The Korean government introduced a private-initiative park project to prevent further environmental damage caused by the abolition of parks. The private-initiative park project is expected to affect the connectivity of the green space system by creating a part of the park site as a non-park facility. The purpose of this study is to analyze the change in the connectivity of the green space system in relation to the private-initiative park project. The spatial scope of this study is in Cheongju, Korea. There were 8 private-initiative park projects selected as research subjects. The IIC indicator and d_IIC indicator, which are widely used in the analysis of green space connectivity, were used as analysis methods. Changes in connectivity according to four scenarios were simulated. Upon analysis, the results revealed that private-initiative park projects can reduce the overall connectivity of green spaces. The connectivity of private-initiative park projects can be improved compared to the situation of unplanned development while maintaining the current state. Lastly, changes in connectivity due to private-initiative park projects vary by region. This study was meaningful as an early study that analyzed private-initiative park projects in terms of the connectivity of green areas and is expected to be used for the improvement of the park and green space system in the future.

Background: Micafungin, a potent inhibitor of 1,3-β-D-glucan synthase, is a novel antifungal agent of the echinocandin class. In vitro study showed that micafungin was effective against Aspergillus species as well as Candida species, but clinical data on the prophylactic efficacy against invasive fungal infections (IFIs) other than candidiasis are still lacking. Materials and Methods: We identified 60 consecutive adult hematopoietic stem cell transplantation (HSCT) recipients who received at least 3 doses of micafungin during neutropenic period. Micafungin was started as an alternative in patients who were intolerant or had adverse events (AEs) to primary prophylactic antifungal agents. We retrospectively reviewed the medical records and analyzed the efficacy and safety of micafungin for prophylaxis against IFIs. Results: The patients either had autologous (n=9) or allogeneic (n=51: 1 syngeneic, 24 sibling, 26 unrelated donor) HSCT. Itraconazole oral solution (n=58) was the most frequently used first line antifungal agent for prophylaxis and was administered for median 11 days. The most frequent cause of switch to micafungin was vomiting (n=42). The duration of neutropenia and micafungin administration was median 13 and 12 days, respectively. A successful outcome was achieved in 45 (75%) patients. Empirical antifungal therapy was initiated in 13 (22%) patients. There were 2 cases (3.3%) of breakthrough fungal infections which comprised a probable invasive pulmonary aspergillosis and a possible invasive fungal sinusitis. There was no case of invasive candidiasis. A total of 53 (88%) patients experienced at least one AE regardless of causality during micafungin administration. The most frequent AEs were hypokalemia, vomiting, diarrhea, and elevated serum aspartate aminotransferase or alanine aminotransferase. Among the aforementioned AEs, only 1 case of diarrhea could be classified as a probable relation with micafungin when causality was assessed. There was no AEs that caused discontinuation of micafungin. Conclusions: Micafungin seems to be a safe and effective agent for prophylaxis of IFIs including aspergillosis as well as candidiasis in HSCT recipients. However, further large, prospective, and randomized comparative studies are warranted for aspergillosis.

IMF체제하의 국민생활체육 정책방향

박종욱,박영표 대불대학교 1998 論文集 Vol.4 No.1

The economic crisis that korea is experiencing has brought out commodity price hikes, wage cuts and an ever higher unemployment rate, and is threatening the people's lives. In addition, the crisis has increased the instances of homelessness, suicide and, most importantly, problems of public health. At this juncture, facing the national crisis, I believe, that the most critical work to be done is to establish the more solid spirit of nationalism and to foster the sense of the common bods among the people. It is also time to examine the direction of government policies to boost the morale of the people. The aim of this research is to foster a deeper understanding of the social problems brought out by the IMF stewardship by consulting previous publications and documents, and to propose policy directions for weathering the problems especially those related to public health. 1. National physical education should be instituted to instill health awareness in its social and mental aspects as well as the physical. 2. All facilities related to physical exercise whether established by corporations, educational institution, private individuals, or governments should be more easily accessible to the general public. The expansion and further development of athletic facilities at the governmental level need to be more strongly pursued. 3. The development and distribution of a wide variety of health and sports programs should satisfy the athletic desires of the nation.

