This paper aims at providing a concrete plan to improve technical and vocational teacher education in the College of Industrial Education of Chungnam National University. It is intended to propose a practical four-year regular and short-term course. Also, the estimated required facilities is included in this study as well as their management. The main conclusions and recommendations are summarized as follows; 1) The numbers of students enrollment should be reduced to 220 students which is the approximate number of future demand. 2) In order to offer to the students a broader education and to cope with the increase/decrease in demand of technical and vocational teacher within a specific field, the 8 department existing at the present (Department of Architecture Engineering Education, Civil Eng. Educ., Metallurgical Eng. Educ., Mechanical Eng. .Educ., Electrical Eng. Educ., Electronic Eng. Educ., Industrial Chemistry Educ. and Industrial Technology Educ.) would be combined into 5 (Department of Construction Engineering Education, Mechanical Eng. Educ., Electrical Eng. Educ., Industrial Chemistry Educ. and Industrial Technology Educ.). 3) The short-term course program is recommened to provide additional training and education to those candidates who already have experience in technical fields to meet an occasional demand. 4) It is necessary to add the Teaching Profession Section in the administrative organization of the College.

Functional electrical stimulation(FES) is known to increase muscle bulk and strength and prevent muscle atrophy in complete paraplegic patients. And other benefits include peripheral adaptations which improve muscle endurance, girth, and appearance, as well as central circulatory adaptation which enhances aerobic(cardiopulmonary) capacity. Good candidates for FES include spinal cord injured patients who have clinically complete upper motor neuron lesion between T4-T12. But we experienced incomplete L1 paraplegic patient who has improved maximal knee extension power, endurance, circumference and cross-sectional area of the thigh and the shank after FES-induced exercise for 44 weeks. So we recommend more trial of the FES-induced exercise to not only complete but also incomplete lumbar paraplegic patients.

Traditionally, the scarce and expensive resources in communication networks has been the bandwidth of transmission facilities; accordingly, the techniques used for networking and switching have been chosen so as to optimize the efficient use of that resource. One of them is the packet switching for data communications, which is much different from the circuit switching. It allows multiple users to share the data network facilities and bandwidth, rather than providing specific amounts of dedicated bandwidth to each users. One main challenge therefore has been to design and build cost-effective packet switching networks. In this paper, we develop a mathematical programming medel and heuristic algorithm for designing the packet switching networks with hop-count constraints. To develop an efficient heuristic, we apply the Lagrangian relaxation method. Some valid inequalities, which have been known as the tight constraints, are considered to improve the bound for Lagrangian sub-problem. The computaional experiments show that the performance of the proposed heuristic is very satisfactory in both the speed and the quality of design solutions generated.

Reaction of benzaldehyde derivatives with ethylacetate afforded ethylbenzylidenecyanoacetate. Especially, the crystal structure of ethyl p-methoxybenzylidenecyanoacetate were demonstrated by X-ray diffrection method. The crystal structure is only exist in E-form. The kinetic studies on the mechanism of nucleophilic addition of thiophenol to ethyl benzylidenecyanoacetate have been investigated by UV-spectrophotomery and the rate equation which can be applied over wide pH range was obtained. From the rate equation, effect of generalbase and substituent, the fellowing reaction proposed. Below pH 3.0, thiophenol added to the double bond, while above pH9.0 thiophenoxide ion added to the double bond. In the range of pH from 3.0 to 9.0, these reaction occurred competitively.

This study aims to investigate the actual extracurricular education and economic strains of households. For these purposes, 372 households in Kwangju with students but collegians were surveyed through the questionnaire method. The frequency, percentile, One-way ANOVA in GLM and Chi-square test were used for the data analysis. The Results were as follows: 1. Most of households takes extracurricular lessons(334) and be willing to do (268). Many have concerns about it and need it. 2. The average lesson number is 2 subject and average cost per household is 177,000 won. 3. The average economic strains due to the extracurricular cost is 22 points. Economic strains differ according to the socio-economic variables (e. g. father's educational level, mother's educational level, average income level per month, and to the attitude variables, extracurricular will in future, parent concerns, and needs. Here we can conclude, many households have economic strains due to extracurricular fees. And the economic strains by extracurricular lessons are so undesirable to family growth and development that government have to reform the educational structure. So the social need to the extracurricular lesson will be taken away. But in reality, still extracurricular lessons are so needed that the households must have any strategies to face the economic strains.

