In providing general medical treatments, the medical service contract between the patient and the doctor is the mutually responsible onerous contract. However, the nature of the mutually assumed contract standings of the patient and the doctor has been changing since the implementation of the national health insurance program. For instance, besides the cases of beyond excessive medical charges and medical negligence, if the doctor charged for his/her medical treatments violating the post-treatment/nursing cover criteria, the overpaid medical charge, regardless of being collected with the patient's consent, has to be refunded back to the patient. Medically needed aspects, treatment results, and unfair benefits favoring the patient are not at all taken into consideration in the health insurance scheme. This makes it easier for patients to get refunds for their share of the medical payments by involving the Health Insurance Review & Assessment Service or the National Health Insurance Corporation, without engaging in civil law suits (for reimbursement claim) against doctors. In other words, the doctor's responsibility to provide medical treatments and the patient's responsibility to pay for the medical treatment provided within the contractual realm are being demolished by the administrational arbitration of the National Health Insurance system. The basic rights of medical service providers, and the patient's right to choose are as important constitutional rights, as the National Health Insurance program, which is essential in the social welfare system. Furthermore, the development of the medical fields should not be prevented by the National Health Insurance system. If the medical treatment services can be divided into necessary treatments, general treatments, and high quality treatments, the National Health Insurance is supposed to guarantee the necessary and general treatments to provide medical treatments equally to all the insured with limited financial resources. However, for the high quality treatments, it is recommended that they should not be interfered by the National Health Insurance system, and that they should be left to the private contract between the patient and the doctor.

The purpose of this study is to assess the extent of inequality in health outcomes and the distribution of health services according to health need under National Health Insurance System in Korea. For the empirical analysis, data were collected through an interview survey during one month of October, 1994. Interview were conducted with a total of 10, 875 of the employees and the self-employed selected through cluster, systematic sampling. The major findings of this research are as follows: 1. The analysis of the differentials in morbidity rates by socio-economic group showed that health inequality in the pro-higher groups existed in all self-reported morbidity indicators. 2. The findings of the conventional use measures showed that the lower socio-economic groups had more ambulatory and inpatient services than the higher groups. In contrast to the level of the medical care utilization, however, the higher socio-economic groups were more likely to use the high-quality source of care in terms of their treatment place compared to the lower groups. 3. By using the need-based use measures, the results were different from each use-disability ration indicator. Using the use-disability ration measured by physician visits per 100 restricted-activity days in the population, it was found that there was no evidence favoring the higher socio-economic groups. In contrast, the use-disability ration based on physician visits per a chronic patient in one year displayed that there was remarkable relative difference by income group as well as the evidence of the pro-higher income groups. 4. The results of logistic regression analysis and two-stage estimation method indicated that although the utilization is significantly affected by type and duration of insurance coverage, the use or nonuse of service and the volume of physician care consumed is determined by health need and demographic characteristics rater than economic status. In sum, these findings suggest that physician service is equitably distributed according to health need under national health insurance system in Korea. As there were some evidences of inequality including the differential in physician visits of chronic patients by income group, however, the government should strengthen the activities to guarantee the equity of health services utilization.

The concept of self efficacy, originally theorized by Bandura, has been applied to a wide variety of fields including education, psychology, and business. There has been steady effort to develop relevant scales to operationalize and measure self efficacy. This article reports on the results from an analysis of Kurbanoglu's ILSES (Information Literacy Self-Efficacy Scale), the only reported such scale in the area of information literacy. Over 400 university students responded to the ILSES survey consisting of 40 items grouped in six categories. The main analysis used was factor analysis. The results show high degree of internal consistency of the items included. However, the factors derived from the study differ significantly from the factors in the original study. Overall, these factors seem to reflect the heuristic nature of students' information seeking and use patterns, favoring Internet resources and instant gratification.

As an environment-friendly alternative energy resource, ethanol may be used to obtain hydrogen, a clean energy source. Thus, studies on catalytic reactions involving ethanol have been studied to understand the underlying principles in the reaction mechanism using various oxide-supported catalysts. Among them, Au-based catalysts have shown a superior activity in producing hydrogen gas. In the present study, Au/$TiO_2$ catalysts were prepared by deposition-precipitation method to understand their catalytic activities toward ethanol and acetaldehyde with increasing gold loading, especially at the very low Au loading regime. A commercially available $TiO_2$ (Degussa P-25) was employed and the Au loading was varied to 0, 0.1, 0.5, and 1.0 wt% respectively. The catalysts showed characteristic x-ray diffraction (XRD) features at $2{\theta}=78.5^{\circ}$ that could be assigned to the presence of gold nanoparticles. Its reactivity measurements were performed under a constant flow of ethanol and acetaldehyde at a flow rate of ${\sim}0.6{\mu}mol/sec$ and the substrate temperature was slowly raised at a rate of 0.2 K/sec. We observed that the overall reactivity of the catalysts increased with increasing Au loading along with selectivity favoring dehydrogenation to product hydrogen gas. In addition, we disclosed various reaction channels involving competitive reaction paths such as dehydrogenation, dehydration, and condensation. In addition, subsequent reactions of acetaldehyde obtained from dehydrogenation of ethanol, were found to occur and produce butene, crotonaldehyde, furan, and benzene. Based on the results, we proposed overall reaction pathways of such reaction channels.

