본 연구는 시설토마토 재배지에서 push-pull 전략을 이용해 담배가루이와 천적곤충의 행동을 제어함으로써 담배가루이(Bemisia tabaci)를 친환경적으로 방제하기 위한 기술을 개발하고자 수행하였다. 담배가루이는 노란색에 유인율이 가장 높았으며, 520 nm의 광원에는 유인반응을 복합광원인 450 + 660 nm의 광원에는 회피반응을 보였다. 천적곤충인 담배장님노린재(Cyrtopeltis tenuis)와 미끌애꽃노린재(Orius laevigatus)는 모두 520 nm의 광원에 가장 높은 유인반응을 보였다. 휘발성 물질로는 ocimene과 carvacrol에 대해 기피반응을, methyl isonicotinate에는 유인반응을 보였다. 토마토 온실에 메밀을 투입하였을 경우 천적곤충인 담배장님노린재의 밀도는 무처리 대비 15일간 약 16배로 높게 유지되었다. Push-pull 세부전략들을 종합 처리한 결과, 처리 50일 경과 후 담배가루이의 트랩당 밀도는 무처리 대비 3배 이상 낮게 나타났으며, 이에 따른 시기 별 방제효과는 시간이 경과함에 따라 증가하는 경향을 보인 가운데 최고 68.7%였다.

This study was conducted to develop a technology for environmentally friendly control of Bemisia tabaci by a push-pull strategy in tomato greenhouse. B. tabaci was most attracted to the light source of 520nm, whereas it showed an avoidance response to the complex light treatment of 450+660nm. Two natural enemies, Nesidiocoris tenis and Orius laevigatus were attracted to 520nm. B. tabaci was repellent to volatile organic compounds, ocimene and carvacrol, while methyl isonicotinate showed attractant response. When buckwheat was added into the greenhouse, the density of N. tenis was maintained at about 16 times higher for 15 days. As a result of the combined treatment of push-pull strategy, the density of B. tabaci was 3 times lower and the control effect increased with time and reached up to 68.7%.

The purpose of this study is to improve practical skill evaluation method of mushroom - trained certified technician's practical skill evaluation which is one of national qualification tests based on national incompetency standards. One of the current National Competency Standards (NCS), mushroom - trained certified technician uses NCS based practical assessment method. In order to improve the current practical evaluation method, we try to improve practical evaluation method based on field customized problem solving ability and improve the practical evaluation method, various evaluation methods should be constructed. On the purpose of identify the diversity and problems of the evaluation method, the experts of the group consultation, the mushroom-related research institute and the related industry collaborated to identify the problems of the actual mushroom - trained certified technician practicum test, This study on the evaluation improvement method was carried out. In this study, the contents of practical test of the current mushroom traits were analyzed and the trends of the latest mushroom industry were widely reflected.

This study is investigated the growth characteristics(number of available stipe, pileus diameter, pileus thickness, stipe length, stipe thickness, object weight, comparison yield ability of 1 cycle) and storage characteristics of ‘Sanjo 701’ (S7) cultivars according to relative humidity. The S7 growth characteristics were investigated by quantifying the growth and the characteristics according to the relative humidity, The storage stability was investigated every 5 days and freshness was measured by ‘Minamide Method’. S7 pileus diameter is The higher the relative humidity was confirmed becomes larger and the more increased relative humidity also increase the comparison yield ability of 1 cycle. However, pileus diameter or stipe length This could not see the big difference in the three treatment groups, the plieus thickness was no significant difference in the treatment of 80% and 95%. The fresh weight of S7 decreased significantly at 80% and 95% relative humidity after 10 days of storage, but decreased continuity in 65% humiditiry. The elongation percentage of S7 pileus was observe in 95% relative humidity, values of L, a and b (SCI), showed the highest L value in 65% and the a value in 95%. b values were similar in 65%, 80% and 95% treatments. On the ‘Minamide Method’ measure freshness was changed from the 10th day of storage at relative humidity of 95%, but humidity of 65% and 80% treatments, it changed after 15 days of storage. In this study growth characteristics and yield were increased at higher relative humidity, but storage stability was decreased. Therefore, it is deemed necessary to change the relative humidity to produce high quality mushrooms.

