The aim of this study is to explore the correlations between fasciology and yin yang doctrine. Professor Yuan developed fasciology by three-dimensional reconstruction of connective tissue (fascia) in the trunk and limbs of the human body and tracing back to tissue origins in light of biological evolution and developmental biology. Fasciology states that the human body can be divided into two systems: the supporting-storing system and the functional system. This article elaborates on the roles of the two systems and their mutual relationship. The two systems are used to analyze the yin,the yang, and their relationship. The two systems are promoted but also restricted in different contexts. The supporting-storing system is formed by undifferentiated connective tissue and provides undifferentiated cells and nutrients for differentiated cells of the functional system. Thus, the supporting-storing system could be classified as quiet, similar to yin. The functional system continuously maintains the various functional activities of the human body. Thus, the functional system could be classified as active, similar to yang. In interpreting the yin yang doctrine from the point of view of fasciology, yin can be compared with the supporting-storing system and yang can be compared with the functional system.

林炳五,梁千會,劉一增 弘益大學校 1985 弘大論叢 Vol.17 No.2

Correlation of catalytic activity for the oxidation of CO and sensor response to CO was investigated. The perovskite-type oxides prepared by partial substitution of LaFeO₃with other 3d transition metal M to give LaFe₁_хMхO₃. The catalytic activity of LaFe₁_хCOхO₃(x=0 to 0.2) increase in X, but the highest sensor response was achieved at x=0.1. It was found that the sensor response increased in proportion to the catalytic activity, provided that the apparent activation energy for electrical conduction was unaffected by the substitution.

Objective: The purpose of this study was to compare preceptors and new graduate nurses on their perception of preceptor teaching effectiveness. Methods: The participants were 90 new nurses and 90 preceptors who worked in A medical center. The data were collected from July 1 to September 30, 2008. A cross-sectional descriptive survey was done using a structured questionnaire. Results: New nurses' perception (4.07±.44) of the preceptor teaching effectiveness was significantly higher than perception of the preceptors (3.57±.37). Fifty five percent of new graduate nurses reported a lack of coherence in the preceptor's practice guidelines. For 5 causal factors classified on the teaching effectiveness, the factor of 'Professional knowledge and ability' showed the highest score, but 'Interpersonal and communication skill' got lowest score for both group. Preceptors responded that they did not have enough time to teach well because of their heavy workloads. Conclusions: These results suggest that the preceptors need appropriate compensation and education opportunities, and new graduate nurses need consistent education by the teaching professionals. Therefore, it is important to give preceptors full charge of the preceptorship. Also, it will be necessary to develop education programs to enhance interpersonal and communication skill for preceptors and new nurses.

A Study on E-commerce Recommender Systems Based on LSI and Fuzzy Model

권영직,양춘우,권동훈 대구대학교 정보통신연구소 2009 情報通信硏究 Vol.6 No.1

This paper combines two analytical techniques to create a model that not only narrows product choices but also producesa prioritized product list of recommendations tailored to a specific customer. Specifically, the paper proposes to create a recommender system based on applications of Latent Semantic Indexing (LSI) and Fuzzy Synthetic Judgment (FSJ). The application ofthese two analytic models will serve a two-fold purpose. Latent Semantic Indexing will enable the model to account for incomplete rating information in the collaborative rating matrix so that the completed rating matrix can then be decomposed using the Singular Value Decomposition (SVD) method. Fuzzy Synthetic Judgment will then provide a prioritized list to the customer of recommended selections. In order to provide a clearer understanding of the proposed recommender process, the authors will demonstrate the requisite calculations through an application. In addition to clarifying the process, the example will serve to help validate the proposed model.

In the five years since 1993 Malaria has made a ceaseless attack on the native Koreans as an indigenously formed disease in addition to the imported one. This study was aimed at clinical symptoms and signs of Malaria which had occurred indigenously in Cheon-Nam. 18 cases were reviewed retrospectively in this study which was composed of 17 men and 1 woman. They were admitted to Chosun Hospital because of the indigenous Malaria in 1998. Fever and chill , the most frequent symptoms in early stages made a 100% occurrence followed by general myalgia(89%) and headache(83%). Physical examination of those admitted showed the splenomegaly most frequently in 61% of the patients. It took four to ten days to visit the hospital since the symptoms first occurred in the patients. Gametocytes among the Malarial life cycle were observed most commonly (91.3%) in the occurrence of the disease and the prestages of the life cycle as well. The hematologic abnormalities observed was Anemia(89%), Thrombocytopenia(61%), and Neutropenia(50%) in the order named. On the third hospital day since giving the standard Malarial drugs parasitemia decreased remarkably (1540/㎕ : Mean parasitic concentration) and 28th day of treatment no parasitemia were found. In conclusion the patients suffering from malaria in Cheon-Nam had been in an armistice area and the symptoms were so relatively mild that the responses to treatment were good and relapses occurred. But, it requires further epidemiologic survey and more concern about the indigenous Malaria.

