When people undergo stressful situations such as a cancer diagnosis, they ask, "why me\ulcorner" The causal attributions people make about cancer influence what kind of coping strategies are chosen. Weiner (1979) suggested three dimensions of causal attributions: focus of causality, stability, and controllability. The purpose of the present study was to test the relation between causal attributions and self-efficacy in patients with cancer. The subjects were 194 patients who had been diagnosed cancer one year ago and attended an outpatient clinic. 1. Each mean score of causal attribution dimensions (focus of control, stability, controllability) that each patient made about cancer was 2.47, 2.73, 2.86, 3.35, and 3.28. The mean score of self-efficacy was 71.03. 2. There was a significant negative correlation between self efficacy and controllability. Particularly, there was a significant negative relationship between self efficacy and external controllability. Based upon these results, it is recommended that the developing nursing interventions to change causal attribution and self-efficacy is necessary. A number of theoretical relationships and empirical finding are confirmed by this data, and future proposals in research is suggested.

Let GF(q) be a finite field with q elements where q=p$^{n}$ for a prime number p and a positive integer n. Consider an arbitrary function .phi. from GF(q) into GF(q). By using the Largrange's Interpolation formula for the given function .phi., .phi. can be represented by a polynomial which is congruent (mod x$^{q}$ -x) to a unique polynomial over GF(q) with the degree < q. In [3], Wells characterized all polynomial over a finite field which commute with translations. Mullen [2] generalized the characterization to linear polynomials over the finite fields, i.e., he characterized all polynomials f(x) over GF(q) for which deg(f) < q and f(bx+a)=b.f(x) + a for fixed elements a and b of GF(q) with a.neq.0. From those papers, a natural question (though difficult to answer to ask is: what are the explicit form of f(x) with zero terms\ulcorner In this paper we obtain the exact form (together with zero terms) of a polynomial f(x) over GF(q) for which satisfies deg(f) < p$^{2}$ and (1) f(x+a)=f(x)+c for the fixed nonzero elements a and c in GF(q).

기존의 대표적인 디지털 통신방식으로 주파수 편이 변조(FSK: frequency shift keying), 위상 편이 변조(PSK: phase shift keying), 진폭 편이 변조(ASK: amplitude shift keying) 방식들이 있다. 본 논문에서는 2진 정합필터를 이용하여 웨이브릿 편이변조 신호를 복원하는 알고리즘을 제안한다. 웨이브릿 편이 변조 시스템은 스케일링 함수(scaling function)와 웨이브릿(wavelet)을 이용한다. 스케일링 함수를 1로, 웨이브릿 함수를 0으로 할당하여 2진 데이터를 변조한다. 기존의 웨이브릿 편이 변조 시스템에서는 복원을 위해 후처리가 필요하였다. 된 논문에서는 2진정합필터를 이용하여 복원하므로, 별도의 후처리 과정 없이 복원을 가능하게 하였다. 모의실험 결과 제안한 알고리즘이 타당함을 확인하였다.

A stochastic modeling of combat that takes more realistic situations into account has been studied with deep concern. Either the firing strategies or network formations are very important elements in the analysis of combat. The first objective of this study is to evaluate how the different strategies affect the outcomes of combat. An analytical approach has been used in an attempt to understand a small-sized battle. The results are validated and compared with existing simulation models. Extending to the moderate size of battle may be achieved with ease. Secondly, an attempt has been made to study and investigate a way to solve combat in a different fashion. We divided a two-on-two battle into two separate one-on-one battles and connected them into a network. New elements considered such as delay time of starting a firefight on a particular node or search time for the next target when a kill occurs are defined and used as the input parameters. The discussions are made to validate the hypothesized model and ask if the results are meaningful and useful in the analysis of combat operations or not.

The purpose of this study was to investigate to wearing practices and consumer needs for stockings. 503 subjects were surveyed in 2002. Data were analyzed by frequency, $\chi$$^2$, ANONA(LSD) and factor analysis. The results were as follows; 1) Many subjects considered the colors, but a very few of them considered the components and handling signs when purchase their stockings. These tendencies show meaningful differences according to their ages, jobs and the status of whether they are married or single. The wearing rates of stockings show differences according to their physical characteristics and social demographical variables. 2) They demand that the exact fiber contents and the mixture ratios which the stockings have should be indicated, and also want the sizes of the stockings to be indicated by three steps according to their body sizes, and they ask that the stockings have more various colors. They required that the stockings should have good ventilation, durability, warmth-keeping, hygroscopicity and elasticity in leg parts, and anti static electricity or bacteria.

The relationship between selenium and signal molecules is not well elucidated yet. It was found that physiological concentration of selenite, less than 3 $\mu$M, reduced ASKl activity and induced of PI3-Kinase/Akt pathways in HT1080 cells. Duration of these signal molecules by selenite was much longer than that by growth factors and other stresses. The longer duration time of these signal molecules may be important to maintain normal functions against stresses.(omitted)

When you act for a good or just when you make a choice, you should ask yourself if the result of your action coincides with the principle that has generated it. Health and respect for our own individuality are two essential goods for the human being and also values that medicine itself should guard carefully remembering that its goal is to take care for a person and not only to cure a sick body. The means to achieve all this can only be a person-centered medicine which has the honor and the burden of considering the person (in the Kantian sense) and his health as an end, not a means. The current mainstream concept of health defined in 1948 by the World Health Organization as a state of complete mental, physical and social wellbeing and not merely the absence of disease and infirmity remind us that medical reasoning, based on the pathogenesis operator, is no longer sufficient in dealing with requests from the citizens: is now the right time to shift the focus from sickness to health giving emphasis to the salutogenic medicine approach.

Various applications, such as mesh composition and model repair, ask for a natural stitching for polygonal surfaces. Unlike the existing algorithms, we make full use of the information from the two feature lines to be stitched up, and present an accurate stitching method for polygonal surfaces, which minimizes the error between the feature lines. Given two directional polylines as the feature lines on polygonal surfaces, we modify the general placement method for points matching and arrive at a closed-form solution for optimal rotation and translation between the polylines. Following calculating out the stitching line, a local surface optimization method is designed and employed for postprocess in order to gain a natural blending of the stitching region.

In the hot summer manual spray work for plants would be the hardest one among the agricultural field works. Besides the physical load the possible toxication would strongly ask a way to do the job on behalf of human. Although an aircraft with sprayer could be a good candidate, the manned airplanes do not play proper roles in our country because of field geometry. Today, unmanned helicopter as expensive as 200,000 dollars can do the job with high risk of control. Therefore safe and cheap air vehicle with sprayer, if developed, could be a great help to agriculture.

This paper is aimed to investigate the applicability of SMG method to the development of an object-oriented simulation software in the MODSIM II environment. SMG method is an object-oriented simulation software development method proposed by System Modeling Group(SMG), National Defense University of Korea. Through this study, we concluded that SMG method can be a powerful method for the development of object-oriented simulation software in the MODSIM II environment. However, SMG method lacks in depicting some of messages in the MODSIM II, for example, ASK method, TELL method, WAITFOR method, interrupt. In the future, SMG method is expected to extend for incorporating those things presumably by referring to Professor Baileys pictures, OOSPICs.
