This study was done to compile 104 experimental theses which are related to the antitumor and immuno-activating therapies between February 1990 through February 2002. Master's and doctoral theses were dassified by schools, degrees, materials, effects, experimental methods of antitumor and immunoactivity, and results. The following results were obtained from this study : 1. Classifying the theses by the school, 34.6% were presented by Daejeon University, 29.8% by Kyung-hee University and 11.5% by Won-kwang University. Of all theses, 51.0% were aimed for the doctoral degree and 43.3% were for the master's degree. All of three universities have their own cancer centers. 2. Classifying the theses by herb materials, complex prescription accounted for 60.3%, single herb accounted for 24.8% and herbal acupuncture accounted for 14.2%. Considering the key principles of the traditional medicine, complex prescription was much more thoroughly studied than single herb prescription. The results showed that the complex prescription had both antitumor activity and immuno-activating activity, which might reflects on multi-activation mechanisms by complex components. 3. Classifying the theses by the efficacy of herbs examined, in single herb, invigorating spleen and supplementing was 35.5%, expelling toxin and cooling was 29.0%, activating blood flow and removing blood stasis was 12.9%. In herbal acupuncture, invigorating spleen and supplementing was 52.9%, expelling toxin and cooling was 29.4%. In complex prescription, pathogen-free status was 41.9%, strengthening healthy qi to eliminate pathogen was 35.5%, strengthening healthy qi was 22.6%. It is presumed that the antitumor and immunoactivating therapy based on syndrome differentiation is the best way to develop oriental oncology. 4. Classifying the theses by antitumor experiments, cytotoxic effect was 48.1 %, survival time was 48.1 % and change of tumor size was 42.3%. Survival rate was not necessarily correlated with cytotoxicity. These data reflect the characteristic, wholistic nature of the oriental medicine which is based on BRM (biological response modifier). 5. Classifying the theses by immunoactivating experiments, hemolysin titer was 51.0%, hemagglutinin titer was 46.2% and NK cell's activity was 44.2%. In the future studies, an effort to elucidate specific molecular and cellular mechanisms of cytokine production in the body would be crucial. 6. Classifying the theses according to the data in terms of antitumor activity, 50% was evaluated good, 24.0% was excellent, and 15.5% have no effect. In an evaluation of immuno-activating activity, 35.9% was excellent and 18.0% showed a little effect. The index point, as described here, may helps to use experimental data for clinical trials. Changes in index points by varying dosage implicate the importance of oriental medical theory for prescription. 7. In 167 materials, IIP (immunoactivating index point, mean : 3.12±0.07) was significantly higher than AIP(antitumor index point, mean : 2.83±0.07). These data demonstrate that the effect of herb medicine on tumor activity depends more on immunoactivating activity than antitumor activity. This further implies that the development of herbal antitumor drugs must be preceded by the mechanistic understanding of immunoactivating effect. 8. After medline-searching tumor and herb-related articles from NCBI web site, we conclude that most of the studies are primarily focused on biomolecular mechanisms and/or pathways. Henceforth, we need to define the biomolecular mechanisms and/or pathways affected by herbs or complicated prescriptions. 9. Therefore, the most important point of oriental medical oncology is to conned between experimental results and clinical trials. For the public application of herbal therapy to cancer, it is critical to present the data to mass media. 10. To develop the relationship of experimental results and clinical trials, university's cancer clinic must have a long-range plan related to the university laboratories and, at the same time, a regular consortium for this relationship is imperative. 11. After all these efforts, a new type herbal medicine for cancer therapy which is to take care of the long-term administering and safety problem must be developed. Then, it would be expected that anti-tumor herbal acupuncture can improve clinical symptoms and quality of life (QOL) for cancer patients. 12. Finally, oriental medical cancer center must be constructed in NCC (National Cancer Center) or government agency for the development of oriental medical oncology which has international competitive power.

