Two 7 months old Korean native beef calves, which were suspected as ergotisms were referred to the Veterinary Teaching Hospitals Chonnam National University in February 1997. Those showed severe lameness as a result of a dry gangrene of the lower part of both hindlimbs which unilaterally were detached, tail necrosis and retarded growth. On the skin of the extremities of both hindlimbs were clearly appeared indented line, hypertropic granuloma and hemorrhage, from which were isolated gicrosp$\theta$rum gysiNㅁt. On the X-ray views of hindlimbs and the longitudinal sectioned metatarsal bones were not observed any changes of osteomyelitis except slightly increased osteophytes and soft tissue swelling. Clnical and anatomical observations were suggested that these calves were affected by the ergotism.

During cosmetic treatments, SURFACTANTS penetrate into KERATINOUS TISSUES (hair, skin and nails). Whereas some of these surfactant molecules migrate to the vital tissues, a considerable fraction remains bound to the keratin. The extent of binding depends both on the nature of the head group and the length of the hydrophobic tail of the detergent molecules. In addition to entering the amorphous region of the keratin, some of the detergents also penetrate into the crystalline microfibrils and change their structures affecting their tensile properties. Owing to an uneven distribution of detergent molecules in the tissues, an anisotropy of the elastic moduli will occur, resulting in considerable internal stresses which, in rum, might lead to a deterioration of hair, skin and nails. The chemical behavior of keratins is also influenced by the presence of absorbed detergent in their structures. Depending on the detergents and the conditions, these effects can be either protective or detrimental. The deposition of detergent molecules into keratin can be enhanced or diminished by the inclusion of appropriate ingredients into the product formulae.

본 논문에서는 유아부터 노인까지 간단한 조작법으로 쉽게 즐길 수 있는 게임을 만들고자 한다. Space Bar를 주로 이용하는 One-Button방식의 게임으로 연타를 하는 미니게임들이지만 '순발력'과 '정확도'를 필요로 하는 게임이다. 다른 게임들은 화려한 이펙트와 다양한 조작법으로 흥미를 이끌어 내기는 하지만 저연령층과 고연령층이 다가서기엔 힘든 부분이 있다. 그래서 간단한 조작으로 게임을 즐길 수 있는 게임을 만들어 보고자 했다. 친근감 있는 시나리오와 캐릭터를 통해 남녀노소 누구나 쉽게 접할 수 있고, 오락적인 요소만 있는 것이 아니라 게임을 통한 성취감과 경쟁심을 유도함으로서 게임에 더욱 몰입 할 수 있다.

The study was carried out to investigate the proximate composition, amino acids, dietary fiber, ascorbic acid and minerals contents of seven edible wild vegetables; an Evening Primerose($S_1$), a Spiderwort($S_2$), the Flower of a Convolvulus($S_3$), So Ru Jaeng Yi($S_4$), Shoe Bi Rum($S_5$), O Yi Pul($S_6$), Jip Sean Na Mul($S_7$). Results as summarized as follows: 1. The moisture contents of samples were determined as 64.43~88.30% The largest amount of them was contained in a Spiderwort($S_2$) and the smallest was in a Jip Sean Na Mul($S_7$), 2. The crude protein contents of samples were determined as 2.71~8.10%. The largest amount of them was contained in a O Yi Pul($S_8$), the smallest was in the Spiderwort($S_z$). 3. A relatively large amount of total amino acids were determined in samples. The abundant amino acids existed in the samples were Glutamic acid(10%), Lysine(8%), Leucine(8%) and the content of Methionine was very low. The highest level of them was found in the Convolvulus($S_3$), 4,419.6 mg% and the lowest was Shoe Bi Rum($S_5$), 2,393.1 mg% 4. The Ascorbic acid contents of samples was determined as 55.99~31.8O mg. The highest level of them was found in the Jip Sean Na Mul($S_7$) and the smallest was in the Primerose($S_1$) 5. The mineral contents of samples were determined. A relatively large amount of K, Ca and Mg were found in the samples. Especially the level of Iron was higher than that of any other vegetables. 6. The contents of dietary fiber were determined as 31.8~79.9%. The highest level of them was found in the Convolvulus($S_3$) and the lowest was in the Spiderwort($S_2$). The highest level of them was found in the Convolvulus($S_3$) and the lowest was in the Spiderwort($S_2$). From the above mention, we can say that the contents of protein, fat, fiber, total amino acids and iron were abundant in wild grasses than that of any other wild and cultured vegetables. The contents of ascorbic acid, potassium, calcium and magnesium were similar and the moisture is significantly low compared with any other vegetables.

