Objective To evaluate the long-term outcomes, including the pregnancy outcome and recurrence rate after single-port laparoscopic myomectomy (LM) using a modified suture technique with a Hem-o-lok clip (Choi’s LM) and conventional 4-port LM. Methods A retrospective study of patients who underwent Choi’s LM (n=55) and 4-port LM (n=102) in a single institutional hospital was conducted. Patients with <3 symptomatic myomas sized <10 cm each and operated on by a single surgeon were included. Recurrence was confirmed when a myoma measuring ≥3 cm was detected. Results The patients in both groups had similar demographic characteristics. Single (76.4% vs. 62.7%) and intramural (52.7% vs. 56.9%) tumors were commonly detected in both groups in the mean diameter (6.8±1.5 cm vs. 7.0±1.6 cm; P=0.40). In Choi’s LM, 16 patients (29.1%) needed an additional port; those who were nulliparous and/or had a large leiomyoma more frequently required an additional port (P=0.023 and 0.04, respectively). During a median follow-up period of 69 months, 17 patients (7.1% vs. 14.6%) had recurrence. The size of dominant myomas at recurrence was significantly smaller in patients who underwent Choi’s LM (3.4±0.7 cm vs. 5.7±2.4 cm; P=0.004). All 13 patients in both groups who successfully conceived had a full-term delivery. No major complications occurred during pregnancy. Conclusion Although an additional port was frequently used, the long-term outcomes of patients who experienced recurrence and pregnancy after Choi’s LM were acceptable. Considering its usability, Choi’s LM is feasible for the treatment of uterine leiomyoma.

As the internationalization of enterprising business enlarged the extent of intervention of enterprises, the importance of world market in the enterprising business is growing every day. Multinational enterprises that target the world market have to determine whether they should adapt the marketing mix strategy to each country or standardize it universally. The controversy on the standardization or the adaptation of strategy is especially active in the field of products and advertising. Since the possibility of standardization of multinational advertising which is an essential component of marketing mix insisted by Elinder in early 1960, the controversy on this matter in 1980's. Levitt refuted the argument of adaptation and maintained that the consumers in the world have been homogenized by the development of technology. Thus multinational advertising not only establishes the universal image of specific products but it also reduces the production costs of advertising. The subject that the advertising strategy of Korea applies to other countries should be studied seriously for the provision against the fact that Korea has become a leading exporter and that the advertising of Korean brands will be exposed in the near future. This study will survey the controversy on the standardization versus customization of multinational advertising among many researchers. It will present a conceptual model of the standardization of advertising through the scientific and theoretical approach to advertising. It will also present to the consumer an interdisciplinary approach to the method of comparison.

The conventional PI control that are used in the control loop for outer speed of the induction motor, also has difficulty dealing with the dynamic speed tracking parameter variation and the load disturbance. As a result, the motion control system operates with a poor performance in the motor's low speed range. In this dissertation a novel speed control system that implements and fuzzy logic controller(FLC) is proposed. The proposed FLC used the speed error its rate of change and the drive current as three fuzzy variables. The real command output current is chosen by the dufuzzification of the fuzzy output extracted from the fuzzy control rules. The flux and the torque of the induction motor are estimated using the dynamic model with an excellent dynamic response over a wide speed range and with the rotor flux field-oriented scheme of the decoupling characteristics. The performance of this control system is substantiated by computer simulations.

A study on the determinants of consumer demand is generally dealt with the traditional consumer theory from the viewpoints of micro-economics. But in realty consumer demand depends on many factors besides price factor on basis of micro-economics. Therefore, the purpose of the present study is to reestablish the system of consumer behavior by analyzing on the determinants of consumer demand from the viewpoints of micro-economics, macro-economics, and managerial administration. As a result this study can be summarized as follows: First, from the viewpoints of micro-economics on basis of price factor, consumer demand depends on mutual relations of consumers, namely consumers actually behaviors on the bandwagon effect, snob effect, and veblen effect. Second, from the viewpoints of macro-economics on basis of income factor, consumption is determined by absolute income, relative income, permanent income, long life income and so forth. Third, from the viewpoints of manageiral administration, a study on the consumer behavior can be classified by social, cultural factor and individual, psychological factor. From the above mentioned facts, finally the determinants of consumption can't be discussed with the social economic situation. Therefore the determinants of consumption must be analyzed completely from the viewpoints of social science in future. In additions the determinants of consumption suggested in this present study must be tested empirically and measurements for this purpose must be developed.

