A significant rise in product-liability cost is expected due to the newly passed product liability amendment Bill approved during the assembly plenary session on March 30, 2017. Korean government legal service(KGLS) filed a damage suit against Korea aerospace industries, Ltd.(KAI) and Hanwha Techwin Co., Ltd., the manufactures of the KUH-1 Surion helicopter crashed. KGLS alleged claims under the product liability Act, the warrant liability Act and the non-performance of contract act. The accountability limits of military aircraft manufacturers was a highly divisive issue among related scholars and legal practitioners. The bottom line was that military aircraft manufacturers had no product-liability insurance available. The United States courts have, therefore, developed the government contractor defense(GCD) and it was recognized by the U.S. Supreme Court in Boyle v. United Technologies corporation(1988). product liability insurances for military aircraft manufacturers are excessively expensive and it cannot be added onto the military procurement cost accounting. However, having an aircraft accident without one can be ruinously expensive. Therefore, the manufacturers should promptly set up appropriate risk management measures. This thesis will first review the advance GCD theory, and then find a way to either reform government contract related regulations.

It's not easy to renew old brand of over 50 years history to the tastes of new consumer of our time. Most of national brands that has a history of some 20 years in Korea have strove for continuation and growth of brand to no avails, which can be taken as a good example of current situation. For instance, C company, one of the National brand of US which has a history of 51 years, has made its position secure as a fashion group and based itself on a sound foundation by establishing new marketing strategy and completing successful brand renewal in the process of strategic M&A with Italian company. Those successful marketing strategies are as follows. 1) they regarded both market and consumer oriented marketing activity as company's highest priority strategy and put great emphasis upon concentration on target market and reestablishment of brand image of business casual wear. 2) Setting up and operating planning team composed of merchandizer alone in Milano, they set the direction of plan on the basis of concentrated research on potential item in market according to thorough market research done by buying office in Korea, branch office in Hong Kong and buyer in US prior to blueprint planning for season. 3) Great emphasis was placed on business which focused on intensive presentation of basic key item for apparel career women who are main consumer group in the midium-low prices market in US and on supplementation of size and color. they named this line 'collectibles' and helped their customer develop their own clothes plan without worrying about the change of color and fabric by supporting same fabric and color throughout the year and enabled them to add variation easily by supplementing new trend item. 4) Company set black as a main color that lots of apparel career women find easy to care and to express their own image and presented them with pebble which belongs to navy and beige and added fashion color such as wine and brown etc as season goes by. They constructed basic line in order for their customers to coordinate purchased item with new one or to add them to present collection, and to achieve efficient sale by setting up strategy which allows this cross coordination and changing pattern occasionally. 5) Though basic jacket for 99$, short slim skirt for 49$ are products within midium-low prices range, in the material planning stage aiming at production of item that has both resonable function appealing to consumer and is fashionable, synthetic material had to be used as a main source due to price competitiveness. Despite this situation, considering comfortable sense of fit and refined drape of silhouette that has no sign of cheap material, whole collectible line was divided into two items, which contributed to reduction of cost. In case of material that is composed of triacetate and polyester in 70 to 30 ratio, was used up to 4 million yard, which allowed drastic curtailment of cost accompanied by concentration. In case of 'collectibles' line, using Korean material mainly, C company chose to have their product sewed in Southeast Asian countries where transportation is well developed and both productivity and quality verified by operating global production system which aiming at cutdown of cost through outsourcing production from the country where labor cost is low and getting finished product. Polarization between present consumers telling us that consumers with the mind of middle classes in the past no longer exists between consumers who seek after only fine article of highest quality and wise consumers who are sensible enough to judge bubble on correlation between price and quality. To cope with this change in new consumer mind, apparel makes changing their policy so as to produce item that has reasonable quality and falls within affordable price range anywhere in the world. and they're striving to get out of difficult situation by operating global marketing strategy which stresses separation of planning, production and sale and sensibility of fashion shared worldwide. The marketing strategy of C company can be exemplified as a successful one.

Injection molding is a method for manufacturing many products, wherein a plasticized resin is injected into a mold at high pressure and hardened. According to the method, the product can be manufactured into various forms, and the mass production of up to tens of thousands of products is possible. The purpose of this study was to determine the process conditions for manufacturing a door latch for automobiles, through an analysis of the injection molding method. To calculate an appropriate injection flow for injection molding, a primary analysis for comparing the injection time, pressure, flow pattern, consolidation range, shear stress, shear rate, and weld line, as well as a secondary analysis for determining the conditions for stabilizing the molding temperature, holding pressure, and cooling process, were conducted. The characteristics of injection molding, and their influence on the product quality are discussed. No weld line and pores were observed on the products that had been manufactured based on the process conditions determined above. In addition, there were no flaws regarding the deformation compared to the prototype. Therefore, the manufacture of a product under the conditions determined in this study can reduce the defect rate compared to the existing production, and the process is also more competitive due to reduced production time.

