윤세영,Yun, Sei-Young 한국토양비료학회 1992 한국토양비료학회지 Vol.25 No.1

유기물(有機物)의 시용(施用)이 고추역병의 발생에 미치는 영향을 조사하기 위하여 폿트시험을 수행하여 다음과 같은 결과를 얻었다. 1. 고추역병의 억지에 대한 유기물시용의 효과는 기온이 높은 여름보다는 가을시용이 효과적이었다. 또, 유기물의 종류별(種類別)로는 퇴비류(堆肥類)보다는 신선유기물(新鮮有機物)인 볏짚의 시용효과가 컸다. 2. 토양미생물상(土壤微生物相)에 대한 유기물시용(有機物施用)의 영향(影響)은 특히 볏짚시용에서 가장 커서 사상균(絲狀菌) 및 세균수(細菌數)의 증가가 현저하였다. 3. 가을 1작기(作期)의 토양의 고추 역병균(疫病菌) 조사결과 유기물 무시용구 및 퇴비류 시용구에서는 고추재배 초기에는 역병균을 분리할 수 없었으나 시기가 경과함에 따라서 역병균이 검출되었다. 볏짚 시용구에서는 재배 초기에는 역병균이 검출되었으나 재배중기 이후에는 검출되지 않았다. 이러한 현상은 볏짚과 퇴비류가 토양중 역병균의 생존에 미치는 영향이 다른데에 기인하는 것으로 생각되었다. 4. 각 처리구의 사상균을 분리 동정한 결과 시용한 유기물의 종류에 따라 현저한 차이가 인정되었다. 5. 볏짚시용구의 전사상균수(全絲狀菌數)에 대한 길항사상균수(拮抗絲狀菌數)의 비율은 다른 처리구에 비하여 매우 높은 것으로 나타났다. Results as follows are obtained from the pot experiment to examine effect of application of organic substances on inhibition of occurrence of root rot of red pepper. 1. As for effects of applicating organic materials on inhibition of red pepper root rot, it is more effective to apply in autumn than to apply in summer, when the temperature is high. In addition, organic substance which is not decomposed completely such as rice straw is more effective than matured compost types. As for effects of applicating organic substances on composition of soil microorganisms, increase of fungi and bacteria in view of numbers is remarkable, especially in case of applying rice straw. 2. From the examination of Phytophthora capsici in soil at the 1st cultivation period in autumn, no P. capsici can be isolated in early stage of growth of red pepper in nontreated soil and in soil applied compost. However, as the time goes on, P. capsici are detected. While in early stage of cultivation, P. capsici are detected in soil applied with rice straw, P. capsici are not isolated after middle stage of cultivation. 3. It is recognized that there are many differences according to the types of organic materials applied in the result of identification of fungi in each treatment. And, proportion of antagonistic fungi to total fungi in soil applied rice straw is proved to be significantly higher compared to other treatments.