As the internationalization of enterprising Business enlarged, the extent of intervention of enterpises, the importance of world market in the enterprising business is growing everyday. Multinational enterprises which make the world market of a target market have to determine whether they adapt the marketing mix strategy to each country or they standardize it universally. The controversy on the standardization or the adaptation of strategy is especially active in the field of products and advertising. Since the possibility of standardization of multinational advertising which is an essential component of marketing mix insisted by Elinder in early 1960, the controversy on this matter had continued for about 20 years and it was Levitt who interested again the people in this matter in 1980's Levitt confuted the argument of adaptation and main tamed that the consumers in the world have been homogenized by the development of technology. Thus the multinational advertising not only makes the universal image of specific products but also reduces the production cost of advertising. The subject that the advertising strategy of Korea applies to other countries should be studied seriously for the provision against the fact that Korea has grown a leading exproter and that the advertising with Korea brand will be exposed in the near future. This study will present a conceptional model of the transferability of advertising through the scientific pecularity of the advertising theorical approach to the consumer behavior and to the communication and interdisciplinary approach to the method of the comparative cultural approach and will research and analyse according to the product pecularity and the modes of advertising appeal whether Korean advertising can be transferred into the united states.

This paper is an attempt to propose our study that draw up a plan about faculty and major course to the Daegu Polytechnic College authorities. Our approach is a mixture of methods. It is systematic, in that it attempts to treat a college as a system. Through the second chapter, we examine the periodic, social, environmental, governmental, and economic context within which the College's developing effort must progress. Chapter three examines how the college systems actually design about faculty and major course. Thus, chapter four discusses how new faculty and major course participants attempt to compose a curriculum; chapter five accesses the institutions available in the College to distribute these designs. In conclusion, this paper presents that the College system would be better nine faculty; education and nurse·health field only be in administration unit, an information field be better divided into two parts: internet computer and information communication, and business and computer design faculty is established as intimate information. After all, the system will be characteristic in its information traits.

Digital technical renovation and rapid development of internet and super communication technologies have dramatically influenced on trends of our society over the cyber space and college is necessary to be reformed against such current innovation to keep up with advanced technologies and skills for digital and communication fields. For this reason, initial efforts were focused on extending development of infra structraul systems to operate efficient recruitment of enterance college, college advertisement, educational strength, industrial-educational cooperation, job oppertunities, financial support which are currently confronted with. Such efforts also can be alternative way to be a future direction as long-term plans of our college. In this report, we suggest plan for collective and long-term schemes against current college problems Moreover, even though a proposed plan as first step is to limit to Susung-Ku area, this system for practical application and harmony can be applied to other county areas without any additional investment and efforts in the future.

Objectives : This study aimed to describe the demographic, clinical and offense characteristics of the patients with Schizophrenia who committed parricide. This study also investigated the risk factors of parricide by comparing with characteristics of stranger killers to prevent the tragic offense. Methods : The sample consisted of 88 schizophrenic patients who committed homicide, 59 of them committed parricide and 29 of them killed strangers. Medical chart review regarding demographic and clinical characteristics as well as offense Characteristics was conducted. The information that was difficult to be obtained through chart review was acquired by direct interview. Results : Parricide group had earlier age of onset, more conflicts with the victims, more violence history toward victims and more offense provoking events than stranger killing group. Parricide group showed higher rate of past treatment than that of stranger killing group. However drug compliance at the time of offense was low in both groups. Offense provoking events in the parricide group included blaming, threatening a forced hospitalization or medication toward patients. The most common Psychiatric symptoms associated with homicide were threat/control override (TCO) symptoms, delusional perception, commanding auditory hallucination and especially with parricide, Capgras syndrome (CS). Conclusion : Interaction between psychotic symptoms such as TCO, CS and underlying emotion toward victims are likely to be associated with parricide. Mental health professionals are expected to play an important role in preventing this tragic offense by active history taking of the violence and effective management with active caregiver education/intervention of intrafamilial conflicts.
