The purpose of this paper is to extend the idea of Tamhane and Bechhofer (1977, 1979) concerning the normal means problem to some general class of distributions. The key idea in Tamhane and Bechhofer is the derivation of the computable lower bounds on the probability of a correct selection. To derive such lower bounds, they used the specific covariance structure of a multivariate normal distribution. It is shown that such lower bounds can be obtained for a class of stochastically increasing distributions under certain conditions, which is sufficiently general so as to include the normal means problem as a special application. As an application of the general theory to the scale parameters problem, a two-stage elimination type procedure for selecting the population associated with the smallest variance from among several normal populations is proposed. The design constants are tabulated and the relative efficiencies are computed.

It is difficult to understand the interior of complex facilities such as general hospital. Because interior spatial composition in hospital tends to be focused on function. So it is important to find out how people understands the structure of interior spaces. Therefore, this study aims to analyze how interior space affects the legibility of space making use of puzzle map method. The subjects of this investigation are two general hospitals which have typical plans in Korea. ; One is corridor type and the other is hall type.

It's difficult to understand the interior of complex facilities such as general hospital, because interior spatial composition in hospital tends to be focused. So it is important to find out how people understand the structure of interior spaces. Therefore, this study aims to analyze spatial information from the sign data concerned with sighting and thinking of subject who make way-finding as a first-time visit from an entrance to a goal by way-finding method and clarify plan of sign in two general hospital which have typical plans in Korea.; One is corridor type and the other is hall type.

We introduce the notion of Gauss map of pointwise 1-type on ruled surfaces in the Euclidean 3-space for which vector valued functions is neither trivial nor it extends or coincides with the usual notion of 1-type, in general. We characterize the minimal helicoid in terms of it and give a complete classification of the ruled surfaces with pointwise 1-type Gauss map.

Purpose: This study aims to explore general perception types about the life of institutionalized elderly and thus to provide the basic data for nursing intervention for them. Method: This study used a Q methodology. A Q sample was developed through a review of related literature and descriptions of ordinary people about the life of institutionalized elderly. Thirty-eight statements made up the finalized Q sample. Results: The results revealed three different types of the general people's perception about the life of institutionalized elderly. Type 1 is an optimistic group which expects modernized institutions. This group focuses on social relationships enjoying a variety of cultural life. Type 2 is a positive group which pursues independence. They are open-minded about the use of the institution and are not ashamed of the life in the institution. Type 3 is a conservative group which disapproves institutionalization. The members of this group strongly disapprove the institution itself and have negative views on institutionalization. These three types share certain common features while having distinctive characteristics showing individual views and traits about the life of the institutionalized elderly. Conclusion: This study will provide us the basic data to understand institutionalized elderly and to develop nursing intervention for them.

Various types of electronic starter have been developed for the general fluorescent lamps with magnetic-type ballasts. However, the FL032/T8 fluorescent lamp requires higher voltage to discharge the lamp. The general starter with two-terminal is not suitable for the FL032/T8 slim-line type fluorescent for its higher discharge voltage. The suitable starter with three terminals have been studied for the FL032/T8 lamp in this paper. The developed starter have better characteristics in view points of the discharge voltage magnitude. We have proposed and designed the three terminals electronic starter. The proposed starter have been experimented and compaired with the other 2-terminal general starters. By the experimental results, we have concluded that the proposed starter is suitable to the FL032/T8 lamp.

The cytologic detection of endometrial carcinoma in Papanicolaou(Pap) smear according to histologic type, grade and stage was studied in 49 patients. The smears of patients who had histologically confirmed were retrospectively evaluated by the Bethesda System. The cytologic diagnosis of endometrial carcinoma was made in 61% (39/49) of patients, atypical glandular cells of undetermined significance (AGCUS) in 16% (8/49) and within normal limits in 23% (11/49). The positive rate for AGCUS and carcinoma was correlated to the histologic type, grade and stage. The cytologic grade revealed a good correlation with histologic grade, too. In conclusion, the presence of cancer cells in Pap smear suggests the tumor in high grade and high stage. Additionally, cytologic detection of AGCUS or carcinoma needs a further diagnostic evaluation. The Pap smear is a valuable method to screen for endometrial carcinoma.

The purposes of this paper are to revise the definitions of Ishikawa and Mann type iterative processes with errors, to study the unique solution of the m-accretive operator equation x+Tx=f and the convergence problem of Ishikawa and Mann type iterative processes with errors for m-accretive mappings without the Lipschitz condition. The results presented in this paper improve, extend, and unify the corresponding results in [4, 7, 8, 12, 16] in more general setting.

Background: It is well known that the distribution of therapeutic materials is very complex. However, it is not easy to demonstrate the concrete problems caused by distribution channels empirically. The purpose of this study was to investigate the differences in the price of therapeutic materials according to the type of purchasing agency and the way in which medical institutions purchase therapeutic materials. Methods: This study compared the claimed prices and the maximum allowable prices for the items of therapeutic material used for general spinal surgery. Results: Ilsan Hospital, which purchased directly without a purchasing agent, had the lowest claimed prices, followed by a large professional purchasing agency, a foundation-related purchasing agency, and a general purchasing agency. In addition, the difference between the claimed prices and the maximum allowable prices according to the purchase type was larger in the expensive treatment materials, and in the case of the lower price treatment materials, it tended to converge to the maximum allowable prices. Conclusion: National health insurance spending for therapeutic materials are to be affected by the distribution channels of them. We proposed several ideas to rationalize the expenditure such as classification of therapeutic materials on the basis of price or other criteria.

The aim of this study was to investigate whether there are differences in mother's parenting behaviors and children's playfulness and communication abilities according to the type of family and to determine the relationships among these variables. A total of 154 pairs consisting of 77 pairs of children and their mothers from multi-cultural families and 77 pairs of children and mothers from general families along with 76 teachers in charge of the children participated in this study. We found that there was a difference in the children's playfulness and communication ability according to the family type. Moreover, the relationship between the mothers' parenting behaviors and their children's playfulness and communication ability levels differed according to family type. Therefore, to understand children's playfulness and communication ability in general and multicultural families, it is necessary to consider each child's environment.
