As Chinese political and economical status gets higher, a lot of multinational firms have tried to find some chances from the Chinese market successfully. Though geographically Korea is located closely to China, a lot of firms entering into Chinese market have turned out failed. Thus, this study researched Korean manufacturing firms in China, surveyed their localization degree of distribution, and tried to find out factors which influence these localization from a far-reaching literature. As a result of analyzing 146 questionnaires, the length of channel, among Chinese environmental factors, has a positive influence on the distribution localization degree. In addition, the factor of distribution relation assets has a positive effect on the distribution localization degree. Considering this study, the Chinese market, especially distribution field, has recently grown up to the world-class level. Therefore a firm intending to enter into China needs to be careful not to underestimate China.

The purpose of this paper is to empirically analyze the determinants of foreign subsidiary's local embeddedness because it is critically important for the subsidiary to build a variegated local network. This paper suggests that a MNC's global capability, the degree of autonomy granted by the headquarters of the multinational corporation to its foreign subsidiary, the foreign subsidiary's absorptive capacity based on local environment, and its level of localization will affect the subsidiary's local network embeddedness. The empirical analysis confirmed that when the headquarters gives the foreign subsidiary more autonomy, this has a positive effect on the local embeddedness of the foreign subsidiary and when the foreign subsidiary has a strong absorptive capacity, this has a positive correlation with the local embeddedness of the foreign subsidiary. And this paper found that when the foreign subsidiary has achieved a high level of staff localization, this foreign subsidiary will have a higher level of local embeddedness. This study identified the preceding conditions necessary for a foreign subsidiary of a multinational corporation to effectively embed itself in the local network by analyzing factors related to the multinational corporation's headquarters and subsidiaries, and thus contributes significantly to continued research on the local embeddedness of subsidiaries.

The purpose of this study was to propose a new approach for quantifying in situ rock mass damage, which would include a degree-of-damage and the degraded strength of a rock mass, along with its prediction based on real-time Acoustic Emission (AE) observations. The basic approach for quantifying in-situ rock mass damage is to derive the normalized value of measured AE energy with the maximum AE energy, called the degree-of-damage in this study. With regard to estimation of the AE energy, an AE crack source location algorithm of the Wigner-Ville Distribution combined with Biot's wave dispersion model, was applied for more reliable AE crack source localization in a rock mass. In situ AE wave attenuation was also taken into account for AE energy correction in accordance with the propagation distance of an AE wave. To infer the maximum AE energy, fractal theory was used for scale-independent AE energy estimation. In addition, the Weibull model was also applied to determine statistically the AE crack size under a jointed rock mass. Subsequently, the proposed methodology was calibrated using an in situ test carried out in the Underground Research Tunnel at the Korea Atomic Energy Research Institute. This was done under a condition of controlled incremental cyclic loading, which had been performed as part of a preceding study. It was found that the inferred degree-of-damage agreed quite well with the results from the in situ test. The methodology proposed in this study can be regarded as a reasonable approach for quantifying rock mass damage.

The development of embryos reconstructed by somatic cell nuclear transfer (SCNT) is dependent upon numerous factors. Central to development is the quality and developmental competence of the recipient cytoplast and the type of the donor nucleus. Typically metaphase of the second meiotic division (MII) has become the cytoplast of choice. Production of a cytoplast requires removal of the recipient genetic material, however, it may remove proteins which are essential for development or reduce the levels of cytoplasmic proteins to influence subsequent reprogramming of the donor nucleus. In this study, enucleation at MII did not affect the activities of either MPF or MAPK kinases. Immunocytochemical staining showed that both Cyclin B1 (MPF) and Erk1/2 (MAPK) were associated with the meiotic spindle of AI/TI oocytes with little staining in the cytoplasm, however, at MII association of both proteins with the spindle had reduced and a greater degree of cytoplasmic distribution was observed. The analysis of oocyte proteins removed during enucleation is a difficult approach to the identification of factors which may be depleted in the cytoplast. This is primarily due to the large numbers of aspirated karyoplasts which would be required for the analysis.