본 연구는 최근 지속적으로 주목 받고 있는 사물인터넷 중 공공 부문에 대한 핵심적인 기술수용요인을 찾고자 한다. 기존연구에서는 사물인터넷은 디지털 시스템을 작동하기 위해 인간의 개입이 거의 관여하지 않는 반면 사람에게 전달하는 많은 산출물(정보)을 제공한다는 점에서 전통적으로 사용해 온 디지털 시스템과 매우 다르다고 정의하고 있다. 일반적으로 전통적인 디지털 시스템은 사람이 주체이지만, 사물인터넷은 디지털 시스템을 작동하기 위하여 인간이 객체가 되는 것이다. 다시 말하면, 사물과 사물간의 네트워크만을 가지고도 디지털 시스템을 작동하게 할 수 있다는 것을 말한다. 결국 이러한 장점들이 그 기능을 발휘하여 공공부문에서 사물인터넷을 통하여 사회적 비용을 상당히 줄이는 성과도 최근 보고된바 있다. 그러나 이러한 많은 사물인터넷의 강점에도 불구하고 사물인터넷에 대한 사용자의 기술수용요인을 구체적으로 밝힌 연구는 거의 없다. 이는 사물인터넷의 개발 시에 목적성에만 부합하면 된다는 개념을 말하고 있다. 만약 이러한 목적 부합적인 개발에만 집중하게 되면, 사용자가 어떤 기술을 사용하고 있는지 구체적인 이유에 대하여 간과하게 되어 향후 사용자들은 지속적 사용을 거부할 수 있다는 것을 의미한다. 이에, 본 연구에서는 1986년부터 2003년까지 기술수용모델에 대한 도입, 확인, 확장, 정교화의 4단계 과정을 거친 검증모형을 활용하여 공공부문에 사물인터넷 개발 시에 반드시 반영해야 할 요인들을 사용자들로부터 찾고자 한다. 본 연구결과를 요약하면, 공공사물인터넷의 결과에 대한 설명력이 가장 중요한 요인으로 유일하게 지각된 사회적 유용성과 사용용이성에 영향을 주는 것으로 나타났다. 결국 사용자에게 사용에 대한 긍정적 태도를 확보한 경우 지속사용의도를 긍정적 영향을 미치는 것을 알 수 있다. 본 연구의 시사점을 정리하면, 공공사물인터넷 서비스가 제공될 때는 결과에 대하여 사용자가 쉽게 이해할 수 있으며, 사람과 사물이 그리고 사람 간에 그 결과에 대하여 상호소통이 가능해야 함을 의미한다. 이는 현재 제공 되고 있는 공공 사물인터넷에 결과에 대한 이해를 위해 사용자 노력이 많이 필요하다는 것을 말한다.

사진과 사진행위에 대한 부르디외의 사회학적인 분석은 $\ll$중간예술$\gg$과 $\ll$구별짓기$\gg$를 통해 발표되었다. 여러 문화적 산물들 중 사진은 사회과학에서 소홀히 다루어져 왔기 때문에 사진에 대한 부르디외의 연구는 주목할 만한 가치가 있다. 특히 $\ll$중간예술$\gg$은 거의 모든 사진 장르들을 다루면서 사회적 계급들이 사진에 대해 적용하는 규범 체계들, 사진행위의 유형들, 여러 분야의 전문 사진사들이 자신들의 직업에 대해 가지고 있는 생각들과 그들이 참조하는 미학들을 분석하고 있고 최종적으로는 그러한 분석을 바탕으로 사진에 대한 정신분석학적 분석도 시도함으로써 사진과 사진행위에 대해 체계적이고 명료하게 인식할 수 있는 기회를 제공했다는 점에서 대단히 의미가 있는 작업이라 할 수 있다. 그러나 주요 분석 대상인 사진이 급속한 기술적 변화를 겪고 있는 매체이며 경제적이고 문화적인 요인들의 변화에 따른 위상의 변화를 보이고 있는 매체라는 점에서 부르디외의 분석은 오늘날 몇 가지 수정되어야 할 부분들을 가지게 되었다. 우선 부르디외가 강조한 사진의 사회적 기능이 무척 약화되었다. 반면에 사진의 예술적 지위는 대단히 상승했다. 이에 따라, 사진과 사진행위를 둘러싼 사회적 계급간의 관계들도 변했을 것이라 가정할 수 있다. 물론 이러한 계급간의 관계의 변화는 이후의 연구들을 통해 입증되어야 할 것이지만 적어도 오늘날, 부르디외가 연구를 진행했던 시기처럼 단호하게 사진을 중간예술이라고 규정하는 것은 무리가 있어 보인다. 따라서 부르디외의 작업을 현재의 상황에 무비판적으로 적용하기 전에 그 작업을 1960년대의 프랑스라는 사회적이고 역사적인 특수성 안에 위치시키고 사회학, 심리학, 미학, 기호학이 충돌하는 지식의 장 속에서 부르디외의 역할을 살펴봄으로써 그의 연구가 갖는 특성과 한계에 대해 명확히 인식할 필요가 있다.

