This is a study of care-oriented morality and justice-oriented morality among middle-aged adults. Thirty seven males and forty six females between the ages of 45 and 59 years old participated in this study Care-oriented morality was measured by the Ethic of Care Interview(ECI) while the justice-oriented morality was assessed using the Korean Defining Issues Test(DIT). Sex role identification was interpreted by using the Korean Sex Role Inventory(KSRI). In terms of care-oriented morality, the majority of the subjects were at level 2. The P(%) score of justice-oriented morality was found to be a little low. We found a significant difference between genders in terms of care-oriented morality, with females exhibiting a higher care-oriented morality. However, there was no significant difference in sex role identity types in terms of care-oriented morality. Nor did we find a significant interaction effect between gender and sex role identity. There was no gender difference in justice-oriented morality, but there was a significant difference among sex role identity types. Masculine males Possess the highest justice-oriented morality. A significant interaction effect was found to exist between sex role identity and gender.

In order to design the aspherical lens, the revisions and the steps of the mathematical method are influenced with a lot of variables. The accuracy of the aspherical lens can be changed by these variables. Besides, to design the aspherical lens, many mathematical functions should be used. To use these mathematical functions is protected by patent administration. Therefore it is very difficult for most of developed countries to use them. This fact has been interrupting not only the development of the technique of a design of the aspherical lens but also the development of the equipments of optics. Because approximate values are used in most of common programs which create the aspherical lens : basically these common programs have variations. Therefore these aspherical lens are not accurate. In the paper, we calculated accurate values by using the refractive index of lens. Based on these data, wee created self-operating design programs. Consequently, our lens is more accurate than the aspherical lens which is created by the common programs influenced with approximate values. The used programs belonging to AutoCAD is Visual LISP.

This paper proposed the safety helmet monitoring system based on USN(Ubiquitous Sensor Networks) to secure the wear of helmet for labor on the construction area. As one of the most significant gear to assure labor's safety, The safety helmet would have the extend of labor's injuries minimized whether one wears or not when an accident takes place. At this point, we have developed and demonstrated the system which is able to check who wear the safety helmet properly for labors, composed of safety helmets with sensor node, router nodes, sink node and management program. Moreover, we could show optimized parameters for the proposed USN system as doing experiment and demonstration, we expected that this system would make for labor wear the safety helmet properly on the construction area as well as prevent economic injury caused by an accident with not wearing for labors.

X.500 Directory is an application level protocol in the Open Systems Interconnection(OSI) 7 layer's reference model adopted by the international Standards Organization (ISO). It manages effectively needed information for the communication service, and is a service to support the functions that the user can approach conveniently. Tourist information is distribution on several locations. The access of distributed information is similar to X.500 directory service. Therefore, we design of Tourist Information System(TIS) and directory schema using X.500 directory services. To define tourist information, we also propose Directory Information Tree(DIT) of locality architecture and several new object classes, such as museum, mountain, sea, hotel, etc.

Thermally grown gate oxide on 4H-SiC wafer was investigated. The oxide layers were grown at l150$^{\circ}C$ varying the carrier gas and post activation annealing conditions. Capacitance-Voltage(C-V) characteristic curves were obtained and compared using various gate electrode such as Al, Ni and poly-Si. The interface trap density can be reduced by using post oxidation annealing process in Ar atmosphere. All of the samples which were not performed a post oxidation annealing process show negative oxide effective charge. The negative oxide effective charges may come from oxygen radical. After the post oxidation annealing, the oxygen radicals fixed and the effective oxide charge become positive. The effective oxide charge is negative even in the annealed sample when we use poly silicon gate. Poly silicon layer was dope by POCl$_3$ process. The oxide layer may be affected by P ions in poly silicon layer due to the high temperature of the POCl$_3$ doping process.

Purpose: The purpose of this study was to compare the effects of CEDA (Cross Examination Debate Association) debate with those of traditional lecture education on moral judgment and ethical values using the Korean version of DIT and the ethical values. Methods: The experiment was performed for 9 weeks, from September 2 to November 12, 2010. Participants were 71 undergraduate nursing students in a nursing college, assigned to an experimental group (36 students) or a control group (35 students). The design of this study was a non equivalent control group pretest-posttest design. Results: The experimental group reported significantly higher scores of the 4 stage scores of moral judgment (t=-2.19, p=.036) and ethical values (t=3.04, p=.004) than the control group. However, no significant differences were found in the P score of moral judgment between the two groups. Conclusion: The findings of this study showed the benefits of providing a CEDA debate course for nursing ethics education. Therefore, in further studies, it is necessary to develop various teaching strategies or educational programs to improve nursing ethical values and moral judgment.

현재 MOS 소자에 사용되고 있는 $SiO_2$ 산화막은 그 두께가 얇아짐에 따라 Gate Leakage current와 여러 가지 신뢰성 문제가 대두되고 있고, 이를 극복하고자 High-k물질을 사용하여 기존에 발생했던 Gate Leakage current와 신뢰성 문제를 해결하고자 하고 있다. 본 실험에서는 High-k(hafnium) Gate Material에 온도 변화를 주었을 때 여러 가지 전기적인 특성 변화를 보는 방향으로 연구를 진행하였다. 기본적인 P-Type Si기판을 가지고, 그 위에 있는 자연적으로 형성된 산화막을 제거한 후 Hafnium Gate Oxide를 Atomic Layer Deposition (ALD)를 이용하여 증착하고, Aluminium을 전극으로 하는 MOS-Cap 구조를 제작한 후 FGA 공정을 진행하였다. 마지막으로 $300^{\circ}C$, $450^{\circ}C$로 30분정도씩 Annealing을 하여, 온도 조건이 다른 3가지 종류의 샘플을 준비하였다. 3가지 샘플에 대해서 각각 I-V (Gate Leakage Current), C-V (Mobile Charge), Interface State Density를 분석하였다. 그 결과 Annealing 온도가 올라가면 Leakage Current와 Dit(Interface State Density)는 감소하고, Mobile Charge가 증가하는 것을 확인할 수가 있었다. 본 연구는 향후 High-k 물질에 대한 공정 과정에서의 다양한 열처리에 따른 전기적 특성의 변화 대한 정보를 제시하여, 향후 공정 과정의 열처리에 대한 방향을 잡는데 도움이 될 것이라 판단된다.
