본 연구는 실크로드의 역사를 다시 조명하여 실크로드의 주역이었던 고조선의 아름다운 실크의 감성을 찾아보고 잘 알려지지 않은 우리의 역사를 알아보고자 한다. 연구 방법은 고서, 서적, 논문, 유적지 발굴 유물들을 분석하는 다양한 접근을 시도하였으며, 유물에 대한 자료는 다양한 서적과 논문 그리고 인터넷을 통해 관련 유물사진들을 수집한 2차적 자료를 분석하였다. 연구문제는 다음과 같다. 첫 번째, 고대 실크로드와 고대 동양에서 발견된 고조선의 경금의 실크 생산 환경을 조사한다. 두 번째, 고조선의 경금의 고도의 제작기술에 대해 조사한다. 본 연구 결과는 다음과 같다. BC 4500년 홍산문화의 동이족으로부터 발견된 옥으로 만든 누에를 통해 고조선의 실크 생산 시기를 추론할 수 있다. 신장자치구 누란, 아스타나, 니야 등에서 경금이 많이 출토되었으며 가장 오래된 경금은 기원전 11세기경으로 서 발해만 고조선의 수도 중 하나였던 조양에서 발굴된 것이다. 서양의 브로케이드 및 다마스크의 기원으로 보이는 경금은 고조선의 수평 사각직기인 제화루기로 고도의 제직기술의 발전된 직기를 통해서 생산되었다. 이와 같은 결과를 통해 고대 실크로드의 특징은 기원전 5-6세기경 발해만 유역의 고조선에서 생산한 경금 견직물이라고 추측할 수 있었다. 한나라의 사직기나 서아시아의 수직직기로 경금 제직이 불가능하며 고조선의 제화루직기과 함께 고도의 제직기술을 통해서만 경금이 탄생될 수 있었다. 이와 같은 연구결과를 토대로 고대의 실크에 관한 역사 연구를 이어나가기 위해 중요한 초석이 될 것이며, 앞으로 고대 실크에 관한 후속 연구에 필요한 기초 자료로 제공되기 바란다.

Phytochemical studies on the leaves of Ailanthus altissima (Simaroubaceae) have not been reported previously. Thus, the authors isolated and identified secondary metabolites from A. altissima. Dried and powdered leaves were extracted with 80% aqueous methanol, and the concentrated extract was successively partitioned with ethyl acetate, n-butanol, and water. Four flavonoids were isolated from the ethyl acetate fraction through repeated silica gel and octadecyl silica gel column chromatography. Spectroscopic data including NMR, MS, and IR allowed for identification of the chemical structures as quercetin (1), afzelin (2), quercitrin (3), and isoquercitrin (4). This is the first report of the isolation of these compounds from A. altissima. The four isolated flavonoids 1-4 as well as solvent fractions (ethyl acetate, n-butanol, and water), were evaluated for DPPH radical scavenging activity.

An experimental study was performed for the preparation of living skin-equivalent by the using collagen gel contraction with human fibroblasts as neodermls and cultured human keratinocytes as neoderm is . The results were as follows ; 1) The rate of collagen gel contraction was dependent on the number of fibroblasts into the lattice and collagen contraction was progressed according to the increment of the number of the cells. 2) The rate of collagen gel contraction was progressed according to the decrement of the contraction of the collagen. 3) The rate of gel contraction was progressed according to the increment of serum concentration in the fixed concentration of the fibroblasts and collagen. 4) The lattice contraction was decreased according to the increment of the population doublings of the fibroblasts. 5) Macroscopically, the artificial dermis was gray white in color and tissue-like consistency and elas- ticity. 6) Microscopically, three dimensionally contracted artificial dermis showed more dense fibroblasts and its newly formed collagen fibrils in the matrix than one dimensionally contracted one. 7) Finally prepared skin-equivalent showed good attachment of living stratified keratinocytes to the dermal equivalent microscopically. It has been proposed that newly formed skin-equivalent is suitable for the graft of extensively and deeply burned patients. Shortening of the manufacturing period of skin-equivalent and development of conservation technique as a readily usable state are to be solved for our ongoing works.

