김상열,박성태,서종호,황정동,배현경,오명규 한국작물학회 2017 한국작물학회지 Vol.62 No.1

Germination characteristics, seedling emergence, and early seedling growth of iron-coated rice seeds, cultivars Daebo and Samdeokbyeo, under different water depths were compared with those of non-coated seeds (control) and the results evaluated to obtain basic information for establishing stable seedlings in direct water seeding. The total germination percentage of the two seed treatments was similar, but iron-coated seeds had slightly faster germination and shorter mean germination time than non-coated seeds. Water absorption rates of iron-coated seeds were lower than that of non-coated seeds during seed germination. The germination percentage of the two iron-coated rice seed cultivars showed a significant decline of 15-22% after one year of storage under natural conditions. The seedling emergence percentage and uniformity of the two rice cultivars were significantly higher in the iron-coated seeds at 1-13 cm water depths but the percentage of floating seedlings was lower in iron-coated seeds than in non-coated seeds. The iron-coated seeds had a high seedling emergence percentage of 91.3-93.3% at all flooding depths whereas the non-coated seeds had a significantly low seedling emergence percentage of 57.7-71.7% at a water depth of 13 cm. Moreover, the shoot dry weight and seedling health score of iron-coated seeds were significantly higher than those of non-coated seeds, while root dry weights were similar in iron-coated and non-coated seeds, regardless of water depth. These results suggest that iron-coated seeds are more appropriate for stable seedling establishment in direct water seeding than are non-coated seeds.

김상열,오성환,최경진,박성태,김정일,여운상,강항원 한국작물학회 2009 Korean journal of crop science Vol.54 No.4

자운영 파종시 입모증진을 위한 기초 자료를 얻고자 수입 및 국내산 자운영 종자의 발아특성을 구명한 결과는 다음과 같다. 1. 수입 자운영 종자의 발아율은 79~95%로 수입 년도 및 수집지역에 따라 달랐다. 2. 종피가 검은색인 종자의 발아율은 녹색인 종자보다 발아율은 낮았으나 종자 활력은 비슷하였다. 3. 크기별로는 종자가 큰 것이 작은 종자보다 발아율은 약간 높았으나 종자활력은 크게 차이가 없어 작은 종자라도 상당한 발아력을 가졌다. 4. 광조건이 암조건보다 발아율이 7~9% 높았으나 통계적인 유의성은 없어 자운영 종자의 발아에 광의 영향은 크게 받지 않았다. 5. 수입자운영 종자는 휴면이 타파된 종자가 수입되기 때문에 상온보관시 1년후에는 발아율이 수입당시 보다 6%가 낮았고, 2년후에는 33~35%나 낮아 수입후 1년이 경과한 종자는 10당 추천 파종량 5 kg/10a 보다 1.1배, 2년 경과한 종자는 추천 파종량의 1.4배를 뿌려야 안전 입모수 확보가 가능할 것으로 사료된다. 6. 국내산 자운영 종자는 수확후 강한 기계적 휴면이 있어 상온에서 휴면이 타파되는데 5~6개월이 소요되기 때문에 중국 수입종자와 달리 상온에서 수확후 2년 3개월이 경과하여도 발아율이 72~82%로 수확 후 1년 3개월이 경과한 종자 발아율(73~85%)과 비슷하였다. 따라서 국내생산 자운영 종자의 경우 2년 3개월이 경과한 종자라도 10당 추천 파종량 5 kg/10a을 뿌리면 안전 입모수 확보가 가능할 것으로 사료된다. Germination characteristics of Chinese milk vetch(CMV) seeds produced from Hanam Province, China and Milyang, Korea were investigated to give basic information on the stability of seedling establishment in the CMV cultivation. The germination percentage of the imported CMV seed from China varied according to importation year and seed collection site ranging from 79~95%. The germination of black colored seed coat was lower than the light green colored ones and germination by seed weight was not significantly different. Although the seed germination was lower under dark than in the presence of light, it was not significantly different. The germination of the imported CMV seed slightly declined to only less than 6% after one-year of storage under natural environment conditions but it significantly decreased after two years. However, when the seed was stored at the 5~circC , the seed germination was the same as after two years of storage. On the other hand, fresh CMV seed produced in Milyang, Korea had only 8% germination due to seed coat dormancy but the germination increased to 73~85% after breaking seed dormancy after a year of storage. The high germination percentage of 72~82% was still maintained even after 27 months of seed storage unlike the CMV seed produced from China. These results indicate that CMV seeds do not require light for germination and the seed from China should be used within one-year after importation while the seeds produced from Korea can be used even after two years from harvest for stable CMV seedling establishment in the CMV-rice cropping system.

