This study develops theoretical frameworks based on Total Project Management (TPM) methods and applies computer-aided TPM programs to the public arena. It implies that the current practices hinged on passive or limited tactics should be replaced with the TPM strategies which are initiated in the private sector. That is, the major problems of the existing project management can be summarized as the indirect and unilateral systems, the restrictive scopes, and non-scientific management activities. In contrast, the TPM focuses on total management among diverse functions covering the early stage of suggestion up to the post-operation. 'Therefore, both information-sharing and total management activities are possible within the TPM system. For these purposes, an independent organization operation and composition is essential. Furthermore, it also proposes the harmonized structure among areas of scope, quality, cost, time, risk, communication, resources, and procurement management. At the same time, the study finds that roles of negotiators or arbitrators to accommodate diverse opinions among various interest groups are prerequisite for the suitable application of the TPM strategies in the public sector. This thesis presents two-phased practical policy alternatives. Compared with the traditional management activities depending on the hierarchical structure between expert groups and public authorities, the alternative operation of special task force teams is recommendable if the public sector has the sufficient capacities to handle projects in the long run. In specific, the wide application of computer-aided program is the most promising and reliable because it can guarantee the scientific and objective management from the beginning of project design. In order to evaluate the feasibility of program application, the thesis examines a real example dealing with the time-schedule management in Cheong-ju Bongmyong-Shinbong Land Rearrangement Project. As shown in the case study, a series of analyses using management programs can make it possible to quantify risk factors within the total networks, which are also supplemented by additional information for the necessary rescheduling. In addition, the public authority can utilize the management program to simplify the complicated factors concerned with public projects. Nonetheless, it should be kept in mind that the final decision is man-made, not machine-made: we can only be supported by the public decision-making information.

Abstract: As known in clinical trial like DCCT, UKPDS, tight glycemic control is essential to prevent complications from diabetes mellitus(DM). In type 2 diabetes taking multiple medication, nonadherence to medications is common problem. The aim of our study is to investigate adher-ence rate of patients with type 2 DM and to evaluate association between many factors including adherence rate and HbA_(1C). 441 patients with type 2 DM who visited Busan National University Hospital endocrine internal department from Aug 13 to Sep 2, 2008(3weeks) were enrolled. We conducted a man-to-man questionnaire survey about general knowledge about diabetes mellitus, medicine and adherence, and measured HbA_(1C). Among them, 305 patients taking oral hypo-glycemic agent(OHA) were analyzed to investigate correlation between adherence rate and glycemic control. We studied 305 patients(male 126, female 179, average age 61.2±9.8 years, DM duration 8.6±6.4 years, average adherence 88.8±16.2%, average HbA_(1C) 7.03± 1.18%). HbA_(1C) showed significant relation with DM duration(r=0.137, p=0.017), number of aHA in regimen (r=0.135, p=0.018), dosage frequency(r=0.132, p=0.026), Medication Refill Adherence(MRA)(r=-0.124, p=0.030) and adherence(r=-0.168, p=0.003). Adherence had significant relation with MRA(r=0.148, p=0.010) but didn't have statical corelationship with DM duration, number of aHA and dosage frequency. Patients that their adherence rate exceed 90% took fewer OHA(p=0.011) and went on a better dietary treatment(p=0.007). In patients controlling diabetes mellitus with aHA, when adherence rate and MRA was higher, HbA_(1C) was lower. As a result, to improve adher-ence rate, it is necessary to enhance patient education, do careful consideration about prescrip-tion medicine number and dosage frequency

