In this paper, we propose a new performance comparison method of various Interpolation methods for image enlargement The conventional methods employs PSNR and edge characteristic evaluation for performance comparison of interpolation methods. The proposed performance comparison method uses the position Information for each difference pixel's value and the frequency characteristic information between original image and Interpolated image. The proposed methods might be useful for performance comparison of various Interpolation methods through the computer simulation.

This article presents a multiple comparison ranking procedure for several products of the Poisson rates. A preference probability matrix that warrants the optimal comparison ranking is introduced. Using a Bayesian Monte Carlo method, we develop simulation-based procedure to estimate the matrix and obtain the optimal ranking via a row-sum scores method. Necessary theory and two illustrative examples are provided.

In case of sensory evaluation with multi-samples and long-period, in spite of using method with good sensitivity, quality differences among samples could net be detected well because of panel's fatigue and tiredness. So new method to reduce panel's sense of psychological and physiological responsibility, "Trio Paired Comparison", is designed, and New Modified Scheffe's Method 2 as the statistical method for a test of "Trio Paired Comparison" is proposed. And also in this paper problems and countermeasures in applicating "Trio Paired Comparison" are considered.

We prove the maximum principle and the comparison principle of $p$-harmonic functions via $p$-harmonic boundary of graphs. By applying the comparison principle, we also prove the solvability of the boundary value problem of $p$-harmonic functions via $p$-harmonic boundary of graphs.

Recently comparison-shopping agent systems are promising to support purchase of buyers in online-shopping environment. This paper proposes a comparison-shopping agent system considered easy access and buyer's preference. Easy access is achieved by minimizing questions to buyer. Buyer's preference is considered by using pairwise comparison of products attributes. Procedure of the proposed system is explained with a case of notebook. Finally a prototype has been implemented.

In this paper, we introduce the modification of a generalized (Ψ, L)-weak contraction and we prove some coincidence point results for self-mappings G, T and S, and some fixed point results for some maps by using a (c)-comparison function and a comparison function in the sense of a b-metric space.

Purpose : This study is to examine what are the effects of the Woogwiyeum(WGY) on the ovariectomized rat model of postmenopausal osteoporosis. Methods : We devide mice to 3 Group(Sham operated group, control group, WGY treated group) and analyze each serum component. Results : 1. Body weight in control group showed significant increase in comparison with sham, but that in WGY-treated showed no change in comparison with control. 2. The level of serum albumin, ALP in control group showed significant decrease in comparison with sham. That in WGY-treated was decreased in comparison with control. 3. Trabecular bone area as well as trabecular thickness in control group showed significant decrease in comparison with sham. Those in WGY-treated showed significant increase in comparison with control. 4. Osteoclast number and oseoblast surface in control group showed significant increase in comparison with sham. Those in WGY-treated showed significant decrease in comparison with control. Conclusion : WGY has shown to be capable of preventing and curing osteoporosis caused by old-aged and postmenopause.

본 연구의 목적은 요통으로 요부에 이상을 호소하는 중년여성에게 마사지를 실시하여 요부 유연성의 변화를 분석함으로써 요부 유연성에 미치는 영향을 규명하고, 향 후 요통연구에 필요한 기초자료로 제공되어 요통예방 및 완화에 도움을 주고자하는데 있다. 본 연구의 대상자는 서울시에 거주하고 있는 사람 중에서 요부에 통증이 있거나 불편하다라고 호소하는 여자 40명을 문진법으로 선정하였으며, 실험을 실시하는 동안 성실하게 참가한 실험군 15명과 대조군 15명을 선정하여 실시하였다. 이와 같은 절차를 통하여 도출한 결론은 다음과 같다. 첫째: 대조군과 실험군에 있어서 윗몸 앞으로 굽히기는 대조군은 통계학적으로 유의한 변화가 없었으나, 실험군은 통계학적으로 유의한 변화를 나타냈다. (P<0.05) 둘째: 대조군과 실험군에 있어서 윗몸 뒤로 젖히기는 대조군은 통계학적으로 유의한 변화가 없었으나, 실험군은 통계학적으로 유의한 변화를 나타냈다. (P<0.05) 셋째: 대조군과 실험군에 있어서 하지 들어올리기는 대조군은 통계학적으로 유의한 변화가 없었으나, 실험군은 통계학적으로 유의한 변화를 나타냈다. (P<0.05) 넷째: 대조군과 실험군에 있어서 윗몸 일으켜 정지시간에는 대조군은 통계학적으로 유의한 변화가 없었으나, 실험군은 통계학적으로 유의한 변화를 나타냈다. (P<0.05).

Objectives : The present study has been undertaken to investigate the effects of Cervi Cornu on treatment of osteoporosis in ovariectomized rats. Method : In this experiment, the rats were ovariectomized. Rats were administered by Cervi Cornu. The levels of bone mineral density, osteocalcin, ALP, calcium, phosphorus in serum, calcium, phosphorus, deoxypyridinoline in urine, ash weight of bone, body weight and uterus weight were measured. Results : 1. The levels of fibula-tibial bone mineral density were significantly increased in comparison with OVX group at 8 weeks in Cervi Cornu group. 2. The levels of serum osteocalcin showed significant decrease in comparison with OVX group at 4 weeks in Cervi Cornu group. The levels of serum ALP and phosphorus showed significant decrease in comparison with OVX group at 4, 8 weeks in Cervi Cornu group group. The levels of serum calcium showed significant increase in comparison with OVX group at 4, 8 weeks in Cervi Cornu group. 3. The levels of urine calcium, phosphorus and deoxypyridinoline showed significant decrease in comparison with OVX group in Cervi Cornu group. 4. The levels of fibula-tibial ash weight showed significant increase in comparison with OVX group in Cervi Cornu group. 5. The levels of body weight were significantly decreased in comparison with OVX group at 4, 8 weeks in Cervi Cornu group. 6. The levels of uterus weight were significantly increased in comparison with OVX group in Cervi Cornu group. Conclusion : Reviewing these experimetal results, it appeared that Cervi Cornu had efficacy on treatment of osteoporosis.

본 연구는 사회비교와 행복의 관계에 미치는 문화적 자기관의 영향을 살펴보기 위해 수행되었다. 사회비교와 행복은 부적관계에 있다고 알려져 있지만 사회비교의 결과는 비교 당사자의 자기인식과 비교동기에 따라 달라진다는 견해 역시 존재한다. 본 연구는 문화적 자기관이 사회비교와 행복에 미치는 영향을 알아보고자 전국 5대 권역(수도권, 강원, 충청, 전라, 경상)에서 표집한 권역 당 4개 연령대(30대, 40대, 50대, 60대) 각 100명씩, 총 2,000명을 대상으로 문화적 자기관(상호협조적 자기, 주체성-대상성 자기), 사회비교경향, 주관적 안녕감 및 심리적 안녕감을 조사하였다. 연구의 결과를 요약하면, 첫째, 상호협조적 자기는 사회비교와 정적상관을, 행복과는 부적상관을 보였고, 둘째, 상호협조적 자기가 높은 사람들은 사회비교를 많이 할수록 주관적 안녕감이 낮았지만, 낮은 사람들은 사회비교가 행복에 영향을 끼치지 않았다. 셋째, 대상성 자기가 높은 사람들은 사회비교를 많이 할수록 행복이 낮았지만, 주체성 자기가 높은 사람들은 사회비교가 행복에 영향을 미치지 않았다. 이를 바탕으로 사회비교의 결과에 영향을 미치는 자기관의 성격과 행복의 문화적 의미 등에 대해 논의하였다.