PFAPA 증후군은 소아 시기의 주기성 발열의 원인의 하나로, 급작스럽게 시작되는 발열과 더불어 아프타 구강 궤양, 인두염과 경부 림프절염이 동반되는 것을 특징으로 하는 질환이다. PFAPA 증후군의 원인은 아직 알려져 있지 않으며, 가족력이 없이 산발적으로 발생한다. 또한 검사실 소견에서도 특징적인 소견은 없다. 진단은 임상적인 소견을 바탕으로 이루어지며, 장기적인 합병증을 남기지는 않는다. 현재까지 알려진 치료로는 경구프레드니솔론이 증상을 조절하는 데 효과적이라고 알려져 있다. 저자들은 2년간의 임상 증상의 반복을 경험하였던 6세 여아에서 다른 질환을 배제한 후 PFAPA 증후군의 진단 요건을 만족하여 경구 프레드니솔론을 사용한 후 증세의 호전을 보인 PFAPA 증후군의 한 예를 보고하고자 한다.

The morphology and mechanical properties of the blends of a syndiotactic polystyrene (SPS) and poly-styrene-block-poly(ethylene-co-butylene)-block-polystyrene copolymers (SEBS) with various polystyrene block contents are studied. Mechanical properties, especially elongation at break and impact strength (IS), of the blend depend upon the morphology and interfacial adhesion, which in rum are affected by the viscosity ratio of constituent components and the styrene block content in SEBS. The IS of a blend was affected by the combined effect of rubber content and the interfacial adhesion. A maximum IS was found for a blend with the weight fraction of the PS block in an SEBS of 0.18. The IS of blends with smaller weight fractions of the PS block exhibited lower due to poor interfacial adhesion between SPS/SEBS in spite of a larger amount of rubber block. On the other hand, the IS of blends with larger weight fraction of the PS block becomes smaller due to lower amounts of rubber block in spite of better interfacial adhesion.

Degradations of pine, yellow poplar and sweet gum by two fungi, Pycnoporus cinnabarinus and Trichophyton rubrum LSK-27 were investigated. P. cinabarinus degraded pine block samples much faster than T rub rum LSK-27, whereas P. cinnabarinus and T rubrum LSK-27 degraded yellow poplar and sweet gum at almost the same rate. In an effort to get a better understanding of how fungi degrade lignin in wood, contents of various functional groups were analyzed. After three-months of degradation of pine flour by these fungi, the following changes were observed: an increase in condensed phenolic OH group and carboxylic acid group content, a decrease in the guaiacyl phenolic OH content, and little change of aliphatic OH group content. Further studies in the degradation of pine flour by P. cinnabarinus indicated that the increase in condensed phenolic OH group content and the decrease in guaiacyl phenolic OH group content occurred in the first month of the degradation. The changes of functional group contents in the degradation of unbleached softwood kraft pulp by P. cinnabarinus had the same trends as those in the degradation of pine flour. That is, structural alteration of lignin due to the kraft pulping process had little effect on how P. cinnabarinus degraded lignin.

The theory of random utility maximization (RUM) defines the probability of an alternative being chosen as the probability of its utility being perceived as higher than those of all the other competing alternatives in the choice set (Marschak 1960). According to this theory, consumers perceive the utility of an alternative not as a constant but as a probability distribution. Over the last two decades, there have been an increasing number of studies on the effect of utility variance on choice probability. The common result of the previous studies is that as the utility variance increases, the effect of the mean value of the utility (the deterministic component of the utility) on choice probability is reduced. This study provides a theoretical investigation on the effect of utility variance on choice probability without any assumptions on the specific forms of probability distributions. This study suggests that without assumptions of the probability distribution functions, firms cannot apply the marketing strategy of maximizing choice probability (or market share), but can only adopt the strategy of maximizing the minimum or maximum value of the expected choice probability. This study applies the Chebyshef inequality and shows how the changes in utility variances affect the maximum of minimum of choice probabilities and provides managerial implications.

Objective: This study aims to analyze occupational accidents of parking lot attendants by parking lot type. Background: Recently, efforts are made to analyze accident characteristics by occupation type targeting the workers engaged in the same work. Method: This study analyzes 303 occupational accidents of parking lot attendants occurring from 2010 to 2012. Parking lots are grouped into two groups according to the work environment. One is public/ground type which comprises road side or open area parking lots and the other is building/mechanical type which comprises a multi-story parking building with connecting ramps and/or mechanical parking system. The characteristics of occupational accidents by parking lot type are analyzed. Results: Accident characteristics showed the difference between public/ground type and building/mechanical type on the size of enterprise, age, gender and work experience of the injured. Also the accident type, source of accident and parts of body affected are different between the two parking lot types. Conclusion and Application: The findings of accident characteristics according to parking lot types can be used as baseline data for establishing systemized preventative policies for occupational accidents of parking lot attendants.