The intracellular parasite Babesia microti is among the most significant species causinghuman babesiosis and is an emerging threat to human health worldwide. Unravelling thepathogenic molecular mechanisms of babesiosis is crucial in developing new diagnosticand preventive methods. This study assessed how priming with B. microti surface antigen1 (BHSA 1) and seroreactive antigen 5-1-1 (BHSA 5-1-1) mediate protection against B. microti infection. The results showed that 500 µg/ml rBMSA1 and rBMSA5-1-1 partiallyinhibited the invasion of B. microti in vitro by 42.0±3.0%, and 48.0±2.1%, respectively. Blood smears revealed that peak infection at 7 days post-infection (dpi) was 19.6%,24.7%, and 46.7% in the rBMSA1, rBmSA5-1-1, compared to the control groups (healthymice infected with B. microti only), respectively. Routine blood tests showed higher whiteblood cell, red blood cell counts, and haemoglobin levels in the 2 groups (BMSA1 andBMSA5 5-1-1) than in the infection control group at 0–28 dpi. Moreover, the 2 groups hadhigher serum interferon-γ, tumor necrosis factor-α and Interleukin-17A levels, and lowerIL-10 levels than the infection control group throughout the study. These 2 potential vaccine candidate proteins partially inhibit in vitro and in vivo B. microti infection and enhancehost immunological response against B. microti infection.

Yu-Chun Yang,Ying Qin,Xian-Xue Wu,Cong-Fang Xia,Yan-Lin Meng,Bin Zhou,Yan-Qing Ye,Xue-Mei Gao,Yin-Ke Li,Qiu-Fen Hu 대한화학회 2015 Bulletin of the Korean Chemical Society Vol.36 No.4

Two new flavones, 5-hydroxy-8-hydroxymethyl-7,4′-dimethoxy-flavone (1) and 6-hydroxy-8-hydroxymethyl-7,4′-dimethoxy-flavone (2), together with six known flavones (3–8), were isolated from the bark of Lindera caudata. The structures of 1–8 were elucidated by spectroscopic methods including extensive 1D and 2D NMR techniques. Compounds 1–8 were evaluated for their anti-tobacco mosaic virus (anti-TMV) activity. The results showed that Compounds 1 and 2 showed high anti-TMV activity with inhibition rates of 31.2 and 28.8%, respectively. These values are close to those of positive control.

Background: Spontaneous recovery of severe alopecia areata is rare and the condition is difficult to treat. Objective: The aim of this study is to investigate and compare the effects and safety of steroid pulse therapy between oral and intravenous administrations between 1999 and 2010 at the Department of Dermatology, National Cheng Kung University Hospital. Methods: Data were retrospectively retrieved. A satisfactory response was defined as more than 75% hair regrowth in the balding area. Results: A total of 85 patients with more than 50% hair loss were identified and treated, with an overall satisfactory response rate of 51.8%. The mean follow-up time was 37.6 months, with a relapse rate of 22.7%. Patients with alopecia areata (hereafter, AA) of recent onset within one year showed higher response rates (p< 0.001) and lower relapse rates compared to patients with AA persisting for more than 1 year. Further, even in patients with alopecia totalis, alopecia universalis or ophiasis type, early treatment resulted in a satisfactory response rate of 47% among the treated patients. In general, oral therapy was as effective and well-tolerated as intravenous therapy. Conclusion: The response rate is determined by disease severity and time of intervention, not by the administration form of steroid pulse therapy. Oral steroid pulse therapy can be considered as the first-line treatment for patients with severe AA of recent onset within one year. (Ann Dermatol 25(4) 471∼474, 2013)