This study was an attempt to investigate various factions, such as the calorie, nutrient intake, physical activity, blood lipids, obesity prevalence and body fat distribution on NIDDM male diabetics. General characteristics, physical activity and exercise levels of subjects were invesigated by interviewing, daily calorie and nutrient intake were measured by convenient method. The following anthropometric measurements were made on all participats : weight, height. Also waist and hip circumference were measured on 174 male diabetics to get waist-to-hip circumference ratio as index of the body fat distribution. For measurement of plasma lipids, 12-hour fasting blood samples were drawn The results of this study were summarized as follows : 1. At the onset of diabetes, the major self-diagnosed symptoms were polydipsia, fatigue, and body weight redution 2. The average of daily energy intake of male diabetics was 2106 Kcal which is 96% of the RDA Percentage of energy is that carbohydrate:protein : pat=70:14:16. 3. Among the NIDDM male subjects, 59% was exercise regularly. 4. Obese subjects above in the ideal body weight of 120% are presently 17%, but 39% of subjects were reported to be obese in the past. The mean BMI of the male NIDDM diabetics is 23.3${\pm}$2.6 and the past mean BMI was 25.2${\pm}$2.7 The mean WHR was 0.93${\pm}$0.10. 5. When diabetics were divided into obese and nonobese group according to RBW, energy intake, blood pressure, blood glucose and total cholesterol were not significantly different between the two groups, but LDL and VLDL-cholesterol were significantly higher in the obese group. 6. RBW did not correlate with cholesterol and triglyceride, but WHR correlated significantly with cholesterol and triglyceride. In conclusion, these results from a present study support previous findings indicating that not only the degree of obesity but also the localization of fat is a risk factor for diabetes.

This paper provides a variety of viewpoints to illustrate the mechanism of the deck-stay interaction with the appropriate initial shapes of cable-stayed bridges. Based on the smooth and convergent bridge shapes obtained by the initial shape analysis, the one-element cable system (OECS) and multi-element cable system (MECS) models of the Kao Ping Hsi Bridge in Taiwan are developed to verify the applicability of the analytical model and numerical formulation from the field observations in the authors' previous work. For this purpose, the modal analysis of the two finite element models are conducted to calculate the natural frequency and normalized mode shape of the individual modes of the bridge. The modal coupling assessment is also performed to obtain the generalized mass ratios among the structural components for each mode of the bridge. The findings indicate that the coupled modes are attributed to the frequency loci veering and mode localization when the "pure" deck-tower frequency and the "pure" stay cable frequency approach one another, implying that the mode shapes of such coupled modes are simply different from those of the deck-tower system or stay cables alone. The distribution of the generalized mass ratios between the deck-tower system and stay cables are useful indices for quantitatively assessing the degree of coupling for each mode. These results are demonstrated to fully understand the mechanism of the deck-stay interaction with the appropriate initial shapes of cable-stayed bridges.

Using cross-ties to connect cables together when forming a cable network is regarded as an efficient method of mitigating cable vibrations. Cross-ties have been extended and fixed on bridge decks or towers in some engineering applications. However, the dynamics of this kind of system need to be further studied, and the effects of extending cross-links to bridge decks/towers on the modal response of the system should be assessed in detail. In this paper, a system of two cables connected by an inter-supported cross-link with another lower cross-link extended to the ground is proposed and analyzed. The characteristic equation of the system is derived, and some limiting solutions in closed form of the system are derived. Roots of cable system with special configurations are also discussed, attention being given to the case when the two cables are identical. A predictable mode behavior was found when the stiffness of inter-connection cross-link and the cross-link extended to the ground were the same. The vector of mode energy distribution and the degree of mode localization index are proposed so as to distinguish global and local modes. The change of mode behaviors is further discussed in the case when the two cables are not identical. Effects of cross-link stiffness, cross-link location, mass-tension ratio, cable length ratio and frequency ratio on $1^{st}$ mode frequency and mode shape are addressed.