Nowerdays, the increase of traffic accidents and old age population make the Femoral Neck Fracture(FNF) patients increase. By the improvement of education and standard of living the patients demand better medical service than before. This study is designed to give practical help for the FNF patients by observing their hospital life and establish practical nursing strategies for the FNF patients. For these purposes the Ethnographic Participant Observation was adopted. By this study is focused on the hospital life patient's view. For this end, the field study adopted orthopedic ward in the C University Hospital with 400 beds in Seoul. The object patients of the study were twelve patients. The patients experienced five stages : Embarrassment, Conflict, Stability, Independent, and Extension Stage. The findings and prepared nursing strategies are stated as follows. First, in the Embarrassment Stage they suffered embarrassment, anxiety, pain, they could not do ordinary things. The patients who accidental fractures had anxiety from unfamiliar tests and from hospitalization itself. They lamented that they could not ordinary things, and do nothing but obeying the hospital, and endure the pain. They recognized the changed environment and resigned themselves to life in the ward. In this stage, full openness by the nurses is needed. Second, the attribute of the Conflict Stage were conflict, fear, curiosity, belief, reflection. When they sign the consentment form, they experience conflicts about the possibility of complication, fear of recovery from anesthesia, curiosity about the operation procedure, post - operation state, reflection on their past life, and promise to care for their family members after discharge and keep their religious life faithfully. And they accepted the operation depending on God, believing in modern medicine, and the surgeon. Asking for their changed informations, they expected positive results from the operation. In this stage, an empathic attitude by the nurses is needed. Third, the attribute of the Stability Stage were relief, gratitude, difficulty with excretion, and pain. When they awoke from anesthesia, they felt relief because of a the end of the operation, but they experienced extreme pain, difficulty of excretion in bed. They accepted the changed environment and expected recovery. In this stage, support by the nurses is needed. Fourth, the attributes of the Independence Stage were freedom, exercise, nurturing, anxiety, and discomfort. When they ambulated and exercised, they experienced freedom. They showed exhibited weakness of the digestive organs and discomfort hospital's space, structure, and facilities, the delay of medical certificate issue the lack of prompt response by the medical agents. They ate nurturious food and felt anxiety on the end of hospital life and returning to their ordinary life. They showed the independence of overcoming their environment by increasing exercise and expected their discharges. In this stage, respect by the nurses is needed for the patients to, overcome their environment and prepare for their independence. Fifth, the attributes of the Extension Stage were pessimism, isolation, dissatisfaction, and pain. Accompanied injury and old age made their ward life extend to over seven weeks. They exhibited weariness, melancholy, skeptisis, general pessimistic feeling, and desperation caused by their isolated life. They experienced the digestive discomfort caused by the prolonged medication and psycological pain caused by long-time hospitalization. As a, result, their dissatisfaction on the human, physical, and systematic environments had been increased. They acquired critical power and sought for something to do spending their time. They expected vaguely about the returning of their ordinary life. In this stage, counseling is needed by the nurse to overcome positively their psychological, social, and physical problems. The process of the FNF patient's ward life starts from the dependent state, when they are hospitalized, and gradually progresses to self-fulfillment in order to keep independent life. As a result, the FNF patients showed "Response in Challenge" or "Adaptation in Conflict" through their experiences of social, physical, and psychological difficulties.