예은주,배만종,김수정,박창호 경산대학교 생명자원개발연구소 2003 생명자원과 산업 Vol.7 No.-

본 연구는 인삼의 가공방법을 개발하고 제품을 다양화하기 위한 기초 자료를 확립하고자, 우리나라의 전통주인 약주로 증자한 후 홍삼의 일반성분과 ginsenoside의 함량을 분석하고 갈색도 및 탁도의 변화를 알아보았다. 또한 항암효과를 검증하였던바 그 결과를 보고하고자 한다. 1. 백삼과 홍삼, 증자 횟수별 인삼의 갈색 변화를 보기 위해서 각 인삼의 60% 에탄올추출물의 갈변의 측정 결과 갈변의 전구물질과 중간생성물 및 fufural, 갈색계의 색소, 탁도 모두 증자횟수가 증가 할수록 값이 증가하였다. 그리고 백삼, 홍삼 A1는 3가지 항목에서 모두 비슷한 경향을 보였으며, 상대적으로 A3에서 높은 값을 보였다. 2. HPLC상으로 total ginsenoside의 함량을 측정한 결과 백삼 28.20mg/g, 홍삼 421.10mg/g이고 A1~A9에서는 46.10~76.80mg/g으로 홍삼과 백삼보다 증자 횟수가 증가 할 수록 total ginsenosied 함량이 증가하였다. 3. HPLC상에서 분석한 증자 횟수별 인삼의 ginsenosides(G-Rb₁, -Rb₂, -Rc, -Rd, -Re, -Rf, -Rg₁, -Rg₂, -Rg₃)의 함량변화는 G-Rc, -Rd, -Re는 1회 증자한 A1에서 함량이 증가 하다가 증자 횟수가 증가 할수록 다시 함량이 감소하였으며, G-Rg₂, -Rg₃는 증자 횟수와 비례하여 함량이 증가하는 경향을 보였다. 4. 인체유래 간암세포(Hep3B)에서의 항암효과 검증실험에서는 물, 60%에탄올 추출물을 각각 1000ppm, 2500ppm, 5000ppm으로 처리 한 후 세포 증식 억제율을 확인하였다. 백삼은 모든 처리군에서 미미한 증식억제 효과가 있었으나, 홍삼은 60%에탄올 추출물 5000ppm에서 54.52%, A9에서는 96.28%의 현저한 세포증식억제 효과가 있었다. A9가 Hep3B에 대해서 백삼과 홍삼보다 세포 증식 억제율이 더 높은 것을 확인 할 수 있었다. 이상의 결과로 볼 때 약주를 이용해서 증자한 홍삼이 백삼이나 일반홍삼보다 총 사포닌, 진세노사이드의 함량이 증가하였고, 기능과 효능이 증강된 것으로 확인되어 우수함이 입증되었다. 또한, 홍삼정과, 절편정과 등 제품의 다양화와 품질개선에 기여할 것으로 기대된다. 향후 증자 방법, 압력, 온도, 및 약주 등의 제조 조건에 따른 지속적인 연구가 요청된다. This study takes place to establish basic data to develop various ginseng-processing methods and products. It analyzed components and quantity of ginsenoside in red ginseng after brewing with the traditional medicinal wine as well as the brownness and impurity level changes, and verified anti-oxidization and anti-cancer effects. The following is the founding of these analyses. To examine the changes in the brownness of white and red ginseng, premonitory materials of 60% ethanol extracts were examined As the result of these examinations, all of the values of examined matters premonitory materials, mid products, Fufural, coloring matters and impurity level were increased as the brewing continued. And the brownness level for white and red ginseng was similar in Al and the values were relatively high in A3. The total Ginsenoside on HPLC was 28.20㎎/g for white ginseng and 42.10㎎/g for red ginseng. The quantity of total Ginsenoside was increased as the brewing continued as 46.10∼76.80㎎/g was shown in A1∼A9. To see the quantity changes of Ginsenosides(G-Rbi, -Rte, -Re, -Rd, -Re, -Rf, -Rg₁, -Rg₂, -Rg₃) contained in ginseng on HPLC, the quantity of G-Rc, -Rd, -Re were increased in Al the first brewing and decreased as the brewing continued. The quantity of G-Rg2, -Rg3 was increased proportionate to the number of times for brewing. In an anti-cancer test in liver cancer cells(Hep3B) extracted from human body, each of water and 60% ethanol extracts were processed with 1000ppm, 2500ppm, and 5000ppm and checked the multiplication restrain rate. All of the processing groups in white ginseng have minimum multiplication restrain rates, but red ginseng has 54.52% at 60% ethanol extract 5000ppm. At A9, 96.28%) of cell multiplication restrain effects were shown. Comparing Hep3B to A9, white ginseng has higher restrain effects than red ginseng. As seen in the above results, the reinforced red ginseng using the medicinal wine has higher total saponin and ginsenosides, as well as with increased functions and effects leading the superiority. And it is possible to use Red Ginseng Jung Kwa; Jung Kwas with flower pattern imprinted, and expect to increase the opportunities to use the extracts. Later, when brewing the pressure, temperature, and medicinal wine can be examined to continuous studies.

6주간 고지방식이를 섭취한 흰쥐에 있어 송화분과 탈지 송화분이 혈청과 간장에서의 지방 축적과 대사에 미치는 효과를 관찰하였다. 혈청에서의 total lipid, total cholesterol 농도는 고지방 식이군에 비해서 탈지 송화분과 송화분 투여군이 유의적으로 감소하였다. 혈청에서의 triglyceride 농도는 탈지 송화분과 송화분 투여군이 고지방 식이군과 비교했을 때 뚜렷한 감소를 보였으며, 이는 정상군과 비슷한 농도를 나타내었다. 혈당농도는 송화분, 탈지 송화분 투여군에서 유의성 있게 감소하였다. 간장을 조직학적으로 관찰한 결과, 고지방식이로 인한 조직의 지방 침착은 송화분 투여군에서 다소 억제함을 보였다. 이상의 결과를 미루어 볼 때 송화분은 동맥경화증 및 순환기계 질환의 예방과 치료에 효과적일 것으로 사료된다. Effect of pine pollen and defatted pine pollen on lipid accumulation and metabolism in serum and liver were investigated with rats fed high fat-supplemented diets for 6 weeks. Concentrations of total lipid and total cholesterol in serum significantly decreased in the experimental groups(treated with pine pollen and defatted pine pollen) compared with the control group. Concentration of triglyceride in serum was remarkably lower than that of control group. This was similar to that of normal group. Concentration of glucose in serum was significantly lower in the experimental group. It was observed from photographs of hepatic tissue in rats that pine pollen inhibits the lipid accumulation induced by high fat diets.
