Recently many small and mid-sized hospitals are closing down or experiencing financial difficulties. As a result, in order to provide exceptional service that would increase their competitiveness, they implemented telemedicine service for the prescription of medicine necessary before a colonoscopy. This study is an analysis of how telemedicine service affects patient satisfaction. Through the focus group interview (FGI) of medical service providers, regarding telemedicine service and face-to-face service, it was appraised that telemedicine service was more effective than face-to-face service. Afterward, a second survey aimed at endoscopy patients was conducted in order to find out the value of telemedicine service. First, through the analysis of the three main factors of telemedicine service, conclusions were drawn(safety/reliability, convenience/rapidity, and economics). A follow-up analysis showed that convenience/rapidity had the greatest effect on telemedicine service satisfaction. Next the factors of the quality of medical service were analyzed and 3 main factors were deduced (the superiority of the external and internal environments/appropriateness, superiority of the medical team, telemedicine service). A follow-up analysis found that telemedicine service had the greatest effect on patient satisfaction. This study found that providing exceptional medical service that utilizes telemedicine service would improve patient satisfaction. Therefore, we would be able to form a strategic plan that would strengthen the competitiveness of small and mid-sized hospitals.

A method for forming production cells in cellular manufacturing systems is presented. The basic approach is based on part-machine group formation by using relationship matrix calculated from the original part-machine matrix. The cases of exceptional elements and bottleneck machines are discussed. The proposed method can work with any starting form of part-machine matrix and provides the same solution regardless of the changes of starting form of part-machine matrix for any given problem.

Let L := L(G) denote the classical modular Lie algebra of $E_6$-type over an algebraically closed field F of characteristic p > 5 associated with some simple and simply connected algebraic group G. After the prototypes of those for $E_8$-type in [4], we shall search for irreducible (=simple) L-modules in this paper.

The spherical buildings associated with absolutely simple algebraic groups of relative rank 2 are all Moufang polygons. Tits polygons are a more general class of geometric structures that includes Moufang polygons as a special case. Dagger-sharp Tits n-gons exist only for n = 3, 4, 6 and 8. Moufang octagons were classified by Tits. We show here that there are no dagger-sharp Tits octagons that are not Moufang. As part of the proof it is shown that the same conclusion holds for a certain class of dagger-sharp Tits quadrangles.

The machine cell formation problem is the problem to group machines into machine families and parts into part families so as to minimize bottleneck machines, exceptional parts, and inter-cell part movements in cellular manufacturing systems and flexible manufacturing systems. This paper proposes a new machine cell formation method based on the adaptive Hamming net which is a kind of neural network model. To show the applicability of the proposed method, it presents some experiment results and compares the method with other cell formation methods. From the experiments, we observed that the proposed method could produce good cells for the machine cell formation problem.

The machine-part group formation(MPGF) problem arises frequently in FMS planning. By viewing the problem as one of finding good assignments, a powerful solution algorithm is presented. The new algorithm solves the threshold dilemma found in previous solution procedures employing similarity coefficients. It also compared favorably with other existing MPGF algorithms by finding minimum exceptional elements for the tested problems. Furthermore the new algorithm can solve dynamic and more realistic MPGF problems by considering production volumes or costs. Such diverse machine-part relationship values were not considered in previous MPGF studies, which included only 0,1 incidence values. An example problem is solved where production volumes are the elements of MPGF incidence matrix.

In this paper, an optimal group control for elevator systems is proposed with timed Petri net based approach. Elevator system is modeled by time Petri nets and hall call response times are estimated with moment generating functions (MGFs) methos, which is applicable to real traffic patterns. Two assignment policies are proposed to satisfy the demands of passengers(i.e. hall/car calls) and to handle exceptional situations. In addition, optimal algorithms are implementated to minimize cost functions. THe performances of the elevator system employing the proposed algorithms are compared with each others in ways of several performance measures by a computer simulation.

Let a finite group R act smoothly on a closed manifold M. We assume that R acts freely on M except a union of closed submanifolds with codimension at least two. Then, we show that there exists an isomorphism between equivariant topological complex vector bundles over M and nonequivariant topological complex vector orbibundles over the orbifold M/R. By using this, we can classify nonequivariant vector orbibundles over the orbifold especially when the manifold is two-sphere because we have classified equivariant topological complex vector bundles over two sphere under a compact Lie group (not necessarily effective) action in [6]. This classification of orbibundles conversely explains for one of two exceptional cases of [6].

This study was conducted to investigate the dietary behaviors and health-related lifestyles, according to exercise habits, of female university students in the Jeonju area. Self-administered questionnaires were collected from 285 students, and the statistical data analysis was completed using the SPSS v. 10.0 program. The results are summarized as follows. The weight, height, and BMI averages of the regular exercise and non-exercise groups were 53.05 kg, 162.46 cm, and 20.23, and 50.81 kg, 161.46 cm, and 19.48, respectively. The breakfast skipping ratio was higher in the non-exercise group than the exercise group. More than 72% of the exercise and 71% of the non-exercise group responded to regularly having lunch at the university canteens or restaurants around campus. Approximately 70% of the exercise and 71% of the non-exercise group responded to having dinner irregularly, which was mainly caused by reasons such as 'irregularity of life style' and 'appointments with friends'. The snack intake ratios of the exercise and non-exercise groups were high, but the exercise group ate more fruit, yogurt, and milk than the non-exercise group. The favorite sports of the exercise group were 'walk(jogging)', 'yoga', 'bicycle,' 'swim,' etc. In particular, 5.3% of the exercise group had ridden a bicycle to the university. More than 97% of the students were non-smokers. About 14% of the exercise and 15% of the non-exercise group rank alcohol once or twice a week. The exercise group did not show exceptional health-oriented dietary behaviors in comparison to the non-exorcise group. Therefore, an exercise-oriented nutrition education program would be beneficial to the students, in order to improve their dietary behaviors and health-related lifestyles.

Reactive disorder is a group of diagnosis with a definitely known etiology and whose etiological factor is essential to the diagnosis. In DSM system, such reactive disorders are listed as adjustment disorder, acute stress disorder, brief psychotic disorder with marked stressor and posttraumatic stress disorder (PTSD). However, a growing number of individuals is suffering from a prolonged feeling of embitterment after exceptional negative life events and this condition could be diagnosed neither PTSD nor adjustment disorder nor depressive disorder in the context of DSM-IV diagnostic system. This clinical condition can be described as 'posttraumatic embitterment disorder' (PTED). PTED is a reactive disorder triggered by exceptional, though normal negative life events such as conflict in the workplace, unemployment, death of a relative, divorce, severe illness, or experience of loss or separation. The common feature of such events is that they are experienced as unjust, as a personal insult, accompanied by psychological violation of basic beliefs and values. The central psychopathological response pattern in PTED is a prolonged feeling of embitterment. In particular, the core emotion of embitterment can lead to the rejection of treatment. Therefore, "wisdom therapy" as a new treatment approach specifically designed for PTED has been developed. It is assumed that many patients suffering from PTED are often misunderstood and misdiagnosed. This review would help to introduce PTED into the clinical field in psychiatry.