氣泡塔內의 가스홀드엎에 관한 硏究 : 無機鹽水溶液, 물 -알코올混合溶液과 물-알코올-無機鹽 및 無機酸 三成分 混合溶液을 中心으로 Specially on inorganic electrolyte solution, water-alcohol binary solution, and three components of water-alcohol-inorganic electrolytes

金相烈 東亞大學校 1980 東亞論叢 Vol.17 No.2

氣泡塔 內에서의 가스홀드엎을 無機鹽水溶液, 물알코올混合溶液과 물-알코올-無機鹽 및 無機酸 三成分 混合溶液을 中心으로 溶液의 物性과 分散板의 幾何學的 變化에 따라 調査하였으며 그 結果는 다음과 같다. 1. 分散板의 孔徑과 面積比가 작을수록 가스홀드엎은 커진다. 2. 非吸濕性 無機鹽水溶液의 경우 σf가 클수록 가스홀드엎이 增加하나 吸濕性 水溶液의 경우에는 이 값이 減少할수록 가스홀드엎은 增加한다. 또한 물-알코올-무기산 및 無機鹽溶液의 경우 30∼50Wt.% 濃度에서는 σf의 增加에 따라 가스홀드엎은 커지나 70∼90Wt.%에서는 이 값의 증가에 따라 가스홀드엎의 減少한다. 3. 가스홀드엎에 대한 粘度의 영향은 非吸濕性 水溶液의 경우 σf의의 영향과 類似하며 吸濕性 水溶液의 경우에는 0.9∼1.1cp에서만 가스홀드엎에 영향을 미친다. 또한 물-알코올 無機鹽 및 無機酸 溶液의 경우는 粘度의 增加에 따라 가스홀드엎이 커지다가 어느 限度 以上에서는 다시 減少한다. 4. 物理的 파라미러들과 가스홀드엎 사이에는 다음과 같은 關係式이 成立한다. .???????? Gas holdup of the bubble group was studied on several aqueous solutions of inorganic electrolytes, hygroscopic salts, and alcohols, and three components mixture solution of water-alcohol-inorganic electrolytes for the various geometrical types of distributor. The results were as follows; 1. The effect of the geometrical type of distributor to the gas holdup was inversely proportional to the ratio of hole area of perforated plate. 2. The product of surface tension, (σ) and activity coefficient, (f) was proportional to the gas holdup under fast velocity of distributed air and at slow velocity there was no relation between them, but in the solution of hygroscopic salts, the effect of σf on the gas holdup was inverse. And in the three components solution, particularly, the gas holdup increases with σf in 30∼50% aqueous alcohol, but decreases with σf 70∼90% aqueous alcohol. 3. The effect on the gas holdup with a change of viscosity of solutions was resemble to that of σf in hygroscopic salt, and was valid only in the range of 0.9 to 1.1 cp in hygroscopic salt. But there was a maximum value of gas holdup in the aqueous alcohol and three components mixture solutions of water-alcohol-inorganic electrolytes. This phenomenon was remarkably appeared in a isomeric and higher alcohol. 4. The correlation among the gas holdup and physical parameters was formulated from experimental data as follows; ?????