The purposes of this study were to determine the relevant nursing needs of patients following discharge; to identify the degree of their nursing needs; to identify types and status of discharge order and information given to patients; and to determine their specific nursing needs according to their diagnosis. In addition, opinions toward home care services provided by hospitals or by public health nurses and appointment plans with their physicians were also asked in order to determine the necessity of follow-up care for the patient after discharge. Nine hundred and eighty eight subjects were collected among patients being discharged from one national university hospital and four city hospitals. Data were collected from June,1979 to December,1979 using questionnaires and interviews. On the bases of these data the following findings were observed; 1) Almost 40 percents of total subjects discharged from the hospital with some or great degree of nursing needs in general. The most problematic nursing needs were needs for comfort which include needs for releaving pain, for sound sleep and rest, because these needs can only be met by professional help. More than 50% of total subjects have this problem. 2) Needs for mental health, general metabolism, general hygiene and activities and safety were observed in more than 20 percent of subjects. 3) Discharge orders on diet and oral medication were recorded in patients' charts in 70% of all cases. However, more than fifty percents of patients have not been told these information from doctors or nurses. Even though some of them might have had appointment plans with their physicians, they would not keep the appointments unless they completely understood the necessity of the follow-up care. If they have not had any appointment or would not visit the out-patient clinic, there is no method of caring them and prerenting funther discomfort or complications. Even in injection, ski care, dressing and bath, only one thirds of the subjects having recorded discharge orders understood what they need after discharge. The rest of cases have not known what to do for their further care. 4) More than 80 percents and 70 percents of total subjects agreed to a system of home care services provided by hospitals or public health nurses respectively. That is, regardless of sources of medical expenses, most of patients wanted to be taken care of at home following discharge. 5) While more than half of the patients having benefit of medical insurance or paying fully by themselves had appointment plans with their physicians, only one thirds of the patients fully or partially paid by government had appointment plans with their physicians. These results ex-plain that the appointment plan is directly associated with their economic power. This indicates that the home care services are more needed to the people with lower economical status. 6) Those who have been in the hospital more than 24 days wanted !o have home care services more than those who had less hospital days. They also had more appointment plans than other groups. 7) More than 70 percents of the subjects who had been in a university hospital and approximately 30 percents of the subjects in the city hospitals had appointment plans with their physicians. 8) Those who had the cerebrovascular disease, cancer or hypertension demanded more nursing needs such as needs for comfort, for general metabolism and for mental health. 9) Factors which were associated with the degree of patients' nursing needs were age, duration of hospitalization, opinion toward home care services given by public health nurses, hospital appointments and types of hospital. That is, the older they were and the longer the periods of hospitalization were, the higher were their nursing needs. The more they had nursing needs, the more they wanted to have nursing services and had appointment plans. It can be concluded that there is a great demand for a positive and systematic home care services to the people who have been discharged from hospitals following critical care. This program is definitely demanded for the low income groups of people with less education with the financial assistance of the government or other funding agencies.

기후변화 및 교토의정서상의 온실가스 의무감축요구에 대응하기 위하여 발전소 및 제철소 등 대규모 발생원에서부터 포집한 $CO_2$를 파이프라인이나 선박 등을 통해 수송하고, 이를 해저 지질구조내 대규모로 수백-수천년 이상 장기간 저장 및 관리하는 $CO_2$ 해양지중저장기술이 국내외적으로 주목 받고 있다. $CO_2$ 해양지중저장 처리 시스템 설계를 수행하는데 있어 전산모사를 통한 공정 설계는 필수적이다. 즉, 수치 모델링을 통하여 $CO_2$ 해양지중저장 처리에 필요한 일련의 공정을 열역학 상태방정식 등을 이용하여 모사하는 것이다. 본 논문에서는 $CO_2$ 해양지중저장 처리를 위한 공정 설계에 사용되는 열역학 상태방정식들을 비교 분석하였다. 또한, 상태방정식 계산결과의 정확성을 평가하기 위하여 실험으로부터 구해진 데이터와 비교를 수행하였다. 이상기체 상태방정식과 SRK식은 $29.85^{\circ}C$, 60 bar 이상에서 밀도를 전혀 예측하지 못하였으며, 고온 고압의 초임계 상태에서 100% 내외의 오차를 보였다. BWRS 식은 임계온도 근처인 $29.55^{\circ}C$, 임계압력 근처인 $60{\sim}80\;bar$ 사이의 영역에서 실험값을 전혀 예측하지 못하고 최대 100%의 차이를 보였다. $CO_2$ 해양지중저장 처리의 저장지 조건인 온도 $31.1^{\circ}C$ 이상, 압력 73.9 bar 이상의 초임계 상태에서 PR 식과 PRBM 식은 실험값을 비교적 잘 예측하였다. 따라서 $CO_2$ 해양지중저장처리 공정 중 고온, 고압 영역에서는 상기 상태방정식을 이용한 공정 설계가 유용하다고 판단된다.

