This paper presents a framework for the hierarchical PPC(Production Planning and Control) in make-to-order environment with job shop. The characteristics of the environment are described as : 1) project with non-repetitive and individual production, 2) short delivery date, 3) process layout with large scales manufacturing. 4) job shops. The PPC in a make-to-order typically are organized along hierarchical fashions. A model is proposed for the hierarchical job shop scheduling based on new concepts of production system, work and worker organization. Then, a new integrated hierarchical framework is also developed for the PPC based on concepts of the proposed job shops scheduling model. Finally, the proposed framework has been implemented in the Electric Motor Manufacturing and the results showed good performance.

Self-leadership means a person's ability to make his thought or behavior in a right way by controlling it himself. Strategies of the same leadership can be largely categorized into three, behavior focused, natural reward and constructive thought strategies. In this study, the foresaid styles of self-leadership strategy are discussed from the perspective of dental lab laboratories' business environment of Gyeongnam region. And accordingly, this researcher examined such strategy styles that dental lab managers, chief technicians and assistant technicians usually have. Results of the study can be summarized as follows. First, out of the self-leadership strategy styles, most remarkably found among the professional of dental technology was constructive thought strategy, followed by behavior-focused and natural reward strategies in order. In general, therefore, the professionals strongly tend to make their thoughts that can a positive effect on their work performance or in a constructive way. In other words, professional dental technicians are more likely to make efforts to persuade or persuade themselves to change their own unreasonable confidence or negative process in more positive way. Second, the extent to which constructive thought strategy is perceived was not different among dental lab managers, chief technicians and assistant technicians. While, behavior-focused and natural reward strategies were found most strongly perceived by dental lab managers, followed by chief and assistant technicians in order. This may be attributed to the fact that the higher professional dental technicians are in position, the higher they are in self-leadership, or in the ability to overcome crises by themselves and make their thought or behavior in a right way. Dental lab managers usually have lots of experiences in relation to behavior-focused or natural reward strategy. Therefore, they are very strongly capable of controlling themselves in order to overcome crises or make their thought or behavior in a right way. In contrast, assistant technicians are still having lots of trials and errors because they are less experienced and skilled. This suggests that chief technicians should make themselves fully capable as a medium that connects between dental lab managers and assistant technicians.

Many of legislations related to tourism has been made up to now since the year 1961 when modern tourism studies started. In restropect of the year 1988, the year 2002 is expected to be another chance for tourism. In order to take this chance again, new laws and regulations are necessary. Therefore, the object of this study are decided as follows: 1) to put 'the right to go sightseeing' in statutory form at constitution. 2) to realise the private law of tourism 3) to make the environment law of tourism 4) to make the facility law of tourism 5) to make the transportation law of tourism 6) to make the cultural property law of tourism 7) to make the food law of tourism 8) to make the related law of tourism 9) to make the advertising law of tourism, the tax law of tourism, and the economy law of tourism As tourism laws like above exist, tourism industry would be developed more than now.

This study presents a web log analysis model for e-CRM, which combines the on-line customer's purchasing pattern data and transaction data between companies in B2B environment of make-to-order company. With this study, the customer evaluation and the customer subdivision are available. We can forecast the estimate demands with periodical products sales records. Also, the purchasing rate per each product, the purchasing intention rate, and the purchasing rate per companies can be used as the basic data for the strategy for receiving the orders in future. These measures are used to evaluate the business strategy, the quality ability on products, the customer's demands, the benefits of customer and the customer's loyalty. And it is used to evaluate the customer's purchasing patterns, the response analysis, the customer's secession rate, the earning rate, and the customer's needs. With this, we can satisfy various customers' demands, therefore, we can multiply the company's benefits. And we presents case of the 'H' company, which has the make-to-order manufacture environment, in order to verify the effect of the proposal system.

Classification and Coding(C&C) systems as a core of design information management have been accomplished by many studies in terms of design and manufacturing attribute based on Group Technology. Those are very difficult to apply in make-to-order(MTO) manufacturing because the environment of MTO has various characteristics of product, many licensors, engineering change, insufficiency of integrated management system for codes and so on. This paper presents a suitable C&C system to MTO manufacturing which consider management level and drawing.

The purpose of this study is understanding female high school student's make-up culture by developing the recognition criteria for their make-up behavior and anxiety in purchasing cosmetics. This study targeted 524 female high school students who attended vocational and academic high school located in Daegu, Korea. SPSS WIN package was used fur statistics and MANOVA, ANOVA, LSD post-verification was conducted for data analysis. The conclusion of this study is as fellowed ; (1) Academic groups showed statistically different tendency to 6 reasons of make-up behavior ; interest in make-up was chosen most for the reason and etiquette, make-up satisfaction, aesthetics, fashion, synchronism comes next in the order. (2) In case of vocational group, it also showed different tendency to 6 reasons of make-up behavior ; interest in make-up was also most highly chosen reason as the academic group and etiquette was next and then make-up satisfaction, aesthetics, fashion were same level and synchronism was shown to be the lowest chosen reason in the order. (3) Academic group showed different level of anxiety from the 11 reasons of anxiety in purchasing cosmetics ; also anxiety of material was highly chosen reason and then fitness, price, color, quality, utility, purchasing, after service, fashion, label-trust, other people's comments comes next for the reason. (4) Vocational group also showed different level of anxiety from 11 reasons of anxiety in purchasing cosmetics; also anxiety of material was highest reason (same as the academic group) and then fitness, color, quality, price, utility, after service, label-trust, fashion, buying, other people's comments comes next for the reason.

The women selected by random sampling were classified into four groups by their body cathexis and Make-up attitude in order to investigate differences in Clothing Value and Make-up behavior. The result are as follows. Cluster was classified into four groups: positive congruity(G1), positive incongruity(G2), negative congruity(G3), negative incongruity(G4). Four groups showed meaningful difference each other between the peculiarity of Clothing value and Make-up behavior. Make-up behaviors were different at the peculiarity of minutely divided groups under the standard of physical satisfaction and Make-up attitude, and they showed difference in the influence of value affected to each behavior. So it was testified that Make-up behavior can be different depending on the value of respective persons.

In this study we develop a computer simulation model to evaluate the effects of various production and order processing policies measured in terms of on-time delivery rate and average waiting time of job orders. Policies considered include : eliminating inflated due date, lot splitting, loss time reduction, attaining full flexibility in production lines, and selective order promising scheme. Actual order-production data from a chemical company were used in the simulation model. Based on the simulation results, we make several suggestions that can significantly reduce the production lead time and increase the on-time delivery rate.