김상열,김동진,류동근,류용주 한국항해항만학회 2011 한국항해항만학회지 Vol.35 No.7

In this paper, practical problems for current feeder service between Busan port and west coast of Japan were extracted through in depth interviews with Japanese feeder vessel companies, shippers, and port authority based upon which major criteria (elements) for improvement of the feeder network are structured in hierarchic order and weighed relative importance through AHP method. From the questionnaire answered by Korean and Japanese port users and experts the weights of criteria were calculated and the shipping service was ranked the first by both parties with 0.235 and 0.217, respectively. The port service and support system ranked the second and the third, whereas the port marketing was shown to be the lowest of all. Considering the overall weights, the increase in a port loading and unloading speed of port service was followed by provision of dedicated deck for feeder vessel of port facilities for Korean respondents. Therefore, speed up of the port operations and providing docks for feeder vessel are to be firstly provided for more efficient feeder operations, which would be the basis for the construction of optimal transportation network.

金相烈,金瀅翰,睦演洙 동아대학교 공과대학 부설 한국자원개발연구소 1988 硏究報告 Vol.12 No.1

The bubble behavior in a bubble column was observed, and its size and velocity were determined using two sets of probes measuring the resistance. From the measurement a local gas holdup was also obtained. Since the local gas holdup could be measured, the distribution of bubbles in the radial direction was able to find from the experiment. As a result, a correlation between gas holdup and the operating condition of the column, represented as Reynolds number, and the physical property, expressed as Galilei number, was made from the experimental data.

김상열,이재관,장범석,엄흥식 대한치주과학회 2014 Journal of Periodontal & Implant Science Vol.44 No.2

Purpose: The purpose of this retrospective study was to evaluate the effect of patientcompliance with supportive periodontal therapy (SPT) on tooth loss in Korean adults. Methods: The periodontal records of 134 patients were reviewed for this study. They completedactive periodontal treatment from 1999 to 2001 and were placed on a schedule ofperiodic follow-up visits for SPT. Patient compliance was classified into complete compliance(CC), erratic compliance (EC), and noncompliance (NC) groups. Re-examinations werecarried out 11.0±0.8 years after the active periodontal treatment. The prognosis for eachtooth was determined as good, questionable, or hopeless according to the bone loss observedin pretreatment radiographs. Results: The rate of tooth loss of the CC group was significantly lower than that of the NCgroup. The tooth loss/patient and the tooth loss/patient/year were not significantly differentbetween the three groups. The rates of tooth loss in the good, questionable, and hopelessprognosis groups were 6.7%, 9.5%, and 13.2%, respectively. For the teeth with a goodprognosis, the rate of tooth loss of the CC group was significantly lower than that of theNC group (0.4% vs. 5.1%). For the teeth with a questionable prognosis, the CC groupshowed a significantly lower rate of tooth loss than did the EC group (4.1% vs. 30.7%) orthe NC group (4.1% vs. 25.6%). For the teeth with a hopeless prognosis, the rates of toothloss were not significantly different among the three groups. Conclusions: Within the limits of this study, the patients who showed a poor compliancewith SPT were more likely to lose teeth than were the regularly compliant patients. However,the risk of tooth loss with a hopeless prognosis was high irrespective of the compliance.

Distribution Channel Performance Measurement: Valid Measures From Customers' Perspective

김상열 한국항해항만학회 2008 한국항해항만학회지 Vol.32 No.2

This paper is structured into thre main parts and a conclusion. The main section provide definitions of efficiency, effectivenessand performance in terms of the distribution channel, followed by a review of related performance measurement, before discussing difficulties of measurement. According to the theoretical approach, it appears that key theoretical issues are centered around customer service, logistics excellence, time compression, the use of IT, and a move towards integrated logistics. The empirical approach shows that in the past, various financial performance indicators were regarded as relevant management information. However, today, management needs additional performance indicators. Therefore, external assessments of effectiveness must be performed to measure customers’satisfaction with the physical flow of product through the distribution channel network. So, what is needed is to take previous normative and explorative research and progress through a framework by developing valid measures of distribution chanel’s effectiveness and efficiency, and identifying research methodologies suited to the data colection requirements.
