap water, were also exposed to different temperatures and their viabilities were checked microscopically at weekly intervals. The results were summerized as follows: 1. The maximum longevities of embryonated eggs and first-stage larvae were determined as 1 week at $35^{\circ}C$, over 36 weeks at $25^{\circ}C$, $15^{\circ}C$, and $5^{\circ}C$, 32 weeks at $-5^{\circ}C$, and under 1 week at $-15^{\circ}C$. 2. The mean numbers of infective larvae detected from the test earthworms were greatest at $5^{\circ}C$, and decreased with rise or fall of the temperature. 3. Infective larvae freed from the intermediate host were able to survive for 2 weeks at $25^{\circ}C$ and 3 weeks at $15^{\circ}C$. However, they lost their viabilities in a week at $35^{\circ}C$, $5^{\circ}C$, $-5^{\circ}C$, and $-15^{\circ}C$. 4. The number of living infective larvae at $15^{\circ}C$ was greater than at $25^{\circ}C$.