A series of laboratory experiment was conducted to find out the effects of physico-chemical, microbiological and commercial inhibitors on the odorous gas evolution in the fermentation of livestock feces. The results obtained were summarized as follows. 1. The rate and amount of evolution of gas were the highest at 7 days after incubation, thereafter gradually decreased until 24 days after incubation. 2. The rate and amount of gases were evolved in order of $CO_2>N_2O>CH_4>NH_3>N_2S$, respectively. 3. The highest amount of methane gas was evolved from the poultry feces, those of carbon dioxide and nitrous oxide were evolved from the pig feces, and that of hydrogen sulfide was dominantly evolved from the cattle feces. 4. Negative correlation were obtained between the total amounts of $NH_3$ and $CH_4$, $CO_2$ and $CH_4$, $N_2O$ and $CH_4$, $N_2O$ and $CH_4$, while positive correlations were obtained between the amounts of $CO_2$ and $N_2O$, $CO_2$ and $NH_3$, and $NH_3$ and $N_2O$, respectively. 5. There was no significantly inhibiting effect obtained that the application of commercial gas inhibitor as VK 88. On the other hand there was significantly inhibiting effect obtained when application of fertile paddy soil and photosynthetic bacteria to the fermentation of livestock feces. 계분(鷄糞), 우분(牛糞), 돈분(豚糞)등의 가축분뇨(家畜糞尿)가 발효(醱酵)시 발생(發生)되는 악취(惡臭)가스에 대한 이화학적(理化學的), 생물학적(生物學的) 억제효과 및 시판(市販) 악취억제제(惡臭抑制劑)의 시용효과에 대한 실내시험결과(室內試驗結果)를 요약(要約)하면 다음과 같다. 1. 항온기간중(恒溫期間中) 각종(各種)가스의 경시적(輕時的) 발생량(發生量)은 항온(恒溫) 7일경 가장높은 발생량(發生量)을 보였으며 그후는 점차 감소(減少)되었다. 2. 혐기적발효(嫌氣的醱酵)에 의한 가스의 총발생량(總發生量)은 이산화탄소(二酸化炭素)($CO_2$)>아산화질소(亞酸化窒素)($N_2O$)>메-탄($CH_4$)>암모니아($NH_3$)>황화수소(黃化水素)($H_2S$)의 순(順)으로 많았다. 3. 가축분(家畜糞) 종류별(種類別) 가스 생성량(生成量)을 보면 계분(鷄糞)에서 메-탄, 돈분(豚糞)에서 이산화탄소(二酸化炭素) 및 아산화질소(亞酸化窒素), 그리고 우분(牛糞)에서 황화수소(黃化水素)가스의 발생량(發生量)이 많았다. 4. 각종(各種)가스 발생량간(發生量間)의 상관관계(相關關係)를 보면 $NH_3$ 와 $CH_4$, $CO_2$와 $CH_4$, $N_2O$와 $CH_4$는 부상관관계(負相關關係)를 보였고 $CO_2$와 $N_2O$, $CO_2$와 $NH_3$ 및 $NH_3$ 와 $N_2O$ 간(間)에는 정상관관계(正相關關係)를 보였다. 5. 농가(農家)에 유통(流通)되는 악취(惡臭) 억제제(抑制劑)인 VK88은 암모니아의 발생(發生)을 오히려 증가(增加)시켰으며 황화수소(黃化水素) 발생(發生)을 억제(抑制)시키는 효과가 있었으나 현저(顯著)한 효과는 아니었으며 VK88은 Vermiculite와 유사(類似)한 결과(結果)를 보였다. 6. 자연계(自然界)의 논토양(土壤)과 광합성세균(光合成細菌)의 첨가(添加)는 암모니아, 아산화질소(亞酸化窒素)및 황화수소(黃化水素)의 발생억제(發生抑制) 효과가 뚜렷하였다.

Effects of Decomposition of Organic Substances as Rice Straw and Chicken Manure mixed with Saw Dust treated with Commercial Inoculums

윤세영,이용환,Yun, Sei-Young,Lee, Yong-Hwan 한국토양비료학회 2000 한국토양비료학회지 Vol.33 No.4

These experiments have been conducted to study the effect by microbial inoculums currently on the market of enhancing the decomposition of organic matters. As a result of studying the effect of enhancing the decomposition of rice straw and chicken manure mixed with saw dust treated with commercial inoculums, it was found that the use of inoculums have speeded up the rate of decomposing straws at the early stage. The decomposition rate of rice straws that have speeded up with the use of comcrial inoculums in at early incubation periods has slow down in the later stage while the decomposition rate of chicken manure that has slowed down in the early stage has speeded up at the later incubation. As a result, it is found that there have been no differences between the use of microbial inoculums and control. In the experiment, filamentous fungus is found to have played an important role in decomposing the rice straws and bacteria is considered to have played a greater role in the decomposition of chicken manure mixed with saw dust. 미생물제의 퇴비부숙효과를 검토하기 위하여 국내에 유통되고있는 Lacto외 4종 미생물제에 대한 퇴비부숙 촉진 효과를 보면 볏짚에서는 락토 및 천보, 생력등 일부 미생물(微生物)제의 처리에 의하여 초기에 부숙촉진경향이 관찰되었으나 초기에 부숙이 촉진되었던 처리는 후기에 부숙속도가 늦어지고 초기에 부숙속도가 늦었던 처리는 후기에 부숙속도가 빨라짐으로서 결국 미생물제처리 40일경에는 미생물제 사이에 뚜렷한 차이가 인정되지 않았다. 또한 미생물제를 시용하면 볏짚부숙중에 사상균수의 증가가 현저하였으며 볏짚의 부숙과 사상균수의 변동과 일치하는 경향을 보였으나, 계분톱밥부숙에 미치는 미생물제의 영향을 보면 퇴적초기에는 세균, 방선균, 사상균 모두 균수가 극히 적었으며 세균수만이 시간이 경과함에 따라 균수의 증가가 현저한 점으로 미루어 볼 때 세균이 계분톱밥퇴비의 부숙에 밀접한 관련이 있는 것으로 판단되었다.

