A holographic demultiplexer aimed at producing low polarization dependence loss using a long period volumetric diffraction grating inside photopolymer has been reported and experimentally demonstrated. To obtain the long period gratings, two kinds of gratings are recorded by angle of $4^{\circ}\;and\;6^{\circ}$ corresponding to the polarization dependence property of below 0.5 dB. From the experimental results, we demonstrate the 0.8 nm-spaced 21 channel holographic demultiplexer with the polarization dependence loss of less than -0.38 dB, the channel uniformity of 0.495 dB, and the channel crosstalk of -13 dB.

The Gate-Induced-Drain-Leakage (GIDL) current with channel doping and width dependence are characterized. The GIDL currents are found to increase in MOSFETs with higher channel doping levels and the observed GIDL current is generated by the band-to-band-tunneling (BTBT) of electron through the reverse-biased channel-to-drain p-n junction. A BTBT model is used to fit the measured GIDL currents under different channel-doping levels. Good agreement is obtained between the modeled results and experimental data. The increase of the GIDL current at narrower widths in mainly caused by the stronger gate field at the edge of the shallow trench isolation (STI). As channel width decreases, a larger portion of the GIDL current is generated at the channel-isolation edge. Therefore, the stronger gate field at the channel-isolation edge causes the total unit-width GIDL current to increases for narrow-width devices.

The aim of this paper is to investigate the women's apparel distribution channel in the well-known department stores located in the central Seoul area. Since the department store has its reputation, information and enormous buying power, it is the one of the major leading retails in the women's apparel industry. In doing so, the relationship between the channel members in terms of the level of dependence, power sources and perceived conflict and manifest conflict has been studied. Particularly, based on French and Raven's power sources, position source is added. It refers to a channel member's (Merchandizer in the department store) source over another based on the expection the former (Merchandizer in the department store) will be able to allocate the location and size of the store influencing the latter's sale and profit. The key informants are the merchandizers who work in the apparel companies contracting with major department stores. Finally, of the 284 questionnaires collected, 235 are usable. The hypotheses are tested through LISREL. The results of statistical analysis support that : Dependence has a positive effect on noncoercive bases of power. Coercive bases of power have a positive effect on manifest conflict as well as perceived conflict while noncoercive bases of power have a negative effect mainly on manifest conflict. Thus, the relation between the major department stores and the women's apparel companies in there seems to have bilateral dependence rather than highly unilateral dependence.

The Purposes of this study ar (1) to identify types and levels of channel conflicts between an apparel manufacturer and a franchised agency, (2) to investigate the effect of economic dependence on conflicts, and (3) to examine the effect of conflicts on satisfaction in a franchised agency's perspective in distributive channel of Korean apparel industry. For this study, questionnaires were administered to the owner or manager of 300 franchised agencies. Employing a sample of 209, data were analyzed by using means, factor analysis, pearson correlation and multi-regression analysis. Major findings are as follows: 1) Types of conflicts between apparel manufacturers and franchised agencies are identified as goal divergence, difference in perception, ineffective communication and lack of role clarity. The highest level of conflicts are lack of role clarity, followed by goal divergence, difference in perception and ineffective communication. 2) Economic dependence leads to channel conflicts in part. Greater levels of economic dependence foster greater conflicts such as lack of role clarity and lower conflicts such as ineffective communication. 3) With respect to effect of conflict on satisfaction, the greater the levels of conflict, the lower the degree of satisfaction with ole performance and with business decision and overall satisfaction.

Numerical calculation for temperature dependence of galvanomagnetic properties of thin bismuth films is pursued. The quasi-two dimensional system is treated in the perturbation formalism of previous study, where realistic screened potential due to impurity is assumed to be the only scattering channel. The potential is separated into pure two dimensional part and the remaining presumed perturbation part. Relaxation time and mobilities for both electron and hole are evaluated, then temperature dependence of the Hall coefficient and magnetoresistance is obtained. The broad minimum of magnetoresistnace is manifested, and the interpretation under the kinetic theory is made. Thickness dependence of the quantities are also shown, which are in good agreement with the expected quantum size effect.

