피조개 발의 조직학적 구조는 hematoxylin-eosin염색 및 Weigert iron hematoxylin염색을, 점액질 성상을 검색하기 위하여 PAS반응, diastase 침지 후 PAS반응, alcian blue pH 2.5염색, alcian blue pH 1.0염색, alcian blue pH 2.5-PAS염색, alcian blue pH 1.0-PAS염색, aldehyde fuchsin pH 1.7-alcian blue pH 2.5염색 및 0.25% toluidine blue염색을 실시하였다. 피조개의 발은 상피, 상피하결합조직 및 근층으로 이루어져 있었으며 상피는 단층섬모원주세포로 되어 있었다. 상피하결합조직 및 근층에 다세포성 점액선인 발선이 발달되어 있었고 도관은 결합조직과 상피세포를 거쳐 개구되어 있었다. 근층은 종주근, 수직근 및 횡근섬유로 구성되어 있었다. 점액질의 조성을 보면 상피세포섬모에는 sialomucin만을, 상피세포는 중성점액질만 함유하고 있었다. 상피세포 및 결합조직내 점액도관에는 산성과 중성점액질의 혼합성인 것과 산성점액질만 함유한 것이 혼재하나 전자가 더 많았다. 산성점액질의 성상으로 보아 대부분이 강 sulfomucin을 가지며 일부는 약 sulfomucin과 sialomucin의 혼합성이었다. 대부분 발선의 점액선포에 대한 점액질 조성은 점액도관과 유사하였으나 일부 상부발선의 점액선포는 중성점액질만을, 하부발선의 점액선포는 sialomucin만을 함유하였다. This study was performed to investigate the histological structure and the histochemical properties of the mucosubstances in the foot of Anadara broughonii. For the histological structure, hematoxylin-eosin and Weigert iron hematoxylin staining were used. The mucosubstances stained with PAS, PAS-diastase, 0.25% toluidine blue, alcian blue pH 2.5, alcian blue pH 1.0, alcian blue pH 2.5-PAS, alcian blue pH 1.0-PAS, aldehyde fuchsin pH 1.7-alcian blue pH 2.5 methods. The foot was composed basically of three layers: epithelium, subepithelial connective tissue and muscular layers. The foot was lined by simple ciliated columnar epithelial cell. Foot glands consisted of multicelluear mucous acini were present in the subepithelial connective tissue and muscular layer. The mucous duct of foot glands was distributed from connective tissue to epithelial cells, and open onto the surface of the foot. The foot muscle traveled in three planes as longitudinal, transverse and vertical muscle fiber. About the properties of mucosubstances on the foot, cilia of epithelial cell contained sialomucin only and epithelial cell neutral mucosubstances only. Most of mucous duct within epithelial cells and connective tissue showed a mixture of acidic and neutral mucosubstances, while a few mucous ducts were contained acidic ones only. Among acidic mucosubstances, notable strong sulfomucin were found in most mucous cell of duct, and a mixture of weak sulfomucin and sialomucin appeared in a few cells. The properties of mucosubstances in the food glands were similiar to those of mucous duct. But a few mucous acini contained neutral mucosubstances and sialomucin only in upper and lower portion of foot gland, respectively.

It is proposed that the rotor time constant and inductance are compensated at the same time in the indirect vector control method of induction motor. The proposed scheme compensates the rotor time constant using the difference between Q-axis real stator current and estimated current that is calculated from terminal voltage and current, and compensates inductance using the difference between D-axis real stator flux and estimated stator flux in synchronous rotating reference frame. Although the rotor time constant and inductance vary at once, the proposed method compensates the rotor time constant and inductance with accuracy. In addition to, two variables cna be compensated not only at steady state condition, but also at transient state, where torque varies in rectangular pulse waveform. Therefore performance of vector control is improved highly and it is verified by experiment.

As the internationalization of enterprising business enlarged the extent of intervention of enterprises, the importance of world market in the enterprising business is growing every day. Multinational enterprises that target the world market have to determine whether they should adapt the marketing mix strategy to each country or standardize it universally. The controversy on the standardization or the adaptation of strategy is especially active in the field of products and advertising. Since the possibility of standardization of multinational advertising which is an essential component of marketing mix insisted by Elinder in early 1960, the controversy on this matter in 1980's. Levitt refuted the argument of adaptation and maintained that the consumers in the world have been homogenized by the development of technology. Thus multinational advertising not only establishes the universal image of specific products but it also reduces the production costs of advertising. The subject that the advertising strategy of Korea applies to other countries should be studied seriously for the provision against the fact that Korea has become a leading exporter and that the advertising of Korean brands will be exposed in the near future. This study will survey the controversy on the standardization versus customization of multinational advertising among many researchers. It will present a conceptual model of the standardization of advertising through the scientific and theoretical approach to advertising. It will also present to the consumer an interdisciplinary approach to the method of comparison.

This paper is an attempt to propose our study that draw up a plan about faculty and major course to the Daegu Polytechnic College authorities. Our approach is a mixture of methods. It is systematic, in that it attempts to treat a college as a system. Through the second chapter, we examine the periodic, social, environmental, governmental, and economic context within which the College's developing effort must progress. Chapter three examines how the college systems actually design about faculty and major course. Thus, chapter four discusses how new faculty and major course participants attempt to compose a curriculum; chapter five accesses the institutions available in the College to distribute these designs. In conclusion, this paper presents that the College system would be better nine faculty; education and nurse·health field only be in administration unit, an information field be better divided into two parts: internet computer and information communication, and business and computer design faculty is established as intimate information. After all, the system will be characteristic in its information traits.

Digital technical renovation and rapid development of internet and super communication technologies have dramatically influenced on trends of our society over the cyber space and college is necessary to be reformed against such current innovation to keep up with advanced technologies and skills for digital and communication fields. For this reason, initial efforts were focused on extending development of infra structraul systems to operate efficient recruitment of enterance college, college advertisement, educational strength, industrial-educational cooperation, job oppertunities, financial support which are currently confronted with. Such efforts also can be alternative way to be a future direction as long-term plans of our college. In this report, we suggest plan for collective and long-term schemes against current college problems Moreover, even though a proposed plan as first step is to limit to Susung-Ku area, this system for practical application and harmony can be applied to other county areas without any additional investment and efforts in the future.