Recently the abusive calls on on-demand bonds have been a critical issue among many engineering and construction companies in Korea. On-demand bond is referred to as an independent guarantee in the sense that the guarantee is independent from its underlying contract although it was issued based on such underlying contract. For this reason, the issuing bank is not required to and/or entitled to look into whether there really is a breach of underlying contract in relation to the call on demand-bonds. Due to this kind of principle of independence, the applicant has to run the risk of the on demand bond being called by the beneficiary without due grounds. Only where the call proves to be fraudulent or abusive in a very clear way, the issuing bank would not be obligated to pay the bond proceeds for the call on on-demand bonds. In order to prevent the issuing bank from paying the proceeds under the on-demand bond, the applicant usually files with its competent court an application for injunction prohibiting the beneficiary from calling against the issuing bank. However, it is in practice difficult for the applicant to prove the beneficiary's call on the bond to be fraudulent since the courts in almost all the jurisdictions of advanced countries require very strict and objective evidences such as the documents which were signed by the owner (beneficiary) or any other third party like the engineer. There is another way of preventing the beneficiary from calling on the bond, which is often utilized especially in the United Kingdom or Western European countries such as Germany. Based upon the underlying contract, the contractor which is at the same time the applicant of on-demand bond requests the court to order the owner (the beneficiary) not to call on the bond. In this case, there apparently seems to be no reason why the court should apply the strict fraud rule to determine whether to grant an injunction in that the underlying legal relationship was created based on a construction contract rather than a bond. However, in most jurisdictions except for United Kingdom and Singapore, the court also applies the strict fraud rule on the ground that the parties promised to make the on-demand bond issued under the construction contract. This kind of injunction is highly unlikely to be utilized on the international level because it is very difficult in normal situations to establish the international jurisdiction towards the beneficiary which will be usually located outside the jurisdiction of the relevant court. This kind of injunction ordering the owner not to call on the bond can be rendered by the arbitrator as well even though the arbitrator has no coercive power for the owner to follow it. Normally there would be no arbitral tribunal existing at the time of the bond being called. In this case, the emergency arbitrator which most of the international arbitration rules such as ICC, LCIA and SIAC, etc. adopt can be utilized. Finally, the contractor can block the issuing bank from paying the bond proceeds by way of a provisional attachment in case where it also has rights to claim some unpaid interim payments or damages. This is the preservative measure under civil law system, which the lawyers from common law system are not familiar with. As explained in this article, it is very difficult to block the issuing bank from paying in response to the bond call by the beneficiary even if the call has no valid ground under the underlying construction contract. Therefore, it is necessary for the applicants who are normally engineering and construction companies to be prudent to make on-demand bonds issued. They need to take into account the creditability of the project owner as well as trustworthiness of the judiciary system of the country where the owner is domiciled.

Recently, the CO2 emission and energy consumption have become critical global issues to decide the future of nations. Especially, the spread of IT products and the increased use of internet and web applications result in the energy consumption and CO2 emission of IT industry though information technologies drive global economic growth. EU, the United States, Japan and other developed countries are using IT related environmental regulations such as WEEE(Waste Electrical and Electronic Equipment), RoHS(Restriction of the use of Certain Hazardous Substance), REACH(Registration, Evaluation, Authorization and Restriction of CHemicals) and EuP(Energy using Product), and have established systematic green business/IT strategies to enhance the competitiveness of IT industry. For example, the Japan government proposed the "Green IT initiative" for being compatible with economic growth and environmental protection. Not only energy saving technologies but energy saving systems have been developed for accomplishing sustainable development. Korea's CO2 emission and energy consumption continuously have grown at comparatively high rates. They are related to its industrial structure depending on high energy-consuming industries such as iron and steel Industry, automotive industry, shipbuilding industry, semiconductor industry, and so on. In particular, export proportion of IT manufacturing is quite high in Korea. For example, the global market share of the semiconductor such as DRAM was about 80% in 2008. Accordingly, Korea needs to establish a systematic strategy to respond to the global environmental regulations and to maintain competitiveness in the IT industry. However, green competitiveness of Korea ranked 11th among 15 major countries and R&D budget for green technology is not large enough to develop energy-saving technologies for infrastructure and value chain of low-carbon society though that grows at high rates. Moreover, there are no concrete action plans in Korea. This research aims to deduce the priorities of the Korean green business/IT strategies to use multi attribute weighted average method. We selected a panel of 19 experts who work at the green business related firms such as HP, IBM, Fujitsu and so on, and selected six assessment indices such as the urgency of the technology development, the technology gap between Korea and the developed countries, the effect of import substitution, the spillover effect of technology, the market growth, and the export potential of the package or stand-alone products by existing literature review. We submitted questionnaires at approximately weekly intervals to them for priorities of the green business/IT strategies. The strategies broadly classify as follows. The first strategy which consists of the green business/IT policy and standardization, process and performance management and IT industry and legislative alignment relates to government's role in the green economy. The second strategy relates to IT to support environment sustainability such as the travel and ways of working management, printer output and recycling, intelligent building, printer rationalization and collaboration and connectivity. The last strategy relates to green IT systems, services and usage such as the data center consolidation and energy management, hardware recycle decommission, server and storage virtualization, device power management, and service supplier management. All the questionnaires were assessed via a five-point Likert scale ranging from "very little" to "very large." Our findings show that the IT to support environment sustainability is prior to the other strategies. In detail, the green business /IT policy and standardization is the most important in the government's role. The strategies of intelligent building and the travel and ways of working management are prior to the others for supporting environment sustainability.