TQM is a whole process of systemizing, documenting and measuring of service quality scientifically to achieve zero defects in product quality and to continue to improve the body of the product quality by itself. To have this process be improved continuously, first of all it needs to prepare an ideal environment to understand and to conform to its internal and external customers', that is every guests' and employees' expectations and demands. Then it has to be followed by the next step removing some negative aspects that could be derived from the first mentioned process The third step is to cut the cost be suitable compensation rather than an attitude trying to solve the problems in an easy way. The last essential factor for setting up TQM system is to make good use of the outstanding feature or process as it is reviewed against the superior benchmark. The purpose of this study is meet the customers' expectations and to maximize the hotel's profits by searching TQM(total quality management) strategy in hotels. To attain this research's objective, it follows these three details. Firstly, it defines TQM and its contents. Secondly, it provides the standard of hotel TQM throughout some case studies. Thirdly, it suggests TQM strategic plan in tourism hotel as one of professional management strategies. Two useful methods are used together to achieve the goal of this study. To confirm its theoretical consideration, descriptive studies by the research documents its theoretical consideration, descriptive studies by the research documents published in and out of the country is used. The other is case studies of TQM execution in real hospitality industry, which present the cases of the airline, Jefferson Memorial and the hotel. This research is targeting to demonstrate the successful TQM's exercise in a hotel industry by completing the theoretical studies and case studies on service product quality with an understanding of its importance. As it is said earlier, to lead to the successful TQM's practice, it is necessary to maintain a constant training of the employees. Secondly, it also must identify where it has to focus on to deliver a professional quality management. Thirdly, effective quality management organization needs to be build up. The manager's strong will to accomplish and the employee' active participations are the last condition to be succeed. Once again this study places an emphasis on the fact that TQM is critical to maximize the customers' satisfaction and the hotel's profitability. It is also very worthwhile to have every people working on front line recognize why the TQM is important and further more how they can contribute to improve their service quality by a positive participation and a careful observation of TQM's operating in their property.

The purpose of this study is to investigate the effect of product selection of hospital workers cosmeceutical cosmetics on marketing communication among hospital workers who use cosmeceutical cosmetics that have emerged in line with the recent growing medical skin care field.Coping with complaints from consumers who buy cosmeceutical cosmetics in hospitals where cosmeceutical cosmetics are mainly used and sold, and minimizing the influence of negative issues will potentially strengthen consumer relationships. The study was conducted on 520 hospital workers who use cosmeceutical cosmetics in hospitals (dermatology, plastic surgery, women's clinic, and other hospitals) in Seoul, Gyeonggi and Incheon. A total of 502 questionnaires were used for the final analysis. The data analysis consisted of Cronbach's alpha, one-way ANOVA, exploratory factor analysis and Duncan test. Correlation analysis was performed to investigate the correlation between variables, and regression analysis was conducted to test hypotheses. The study results revealed that when choosing cosmetic cosmetics, marketing communication is influential. Especially, product value, quality, and price factors strongly affect marketing communication. This shows that we value the product and quality the most and we want a reasonable price. Considering this, we will pursue differentiated products only from cosmeceutical cosmetics and provide them as basic data necessary for securing potential customers and increasing the sales of cosmeceutical cosmetics in accordance with the changing trends.

The design of best efficient production process is common requirements of the production strategy department and the process planning department to maximize the revenue and accomplish target production volumes in the production periods. And they use several general methods for that-line-balancing, removing of the bottle-neck process, facility ramp-up, increasing of the worker's utilization, etc. But, those methods have depended on analytic, static and arithmetic calculations, yet. So, irregular work-waiting time causing the delay time isn't include in extracting production capacity, especially in the line production process. The work-waiting time is changed irregularly along the variation of each machine and very important for calculate real product lead-time and forecasting target production volumes. At this thesis, i'm going to mention the importance of the delay time of conveyor system which can be extracted by discrete-event simulation. And suggest it as a new main variable that must be considered at designing new production system. Then experimented and tested that's effects in the H-company case, conveyor based line production process.

