This study aims to present suggestions on the causes and effects between internal marketing and customer-oriented trends of social welfare halls based on the issue that internal marketing should be activated based on previous studies on the relationship between internal marketing and customer-oriented trends. For this purpose, as a result of analysing the research hypothesis through a questionnaire, this study has meaning in that it supported the results of previous studies on internal marketing and customer-oriented trends as theoretical suggestions and analysed the relationship between internal marketing and customer-oriented trends. It was politically suggested and emphasized that internal marketing is needed in social welfare halls and to encourage social welfare workers to be customer-oriented, components of internal marketing should be established in an organic and systematic manner.

The formation and thermal properties of the $BaO_2$ and $TiO_2$ mixtures were prepared by mechanical alloying method was investigated by X-ray diffractometry (XRD), scanning electron microscopy (SEM), and thermogravimetric/differential thermal analysis (TG/DTA). The rotating speed of 750 rpm shows more effects on the formation of $BaTiO_3$ single phase. The internal strain calculated using Williamson-Hall method was $4.27{\times}10^{-3}$ for the mixture milled for 300 min, the crystallite size was calculated using the Scherrer method decreased with milling time. The $BaTiO_3$ crystal improved crystallinity was formed by thermal annealing at a temperature of $600^{\circ}C$ for 1 h for the mixture milled for 300 min.

AI doped ZnO (AZO) films, and intentionally Zn added AZO (ZAZO) films were prepared on Corning glass by rf magnetron sputtering, and the electrical, optical, and structural properties of the as-deposited films together with the air annealed films were investigated. The resistivity of the AZO films increased with increasing substrate temperature and having minimum resistivity at $150^{\circ}C$. At the high temperature, the ZAZO films showed improved electrical properties better than the AZO films due.to increase in both the carrier concentration and.the Hall mobility. Upon air annealing at $500^{\circ}C$, the resistivity of both AZO and ZAZO films increased substantially, but the relative amount of degradation was smaller for films deposited at $450^{\circ}C$ than the films deposited at $150^{\circ}C$.

In the present paper, we have considered a layered medium of two semi-infinite nonlocal elastic solids with intermediate transversely isotropic magnetothermoelastic solid. The intermediate slab is of uniform thickness with the effects of two temperature, rotation and Hall current and with and without energy dissipation. A plane longitudinal or transverse wave propagating through one of the nonlocal elastic solid half spaces, is made incident upon transversely isotropic slab and it results into various reflected and refracted waves. The amplitude ratios of various reflected and refracted waves are obtained by using appropriate boundary conditions. The effect of nonlocal parameter on the variation of various amplitude ratios with angle of incidence are depicted graphically. Some cases of interest are also deduced.

In the present investigation, a plane P (longitudinal) wave is made incident upon a transversely isotropic magnetothermoelastic solid slab of uniform thickness, interposed between two different semi-infinite viscoelastic solids. The transversely isotropic magnetothermoelastic sandwiched layer is homogeneous with combined effects of two temperature, rotation and Hall current in the context of GN Type-II and Type-III (1993) theory of thermoelasticity. The amplitude ratios of various reflected and refracted waves are obtained by using appropriate boundary conditions. The effect of energy dissipation on various amplitude ratios of longitudinal wave with angle of incidence are depicted graphically. Some cases of interest are also deduced from the present investigation.

This study examines the effects and influences of fumigation using chemical composite of Methyl Bromide and Ethylene Oxide on the change of strength of excavated dresses. The fabric strength immediately after washing and fumigation increased slightly, but it decreased greatly as the time progressed. The strength of the test sample from Museum A showed a steady decrease with time, while that of Museum B decreased rapidly 5 months later. Compared with the non-fumigated sample, fumigated sample was greater in strength regardless of the time progression, and the strength of sample kept in the exhibit hall was greater than that kept in the storage room. The strength of the fumigated sample was almost same regardless of the three different time periods, before washing, after washing and immediately after fumigation, and it decreased steadily with time, whereas the non-fumigated sample became much weaker in its strength in 10 months after washing. Even 5 months later, the fumigated sample was about as strong as immediately after fumigation, but the strength dropped to a great extent 10 months later.

Local polynomial regression is widely used because of good properties such as such as the adaptation to various types of designs, the absence of boundary effects and minimax efficiency Choi and Hall (1998) proposed an estimator of regression function using a convex combination idea. They showed that a convex combination of three local linear estimators produces an estimator which has the same order of bias as a local cubic smoother. In this paper we suggest another estimator of regression function based on a convex combination of five local constant estimates. It turned out that this estimator has the same order of bias as a local cubic smoother.

WSi$_{x}$박막을 Polycide구조로 저압화학증착법에 의해 제작한 후, 열처리를 N$_{2}$분위기에서 30분간 여러온도로 수행하였다. WSi$_{x}$박막의 전기비저항은 열처리온도의 증가에 따라 감소하였으며 1000.deg.C이상으로 열처리한 시편의 경우, 하부 다결정실리콘층의 도우핑여부에 관계없이 35.mu.m.OMEGA.-cm 정도를 나타내었다. 560.deg.C의 열처리에서 WSi$_{x}$박막은 정방정의 WSi$_{2}$ 결정질로 결정화가 되기 시작하였고 열처리온도의 증가에 따라 WSi$_{2}$결정립의 성장도 관찰되었다. 열처리온도에 따른 전기저항의 변화는 WSi$_{x}$박막의 결정립크기와 밀접한 관계가 있었다. 증착된 WSi$_{x}$박막내의 광잉실리콘원자들이 열처리중에 하부의 다결정실리콘층으로 재분배됨을 AES분석에 의해 확인하였다. Hall 측정결과 900.deg.C이상으로 열처리된 시편은 Hole도전체의 거동을 나타내었고 800.deg.C이하로 열처리된 시편은 electron도전체의 거동을 나타내었다.

Many compound semiconductors which have high carrier mobility and small band gap have attentive in application of various practical a field. Especially, InSb served for Hall device and magnetic resistor such as magnetic sensor because InSb thin film has high mobility. Many studies on InSb thin film deposistion because In and Sb has been very different feature of vapor pressure($10^{-4}$ times) When In and. Sb deposited. In this paper studied it In and Sb deposited simultaneously using by method of co-sputtering deposotion. This process, get to effects of manufacture process simplification. After that this paper observed micro structure and electronic behavior of InSb thin film using by co-sputtering and we study properties of magneto-resistance by annealing