미생물제 비료시용이 배추의 생육과 토양 화학성 및 미생물상에 미치는 영향

윤세영,신중두,Yun, Sei-Young,Shin, Joung-Du 한국토양비료학회 2001 한국토양비료학회지 Vol.34 No.1

미생물제 비료시용이 배추의 생육과 토양의 화학성 변화 및 미생물상에 미치는 영향을 포장시험으로 실시하였다. 대조구에 비하여 TLB미생물제 비료를 시용함으로써 배추의 생육은 양호하였으며, 배추수량에 있어서도 유의성 있는 증수 효과를 보였다. 그러나 TLB미생물제 비료를 시용하더라도 배추생육시 요소비료의 추비량 및 퇴비 시용량을 줄일 경우에는 대조구에 비하여 수량이 다소 감소하는 경향을 보였다. 토양의 화학적 성질에 미치는 TLB 미생물제 비료 시용의 효과는 대조구에 비하여 수확기의 토양유기물 함량의 감소가 가장 큰 것으로 나타났고, 토양중 전질소 함량은 0.76~1.44% 범위로 대조구보다 오히려 미생물제 비료 시용구가 감소하는 경향을 보였다. 토양중 유효인산 함량은 시험전 토양의 559ppm에 비하여 배추의 수확기에 대조구 755ppm 그리고 미생물제 시용구 653ppm으로 대조구와 비교하여 미생물제 시용으로 인하여 다소 낮은 편이었다. 한편 배추 수확 후 배추의 화학적 성분은 전 질소 2.62~2.94%, 인산 1.48~1.55%, 칼리 3.60~4.38%범위이었으며, 각 처리간에 함량의 뚜렷한 차이는 없었다. 토양 미생물상중 전세균수는 대조구보다 미생물제 시용으로 다소 감소하였으나, 배추수확기 토양에서 Pseudomonas속이 3배 이상 높은 군락을 보였다. 그러나 방선균은 큰 차이를 보이지 않았지만, 사상균수는 수확기 토양에서 미생물제 비료 시용으로 현저히 높은 군락을 형성하였다. This experiment was conducted to investigate the effects on plant growth, soil chemical properties and microbial flora with microbial fertilizer to chinese cabbage cultivation. The plant growth was promoted and the yield increased by application of Tian Li Bao(TLB) microbial fertilizer as compared with the control. However, yield a littler decreased in case of the reduced amount of urea application as a top dressing and half of compost chicken manure as a basial fertilizer even if treated with TLB microbial fertilizer. Organic matter and total nitrogen contents decreased as compared to those in the control, and total nitrogen ranged in 0.76~1.44% in the treatments at harvesting time, and decreased with application of TLB microbial fertilizer compared to that of the control. The available phosphorus content in the field before experiment was 559ppm, but it was 755ppm and 653 in the control and treatments at harvesting time, respectively. Therefore, it was shown that phosphorus content in the treatment was lower than that of the control. On the other hand, total nitrogen, phosphorous and K ranged from 2.62 to 2.94%, from 1.48 to 1.55% and from 3.60 to 4.38% in plants after harvest, respectively. There were no significant differences among the treatments. For the soil microbial flora, the population of bacteria in the treatments decreased with application of microbial fertilizer as compared with the control over all cultivation periods. It was shown that the population of pseudomonas spp. was over 3 times higher than that of the control after harvesting. The population of actinomycetes didn't show difference among the treatments, but high density of fungi after harvesting were observed in the treatments.