Korean export of fashion products to the U.S. has fallen off sharply after 2001. Now, Korean fashion companies have to develop higher value-added business. In the U.S., Korean-American fashion companies are taking a primary role in up-stream of the fashion industry. To cut the edge over the U.S. fashion companies, one of the solutions could be to build the business relationship with Korean fashion companies which reflect the recent trend rapidly and have high quality production. On this study, we investigated the marketing strategies of Korean-American fashion companies to seek to start business with Korean fashion companies and make suggestions for Korean fashion companies who want to enter into the U.S. market effectively. To analyze current situation of Korean export to the U.S. and the U.S. fashion industry, we considered various kinds of statistic data, publications and studies. And we performed in-depth interviews with 9 Korean-American fashion companies in LA from $9^{th}$ to $21^{st}$ of July. The results are as follows. first, Korean fashion companies should aim for high-end market with the products of high quality and design. Second, there should be professional agents who manage Korean small-medium fashion companies and connect them with Korean-American fashion companies. Third, Korean fashion companies who want to enter into the retail market of the U.S. have to decide the target market clearly and plan strategic and differentiated merchandising. Fourth, Korean fashion companies can specialize in product developing service like proposing a product or a merchandising line as a package including designs, fabric swatches, trims, production information, etc.

Background The Exoscope is a novel high-definition digital camera system. There is limited evidence signifying the use of exoscopic devices in microsurgery. This trial objectively assesses the effects of the use of the Exoscope as an alternative to the standard operating microscope (OM) on the performance of experts in a simulated microvascular anastomosis. Methods Modus V Exoscope and OM were used by expert microsurgeons to perform standardized tasks. Hand-motion analyzer measured the total pathlength (TP), total movements (TM), total time (TT), and quality of end-product anastomosis. A clinical margin of TT was performed to prove non-inferiority. An expert performed consecutive microvascular anastomoses to provide the exoscopic learning curve until reached plateau in TT. Results Ten micro sutures and 10 anastomoses were performed. Analysis demonstrated statistically significant differences in performing micro sutures for TP, TM, and TT. There was statistical significance in TM and TT, however, marginal non-significant difference in TP regarding microvascular anastomoses performance. The intimal suture line analysis demonstrated no statistically significant differences. Non-inferiority results based on clinical inferiority margin (Δ) of TT=10 minutes demonstrated an absolute difference of 0.07 minutes between OM and Exoscope cohorts. A 51%, 58%, and 46% improvement or reduction was achieved in TT, TM, TP, respectively, during the exoscopic microvascular anastomosis learning curve. Conclusions This study demonstrated that experts' Exoscope anastomoses appear non-inferior to the OM anastomoses. Exoscopic microvascular anastomosis was more time consuming but end-product (patency) in not clinically inferior. Experts' "warm-up" learning curve is steep but swift and may prove to reach clinical equality.

Objective: The objectives of this study were to determine the in situ degradation parameters and appropriate feeding level of pineapple cannery by-products (PCB) based on the growth performance and blood parameters of growing Hanwoo (Bos taurus coreanae) steers fed various levels of PCB. Methods: Two ruminally cannulated Holstein cows were used for in situ disappearance rate measurements. Nylon bags (5×10 cm, 45 ㎛ pore size) filled with 5 g of PCB in triplicate were inserted into the ventral sac of the two cannulated Holsteins cows and incubated for 0, 2, 4, 8, 16, 24, and 48 h. A total of 16 castrated growing Hanwoo steers (12.5±0.5 months old, 302.9±25.7 kg of initial body weight [BW]) were used for the experiment. Animals were stratified by initial BW and then randomly assigned to one of four experimental diets (0%, 1.5%, 3.0%, or 6.0% of PCB, on the dry matter [DM] basis) fed for 91-d, including 30-d of adaptation. Results: Soluble fraction a of DM and crude protein (CP) was 61.9% and 86.0%, fraction b of DM and CP was 32.7% and 11.2%, and indigestible fraction c of DM and CP was 5.4% and 2.8%. The 6.0% PCB feeding group showed lower productivity compared to animals in the other treatments. Increasing the dietary level of PCB did not alter DM intake, but it was numerically lowest in the 6.0% feeding group. The gain to feed ratio was linearly decreased by increasing of PCB. The quadratic broken-line test estimated that 2.5% (DM basis) was the maximum feeding level of PCB in growing Hanwoo steers (y = 0.103 - 0.001×[1.245-x]2, R2 = 0.18). Conclusion: Diets containing up to 2.5% PCB can be fed to growing Hanwoo steers without adverse effects on growth performance.
