We experimented to see if the tolerance of Agaricus bisporus to Pseudomonas sp. causing the bacterial brown blotch disease which is causing great damage in the button mushroom cultivation was inherited. There was no correlation between mycelial growth rate and mushroom tolerance to pathogens at each temperature. In the mycelial stage, the strains tolerance to Pseudomonas sp. were not as strong as those of their parents, but they were generally stronger or more tolerance than those of weaker strain (ASI1321). In fruiting body, tolerance was decreased compared to mycelial. In fruiting body, later generations of two strains had similar tolerance, unlike strong or weak tolerance of parental generation. Therefore, browning of fruit body is thought to be caused not only by tolerance but also by various other factors. Especially, the future generation of the strains which were tolerance to Pseudomonas sp. were very weak in the mycelial stage, indicating that the tolerance of the parental generation was inherited to the later generations. The damage of each pathogen was different in mycelium and fruiting body. P. tolaasii caused higher browning than P. agarici in fruit body. P. reactans did not have a significant effect on the mycelium but affected the browning of the fruit bodies. P. agarici had higher mycelial growth inhibitory ability than fruiting body.

Timing, place, and the high-tech industry to overcome barriers to the introduct of the so-called “smart agriculture”. The core factors of precision agriculture, including temperature, humidity, location information, and real summary information, are all significant for ICT controlling technique. The system is a four-season container allowing mushroom product, humidity, illumination, and factors such as carbon dioxide were regulated to create the optimal environment for mushroom cultivation. Hericium erinaceum (also called Lion's Mane Mushroom, Bearded Tooth Mushroom, or Bearded Tooth Fungus) is an edible and medicinal mushroom in the tooth fungus group. During approximately 40 days of incubation, 1.4 kg of oak sawdust was used as the test medium. The humidity, temperature, and CO2 density were maintained at >85–95%, 18–20oC, and 700–1,000 ppm, respectively, in the container type culture system. The time for primordium formation was observed to be 4–7 days. The amount of fruitbody production was 74–95 g per bag. This technique will be used to establish a new community support program, in conjunction with international movement, domestic sales and exports are also planned.

When L. ingenua was captured in a low density of less than 400 flies per sticky trap (25x15cm), yellow color trap is the most excellent, and pink color trap is the lowest. The other colors also have attraction abilities. On the other hands, when total mushroom flies are captured more than 1,000 flies, the attraction difference by the trap color has not been confirmed. Therefore, the use of yellow sticky trap was recommended for insect monitoring of L. ingenua and M. tamilnaduensis. 38.1% of L. ingenua and 31.7% of M. tamilnaduensis were attracted to the black light lamp. We confirmed that black fluorescent lamp(BL) will be effective material to attract two dominant mushroom fly at house(≒70㎡). The treatment of one device that is mushroom fly capturing device built-in black light fluorescent lamp decreases 67.8% of mushroom fly. And the treatment of two device decrease 90.4% of mushroom fly. When black fluorescent light lamp for capturing of mushroom fly only turned on during mushroom production room, Gonji-7ho and Heuktari grew up normally in all treatment. But yield of Chunchu-2ho was decreased 34.6% due to the lack of the amount of light in the treatment of black fluorescent light lamp to 100cm from mushroom medium.

White button mushroom (Agaricus bisporus) is the most widely consumed mushroom in the world, and domestic consumption is increasing owing to expansion of the westernized diet in recent years. Before 2000, most Korean mushroom farmers cultivated foreign varieties, but recently, Korean breeders are developing hybrid strains using molecular breeding tools. To produce a better mushroom cultivar, we evaluated some traits of button mushroom Agaricus bisporus strains. Mycelial growth rate at different culture temperatures was investigated by 25>20>15>30>10oC. Recently developed domestic varieties had superior mycelial growth rate compared to the traditionally grown species. In particular, the ASI1338 strain showed excellent mycelial growth rate at different temperatures. Further, we confirmed that ASI1007, ASI1085, ASI1310, ASI1339 were strongly resistant to bacterial brown blotch, whereas ASI1053, ASI1103, ASI1140, ASI1146, ASI1177, ASI1183, ASI1195, ASI1321, ASI1331, ASI1336 were relatively weakly resistant. The average number of days for 16.5, and that for harvest was 5.7; the average yield was 142.7 g/2-kg bag. Mycelial growth rates at 10, 15, 20, 25oC were similar, but that at 30? was lower. The mushroom yield was highly correlated with the number of days for pinheading and harvest.

This study was carried out to determine the basic mycelial culture conditions for Poria cocos growth. According to colony diameter and mycelial density, suitable media for mycelial growth were Malt yeast extract, Potato dextrose agar, Yeast extract agar, and Yeast malt agar. The optimum temperature for mycelial growth was between 25 and 35oC, and the optimum pH value was between 4 and 7. Carbon and nitrogen sources were fructose and yeast extract. The optimum C/N ratio was about 10 to 1 with 2% glucose. Other minor components for optimal growth were thiamine-HCl and nicotinamide as vitamins, acetic and lactic acid as organic acids, and MgSO4·7H2O and FeSO4·7H2O as mineral salts.

This dissertation showcase study of production planning software development for Small and Medium sized Business (SMB). Currently, most of the domestic SMB’s production planning is being established by experienced manager’s intuition. Therefore, the production planning is usually managed by hand written data or established by impromptu process based on years of experience. Under such circumstances, production planning tends to be change frequently and, as a result, it is hard to meet On Time Delivery or to make Capable to Promise that customer asked for when they make order. This dissertation depicts the effectiveness of establishing specific production planning by applying software based on the project which had been implemented for an water tank manufacturing company, Z. The production planning by applying software which is presented in this research, enhanced work efficiency by making possible to share production information between marketing and production managing teams or within team members based on reliable planning. In addition to this, it made possible to have more orders from customers by presenting Capable to Promise schedule.