비행 스케쥴 변동에 강건성을 갖는 주기장 배정 문제의 최적화 해법

윤세영(Seyoung Yun),박성수(Sungsoo Park) 대한산업공학회 2008 대한산업공학회 추계학술대회논문집 Vol.2008 No.11

This paper considers Airport Gate Assignment Problem (AGAP) which is finding an effective gate schedule while satisfying passengers walking distance, space restriction and ground time conditions. The objective of this problem is finding a robust solution which is quite insensitive to variation in flight schedule. Even though the idle time between two consecutive flights is assumed to be uncertain, a solution can be accomplished by the robust combinatorial optimization. In addition, we control the tradeoff between robustness and optimality by introducing a parameter that denotes the protection level for constraints. We formulate this problem as an integer linear program (ILP) using variables corresponding to flight series which can be assigned to a certain gate. To solve this, we develop a branch and price algorithm where an efficient branching rule is adopted. Furthermore, we stabilize the column generation to accelerate a convergence. The pricing problem is solved easily by composing networks for each gate separately. To test the performance of the algorithm, we have tested the algorithm with real flights and gates data provided by Incheon International Airport. Computational results are reported.

고교학점제 연구·선도학교 교사와 학생의 진로·학업 설계 지도 경험에 대한 질적 사례연구

윤세영(Seyoung Yun) 한국교원교육학회 2024 한국교원교육연구 Vol.41 No.1

고교학점제 연구·선도학교가 도입된 후, 교육과정 양적 확대가 이루어지고 있는 한편 학교 현장에서는 학생들의 선택권을 제대로 보장해줄 수 있는지에 대한 가능성과 한계를 중심으로 논란이 가열되고 있다. 진로·학업 설계 지도에 대한 질적 제고가 강조되고 있으나, 선행연구들은 교사와 학생의 경험을 분절적으로 분석하여 문제점이나 대안을 나열하고 있다는 점에서 한계를 갖는다. 따라서 학교 현장의 총체성, 맥락성, 특수성에 따른 진로·학업 설계 지도에 대한 이해가 필요한 실정이다. 이에 본 연구는 질적 사례연구방법을 통해 교사와 학생의 진로· 학업 설계 지도 경험을 구체적으로 탐구하고자 하였다. 연구 결과, 교사와 학생의 진로·학업 설계 지도가 목적대로 실현되는 것을 방해하거나 촉진하는 요인과 시사점을 발견할 수 있었다. 연구 결과를 토대로 교과목 이해와 생애 비전 중심의 잠정적 진로·학업 설계 지도, 학생성장 중심의 모두를 위한 진로·학업 설계 지도, 협력적 문화와 배움에 기반을 둔 관계 중심의 일상적 지도가 필요함을 발견하였다. 이를 현장에 실천하기 위해 교사 조직의 반성적 교사교육의 실천, 관계 전문가로서 교사역할에 대한 공동체적 지지와 더불어 학생 사례를 중심으로 한 연수 방식의 차별화 및 제도적·환경적 변화가 함께 이루어져야 함을 제언하였다. After the introduction of research on the high school credit system and leading schools, the curriculum has been quantitatively expanded, while controversy is heating up centered on possibilities and limitations of whether students' right to choose can be properly guaranteed in the school field. Hence, while a qualitative improvement of career and academic planning guidance is emphasized, previous studies have limitations in that they list problems or alternatives by segmentally analyzing the experiences of teachers and students. Accordingly, there is a need to understand the career and academic planning guidance according to totality, context, and specificity of the school field. Therefore, this study sought to specifically explore the experiences in the career and academic planning guidance of the teachers and students through a qualitative case study method. As a result of the study, it was possible to discover factors and implications which hindered or promoted realization of their career and academic planning guidance as intended. Based on the study results, it was discovered that provisional career and academic planning guidance centered on understanding of the curriculum and life vision, the career and academic planning guidance for everyone centered on growth of the students, and daily guidance centered on a relationship based on cooperative culture and learning were needed. In order to put this into practice in the school field, it is suggested that along with practice of reflective education by the teachers in their organization and community support for the teachers’ role as a relationship expert, differentiation of their training methods centered on the students’ cases and institutional and environmental changes should be made together.