From April to October 2001, we studied on vegetation of 60 plots through the methods of Braun-Blanquet at Cheonsaengsan, Yuhaksan and Supdemisan in Gyeongbuk. Through the methods of interspecific affinity analysis, DECORANA and TWINSPAN the patterns of plant communities of 60 were analysed. It showed 6 communities at Cheonsaengsan, 5 communities at Yuhaksan, 6 communities at Supdemisan and total appearance of 128 species and covered with 50∼95% of tree layer, 20∼90% of shrub layer, 20∼90% of herb layer. As the result of interspecific affinity analysis it showed one big specific complex composed with 52 species and the 60 plots were divided into 4 groups by classification and ordination. One big species complex as a result of affinity analysis and eigenvalue of 0.303 at first step by classification indicate that Cheonsaengsan, Yuhaksan and Supdemisan are in developing stage of succession.

In The general enhancement and the wide diffusion of technologies in manufacturing products has made a great change in evaluating distintiveness of a product from a functional point of view to a communicational one. Teenagers consumers are ready to play more for the mental value of a product than for its practical value these days. It is a time of communication between consumers and products. Most of the marketing tools are concentrated on how to draw consumers' attention, how to start their communication with products, how to prolong their communication and how to induce their next communication. Of late, characters started to be noted as one of the most effective media to enhance the quality of communication between products and Teenagers. Original features of characters such as eye-catching power, story-telling expressions, incitation of imagination, etc. are regarded as key elements to get the communication started. In the Krean market as well as in the global market, character merchandising has become common in promoting teenagers' products.

효율적인 단정도/배정도 승산을 위한 이중모드 승산기

박종화,이종남,신경욱 金烏工科大學校 1999 論文集 Vol.20 No.-

High-speed/low-power/low-cost multipliers play an important role in micro-processors and digital signal processors because multiplier core not only occupies a signigicant percentage of the silicon area, but also limits the overall performance. This paper describes a design of dual mode multiplier (DMM) that performs single- and double-precision multiplications using hardware required for single-precision multiplication. We propose an efficient algorithm which partitions a double-precision multiplication into four single-precision sub-multiplications and then computes them with sequential accumulations. When compared with conventional double-precision multipliers, our approach reduces hardware complexity required for double-precision multiplication by about one third at the expense of increased latency. The DMM has been designed using a 0.25-㎛ 5-metal CMOS technology, and contains about 25,000 transistors on the area of about 0.77×0.40㎟. The HSPICE simulation results show that the DMM core can safely operate with 150-MHz clock at 2.5-V, and the estimated power dissipation is about 110-mW at double-precision mode.

DSP 응용을 위한 작은 오차의 절사형 Booth 승산기 설계

박종화,신경욱 金烏工科大學校 2000 論文集 Vol.21 No.-

The paper describes a design of low-error truncated Booth multiplier for digital signal processing(DSP) applications. Given two N-bit inputs, the truncated multiplier generates N bits (instead of 2N bits) product by eliminating the N least-significant bits of product. The truncation of product to N bits is achieved by omitting about half the partial product generator and adders, but a significant truncation error is introduced in the resulting product. To keep the truncation error to a minimum, an efficient carry-generating circuit is devised, which feeds the revising information to the carry inputs of the retained partial product adders. When compared with non-truncated parallel multiplier, the truncated multiplier reduces about 35%~40% of the chip area. Error analysis shows that the proposed approach has lower error than other fixed-width multipliers and is cost-effective. As a result, the truncated multiplier is suitable for an area-efficient and low-power implementation of multimedia and DSP functions.