양측성 부신과증식 및 부신피질 기능항진증의 임상증상을 수반하는 ACTH 분비성 뇌하수체 선종에의한 쿠싱병온 대분분의 경우 선종의 크기가 작아 종래의 단순두개 X-선 촬영이나 근래에 도입된 고해상 전산화 뇌단층 촬영(computed tomogram, CT) 및 자기공명영상(nuclear magnetic resonance image, MRI)검사로도 약 30∼50%에서는 이상소견을 발견하지 못하는 것으로 보고되고 있다. 최근 혈관도자술을 통하여 하추체 정맥동(inferior petrosal sinus) 혈액을 체취후 호르몬 검사를 시행하여 뇌사수체 선종을 진단하는 방법이 도입되었는데, 방사선학적 검사로 발견하기 어려운 뇌하수체 미세선종의 진단에 도움을 주고 있다. 이에 저자는 1988년 6월부터 1990년 6월까지 연세의대 부속 세브란스 병원에서 임상적 증상 및 내분비학적 소견상 쿠싱병을 보였으나, 방사선학적 검사상 뇌하수체 선종을 뚜렷히 진달할수 없었던 7예의 환자를 대상으로 혈관도자술 검사로 채취한 양측 하추체 정맥동혈액의 호르몬 검사를 시행하여 다음과 같은 결과를 얻었다. 1) 대상 환자는 남자 3예, 여자4예 이었으며, 연령은 18세에서 46세로 평균연령은 33세이었다. 2) 기저혈청 cortisol 치는 7예중 5예에서 증가되었으며, 혈청 부신피질 자극호르몬(adrenocorticotropin, ACTH)치는 3예서만 증가된 소견을 보여 주었고, 4예는 정상이었다. 3) 저용량 덱사메타존 억제 검사상 전예에서 억제소견을 보이지 않았으나, 고용량 덱사메타존 억제 검사에서는 7예중 6예에서 억제소견을 보였다. 4) 전산화 뇌단층촬영상 종양의 위치를 6예에서 확인 할 수 없었으며, 핵자기 공명영상 검사를 시행한 5예중 3예에서 종양의 위치를 의심할 수 있었다. 5) 종양이 존재하는 편측 하추체 정맥동으로부터 추출한 혈청 ACTH 치는 7예중 4예에서 1.4배 이상 의의 있게 증가 되었으며, 농도차이가 나지 않은 3예중 2예에서 부신피질 자극 호르몬 방출호르몬(corticotropin releasing hormone, CRH)자극 검사를 시행하여 이중 1예에서 종약측 하추체 정맥동내 ACTH 치가 의의있게 소견을 보여 전체 환자중 5예에서, 하추체간 ACTH 농도차에 의한 종양의 편측화가 가능하였고, 수술 소견상 같은 위치에 종양이 확인되었다. 6) 종양의 편측화가 불가능 하였던 2예는 수술소견상, 뇌하수체 중앙 부위에 종양이 위치함이 확인되었다. 7) 하추체 정맥동간 prolactin과 성장호르몬(growth hormone, GH)치는 종양측 정맥동의 농도가 증가된 경우가 중앙부위 종양 2예를 제외한 5예중 4예와 3예에서 각각 의의있게 증가하였다. 8) 수술후 생화학적 검사 및 호르몬 검사를 시행한 6예중 5예는 완전관해소견을 보여 주었으며, 1예에서 외래 추적 검사상 재발이 확인되었다. 이상의 결과로 쿠싱병에서 고해상 전산화 뇌단층촬영 및 자기 공명영상 검사상 종양의 존재여부가 불분명할 때, 혈관도자술을 통한 하추체 정맥동 혈액채취후 호르몬 검사는 수술전 종양의 위치를 확인하는데 도움이 될 것으로 사료된다. Pituitary adenoma, Cushing`s disease is characterized by typical clinical symptoms like bilateral adrenal hyperplasia and adrenal cortex hyperfunctioning and is usually small in size, making it very difficult to detect by conventional plain skull X-ray and recently developed high resolution brain computed tomogram (CT) and magnetic resonance image (MRI) are reported to detect only 30% to 50% of all cases. Currently, detection of hormone levels through inferior petrosal sinus blood sampling is available, facilitating the diagnosis of pituitary microadenoma. This clinical study was designed to detect the patients with Cushing`s disease who were hospitalized in Yonsei University Severance hospital from 1988 to 1990. And all of them are highly suggestive of Cushing`s diseas by clinical and endocrinological findings, but can not be ascertained by radiological test. In a total 7 patients were engaged, and by using bilateral inferior petrosal sinus sampling and hormone assay, the results are as follows. 1) Low dose dexamethasone suppression test did not show suppression in all patients performed the test but high dose dexamethasone suppression test showed suppression in six patients out of seven (85.7%). 2) Basal plasma ACTH level showed normal in four out of seven patients (57.1%). 3) Pituitary CT scan sowed normal or equivocal findings in six patients except one and MRI showed low density in two cases among five. 4) The plasma ACTH levels of inferior petrosal sinus on the ipsilateral side to the tumor were significantly increased in four cases out of seven (57.1%) compared to those of contralateral side but remaining one case showed significant ACTH increase on CRF stimulation test in tumor side and remaining two cases were found to be a midline tumor after surgery. 5) The prolactin and growth hormone levels of inferior petrosal sinus on the ipsilatral side to the tumor were increased in five cases (71.4%) and in three (50%) of six cases respectively compared to those of contralateral side. 6) After surgery, five patient`s biochemical findings showed complete remission but one patient was found to be recurred by OPD follow up. It was concluded that the hormone assay by inferior petrosal sinus sampling could provide important information about diagnosis and tumor lateralization in Cushing`s disease which was biochemically and radiologically inconclusive.
