본 연구는 수피 부산물 비료의 돈분 부산물 비료의 부숙단계별 시료의 유기물 분획의 함량 변화, Δlog K값과 RF값 등의 분광학적 특성 변화, 원형여지 chromatograp의 변화를 측정하여, 부숙도의 판정 기준 설정을 위한 기초 자료로 활용하는데 그 목적이 있다. 그 결과를 요약하면 다음과 같다. 수피와 돈분 부산물빌 중 HA-C와 FA-C의 함량은 대체로 부숙이 진행됨에 따라 감소하는 경향이었고, HA-C/FA-C 비는 증가하였다. 수피와 돈분 부산물 비료의 Δlog K값은 부숙이 진행됨에 따라 감소하였으며, RF값은 증가하였다. 생수피의 부식산 형태는 R_p 형태였으나, B형태를 거쳐 120일경과 후 A형태로 변화하여 거의 완숙상태에 도달하였으며, 돈분 부산물 비료의 경우 40일경과 후에도 B형태로 나타나 유기물질의 부숙이 진행중인 것으로 판단되었다. 수피부산물 비료의 원형여지 chromatograph는 120일경과 후에 규칙적인 톱니 모양을 하고 있어 완숙단계에 이른 것으로 판단할 수 있었으나, 돈분 부산물의 경우는 40일이 경과한 후에도 부분적으로 불규칙적인 모양을 하고 있어 부숙이 진행되고 있는 상태인 것으로 판단할 수 있었다. Changes of the spectroscopic characteristics of the organic matter fractions and circular filter paper chromatograph were assessed for the bark and piggery manure composts during the composting. as an approach to base the criteria of the compost maturity evaluation. Contents of humic acid-C (HA-C) and fulvic acid-C (FA-C) in both bark and piggery manure composts were decreased as the composting got closer to maturity, but the ratios of HA-C/FA-C were increased. During the composting. Δlog K values were decreased, but RF values were increased. Humic acid of the mature bark compost after 120 days of composting was A-type, as compared to Rp-type for the raw bark and B-type for the immature compost. However. humic acid of the mature piggery manure composts after 40 days of composting was B-type, indicating the humification of the organic matter fractions continued at this stage. Circular filter paper chromatograph of the mature bark compost exhibited the regular sawteeth pattern at the edge, but that of the mature piggery manure showed an irregular sawteeth pattern. Results demonstrated that spectroscopic characteristics and circular filter paper chromatograph of the organic by-product composts might be employed for the compost stability assessment.

주요 컨테이너항만의 항만요율에 관한 비교연구

하명신 국제무역학회 2003 국제무역연구 Vol.9 No.2

본 연구에서는 아시아의 주요 항만을 선택하여 각 항만간 요율의 차이를 비교하고자 하였다. 특히 부산항의 경쟁력이 낮은 항만요율에 기인한 것이라는 선행연구를 바탕으로 과연 부산항의 항만요율이 경쟁항만에 비해 낮은 지와 여타 항만에 비해 어떤 요율이 낮은지 그리고 이러한 항만요율에 대한 개선책이 무엇인가를 식별하고자 하였다. This research tries to examine port tariff of major Asia ports and compare its difference between each ports. Basically the competitive power of Busan port is some low in literature review and thus the tariff of the port is also lower than competitive ports. This study is trying to identify how much lower it is than other ports. This study has several results as follows: First, container tax in Busan port tends to raise up the whole port tariff. This will be eliminated by port authority to strengthen its competitiveness. Second, loading and unloading charge and charge for custody need to reorganize in Busan port. In case of Hong Kong, they are main revenues and then Busan port need not impose lower loading and unloading charge and charge for custody than its competitive ports. Third, port tariff criterion needs to be standardized because it is so complex and different by port and even country.

申榮男,李命夏 대구대학교 기초과학연구소 1987 基礎科學硏究 Vol.4 No.-

Isomer shift and quardrupole splitting of the ferric-and ferro-cyanide of potassium in accordance with temperature change in low temperature were studied by Mo∼ssbauer spectroscopy method. K₃Fe(CN)_(6) shows isomer shift and quardrupole, the other hand K₄Fe(CN)_(6)3H₂O shows only isomer shift. Two samples show that isomer shift is decreased by temperature decrease and quardrupole splitting is increased by temperature decrase. Accordingly selectron's contribution is increased by temperature decrease, a nucleus get to be more stable state. And it is showed that the nuclear state of K₄Fe(CN)_(6)3H₂O is more stabler than that of K₃Fe(CN)_(6).