This study does present things to suggest to foreign multinational corporation or domestic corporation through the empirical study on the standardization level. If we summary this study, it is as follows. In chapter I, we did institute the problems and explain the objects and methods and system of the study. In chapter II, we did explain the universality of the culture and international advertisement. Next, we did explain the background of doing specialization strategy and standardization strategy. Also we did study the previous study about the arguements for and against these. Lsat we did institute the hypothesises as follows. - Hypothesis 1 $H_0$ : The use of westerner appeal means has been increased than 11 years before and is able to increase continuously. - Hypothesis 2 $H_0$ : The use of westerner model and knowned has been increased than 11 years before and is able to increase continuously. - Hypothesis 3 $H_0$ : The use of the English language has been increased than 11 years before and is able to increase continuously. - Hypothesis 4 $H_0$ : The use of the west short piece and background has been increased than 11 years before and is able to increase continuously. In chapter III, we did refer to the method of this study. First, we did adjust the measure of standardization index, and we did work coding it, such after the two coder did check the freguency of the appeal meanstype about the advertisement of four daily report. Then we did select eight production as high involvement production and seven production as low involvement. We did test the coder's trust degree on the such sample to be selected through the 't-test' of the SAS statistic program and regression analysis through the spss/$pc^+$ statistic program to approve the this study's hypothesises. In chapter IV, we did analysis the results of the empirical study on the high or low involvement productions. First, the results of t-test to approve the coder's trust degree is that it is same statistically attentionly the distribution of the sample between coder at 10% attention level. Next, the results of the regression analysis on eight hypothesises are as fellows. In case of high involvement production we are able to speak that the use of the English language appeal among the eight appeals is only standardized. And incase of low involvement production, we are able to speak that the use of the hard-sell appeal among the eight appeds is only standardized. Therefore we did conclude that the standardization level of Korea newspaper advertisement is low. Also this suggests that it will do plan and do the specialzation strategy or localization strategy foreign multinational corporation or domestic corporation in Korea newspaper advertisement. In chapter V, we do present the boundary of this study and new study methods.

Purpose : Multileaf collimator(MLC) is very suitable tool for conformal radio-therapy and commissioning measurements for a multileaf collimator installed on a dual energy accelerator with 6 and 10MV photons are required, For modeling the collimator with treament planning software, detailed dosimetric characterization of the multileaf collimator including the penumbra width, leaf transmission between leaf leakage and localization of the leaf ends and sides is an essential requirement. materials and Methods : Measurement of characteristic data of the MLC with 26 pair block leaves installed on CLINAC 2100C linear accelerator was performed. Low sensitive radiographic film(X-omatV) was used for the penumbra measurement and separate experiments using radiographic film and thermoluminescent dosimeters were performed to verify the dose distribution, Measured films were analized with a photodensitometer of WP700i scanner. Results : For 6 & 10 MV x-ray energies, approximately $2.0\%$ of photons incident on the multileaf collimator were transmitted and an additional $0.5\%$ leakage occurs between the leaves. Localizing the physical end of the leaves showed less than 1mm deviation from the $50\%$ decrement line and this difference is attributed to the curved shaped end on the leaves One side of a sin히e leaf corresponded to the $50\%$ decrement line, but the opposite face was aligned with a lower value. This difference is due to the tongue and groove used to decrease between leaf leakage. Alignment of the leaves to form a straight edge resulted larger penumbra at far position from isocenter as compare with divergent alloy blocks. When the MLC edge is stepped by sloping field, the isodose lines follow the leaf pattern and Produce scalloping isodose curves in tissue. The effective penumbra by 45 degree stepped MLC is about 10mm at 10cm depth for 6MV x-ray. The difference of effective penumbra in deep tissue between MLC and divergent alloy blocks is small (5mm). Conclusion : Using the characteristic data of MLC, the MLC has the clinlical acceptability and suitability for 3-D conformal radiotherapy except small field size.