I examined throughout where Sa Gi Gang Boo Byung Hyung(邪氣藏府病形) was shown. It is shown in many books, such as Young Chu(靈樞), Kab Eul Kyung(甲乙經), Nan Kyung(難經), Yu Kyung(類經), etc. Sa Gi Gang Boo Byung Hyung got its name by how its contents pointed to the mechanism of getting harmed by Sa Gi(邪氣), and the forms of diseases which were led from five organs and six hollow viscera getting harmed by Sa Gi(邪氣). Sa Gi Gang Boo Byung Hyung is divided into three chapters which are divided altogether into nine sections. The first chapter is on the mechanism of Sa Gi(邪氣)' s harming the five organs and the six hollow viscera. Going into details, it discusses that Sa Gi has got two different ways which are divided into Yum Yang(陰陽) to harm the organs and the hollow viscera. Next, it discusses how faces can endure the cold that well. The second chapter is on the essences such as symptoms, face colors, shapes of pulse, and conditions on the interior part of the elbow. In the first section, it discusses how figures, colors and pulses relate together. In the second section, it discusses different diseases have different pulses and conditions on the interior part of the elbow. The third section is on forms of diseases in five organs and six hollow viscera. The third chapter is on acupuncture. The first section is about acupuncturing six channels. The second is about acupuncture points which is compared to the sea by its function. The third is about the forms of diseases with discussing symptoms and acupuncture points. The forth is about the essence of acupuncture. The ten different pulses of each five organs, and the masses of five organs in Nan Kyung(難經), and Jang Bu Mak Jin Beob(臟腑脈診法) in Eu Hak Yib Moon(醫學入門) are based on 'The six different pulses of each five organs' which is shown in the third section, second chapter. Besides, it plays an important role in study and it can play an important role as well in doctoring such as inspecting, taking pulses and so on. Thus, I found Sa Gi Gang Boo Byung Hyung worth while to study. But, Sa Gi Gang Boo Gyung Hyung was written in ancient letters and was omitted in many parts, which led successive doctors to write different explanatory notes. Thus, I researched the exact meaning through successive explanatory notes.

This study aimed was done to analyze recent trends in nursing research published in the Journal of Korean Academy of Nursing by focusing on the content of nursing interventions and their level of evidence. Methods: A total of 209 studies published between 2007 and 2008 were reviewed using analysis criteria developed by the researchers. Results: The number of quantitative studies was greater than that of qualitative studies. There was a slight increase in the number of qualitative studies and studies including elderly populations, which reflects the recent population trend in Korea. More randomized controlled trials with a low risk of bias were needed to support more evidence-based nursing practice. Concerning the low rate of ethical consideration, stricter application of research ethics needs to be encouraged. Conclusion: The findings of this study suggest the recent trends in nursing research and the direction of nursing research and review in the Journal.

Objectives The present study examined the recent domestic and international trends of non-surgical treatment of lumbar spinal stenosis (LSS). Methods The studies on non-surgical treatment of LSS were investigated via searching Korean web databases and PubMed. As a result, 39 studies were analyzed according to the authors, the types of study, the relationship to surgical treatment and the method of treatment. Results The first authors' occupations were identified as 17 doctors, 12 Korean medicine doctors, six physiotherapists, three chiropractic doctors and one doctor of science. The most common type of study in Korea was the case report and most of the studies were retrospective. Overseas, there were many prospective or experimental studies including randomized controlled trials (RCT). In Korea, non-surgical treatment was performed independently of surgical treatment in most cases. Among non-surgical treatments, the most researched treatment was traditional Korean medicine (TKM), followed by injection therapy, exercise therapy, and physical therapy. Conclusions Through this review, we can determine the effectiveness of TKM and its research direction. TKM should be studied experimentally including RCT and it should be conducted not only on acupuncture, but also on other treatment methods such as acupotomy, chuna, and herbal medicine. It is also necessary to conduct studies on TKM before and after surgery to compare the effects of surgery and TKM together, as well the effects on non-surgical treatments.
