This experiment was undertaken in order to investigate whether chicken can serve as a carrier for swine lungworm, Metastrongylus apri. The results abtained are summerized as follows: All chickens which were fed the infective larvae of M. apri, in the form of infected earthworm (Eisenia foctida) excreted appreximately 4.4 to 5.4 percent of the infective larvae in their feces between 2 to 10 hours after dosing. The larval excretion was marked especially during the first 2 hours. A few (0.10~0.12%) larvae were detected from the intestinal wall of chickens by pepsin-digestion method on a day after dosing, but no further migration or development of the larvae was observed. The larvae which had passed through the digestive tract of chickens retained their viability and produced characteristic lungworm disease when inoculated to guineapigs. From these results, it may he concluded that the chicken can serve as a carrier for the infective larvae of M. apri.

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

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.

X 선조사감염자충(線照射感染仔蟲)에 의한 돈폐충증(豚肺蟲症)의 면역(免疫)에 관한 실험적연구(實驗的硏究)

The purpose of present study was to investigate the possibility to immunize guineapigs and swine against Metastrongylus apri infection by the administration of irradiated infective larvae. Four main experiments were undertaken. Firstly, three groups of infective larvae irradiated at $3{\times}10^4r$, $4{\times}10^4r$, and $5{\times}10^4r$ respectively were inoculated to guineapigs and their immunogenic effects were examined from the clinical, anatomical, and serological viewpoints to decide the optimal dose of X-ray for the atenuation of them. Secondly, the migratory behavior of the larvae irradiated at the optimal dose was compared with that of normal infective larvae. Thirdly, pigs were inoculated with each 5,000 infective larvae irradiated at the optimal dose and the clinical, anatomical and serological responses of them before and after challenge were examined. Fourthly, the heated extract of adult M. apri which had been used as an antigen in the serological examinations was analyzed and compared with that of adult Ascaris suis and of adult Trichuris suis by immunoelectrophoretic method. The results obtained are summerized as follows: 1) The optimal dose of X-ray for the atenuation of the infective larvae which can minimize the pathogenecity but keep the antigenecity of the infective larvae was $5{\times}10^4r$. 2) Guineapigs could become completely resistant to subsequent challenge infection by the administration of 1,000 infective larvae irradiated at $5{\times}10^4r$, without showing any symptom of disease before and after the challenge. 3) There were some indication that guineapigs could acquire complete immunity after they overcome the infection with normal infective larvae. 4) It was shown that, in guineapigs, the $5{\times}10^4r$-irradiated larvae can migrate to the large intestine and mesenteric lymph node within a day, where they stay for as long as 16 days to stimulate the host's immunity. 5) It also was shown that, in guineapigs, the normal infective larvae challenged to resistant guineapigs can migrate to the large intestine and mesenteric lymph node, where they are affected by the immune mechanism of host within 10 days without further migration. 6) Pigs could become partially resistant to subsequant challenge by the administration of 5,000 infective larve irradiated at $5{\times}10^4r$; no clinical symptom occurred after the administration, but milder symptoms of parasitic bronchitis were observable after the challenge infection and fewer number of worms were detected from the lungs at autopsy compared with severe symptoms and much number of worms in control pigs. 7) It was shown that, in pigs, a few of the $5{\times}10^4r$-irradiated larvae can migrate to the lungs, where they stay for as long as 104 days in stunted and sterile states; their body-lengths were short and their uteri developted no eggs. 8) There was evidence that the male larvae were more susceptible to X-ray than the female larvae. 9) Antibodies relating to the administration with $5{\times}10^4r$-irradiated or normal larvae were detected from the sera of both guineapigs and pigs by means of indirect haemagglutination and agar diffusion precipitin tests. Relatively higher antibody titers were recorded by the former test, but precipitin bands were demonstrable only when the positive sera were concentrated in one tenth of original volume in the later one. 10) The antibody titers of pig sera began to rose on 14 days, kept their peak during the period from 14 th day to 21st day, and fell to a low level on 28 days after the administration of $5{\times}10^4r$ or normal infective larvae. 11) A slight increase in gamma globublin of the pig sera occurred following the administration. The gamma globulin level showed a tendency to fluctuate in acordance with the antibody level. 12) A marked eosionophilia occurred in pigs on 7 or 14 days following

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.

In a pasture located at Kyong Puk area, a group of 200 Korean native casttle showed severe coughing, dyspnea and emaciation, of which 30 cattle died from the respiratory disease. To the alived cattle, clinical, pathologicoparasitological observations and treatment with terramycin, Mintic and tetramisole (Bonasol) were carried out and the following results were obtained. 1) Paroxymal coughighings, increased respiratory rate and heart rate were observed in almost all cases. But, larval output in feces was recognized in 32 percent of the cases. 2) Morderate eosinophilia was observed in a half of the cases. 3) At autopsy, lungs were enlarged, and areas of dark consolidations were scattered in all lobes. In the bronchi, numerous adult lungworms were found. 4) The adult worms detected from the bronchi were morphologically identified as Dictyocaulus viviparus. 5) The clinical signs and larval output were disappeared after the administration of Mintic or Bonasol. 6) From these results, it was concluded that the respiratory disease of the cattle was caused by the infestation of lungworm, Dictyocaulus viviparus.

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 $25^{\circ}C$.

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.

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.
