The study proved the fitness between competitive strategy and service operation strategy of service companies. The competitive strategy of a corporation is a major strategy playing the role of bridge linking both corporate strategy and functional strategy. And it is a choice of method how to win competitors in given area. There have been such a specific methodologies for acquiring competitive advantage as Porters competitive strategy, Miles and Snows adaptive strategy, and Life cycle strategy. But, many scholars have pointed that its more important for high corporate performance to determine the competitive strategy of a corporation fitting the external environment and internal structure. So its needed for successful cost-leadership or differentiation strategy to differentiate organizational function, resources, and various organizational factors. But there have been no methodologies or practical guidelines fitting competitive strategy, corporate structure, and external environment in sprite do service corporations growth. So, the study proved the fitness between competitive strategy and service operation structure in Airlines after selecting service structural elements necessary for strategic management.

This paper presents a method evaluating benefits of ramp metering strategies on freeway safety. Based on the traffic and the accident data collected on a 4.2 km (2.6 mile) section of Interstate highway 35-West in Minneapolis, U.S.A., the relationship between traffic variables and safety measures is investigated. An aggregate specification that could be used to predict accident frequencies on freeways is proposed as a multiple regression form. The specification includes 15 minutes volume and occupancy data, which are commonly available from surveillance and control systems. The primary variables that appear to affect the frequencies of freeway accident are: vehicle-miles of travel, entrance ramp volumes and the dynamic effect of queue building. A simulation method evaluating the dynamic effect of control strategies on safety is proposed next. The potential benefits of freeway ramp metering on freeway safety are finally investigated via a proposed method.

재즈의 가장 중심적 인물인 마일즈 데이비스의 'Bitches Brew'는 일반적으로 70년대 이후 현대 음악의 뿌리로 언급된다. 즉, �� 음악과 재즈가 합쳐진 퓨전음악이 시작으로 보는 것인데, 이 연구에서는 단지 시대적 흐름에 따라 형성된 악기 편성과 연주 방식에 프리재즈의 영향이 더해지면서 탄생한 것으로 본다. 수많은 예술적 표현 가운데 새로움에 대한 갈망과 형식에 대한 반감은 문학에서도 포스트-모더니즘적 작품들로 나타나게 되는데, 그 표현 방식에서의 주제의식이 마일즈 데이비스의 'Bitches Brew'의 그것과 상당히 흡사하다. 존 바스의 주제의식과 마일즈 데이비스의 기존의 양식을 다르게 보는 시각을 비교, 분석하여 재즈의 포스트모더니즘을 유추하여 본다.

This study investigated the adaptation process of abused children in long-term foster care and the stages of adaptation process. Also, this study aimed to find the factors influencing the adaptation of abused children in long-term foster care and to examine the relationships between the adaptation process in long-term foster care and the recovery of aftereffect of the abused children. The researchers tried to find the factors influencing the possibilities about the return of their biological parents' home. The researchers used a purposeful sampling and interviewed three abused children and three parents in long-term foster care and two social workers. This study utilized grounded theory approach of Strauss and Corbin(1990) to analyze the interviewed data. Specifically, the researchers applied open coding, axial coding and selective coding from grounded theory approach to analyze the data. On the other hand, the researchers used Miles and Huberman(1994)'s time-ordered matrix and time-ordered network to investigate the categories influencing the adaptation process of abused children in long-term foster care. This study used interviewees, literatures, newspapers, and internet resources relating to abused children for triangulation of data. The researcher interviewed from October 15, 2004 to January 31, 2005. The total sessions of each person were consisted of two sessions for each person and the interview time of each session was one or two hours.

Solvent-free low foaming scouring agents(LFSA) were prepared by blending of polyoxyethylene(30) octadecylbenzylammonium chloride(POAC), block copolymer of propylene oxide-ethylene oxide[p(PO-b-EO) glycol], Sedlan FF-200(FF-200) and sulfonic acid-amine condensate of polyoxyethylene(10) nonylphenyl ether(PSAC). In consequence of several tests, FF-200/POAC/p(PO-b-EO) glycol/PSAC/water (20g/10g/5g/5g/60g) mixture (LFSA-5) showed good cleaning power, penetrating ability, emulsifiability and stability to alkali, and gave less problem in water pollution. Scouring effect of LFSA-5 was investigated by the change of percentage of exhaustion before and after scouring at various dyeing temperatures. The percentage of exhaustion of the unscoured PET fabric was 4.5% at $70^{\circ}C$, while that scoured with LFSA-5 was 1.3% at the same temperature, which proved LFSA-5 to be a good scouring agent. Moreover, the foaming power of LFSA-5 measured by Ross and Miles method was 6mm foam height immediately after foaming, and that measured by Ross and Clark method was less than 300mm foam height at $30^{\circ}C$, and 20mm at $80^{\circ}C$. As a result, LFSA-5 proved a good low foaming scouring agent.

This study analyzed military personnel survivability in regards to offensive operations according to the scientific military training data of a reinforced infantry battalion. Scientific battle training was conducted at the Korea Combat Training Center (KCTC) training facility and utilized scientific military training equipment that included MILES and the main exercise control system. The training audience freely engaged an OPFOR who is an expert at tactics and weapon systems. It provides a statistical analysis of data in regards to state-of-the-art military training because the scientific battle training system saves and utilizes all training zone data for analysis and after action review as well as offers training control during the training period. The methodologies used the Cox PH modeling (which does not require parametric distribution assumptions) and decision tree modeling for survival data such as CART, GUIDE, and CTREE for richer and easier interpretation. The variables that violate the PH assumption were stratified and analyzed. Since the Cox PH model result was not easy to interpret the period of service, additional interpretation was attempted through univariate local regression. CART, GUIDE, and CTREE formed different tree models which allow for various interpretations.