Background: Ketorolac($Tarasyn^{(R)}$) is a non-steroidal anti-inflammatory drug(NSAID) which has shown to be an effective postoperative analgesic available parenterally, and when combined with morphine can reduce its requirement. The analgesic efficacy and adverse effects of continuous infusion of ketorolac added to morphine IV PCA was evaluated in 60 women after abdominal hysterectomy. Methods: Patients were assigned to receive either morphine intravenous(IV) bolus followed by morphine IV patient controlled analgesia(PCA), or ketorolac 30mg IV and continuous IV infusion at 4.0mg/hr in combination with the above regimen. The authors evaluated PCA morphine used, pain assessment(verbal pain intensity score and visual analogue scale) and side effects at 2, 4, 6 and 24hrs during pain control. Results: Continuous infusion of ketorolac decreased the PCA morphine usage significantly(30.4 ---> 19.6 mg : p=0.007) at 24hrs postoperatively. Significant differences were seen favoring ketorolac infusion in pain intensity and visual analogue scale both at rest and during movement. There were no differences in incidences of deep sedation, nausea & vomiting. But the ketorolac group they complained of dizziness more than morphine only group. Little pruritus was recorded in either groups. Conclusions: The authors conclude continuous IV infusion of ketorolac in conjunction with morphine PCA provide effective analgesia after low abdominal surgery.

The study aims to explore the impacts of types of consumer's self-construal, prices of brands, and types of discount-based sales promotion on consumers' purchase intention. For this study, a three-way mixed factor method was applied based on a formula, types of consumer's self-construal x prices of brands x types of discount-based sales promotion. The subjects were 218 females in their 20s to 30s living in seoul or Gyeonggi-do areas. For data analysis, three-way variate analysis, analysis of simple interactions and analysis of simple main impacts were conducted through use of the SPSS program. First, based on the impacts of types of consumer's self-construal, prices of brands, and types of discount-based sales promotions in the favor of consumers, there was a significant difference between higher and lower-priced brands. Second, comprehensive discounts rather than monopolistic discounts corresponded to higher favoring by consumers of interdependent self-construal. As for monopolistic discount, lower-priced products corresponded to higher favor than higher-priced ones. Third, there was a significant difference between consumers of independent self-construal and interdependent self-construal. Fourth, comprehensive discount, rather than monopolistic discount, corresponded to higher purchase intention regardless of prices of brands in the group of consumers with interdependent self-construal.

The cationic polymerization of oxolane high explosives which have pendant explosive groups such as azido, nitrato and hydrazino is investigated theoretically using the semiempirical MINDO/3, MNDO and AM1 methods. The nucleophilicity and basicity of oxolane high explosives can be explained by the negative charge on oxygen atom of oxolane. The reactivity of propagation in the polymerization of oxolane can be represented by the positive charge on carbon atom and the low LUMO energy of active species of oxolane. The reaction of the oxolane high explosives in oxonium ion form to the open chain carbenium ion form is expected by computational stability energy (17.950~30.197 kcal/mol) of the oxonium ion and carbenium ion favoring the carbenium ion. The relative equilibrium concentration of cyclic oxonium ion and carbenium ion is found to be a major determinant of mechanism, owing to the rapid equilibrium of these catoinic forms. Based on calculation, in the prepolymer propagation step, $S_N1$ mechanism will be at least as fast as that for $S_N2$ mechanism.

This study attempts to analyze the spatial characteristics of cyberspace and to map spatial variations of cyberspace. In order to analyze the spatial distribution of cyberspace, three measurement indices are selected such as commercial domain number, Internet backbone network, and Internet users, which are highly correlated to each other. The three sets of measurement showed that cyberspace in Korea is spreading in a highly uneven fashion, strongly favoring a few cities and unfavoring economically distressed cities. Seoul acts on overwhelmingly dominant role in cyberspace, by being concentrated a number of domains and having high-capacity bandwidth on Internet backbone network. Internet is selectively connecting several cities into highly interactive networks, while at the same time largely bypassing other cities. The development of Internet network through infrastructure investments at selected cities has resulted in an uneven accessibility and digital divide among cities. The regional disparity would be further reinforced by ICT development as the primary vehicle for unequal accessibility. The result of this study revealed that geography continues to matter, despite the recent rhetoric claiming of 'the death of distance'or 'the end of geography'.

The prolongation of life expectancy has expanded the duration of marriage in old age. In the meanwhile, the change of life style emphasizing privacy and sociodemographic environment favoring independent living has increased the number and proportion of the elderly living with spouse only. This study, focusing on those aged 60 and over who live with spouse only the elderly, explores their marital relationship. The study pays a special attention to compare whether and how the satisfaction on the relationship with spouse would differ between husband and wife. The ordered logit model analysis is conducted based on the nationwide survey '2008 Korean National Survey of Welfare Need in the Elderly'. The results show that the marital relationship satisfaction of husbands is influenced by their own characteristics but hardly affected by his wife's. In contrast, the satisfaction of wife is influenced by husband's characteristics as well as hers. These finding reflect that women are more strongly family-centered and dependent on their husband.

The cationic polymerization of cyclic acetals are investigated theoretically using the semiempirical MINDO/3, MNDO, and $AM_1$, methods. The nucleophilicity and basicity of cyclic acetals can be explained by the negative charge on oxygen atom of cyclic acetals. The reactivity of propagation in the polymerization of cyclic acetals can be represented by the positive charge on $C_2$ atom and the low LUMO energy of active species of cyclic acetals. The reactivity of 2-buthyl-1,3-dioxepane(2-Bu-DOP) of cyclic oxonium and opening carbenium ion form is expected computational stability of the oxonium ion by 5${\sim}$7kcal/mole favoring the carbenium ion. Owing to the rapid equilibrium of these cation forms and the reaction coordinate based on calculation that the reaction coordinate based on calculation that the chain growth $S_N1$ mechanism will be at least as fast as that for $S_N2$ mechanism.
