Background: The greatest threats to the lives of cancer patients consist of both complications due to metastasis and the recurrence of original cancer. However, the existing forms of chemotherapy do not prevent these adverse events adequately because they suppress the patients' immune systems. A new methodology is required. Aim: To provide further validation for cancer immunotherapy (involving the use of traditional oriental herbal medicine). Method: Related articles, in both Korean and English were reviewed. Results: Cancer immunotherapy involving the use of traditional oriental herbal medicine can create inhospitable conditions for cancer cells and strengthen patients' immunological functioning. These effects are a demonstration of the principles of "strengthening healthy qi (扶正)" and "eliminating pathogens (祛邪)". As a result, immunotherapy protects against metastasis and original cancer recurrence by preventing the growth of cancer cells. This is very similar to the concept of a cancer dormancy therapy. Conclusion: It is strongly urged by the authors that more advanced studies be carried out on this promising therapy in the future in order to improve patients' quality of life and increase their survival time.

The photoelastic model material with shape memory effect and the molding processes for the material are developed in this research. The matrix and fiber of the photoelastic model material developed in this research are epoxy resin (Araldite to hardner 10 to 3 (weight ratio)) and wire of $Ti_50-Ni_50$ shape memory alloy, respectively. It is called Ti50-Ni50 Shape Memory Alloy Fiber Epoxy Composite $(Ti_50-Ni_50SMA-FEC).$ Ti50-Ni50 SMA-FEC is satisfied with the requirements of the photoelastic model material and can be used as a photoelastic model material. The maximum recovering strain of $Ti_50-Ni_50$SMA-FEC is occurred at $80^{\circ}C$ in any prestrain of $Ti_50-Ni_50$ shape memory alloy fiber and in any fiber volume ratio. Recovering strain(force) is increased with the increment of the prestrain and the fiber volume ratio. The best prestrain of $Ti_50-Ni_50$SMA-FEC is 5% for the recovering force among 1%, 3%, 5%.

The most effective material in the shape memory alloy(SMA) is the TiNi alloy, because its shape recovery characteristics are very excellent. We molded the composite material with shape memory function. The fiber of it is $Ti_{50}-Ni_{50}$ shape memory alloy and matrix of it is epoxy resin(Araldite B41, Hardner HT903. Ciba Geigy), its adhesive and optical sensitivity are very excellent. It was assured that the composite material could be used as model material of photoelastic experiment for intelligent materials or structures. In this research, the composite material with shape memory function is used as model material of photoelastic experiment. Photoelastic experimental hybrid method is developed in this research, it is assured that it is useful on the obtaining stress intensity factor and the separation of stress components from only isochromatic data. The measuring method of stress intensity factor of intelligent material by photoelastic experiment is introduced. In the mode I state, we can know that stress intensity factors are decreased more than 50% of stress intensity factor of room temperature when temperature of fiber is greater than 4$0^{\circ}C$, prestrain greater than 5% and fiber volume ratio greater than 0.42% and that stress intensity factors are decreased by 100% when fiber volume ratio is greater than 0.84%, prestrain greater than 5% and temperature greater than 60 $^{\circ}C$.

In this paper, single fiber pull-out test is used to measure the interfacial bonding shear strength of $Ti_{50}-Ni_{50}$ shape memory alloy composite with temperature. Fiber and matrix of $Ti_{50}-Ni_{50}$ shape memory alloy composite are respectively $Ti_{50}-Ni_{50}$ shape memory alloy and epoxy resin. To strengthen the interfacial bonding shear stress, various surface treatments are used. They are the hand-sanded surface treatment, the acid etched surface treatment and the silane coupled surface treatment etc.. The interfacial bonding shear strength of surface treated shape memory alloy fiber is greater than that of surface untreated shape memory alloy fiber by from 10% to 16%. It is assured that the hand-sanded surface treatment and the acid etched surface treatment are the best way to strengthen the interfacial bonding shear strength of $Ti_{50}-Ni_{50}$ shape memory composite. The best treatment condition of surface is 10% HNO$_3$ solution in the etching method to strengthen the interfacial bonding shear strength of $Ti_{50}-Ni_{50}$ shape memory alloy composite.