In this paper, we investigated the dependence of device performance and hot carrier lifetime on the channel direction of PMOSFET. $I_{D.sat}$ vs. $I_{Off}$ characteristic of PMOSFET with <100> channel direction is greater than that with <110> channel direction because carrier mobility of <100> channel direction is greater than that of <110> channel direction. However, hot carrier lifetime for <110> channel direction is much lower than that with <110> channel due to the greater impact ionization rate in the <100> channel direction. Therefore, concurrent consideration of reliability characteristics and device performance is necessary for channel strain engineering of MOSFETs.

Channel length dependence of NBTI (negative bias temperature instablilty) and CHC (channel hot carrier) characteristics in PMOSFET is studied. It has been considered that HC lifetime of PMOSFET is larger than NBTI lifetime. However, it is shown that CHC degradation is greater than NBTI degradation for PMOSFET with short channel length. 1/f noise and charge pumping measurement are used for analysis of these degradations.

The objectives of this study are to conceptualize theoretically and to examine empirically the interrelationships among channel member's satisfaction, dependence, and performance being immanent between dealing partners, by integrating behavioral and economic approach to explain comprehensively the interrelationship between dealing partners in conventional marketing channel which have not studied in previous studies. To attain above objectives, latent variables and observed variables which had been immanent between licenced dealers and wholesalers in fish marketing channel were found out by exploratory study, and pre-test was conducted to select the proper variables, and then the model which could explain the interrelationships among the variables was set up. Three categories of varables were considered in this study. Namely, economic and noneconomic factors were identified as independent variable, the degree of satisfaction and dependence to dealing partner as intervening variable, and performance as dependent variable. The data for the study was obtained from a survey questionnaire of 214 licenced dealers who work in Pusan, Yusoo, and Kunsan and 190 wholesalers who work in whole country. Among them, 264 anayzable questionnaires(including 154 licenced dealers and 110 wholesalers)were collected. Statistical procedure to analyze the data was carried out by LISREL version 7. Major findings obtained from the results of the analysis are as follows. First, economic variables have a great influence on the degree of both licenced dealers' and wholesalers' satisfaction. Among economic variables, the degree of keeping wholesalers' payment date have greater influence on the degree of licenced dealers' satisfaction, and licenced dealers' faculty being able to send good fish in quality have greater influence on the degree of wholesaler's satisfaction than other variables. In short, licenced dealers make great account of wholesalers' payment, and wholesalers make great account of licenced dealers' faculty being able to send good fish in quality in dealing relationship. Second, noneconomic variables have more relevance to the degree of dependence in both sides than economic variables. This means that noneconomic variables as well as economic variables can be a factor to keep up the dealing relationship. Third, the degree of satisfaction and dependence have influence on performance in both sides. In the licenced dealers' side, the degree of dependence have greater influence on performance than the degree of satisfaction, on the other hand, in wholesalers' side, the degree of satisfaction have greater influence on performance than the degree of dependence. This means that wholesalers can easily substitute their dealing partner for another licenced dealer comparatively.

Nature of magnetic creep phenomena in low coercive force films(Ni 80%-Fe 20%) in form of narrow channels imbedded in high coercive force films is studied in this work. Aluminium is evaporated on the hot glass substrate and eched free in the shape of narrow channels by photoetoetching method. then, Permalloy(Ni 80%, Fe 20%) is deposited on these Aluminium substrate under the uniform field of 30(Oe) to introduce anisotropy. Permalloy film on Al has a high coercive force and one on the substrate devoid of Al has how coercive force. Magnetic revers domain which is introduced at the end of channel grows under the a.c field in hard axis direction, in spite of very weak d.c field in easy axis direction. This creeping is investigated as a function of external fields and channel widths. Permalloy film thickness is 500.angs.-900.angs. and channel widths are 40, 51, 65, 81, 115.mu. respectively. Creeping increases as external field increases while it decreases with channel width decrease. Creep velocity in channels depends on the a.c field along hard axis, d.c field along easy axis and channel widths and its range is 1-10cm/sec in this experiment. From study of dependence of creep velocity on channel width, it can be concluded that creep velocity is expressed in form of v=v$_{0}$ exp .alpha.(H-H$_{0}$) where .alpha. is a function of a.c field along hard axis and H is driving d.c field along easy axis, H$_{0}$ is not a coercive force of film as usuall expected but the d.c threshold field along easy axis which is a function of channel width. This characteristic is also confirmed by the study of dependence of creep velocity upon easy axis field strength. Value of .alpha. obtained is 1.3-2.3cm/sec We depending upon film charactor, hard axis field strength and frequency.uency.