하명신,장병기,배상욱 한국물류학회 2005 물류학회지 Vol.15 No.1

베트남은 동남아시아 국가들중 가장 경제성장가능성이 높은 국가 중의 하나이다. 본 연구는 베트남의 항만들중 하이퐁항을 선택하여 재무분석 및 그에 근거한 진출전략을 제시하고자 하였다. 재무분석의 결과 기본조건하에서는 재무적 타당성이 있는 것으로 식별되었으며, 민감도 분석에서도 투자타당성은 유지되는 것으로 나타났다. 즉, 건설비의 20% 증가시 처리실적이 30%이상 감소하지 않거나, 건설비의 40%증가시 처리실적이 20%이상 감소하지 않고, 심지어 건설비의 60%증가시 처리실적이 10%이상 감소하지 않는다면 여전히 투자타당성은 유지되는 것으로 식별되었다. 그러나 베트남은 사회주의 국가들 중의 하나이므로 하이퐁항의 투자시 전략적 접근이 필요한 상황이다. 주요사항은 베트남 정부와의 장기적 우호관계 유지, 유력한 현지 파트너의 선정, 철저한 계약관계 형성, 이종문화에 대한 이해 등을 들 수 있다. Vietnam is one of the most economically promising countries in Southeast Asia. This study aims at suggesting the entry strategies for the Vietnamese port development on the basis of the financial analysis. For the purpose of the study, first, the Vietnamese port industry is briefly introduced and the best port to invest is revealed. Second, the financial analysis is conducted on Hai Phong, selected as the best port for investment. Positive results are found in the basic conditions for the port development. Its results also indicate that the financial validity will be maintained when the construction cost increases up to 60 percent and that the financial validity will still be maintained when the construction cost increases up to 100 percent provided that containerised cargoes increase by about 20 percent. This study also suggests strategies for future development and significant issues for investors. It is supposed that the actual investment in the Hai Phong port development will be fairly acceptable in terms of the rapidly developing Vietnamese economy and the significantly increasing economic exchange between Korea and Vietnam.

Single and 4 weeks oral administration of New wonbangwoohwangchungsimwon (NSCH) which was used l-muscone as substitutive material of musk, to beagle dogs of both sexes were performed to investigate both acute and subacute toxicity. Beagle dogs (3 males and 3 females) in acute experiments were administered orally with sinlge dose of 2,000 ㎎/㎏ and groups of 9 male and 9 female beagle dogs in subacute experiments were given daily different dosage of NSCH, 160 ㎎/㎏/day (low dosage group), 400 ㎎/㎏/day (middle dosage group), 1,000 ㎎/㎏/day (high dosage group) once a day for 4 weeks by oral route according to the Established Regulation of Korea Food and Drug Administration (1996. 4. 16). LD_50 value for beagle dogs was more than 2,000 ㎎/㎏ per oral for both male and females. In animals administered with NSCH, there were neither dead animals nor significant changes of body weights. In addition, no differences were found between control and treated groups in clinical sign, urinalysis, eye examination, hematology, serum chemistry, organ weight and other fingings. No histological lesions were observed in both control and treatment groups. Above data strongly suggset that NSCH in beagle dogs is considered to be safe.

Free flaps have been widely used in lower leg reconstruction. However, in cases with extensive injury to the vessels as well as to the bone and soft tissues, and having only one intact major vessel in the lower leg(single vessel leg), careful selection of recipient vessels for the free flap transfer is mandatory for preventing further vascular compromise of the distal lower leg. The sural artery and its vena comitantes are frequently protected form externally harmful forces by the bulky surrounding gastrocnemius muscle and can be used as recipient vessles for free flaps without any detrimental influence on the vascularity of the distal lower leg. In our department, three latissimus dorsi muscle free flap were transferred with sural vessels as recipient vessels in the reconstruction of the single vessel legs. Except for one case of flap failure due to serious infection at the microvascular anastomoses site, all the other cases were successfully reconstructed without any necrosis of the gastrocnemius muscle or the distal leg. In addition, the sural vessels were easily accessed in any patient position and their caliber was similar to that of the vascular pedicles of the donor muscle flaps. In conclusion, the sural vessels can be another useful option in selecting recipient vessels for free flap transfer in the reconstruction of the single vessel leg.

Objectives : The purpose of this study was to investigate the changes of cognitive dysfunctions in patients with Obsessive-compulsive disorder (OCD) over the two-year of pharmacological treatment. Methods : The thirty-three OCD patients and thirteen normal subjects were administered the neuropsychological tests and clinical evaluations twice (at the baseline and two-year). Results : In spite of the two-year treatment, the accuracy of delayed recall on the Rey-Osterrieth Complex Figure Tests (RCFT), the numbers of responses on the category and letter test of Controlled Oral Word Association Test (COWA), the response time on the Trail Making Test part A (TMT-A) remained significantly impaired in the OCD patients compared with the normal controls. Conclusion : These findings suggest that the cognitive dysfunctions such as visuospatial memory and verbal fluency might be the underlying persisting neuropathophysiology of OCD.
