Ahn, Hyunkee, Soon-Suk Kwon, and Ki-Yeol Kim. 2000. Obstruent Nasalization: Its Phonology and Phonetics. Linguistics 8-1, 27-38. This paper discusses a Korean phonological rule, Obstruent Nasalization--i.e., an obstruent is phonologically nasalized when followed by a nasal. As is well known, this rule is productively prevalent in Korean, but not in English. Within the Optimality Theoretic framework, the difference in this phonological pattern between the two languages is well captured by means of adjusting the dominance relationship between two constraints (markedness and faithfulness constraints). This constraint-based explanation, however, doesn't suffice our question of why the phenomenon is phonetically natural in Korean, but cross-linguistically rare. To this question, we will provide one possible answer by suggesting that the markedness constraint is phonetically oriented due to a phonetic constraint on laryngeal feature juxtapositions.

In the domestic food service market, consumers' behavior is becoming higher, diversified, and individualized due to the increase in income due to economic development, and the proportion of the food service industry is gradually increasing as the change in diet is accelerated. The fast-food industry, one of the fastest growing segments of the food service industry, has been rapidly supplied to busy urban people and students who are being chased in time, at an affordable price, and their demand is soaring. Among them, pizzeria is steadily loved, and as the scale is large, the competition among the companies is not endless. In this situation, customers are also subdivided and diversified, making choices based on the various attributes of the pizza restaurant. With such multi-attribute criteria and differentiation, customers should be aware of unique and symbolic images that distinguish them from other brands. Therefore, it is necessary to provide a logical basis for predicting and preparing consumers' preference through AHP, which is a research and analysis according to attributes (reliability, comfort, brand, service). We suggest pizza marketing plan because it is deemed necessary, and we plan to cope with consumer's needs.

Since our coutry has in sufficient natural resources, and water covers about 70% of the earth's surface, we must take advantage of our country being a peninsula, and internationalize by marine transportation. However, fuel costs are high, because fossil fuel deposits are limited and oil producting countries are closely banded together. Also, fuel emissions pollute the air throughout the world. Pollution levels for specific gases include 2% for CO2, 4% for SOx, and 7% for NOx. By the way, nuclear power is suitable as a high output power source due to its low cost and its use for powering ships is profitable because of its light weight and small volume. Also, it is most suitable as a power source in water, because it can be used for long term operations, and because oxygen is not necessary for combustion. In the future, if the safety of the marine reactor is made sure by its simplicity and technical development for automation. nuclear power will prove to be the means for future growth in marine transportation. It call be used to power vessels used as ice breakers, and can also be used for deep sea operations, especially submarines used for investigation and resource development. Therefore, I want to study the characteristics of the marine reactor compared with the power reactor, because marine reactor can be used in narrow space and are affected by ocean states. The contents I want to study are as follows. (1) Passive high safety (2) Suitability for various loads (3) Pursuit of small size

Decision analysis has becomes an important technique for decision making in the face of uncertainty. It is characterized by enumerating all the available courses of action, identifying the payoffs for all possible outcomes, and quantifying the subjective probabilities for the all possible random events. When the data are available, decision analysis becomes a powerful tool for determining an optimal course of action. In this paper, we use the analytic hierarchy process in weights calculating. For the purpose of making optimal decision, the data of three different smart phones models are used.

Because lightweight concrete with expanded polystyrene beads has properties of low density, low heat conductivity, it can be used in lightweight structural material and heat insulation layer. But application of this material in buildings is insufficient yet. One of application in building is panel, like non-structural partition used inside, has low compressive strength. So the purpose of this study is to lead the fundamental data to improve low strength of lightweight concrete with polystyrene beads by mixing silica fume and curing methods for application to dry lightweight panel of building, which is based on the mechanical property of lightweight concrete using polystyrene beads, and to examine suitability of polystyrene beads as composition material of panel from the above result. Unit volume weight of fresh concrete is 0.5-0.61t/m³ in EPSB substitution rate 70% and 0.27 -0.33t/m³ in EPSB substitution rate 80%, and compressive strength as increase of silica fume substitution rate is increased but, batch in EPSB substitution rate 80% has low compressive strength rate. Compressive strength by curing method was higher by high temperature(60˚C, seal up).