Korean logistics industry have been focused on transportation business. However, with the expansion of the electronic commerce and on-line shopping, delivery service is now dramatically growing. Despite the expansion of logistics market, the domestic logistics industry have significant structural problems such as low productivity comparing with the advanced countries, relatively high cost and shortage of human resources and lack of professionalism of people in the industry. Logistics companies reallocate employees, use subcontractors, expand consignment and training the employees to overcome the labor shortages but it has some limits. In recognition of the importance of labor in the logistics industry, financial support and investment have increased. Logistics companies tend to hire consultants, set up logistics department or R&D center in order to establish highly productive logistics process and system so it is viewed that there will be considerable demands of human resources in the logistics industry. This study indicates implications and development direction of human resources in the logistics industry by looking into prospect and characteristic of the industry, employment status, training programs and qualification requirements.

앞으로 다가올 자원고갈 사회를 대비하기 위한 국내 정책으로 폐기물의 발생을 억제하고 발생된 폐기물을 적정하게 재활용, 회수, 처리하는 자원순환사회의 형성을 목표로 하고 있으며, 폐기물로부터 에너지를 회수하는 방안에 관한 연구가 적극적으로 진행되고 있다. 폐기물의 에너지화 기술 중에서 폐기물 가스화 공정은 폐기물의 열적처리 공정 중 하나로서 H2와 CO로 이루어진 합성가스를 생산하는 기술로 단순소각을 통한 열에너지의 회수가 아닌 청정연료로의 전환을 통해 고부가가치 에너지원으로 활용이 가능하다는 장점이 있어 높은 관심을 받고 있다. 그러나 가스화 공정에 의해 배출되는 바닥재는 공정특성상 소각공정을 통해 배출되는 바닥재에 비해 미연분 수치가 높게 나타난다. 이러한 미연분 함량은 폐기물관리법 시행규칙에서 강열감량 수치로 규정하고 있다. 본 연구에서는 비성형 SRF(Solid Refuse Fuel)를 활용한 Pilot scale 가스화 공정을 통해 배출된 바닥재의 재활용 방안을 마련하기 위해 강열감량 및 기초특성분석을 진행하였다. 재활용 방안으로 Lab scale의 고정층 가스화 공정을 적용하였다. 바닥재는 800 ℃에서 분당 10g씩 투입되었으며, 공기비 조건에 변화를 주어 생성된 합성가스의 특성분석을 진행하여 바닥재의 에너지회수 가능성을 알아보았다. 또한, 최종으로 배출된 바닥재의 감열감량을 측정하여 최적 감량조건을 도출하였다.

There have been a lot of efforts to increase recycling rate by more utilization of end of life vehicles (ELVs) in Korea.The target of recycling rate was set to 85% until 2014 and 95% after 2015 with including up to 10% of energy recovery,according to the law of “regulation about resource recycling of electrical and electronic products and automobiles”.Therefore, to achieve 95% of recycling rate by the year of 2015, the automobile and recycling industries should developan innovative technology to treat automobile shredder residues (ASRs) by efficient means of reduction or conversion toenergy, which were generated as final left-over after recovering all the valuables from ELVs. As one of the options toconvert to energy forms, the gasification of them was proposed. In this study the gasification experiment was performedusing ASRs at fixed-bed reactor with a capacity of 1kg/hr, at different temperatures of 800, 1,000 and 1,200oC, and atequivalence air ratios ranging from 0.1 to 0.5. The syngas (H2+CO) yield from ASR gasification experiment was obtainedup to 86% in maximum and about 40% in minimum in the experimental conditions given. There was a trend that theamount of syngas increased with elevated temperatures and the calorific value also showed similar trend with syngasproduction.

Recently, the recycling of end-of-life vehicles is becoming increasingly interesting for less waste discharge and recovering useful materials such as valuable metals. Hence, in Korea, the target of the recycling rate is made to 85% until 2014 (energy recovery within 5%) and the recycling rate to 95% after 2015 (energy recovery within 10%) according to the law of "regulation about resource recycling of electrical and electronic products and automobiles". However, the recycling rate is around 84% in 2010, and registered numbers of shredder residue recyclers among dismantling recyclers, crushing recyclers, shredder residue recyclers, and waste gases recyclers are very few. In order to meet the goal of 85% until 2014, Korean recycling industry of ASR should grow bigger and innovative recycling technologies have to be developed as well. In the meantime, a recycling technology of automobile shredder residue is developed in the present study, in which ASR is introduced to a copper smelting process. This process is very promising because of co-beneficial effects such as recovering copper and process heat simultaneously from ASR. In this study, lab-scale melting furnace was developed and melting tests for various ASR were carried out. From the results, the physicochemical characteristics of Korean ASR were analyzed and its melting behavior was investigated for the application to the copper smelting process. In particular, melted slag products were fabricated at different melting temperatures. Then, the basicity and pouring index in the lab-scale melting furnace were examined to find out appropriate operating conditions for the melting process. As a result, Because the amount of lump coal that included in existing process samples is a little, melting state and value of pouring index are very similar to existing process samples. In result of this experiment, in case of changing lump coal to ASR, The existing copper smelting facilities, if basicity and melting temperature are well controlled, flow of melting material is considered that is almost not affected.
