Classical SPC charting methods such as (equation omitted), R, S charts assume high volume manufacturing processes where at least 25 or 30 calibrate samples of size 4 or 5 each can be gathered to estimate the process parameters before on-line charting actually begines. However, for many processes, especially in a job-shop setting, production runs are not necessarily long and charting technique are required that do not that depend upon knowing the process parameters in advance of the run. In this paper, using modifying statistics, we give a method for constructing control charts for the process mean when the measurements are from a normal distribution. In this case, consider that smaller weight being assigned to the older data as time process and properties and taking method of exponential smoothing constant$(\lambda)$ are suggested.

Particle Swarm Optimization (PSO) which has been well known to solve continuous problems can be applied to discrete combinatorial problems. Several DPSO (Discrete Particle Swarm Optimization) algorithms have been proposed to solve discrete problems such as traveling salesman, vehicle routing, and flow shop scheduling problems. They are different in representation of position and velocity vectors, operation mechanisms for updating vectors. In this paper, the performance of 5 DPSOs is analyzed by applying to traditional Traveling Salesman Problems. The experiment shows that DPSOs are comparable or superior to a genetic algorithm (GA). Also, hybrid PSO combined with local optimization (i.e., 2-OPT) provides much improved solutions. Since DPSO requires more computation time compared with GA, however, the performance of hybrid DPSO is not better than hybrid GA.

For producing large numbers of professional nurses who could manage 21th century's human health, it is necessary to review the direction of registered nurses' national examination which evaluates the nursing education and is granted a licence. For adapting to social expectation of the nurse, we have to nurture the nurses' problem solving capability in clinical setting. Seven divisions of Korean Academy of Nursing suggested clinical competency according to their categories. This paper was presented in the work-shop for setting up direction of registered nurses' national examination. We expect that this paper would be more refine and confirm through reviewing subdivisions' learning objectives and discussing clinical minimum level of competence contents with clinical leaders.

This study investigates the buying behavior of apparel by middle aged women according to lifestyles. Questionnaires were distributed to 300 women who lived in the Seoul area and between 40 to 65 years of age. A sample of 248 women responded. To analyze the data, Factor Analysis, Cluster Analysis, Analysis of Variance (ANOVA) and a Duncan test were used. As a result, the respondents were clustered into 4 different groups according to lifestyles. The groups included practical oriented group, economic oriented and practical group, active oriented and appearance group, and economic group. Their buying behavior was as follows. First, the active oriented and appearance group shopped at department stores and specialty stores; however, the economic oriented and practical group shopped at discount stores more often than other groups. The practical group shopped more frequently using TV home shopping networks, discount stores, and outlet stores, the economic group shopped at off-price stores, discount stores, and online more than the other groups. Second, the active oriented and appearance group bought classic suits and semi-classic suits, imported brand and/or designer brand apparel more often than other groups. Third, the active oriented and appearance group perceived another person's appearance, advertisement, and shop display as a more important information source than other groups. Forth, the active oriented and appearance group considered design & style, harmony with self-image, brand name, color, and coordination with other clothing as more important selection factors for clothing than other groups. The economic groups considered coordination with other clothing; however, the economic oriented and practical group cited ease of care as more important factors.

With the goal of searching for the ways to help market traditional beverages as take-out products, this study conducted a survey over men and women over 20 years of age in Seoul and Gyeonggi Province. Their perceptions of importance in choosing traditional beverages and conventional drinks were examined for difference. As a result, taste, reliability, health, flavor, and price were important at general beverage, while taste, health, flavor, reliability, price, and color were in choosing traditional beverages. The participants mentioned recovery from fatigue as the most favorable added feature of traditional beverages, which was followed by beneficial for adult diseases and facilitating digestion. Their preferences toward using them to satisfying a sense of hunger was relatively low. The participants preferred price range was $3,000{\sim}3,500$ won, their favorite ingredients were functional ones, and their favorite shop design was a traditional style. It seems that the marketability of traditional beverages as take-out products is high. The promotion and development efforts should involve marketing to women, differentiation strategies from other drinks, a graceful image, reliable drinks, and additional functions such as recovery from fatigue and can benefit adult diseases.