목 적 : 진폐증은 분진으로 인해 인체의 면역기전이 작용하여 폐섬유화가 진행되는 질환으로, 인체의 면역기전에 작용하는 구리와 아연은 진폐증의 병리적인 진행과정인 폐섬유화에 관여한다. 본 연구의 목적은 초기진폐증 유소견자와 진행된 진폐증 환자의 혈청 구리와 아연의 농도를 정상인과 비교함으로써 체내 구리와 아연의 농도가 진폐증의 섬유화의 진행정도에 따라 변동함을 밝히고, 이를 이용하여 폐섬유화의 진행정도를 추정할 수 있는 지표를 제시하고자 한다. 방 법 : 진폐정밀기관에 내원한 초진내 원자 100명과 진폐요양기관에 입원한 진폐증 환자 100명을 선정한 후 흥부사진소견을 ILO 분류법의 진폐진행정도에 따라 각각 세 군(Stage Vl, V2, V3 & Stage Pl, P2, P3)으로 구분한 후 각 군의 혈청구리와 아연의 농도를 비교분석하였다. 대조군으로는 폐결핵, 심근경색, 뇌경색을 경험한 적이 없는 일반인 100명을 선정하였다. 결 과 : 초진내 원자군의 혈청 구리농도는 섬유화의 진행단계에 따른 유의한 차이를 보였으며, Stage V3에서 가장 높았다. 입원환자군에서는 혈청 구리농도가 대조군과 유의한 차이를 보이지 않는데 (p=0, 152), 이는 입원환자의 불량한 영양상태와 건강상태 때문인 것으로 추정된다. 초진내원자군과 입원환자군의 혈청 아연농도는 섬유화의 진행에 따라 통계적인 차이를 보였으며, Stage V2와 Stage P2, P3에서 각각 대조군에 비해 유의하게 낮았다. 혈청 아연과 구리농도의 비또한 양군에서 섬유화의 진행에 따라 의미있게 높았는데, 섬유화가 현저히 진행된 단계 (Stage V3, Stage P2, P3)에서 대조군과 의미있는 차이를 보였다. 결 론 : 초진내 원자와 입원환자의 혈청 Cu/zrl 비는 섬유화의 진행정도가 현저할수록 대조군에 비해 유의하게 높게 나타났다. 진폐증 환자들의 혈청 Cu/zn 비는 진폐증의 폐섬유화의 진행정도를 추정함에 있어 상당히 유용한 지표로 이용될 수 있으며, 폐섬유화의 진행과정에서의 혈청 구리와 아연의 작용기전을 이용한 치료방법의 마련에도 도움이 될 것으로 판단한다. Objectives : Copper and Zinc, the trace elements of a living body, take a part in immunologic mechanism and induce the pulmonary fibrosis which is the pathologic progress of pneumoconiosis. This study was performed to assist the identification of the pathologic process of pulmonary fibrosis in pneumoconiosis. Methods : The subjects of thls study was 200 diagnosed persons as pneumoconiosis, of whom 700 persons was the visitors in the outpatients departments of pneumoconiosis and 100 admissive pneumoconiosis patients. The serum copper and zinc are measured and compared. Results : The mean serum copper concentration of visitor group was significantly higher than that of control group, and that of stage V3 subgroup of visitor group was highest because of their advanced fibrosis. But, there was not the difference of serum copper concentration between patient and control group. We thought that the reason was poor nutritional and health status of the patient. The mean of serum zinc concentration of visitor and patient control was lower than that of control group. As the degree of pulmonary fibrosis was more severe from stage Vl, V2, V3 of visitor to stage Pl, P2, P3 of patient, the mean of serum zinc concentration was lower. The ratio of serum copper/zinc of visitor and patient was higher than that of control, and that of patient was higher than that of visitor. Those results showed that the ratio of serum copper/zlnc ratio more greatly expressed the degree of progression of pneumoconiosis than only copper or zinc concentration by adjustment of nutritional and health status of the patient. Conclusions : As above study results, the degree of pulmonary fibrosis of pneumoconiosis could be estimated by means of serum copper/zinc ratio.