This research was relative humidity (65, 75, 85 and 95%) growth characteristics of the oak mushroom (Lentinula edodes) 'Nongjingo’. At the relative humidity was 65% in growth chamber. On this condition the moisture content of medium surface was 60.5%. That was lower than other treatments. That condition makes Pileus was 77.1% and stipe was 65%. Among the growth characteristics according to the relative humidity, the pileus diameter at 75% relative humidity were 45.5mm that largest than other treatment and pileus thickness at 75% relative humidity were largest than other treatment. The stipe thickness at 65% relative humidity were 14.8mm that lagest than other treatment. The number of available stipes at 95% relative humidity were 13.3peace/2kg that largest than other treatment. The comparison yield ability of 1 cycle was 104.2g that result in largest than other treatment at 95% relative humidity. This result was associated to the relative humidity of fruiting bodies, the lower relative humidity result in the lower of yield. However, the lower relative humidity result in the higher number of whago, Especially, at the treatment of 65% relative humidity, all the fruit bodies were produced as Whago (dry). Therefore, the higher relative humidity influenced in the higher yield but produced water mushroom. That result was thought that ‘Nongjingo’ would be possible to produce high quality mushroom by adjusting the relative humidity appropriately.

Acquisition of relative clauses in Korean and Japanese has been one of the fruitful research topics in the modern linguistics. Kim (1987) and Lee (1991) especially have revealed many interesting aspects of the acquisition of relative clauses, especially the relative clauses in Korean. They claim that so-called externally-headed relative clause constructions are acquired earlier than the internally-headed relative clauses in Korean. Contrary to what Kim (1987) and Lee (1991) claim, Cho (1999, 2003) proposes an alternative such that the internally-head relative clauses (IHRCs) in Korean are acquired earlier than the externally-headed ones (EHRCs). If this is the case, then why? Cho (2003) simply remarks that children tend to acquire structures that are easy to understand earlier than those that are not. We will critically re-examine this claim and provide some explanation. That is, we show that IHRCs are acquired earlier than EHRCs because the former are semantically more transparent than the latter, while having the same syntactic structures.

In this paper, I show that VP-front, some cases of wh-movement, and topicalization all share properties that would be explained by adopting some version of minimal reconstruction proposed in Jang (2000). I show that previos analyses proposed to resolve the issue of binding effects exhibited in VP fronting sentences may not be viable to account for wider range of data. That is Huang (1993) proposes that VP-internal Subject Hypothesis and general binding theory are enough to explain the said phenomena. Takano (1995) proposes that reconstruction, which is independently motivated, is needed to explain the binding phenomena in VP fronting and related constructions. This paper shows that neither analysis, as it is now, can cover relevant data and that some more qualification such as Jang (2000) may be needed to conditions on reconstruction.

Youngjun Jang. 2003. Non-Sentence-Final clauses in English. studies in Mordern Grammar 31, 189-197. In this paper, we argue that an explanation based on feature-checking is not enough and in fact not viable in accounting for the expletive it in the subject position and the object position in English. As an alternative, we propose that a kind of ban on non-snetence-final clauses (first proposed in Kuno 1978) is in operation in constraining the distribution of in the a sentence structure.

Youngjun Jang. 2001. Complementizers and Complementation in English and Korean: Successive Cyclic WH-Movement. Studies in Modern Grammar 25, 1-28. This paper investigates complementizers and complementation in English and Korean. I argue that a sentence is ultimately a projection of C because the clausal types must be present for interpretation and that the clausal typing feature in C must be checked off. It is shown that the superficial difference between English-type languages and Korean-type languages with regard to wh-movement is due to different modes of checking off the clausal typing feature in C. Some theoretical consequences of this proposal are that successive cyclic wh-movement can be naturally accounted for in a derivational approach to syntax and that the strength of C is always strong both in English and Korean-type languages.
