This paper presents a new web cluster scheme based on dispatcher which does not depend on operating system for server and can examine server's status interactively. Two principal functions are proposed for new web cluster technique. The one is self-controlled load distribution and the other is transaction fail-safe. Self-controlled load distribution function checks response time and status of servers periodically, then it decides where the traffic goes to guarantee rapid response for every query. Transaction fail-safe function can recover lost queries including broken transaction immediately from server errors. Proposed new web cluster scheme is implemented by C language on Unix operating system and compared with legacy web cluster products. On the comparison with broadcast based web cluster, proposed new web cluster results higher performance as more traffic comes. And on the comparison with a round-robin DNS based web cluster, it results similar performance at the case of traffic processing. But when the situation of one server crashed, proposed web cluster processed traffics more reliably without lost queries. So, new web cluster scheme Proposed on this dissertation can give alternative plan about highly increasing traffics and server load due to heavy traffics to build more reliable and utilized services.

This study aimed to provide basic data for the design and R&D of golf wear intended for 64 people in their 40s, 50s, and 60s by identifying the needs for golfers through a survey of golf wear purchasing conditions and preferences. The findings shows that purchases are made at permanent discount stores, and information about products are discovered through TV and Internet advertisements. Golf wear is purchased once or twice a year, with annual expenditures ranging from KRW 500,000 to less than 1 million, with single purchases ranging from KRW 200,000 to less than 500,000. When purchasing golf wear, design was considered first, with women preferring white garment, while men preferred black and gray ones. Men tended to prefer a PK collar button fastening style, while women preferred a knit style with a round neckline. Women preferred semi-fitted and fitted styles, while men preferred semi-fitted and loose-fitting styles, showing significant differences. When considering the production of golf wear, the younger the age of the consumer, the more the results indicated that the design needed to look younger, so it is the necessary to design golf wear that reflects the functional need of golfer while prioritizing designs for various ages.
