  • IL-1${\alpha}$ and TNF-${\alpha}$ play an important role in initiating and coordinating the cellular events that make up the immune response to infection. The purpose of this study was to examine the effects of proinflammatory cytokines on mineralization and HO-1 protein expression in the human pulp cells. Human pulp cell cultures between the fifth and sixth passage were used in this study. Alkaline phosphatase and osteonectin were selected as markers for mineralization that is, odontoblast-like differentiation.(omitted)

  • This paper is intended to describe the idiosyncratic aspects of the 'let alone' construction in English, clarifying the productivity property of this construction and to show that this construction displays the properties of prepositional phrase that denote the meaning of 'the comparison of degree', against the claim that this construction should be regarded as a coordinating conjunction. In the process of doing that, this paper classifies this 'let alone' construction into two types of construction, by investigating the external and internal syntactic distributions of 'let alone' constructions as well as the relationship between 'let alone' phrases and the main clause.

  • Compounds containing a nitrone moiety were designed, synthesized and evaluated as a new type of active site zinc ligating substrate analog inhibitors for carboxypeptidase A. The kinetic results indicated that they are competitive inhibitors for the enzyme, supporting the design rationale that the oxygen of the nitrone forms a coordinative bond to the active site zinc ion. The present study demonstrates that nitrone is useful as a zinc coordinating ligand in the design of inhibitors for zinc containing proteolytic enzymes.

  • The scheduling problem of large products like ships, airplanes, space shuttles, assembled constructions, and automobiles is very complex in nature. To reduce inherent computational complexity, we often design scheduling systems that the original problem is decomposed into small sub-problems, which are scheduled independently and integrated into the original one. Moreover, the steep growth of communication technology and logistics makes it possible to produce a lot of multi-nation corporation by which products are produced across more than one plant. Therefore vertical and lateral coordination among decomposed scheduling systems is necessary. In this research, we suggest an agent-based coordinating mechanism for multi-level scheduling systems in supply chain. For design of a general coordination mechanism, at first, we propose a grammar to define individual scheduling agents which are responsible to their own plants, and a meta-level coordination agent which is engaged to supervise individual scheduling agents. Second, we suggest scheduling agent communication protocols for each scheduling agent topology which is classified according to the system architecture, existence of coordinator, and direction of coordination. We also suggest a scheduling agent communication language which consists of three layers : Agent Communication Layer, Scheduling Coordination Layer, Industry-specific Layer. Finally, in order to improve the efficiency of communication among scheduling agents we suggest a rough capacity coordination model which supports to monitor participating agents and analyze the status of them. With this coordination mechanism, we can easily model coordination processes of multiple scheduling systems. In the future, we will apply this mechanism to shipbuilding domain and develop a prototype system which consists of a dock-scheduling agent, four assembly-plant-scheduling agents, and a meta-level coordination agent. A series of experiment using the real-world data will be performed to examine this mechanism.

  • Purpose of this study was to identify the effects of a clinical basic nursing practice of the nursing students on the clinical competency.Method: The subjects of this study were 154 fresh nursing students(experimental group) in second semester of G college who have had the clinical basic nursing practice in a clinical setting, and 148 fresh nursing students(control group) in second semester of A college who have not had the clinical practice. Data for this study were collected from September 19 to December 5, 2001 with a questionnaire which was consisted of three measuring tools, these are Basic Nursing Skills (36 items) of Yoo(1992), Teaching / Coordinating (6 items) and Professional Attitudes (7 items) of Lee et al.(1990), and Self-esteem (10 items) of Ronsenberg(1965).Result : 1) The experimental group showed statistically significant higher clinical competency than the control group.2) Moreover, the experimental group showed the higher scores than the control group significantly in all the detail areas, those are basic nursing skill, teaching & coordinating, professional attitudes and self esteem.Conclusion : As the results of the study shown, the clinical practice on basic nursing for fresh nursing students in second semester of college shall contribute to develop their clinical competency. So Nurses graduating from college with the higher clinical competency are expected, if the clinical institutions and nursing colleges try to cooperate in this area continuously.

  • This study was carried out by using questionnaires with 126 insurance societies from Sept. 30, 1995 to Oct. 18, 1995. The primary data collected bythe survey have been significantly supplemented by secondary data obtained from sources such as health insurance statistical year books and internal data in the Ministry of Health and Wolfare. Major findings were summarized as follows: Two financial coordinating programs have significantly improved financial status of regional health insurance societies: the catastrophic program for high cost medical care that was initiated in 1991 and the program for hospitalization cost of the aged in 1995. Another finding is that there existed ambiguity and inconsistency of equity index that had been used by stabilization programs and its side effects could not be ignored. Regression analyses were made to identify factors that affect financial transfers. Inde pendent variables in the regression include utilization frequency, dependancy ration, insurance contribution per insured and medical expense per insured. All these variables were statistically significant in the equations of applying distribution rate (distribution/contribution) and transfer rate (transfer/contribution) as dependent variables. Policy suggestions for the catastrophic program for high cost medical care are modifying the definition of catastrophic case and setting the maximum amount of subsidies for each society based on distribution rates. To solve the problems of the financial coordinating program for the aged, we could consider reimbursing more than 50% of the copayment incurred by the aged 65 or more and determining the maximum amount of outpatient copayment at 10,000 Won per day or per visit for the elderly. More fundamental improvement could be made by amending the Welfare Benefit Act to establish and expand medical and welfare facilities for the elderly.

  • Background: The musculoskeletal disorders with asymmetrical gait on the whole body are the most common. This study was designed to analyze that General Coordinative Manipulation Intervention Models would affect the balanced restoration of asymmetrical gait. Methods: 68 healthy volunteers(1st hypothesis: 46, 2nd hypothesis 22) participated in the two GCM intervention models, which have performed 2 times a week for 3 weeks. Digital Camera was used to measure the gait, and measurements were performed before and after the application of the each intervention model. Repeated measured ANOVA was used to determine a statistical significance. Results: The outcome of examining hypothesis is as follows: 1. The 1st hypothesis : GCM Intervention based on the coordinating the flexion type of upper body and the extension type of lower body will improve in the balanced restoration of asymmetrical gait because it offers a clear direction for treatment(p<.05). 2. The 2nd hypothesis: GCM Intervention based on the coordinating the flexion type of lower body and the extension type of upper body will improve in the balanced restoration of asymmetrical gait because it offers a clear direction for treatment(p<.05). Conclusion: GCM intervention programs on the two hypothesis groups have effects on the balanced restoration of asymmetrical gait(p<.05).