칼빈의 율법의 제3용법과 이자금지법 해석 ; 구약 율법의 적용 사례 연구

이효재 ( Hyo Jae Lee ) 한국개혁신학회 2013 한국개혁신학 Vol.41 No.-

칼빈은 중세 스콜라주의자들이나 루터와 같은 이전 신학자들과 달리 상업적인 이자를 허용한 첫 번째 기독교 신학자로서 서구 사회에 적잖은 변화를 가져왔다. 최근 연구들은 그가 왜 이자를 허용했는지를 분석하고 있는데, 필자는 구약 율법에 대한 칼빈 자신의 이해에 근거한 성경 해석의 결과였다는 점을 새롭게 제시한다. 칼빈은 자신의 ‘율법의 제3용법’ 개념으로 이자금지법을 해석하면서 율법의 궁극적 목표인 사랑을 실천할 수 있다면 이자를 금지한 율법 규정을 문자적으로 지키지 않아도 된다고 주장하며 문자적 준수보다 율법에 담긴 하나님의 뜻을 성도들의 일상에 적용하는 것이 율법의 진정한 정신이라고 강조했다. 칼빈은 자신이 살던 16세기 제네바에서 이자를 주고받는 경제 활동을 통해 산업을 발전시켜 긴박한 가난 문제를 해결할 수 있다면, 이것이 오히려 이자금지법에 담긴 하나님의 의도를 더 정확하게 구현하는 것이라고 보았다. 하나님은 이 법을 통해 가난한 자를 보호하기 원했기 때문이다. 다만 그는 가난한 자들의 생계를 위한 대부에는 이자를 부과해서는 안 된다는 단서 조항을 붙였다. 이와 같은 칼빈의 율법 해석을 통해서 우리는 구약의 율법이 오늘 우리의 일상생활과 무관한 것이 아니라 여전히 하나님의 뜻을 전달하고 있음을 발견한다. 율법이 주어졌던 구약시대와 많이 달라진 오늘날에 율법을 적용하기 위해서는 율법의 본래 정신을 현실에 맞도록 창조적이고 탄력적으로 적용해야 함을 칼빈을 통해 배울 수 있다. This article aims to provide a new way to understand the theological foundation of John Calvin`s interpretation of the usury laws in the Mosaic Law. His interpretation of the usury laws was radically different from that of Scholastics and even other Reformers of his days. His challenge against the church tradition that read the usury laws literally provided a significant turning-point to the development of the capitalism of Western Europe. Scholars have researched to find the reason why he was different from others on this issue. Recent studies focused on the idea of equity as his ethical principle in his understanding of usury. Not satisfied with this result, I tried to find a deeper reason and found the more basic theological ground for his revolutionary idea on usury: his idea of the third use of the Law. This idea means that Mosaic laws, though given for the recognition of our sinfulness, can be used as a moral guide for believers. Calvin argues that the final goal of the Old Testament laws is to love God and neighbor. This idea made him believe that the usury laws could play a positive role in the life of believers. For Calvin, if usury could be used to practice the love of the poor in the 16th century context which was far different from that of the Mosaic Law, this usury should be permitted. Using this interpretive method, Calvin concludes that the usury laws do not mean unserved prohibition but the practice of love, especially for the poor. For this reason, Calvin permitted some kinds of usury practiced in marketplaces, because he experienced positive roles of usury that helped the poor to make profit and relieve from poverty. But he strictly prohibited usury charged to the lending for the life of the poor. The idea of the third use of the Law opened Calvin`s eyes to see the other aspect of usury that was condemned by the Roman Catholic church. This argument will help Calvin researchers to know a reason why Calvin interpreted the usury laws of the Old Testament in such a revolutionary way.

현대 기독교철학의 동향 깔뱅의 돈 이해에 대한 비판적 고찰 -짐멜의 문화이론 관점에서-

이효재 ( Hyo Jae Lee ) 한국기독교철학회 2011 기독교철학 Vol.13 No.-

Reformer Jean Calvin, in the middle of a changing period from the medieval to the modern times, conditionally permitted usury (interest) which was strictly prevented by the medieval church through his own new biblical interpretation. His theological argument about usury was based upon his revolutionary understanding of money. The medieval church oppressed making profit by money and controlled the objective culture of money not to destroy the religious subjective culture which was built by the church for a long time. Medieval church, however, could not resist any more the apparent phenomenon of the development of capitalism. Money was expanding the objective culture created by its inner logic at that time. Calvin adopted this phenomenon rather than resisted and used usury system to solve the rapidly increasing problem of poverty of the city of Geneva. His idea was to permit receiving usury for capitalists to induce their money into the new industry and business of the poor. His idea was successful. Nevertheless, Calvin did not permit charging usury on the lending for the poor. From the perspective of Georg Simmel`s theory of culture, Calvin`s theological and pastoral stance was to balance between the objective and the subjective culture. This balance was broken after Calvin. The objective culture of money slowly took over the subjective culture for which the medieval church tried to keep for hundreds years through preaching and teaching at the church. Max Weber found this tragic cultural phenomenon, the victory of the objective culture of money, from the later Puritans. Though not intended, Calvin opened the way for the objective culture of money to prevail the present economic world which suffers from consumerism.

농산물의 수입개방으로 질이 낮은 수입 농산물이 국산으로 둔갑하여 소비자의 신뢰가 낮아지고 있으며, 국산 농산물의 가격 경쟁력이 지속적으로 하락하고 있는 실정이다. 이러한 위기 상황에서 국산 농산물의 원산지에 대한 신뢰도를 높이고 아시아의 주식이지만 여전히 기술이 낙후되어 있는 미곡 산업에서도 이러한 첨단 기술을 적용하고자 하는 노력이 진행중이나 아직도 미흡한 실정이다. 나아가, 기존의 농산물 생산이력시스템은 기초적인 이력정보만 제공하고 있으며, 미곡종합처리장의 경우에 경험적인 수확시기 결정으로 인해 일시에 수확이 몰리는 홍수반입이 발생하여 미곡의 품질 손상이 빈번히 발생하기도 한다. 본 논문에서는 스마트 기기와 GIS/LBS, RFID 등의 유비쿼터스 기술을 적용하여 유비쿼터스 벼 생산 및 반입관리 시스템을 개발하였다. 기존에 수기로 작성하던 농가 및 농지 정보를 스마트 기기로 입력하고, 재배단계에서의 품질 모니터링을 제공하며, 수집된 생산, 재배, 품질정보를 스마트기기를 통하여 제공한다. 데이터베이스를 기반으로 하여 품질에 따른 반입시기를 결정하는 과학적인 반입체계를 구축하고, 농가와 유통업자, 소비자간의 신뢰도를 높이고자 한다. In this paper, an rice intake management system based on ubiquitous computing technology is introduced for rice processing complex (RPC). This system plays an important role in the quality management for rough rices in that the system provides timely and useful information of rice cultivation. The intake management system is developed by utilizing widespread ubiquitous technologies, such as smartphones, GIS and LBS, for the purpose of controling the harvest time and monitoring the quality of paddy. The information for rice production, cultivation and quality management is transmitted and stored in a centralized database via mobile networks, On the basis of these information, the harvest schedule is determined and notified to farmers though smart devices. Hence, the proposed system can help to establish trust among farmers, operators and consumers by providing systematic information based on ubiquitous computing technology.