甘豆湯煎湯液이 순환기 Anaphylaxis에 미치는 影響

李柱憲,文炳淳,李基商 대한동의병리학회 1998 동의생리병리학회지 Vol.12 No.1

Anaphylaxis는 無防禦란 뜻으로 抗原刺戟에 의하여 감작된 生體가 일정기간 후에 동일한 抗原과 接觸했을 때 수분에서 수십분 내에 급격히 증상을 나타내는 현상이다. 甘豆湯은 甘草·黑豆 二味로 구성되어 있으며 甘草는 和中하여 해독작용이 있고, 약리학적으로 혈압상승작용, 抗allergy 작용, histamine과 같은 allergy를 일으키는 物質의 血管 透過性 억제, 心血虛에 의한 不整脈, 動悸에 效果가 있다고 알려져 있다. 黑豆는 散熱하여 해독하는 작용이 있고, 예로부터 黑豆만 사용했을 때 보다 甘草를 加하여 사용했을 때 탁월한 해독효과가 있다고 하였다. 따라서 本 方은 각종 allergy 반응을 일으키는 特定物質에 대한 해독작용과 抗allergy 작용이 있으므로 순환기 anaphylaxis에 效果가 있을 것으로 생각되어, pithed rat에서의 순환기 anaphylaxis 반응에 미치는 效果, guinea pig 심장에서의 anaphylaxis 반응에 미치는 效果, guinea pig의 기관지평활근에 미치는 效果, rat의 PCA 반응에 미치는 效果에 대한 실험을 觀察하여 有意性 있는 다음과 같은 結果를 얻었다. 甘豆湯煎湯液은 in vivo model인 pithed rat에서 순환기 anaphylaxis을 저해하는 작용이 있으며 anaphylaxis에 의한 動物의 치사율을 현저하게 억제하였고, pithed rat에서 지속적인 혈압하강을 有意性있게 억제하였으나 頻脈현상을 차단하지는 못하였다. 甘豆湯煎湯液은 guinea pig 심장에서 anaphylaxis에 의한 심장기능의 부전을 차단하지 못하였고, guinea pig의 기관지평활근에서 LTD₄, histamine, 5-HT 등으로 유발한 수축현상을 억제하지 않았으나, rat에서의 PCA 반응을 有意性있게 억제하였다. 以上의 結果로 보아 甘豆湯煎湯液은 순환기 anaphylaxis를 포함한 type Ⅰ allergy현상을 차단하는 效能이 있으며 이는 직접적으로 anaphylaxis에 관여하는 매개물질을 길항하기 보다는 이들 매개물의 생합성을 차단하거나 肥滿細胞로부터의 遊離를 차단할 가능성이 있다. 따라서 이러한 순환기 anaphylaxis 차단작용은 심장보다 말초혈관에서의 혈관이완이 주 작용으로 보여진다 This study was investigated the inhibitory activity of Gamdutang water extract on type Ⅰ immediate hypersensitivity of anaphylatic type. The results of this study were as follows: 1. Gamdutang water extract ameliorated the cardiovascular anaphylactic response and thus reduced lethality in the vivo rat model (pithed rat). 2. The ameliorating effect was related to the blunting of sustained depressor effect appeared follwing antigen challenge, but the tachycardic response was not influenced. 3. In the isolated guinea pig heart, Gamdutang water extract did not prevent the occurrence of cardiac failure induced by anaphylaxis. 4. Gamdutang water extract did not relax the contractility response of isolated guinea pig trachea to LTD4, histamine or 5-HT. This result indicates that te Gamdutang water extract does not possess direct inhibitory action on these major anaphylactic mediators. 5. Gamdutang water extract could be effective against other types of anaphylaxis since the substance was effective in PCA test. The results suggest that Gamdutang water extract is effective in preventing Type Ⅰ allergy such as anaphylaxis. Gamdutang water extract may not antagonized directly major anaphylactic mediators such as LDT4, histamine or 5-HT. Rather it seems that Gamdutang water extract interferes the release of these mediators from mast cells in the advent of anaphylaxis, or it may inhibit the biosynthesis of these substances. Gamdutang water extract's main site of action seems to be peripheral resistance vessels, not the heart.

쌀 생산비를 줄이고 대경지 규모화 영농에 적응할 수 있는 농기계 개발을 목적으로 연구개발한 대규모 경지적응 트랙터 부착 대형벼이앙기의 구성과 특징 및 개발시작기의 재배적 실용성 평가결과를 요약정리하면 다음과 같다. 1. 트랙터 부착 12조 대형벼이앙기는 크게 바퀴자국 제거로타리, 문짝형 정지판, 이앙장치부 등으로 구성되어 있다. 2. 트랙터 부착 12조 이앙기는 트랙터 동력을 이용하여 로타리, 정지 및 이앙작업이 동시에 이루어 질 수 있도록 개발하였다. 3. 바퀴자국을 없애는 날은 기존의 로타리 날을 교체하면 되도록 반달형 날로 제작하였다. 4. 이앙기는 이동시는 접을 수 있도록 설계 제작되어 대형화가 가능하므로 기존 6조 승용이앙기에 비하여 이앙작업 능력이 1.5배 이상이었다. 5. 트랙터 부착 대형벼이앙기는 트랙터와 같은 큰 동력원을 이용할 수 있으므로 측조시비기, 긴매트모 탑재 등 다양한 작업기 및 기능을 추가로 부착 가능하도록 설계되었다. 6. 트랙터 부착 대형벼이앙기는 어린모 및 중묘이앙시 결주율은 3.0∼4.3%로 기계이앙기 결주 허용범위 5% 미만이었다. 하지만 무경운 논에서는 이앙작업은 가능하나 부묘율이 다소 높은 점은 보완이 필요하다. To develop a labor saving rice cultivation technology, a new tractor attached rice transplanter has been developed for large scale farming and its field performance was evaluated. The rice transplanter consists of three major parts such as rotary for removing tractor tire furrow, door-shaped soil leveling plate and transplanting equipment. The rice transplanter is operated using the power of the tractor and performs rotary, harrow and seedling transplanting simultaneously. A half moon shaped rotary blade was found to be very efficient to remove tire furrow developed during seedling transplanting and the original rotary blade can be replaced easily with existed rotary blade. The seedling transplanting part of the transplanter was designed to fold into small size and the transplanting efficiency of the transplanter was found to be 1.5 times higher than that of the conventional riding type six row transplanter. Since the transplanter is operated through a strong power of the tractor, the additional attachment such as fertilizer application apparatus and long mat rice seedling carrier is possible. Based on the field performance of the transplanter, although the missing hill percentage showed roughly with 3.0∼4.3% for 10-day and 30-day old seedlings but the percentage is less than 5% which is maximum missing hill permit in the transplanting rice. Seedling transplanting in no-tillage field condition is acceptable but floating seedling percentage is still high and thus further technology improvement for minimizing floating seedling percontage is needed.