It is of the most importance for us to set up the chronicle of ancient mounds in figuring out the bui1ding period of Three Kingdoms(Silla, Paekch.e, and Kokoorye) tombs. The establishment of tomb chronicle is very indispensab1e in order to grasp and then examine close1y the period of the triangu1ar position of Three Kingdoms. F,ortunate1y, it is possib1e to set up the chronicle of ancient tombs, because Ho-u Tomb represents the clear time. In this treatise, 1 tried to set up the chronicle in the result of researohing the main excavated remains-the crowns, earings, gold bands, and knives-and refering to the chronicle of old Silla to mbs. Ⅰ. The Structure of Ancient Tombs in which Crowns were Found and Those Distributing Spots. The tombs of Old Silla are main1y distributed at Whangnam Dong, Kyo Dong, Rodong Dong, Rose Dong, Pomun Dong, and Whangoh Dong in the Capita1 City of Kyungchoo. The structure of tombs is called Cheksok Mokkwak Pun. The process is the following : The ob1ong grave was vertically dug and a wood case was put into the pit, and the coffin made of wood was 1a仗, and above the wood coffin stream stones were pi1e吐up , and then above stones soi1 was covered. There are two kinds of mound: one mound which contained more the two coffins, the other \vhich contained on1y one coffin. The tombs of Kaya are centra1ized round Rakdong River where Six Kayas ho1d those court,especially Da1sung, Koryung, Changyung, Sung- choo, Sunsan, Eusung, and Yangsan. The structure was classified into three kinds: Stone Case Mound of ertical Orifice Style, Stone Mound of Transversal Style, which belongs to Vertical Orifice, and Stone Mound of Transversal Orifice. Ⅱ. Crowns and Remains Necessary to Research of the Chronicle of Old Mounds. 1. Crowns. A crown consists of an exterior cap, an interior, and another. The forms to overlap the Chinese character (ill, which means a mountain) shape and the form to fix an antler were decorated at the ring of an exterior cap. In the fron t of an interior cap, a bird style and bird fea ther form was formed. The interior of ring, which is touched at head, was added to the cap of barks of birch or of gold silver. The Kaya crown is the same form as the Silla crowns which were originated from the former. 2. Re1ics Indispensable to Research of the Chronic1e of Old Mounds. There are many kinds of reamins. Among those e8rings, bands, and knives are representative works. The earings of Old Si11a and Kaya are together c1assified into three types-plain ring style, thin ring, and thick ring. The gold band, the decoration of leather belt, is formally divided into three kinds (a) plain links are added to the plate of Bochoo (heart form) style, (b) the plate is the form of trileaves, and (c) the oblong plate on which Tangcho letters were ingraved. Large knives are classified into the knife head which is plainly ring, which is formed as trileaves ring, which is three rings, and \yhich is figured as the semi-eIIiptic form. In Old Silla the knife head is de· corated with a single dragon, and with two dragons. Ⅲ. The Relation between the Chronicle of Old Tombs and Relics. 1. The Change of the Structure of Ancient Tombs and the Relation Between Crowns and Remains. In Old Silla the tomb pattern is changed as the following: from the tomb structure of a family grave to a couple with a side coffin, to only couple grave, and then a single coffin grave. Because the Stone Case Mound of Vertical Orifice Style is preceding to the Stone Mound of Transversal Style which belongs to Vertical Orifice, the changing process of crowns, earings, gold bands, and large knives is researched. on the basis of the 59th Mound and 1st Stone Coffin of the 37th Mound in Dalse Myn. 2. The Chronicle of Old Si1la and Kaya Tombs.