냉이를 대상으로 채취시기 및 토양의 비옥도에 따른 휘발성 풍미성분 변화패턴을 조사한 결과 동일 지역에서 채취한 시료라도 채취시기에 따라 휘발성 풍미성분 저상에 차이가 있음을 확인하였다. 마석 지역에서 3월에 채취한 냉이에서는 총 50종의 성분이, 4월에 채집된 냉이에서는 총 58종의 성분이 확인되었다. 구성 성분의 차이이외에 같은 성분이라도 양적인 측면에서 상이하였다. 야생식물의 휘발성 풍미성분의 조성 및 함량의 차이는 일조량, 강우량 및 기온 등의 여러 가지 환경요인에 의한다고 측정되며, 이러한 환경요인에 대해서는 앞으로 계속 규면되어야 할 것이다. 토양의 비옥도에 따른 휘발성 풍미성분의 변화패턴을 조사하기 위하여 강원도 춘천 지역에서 토양의 질이 좋은 밭과 일반 들판에서 같은 시기에 채취한 냉이를 분석한 결과 휘발성 풍미성분의 profile이 다를 뿐만 아니라 들판에서 채취한 냉이에서는 19종의 휘발성 풍미성분이 더 확인되었다. 냉이를 대상으로 채취시기 및 채취지역에 따른 유리 및 전 아미노산의 함량을 조사한 결과 양적인 측면에서 큰 차이를 보였으며, 강원도 춘천의 토양이 비옥한 밭에서 채취한 시료가 일반 들판에서 채취된 냉이에 비하여 유리 및 아미노산의 함량이 월등히 높았다. These studies were performed in order to determine the volatile flavor components and contents of amino acids in total and free forms from Capsella bursa-pastoris. Volatile flavor components from Nangi (냉이 ; Capsella bursa-pastoris) were collected by simultaneous steam distillation-extraction(SDE) method. Essential oils were analyzed by gas chromatography(GC) and combined gas chromatography-mass spectrometry(GC-MS). Amino acids were identified and quantified by automatic amino acid analyzer. Emphasis was given to the effects of collecting time and growing regions on flavor components from this wild plant. As a result of confirming essential oils of Capsella bursa-pastoris collected from MaSeok region in early spring(March) and middle spring(April), the kinds and amounts of volatile flavor components revealed different patterns depending upon collecting time. Respective 50 and 58 volatile flavor components were confirmed in samples of Capsella bursa-pastoris collected in early spring and middle spring. Samples of Capsella bursa-pastoris collected from open field in ChunCheon region showed a greater number of volatile flavor components than the ones collected from ordinary field. Sixteen kinds of amino acids were identified and quantified, that is aspartic acid, threonine, serine, glutamic acid glycine, alanine, valine, methionine, isoleucine, leucine, tyrosine, phenylalanine, lysine, histidine, arginine and proline, Fifteen kinds of free were identified. Capsella bursa-pastoris collected from ordinary field in ChunCheon region contained larger amounts of total and free amino acids than any other samples. The amounts of total and free amino acids revealed different patterns depending upon collecting time and growing regions.

The purpose of this study is to investigate the kinematical variables of the Tkatchev of the Tkatchev motion on the horizontal bar and the effects of kinematical variables of l phase on 2. 3. 4 phases and the effects of kinematical characteristics of every phase on motionin the air and re-grasping. The subjects" Tkatchev motion were filmed with S-VHS camera at the speed of 8 fields per second and each field is digitalized to 5 fields from the start of handstand motion to landing. The Kwon 3D 2.1 version program is employed to obtain 3-dimensional data. Based on the results of this study, the Following conclusions are drawn: 1. In the Down swing phase. the maintenance of great vertical downward velocity is an important variable to achieve large angular velocity of body center and is id also proved that the fast downward motion gives advantage in spreading body joints to get great motion power in the next Whip swing motion. 2. In the Whip swing phase. fast upward velocity and fast angular velocity of hip joint will positively affect upswing movement in the phase. To shorten the distance between horizontal bar and body center helps effective upward motion as well. These also work beneficially in the next phase. 3. In the Releases phase. fast vertical upward velocity until pull back after curving shoulder joint and hip joint at the whip swing and large change of position of body center are important variables to perform high and long flight duration. 4. In the Re-grasp phase. the maximum spread of shoulder joint and hip joint and the spread of body center to the opposite direction of it helps body center to stay in higher place and to perform large circular flight motion with extended length of time. This ultimately makes effective re-grasping motion happen and connects next motion smoothly. In summary, it is desirable to move by using gravity power and maximize inertia by keeping body center away from horizontal bar and then achieving higher position in the phase four movement by moving upward fast which allows longer time of motion with power achieved fro, the inertia then just to move reverse by using shoulder joint and hip joint. To achieve this desirable movement, the velocity of body center needs to fast in the swing phase, but, on the contrary, in the Releases phase, nearly stalled movement make it eaes to circulate revers in the air. Also, to get by dramatic and desirable motion. body center must be in higher position by doing large circular excercise including not only vertical movement but also horizontal movement. 2. Suggstion This study is about the investigation of kinematical variables in Tkatchev motion by utilizing three-dimensional cinematographic method. The result of this study has a limitation in that it is drawn from an experimental situation and only with 10 male subjects. It is expected that another study deals with gymnastics motions more then more enlarged subject groups resulting in the contribution to the improvement of game techniques and training.
