Pine wood nematode (PWN), Bursaphelenchus xylophilus, is a causal organism to induce pine wilt disease (PWD) in many varieties of pine trees. PWD was first introduced to Korea in 1988 but, the damage has been dramatically increased since 2000. Recently PWD is newly reported in Korean pine tree (Pinus koraiensis) and is considered one of the most important forest diseases in Korea. Fifteen isolates of B. xylophilus, 2 isolates of B. mucronatus, and 6 unidentified Bursaphelenchus spp. were collected from different geographical locations and hosts in Korea. All the isolates were cultured in fungal medium and nematodes were harvested for further experiment. First, all the isolates were characterized by both ITS and D2D3 rDNA sequence analysis. Template DNA was prepared by DNA extraction from single female nematode. ITS and D2D3 region were amplified by PCR and followed by cloning and sequence. As a result, all the sequences of ITS and D2D3 from B. xyophilus isolates were identical and there is no intraspecific variation. However, 2 genotypes of B. mucronatus were found, which one from P. thunbergii was East Asian type and the other one from P. koraiensis was European type. ITS-RFLP phenotype was also proposed to discriminate different species and genotypes and 5 enzymes, Hinf I, Alu I, Msp I, Hae III, and Rsa I. were selectively treated.
성인애착과 친밀감에 대한 두려움 간의 관계: 자아분화와 자아존중감의 매개효과

This study analyzed the relationship between adult attachment, self-differentiation, and self-esteem in solving the fear of intimacy in interpersonal relationships experienced by adults. This study targeted people in the 20s to 50s age group, and data from 1,263 participants were analyzed using SPSS 23.0 and AMOS 23.0. The results are as follows. First, it was found that secure attachment had a negative relationship with the fear of intimacy, while the relationship between self-differentiation and self-esteem was positive. On the other hand, anxiety attachment and avoidance attachment were shown to have a positive relationship with the fear of intimacy, but a negative relationship was identified with self-differentiation and self-esteem. Second, it became evident that self-differentiation and self-esteem mediated the relationship between adult attachment and the fear of intimacy. Additionally, the findings indicated that self-differentiation and self-esteem had a dual mediating effect. The results of this study can be used as basic data for counseling and educational programs to solve the fear of intimacy in interpersonal relationships experienced by adults.
사과뿌리썩이선충의 침입과 기주의 해부학적 및 생화학적 변화에 관한 연구
한혜림,한상찬,김용균 한국응용곤충학회 1995 한국응용곤충학회지 Vol.34 No.2
본 연구는 뿌리썩이선충(Pratylenchus vulnus)이 옥수수뿌리조직을 침입했을 때, 조직의 해부학적.생화학적 변화를 밝힘으로써 식물과 선충의 상호관계를 이해하고, 이들 정보를 바탕으로 선충저항성 작물의 육종 및 선별에 활용하기 위함이다. 옥수수뿌리 표피를 뚫고 들어온 선충은 뿌리 피층에 자리를 잡고, 세포벽을 파괴하면서 다른 세포로 이동한다. 마침내 선충들은 피층의 내피와 세근의 기부에 밀집했다. P.vuinus의 암컷들은 세포내에 공간(cavity)을 형성하여 그 속에 알을 낳는 습성을 지니고 있다. 선충에 의한 주된 피해양상은 세포벽이 파괴되고 부서져서 공간을 형성하는 것으로 나타난다. 이러한 현상은 세근의 기부에서도 관찰된다. 선충의 피해로 야기된 옥수수 뿌리의 생화학적 변화는 선충접종구와 무접종구간 총단백질양과 esterase활력조사를 통해 비교.분석되었다. Denaturing gel 상에서 총단백질양의 비교는 유의한 차이를 나타내지 않았고, esterase 의 pattern 및 활력에서도 유의할 만한 차이는 발견되지 않았다. Anatomical and biochemical changes of the corn root injured by the root lesion nematode, Pratylenchus vulnus, were examined to understand the interactions between the nematode and the crop which can be applied to a breeding program for nematode-resistant crop. The nematode and the crop which can be applied to be a breeding program for nematode-resistant crop. The nematode entered the cortex of corn root through its epidemis. They moved to other cortical cells by breaking their cell walls. They, finally, gathered around the endodermis of the roots and the bases of the root hairs. Parasitism of the nematode formed cavities within the root tissues where the females laid eggs. Major root damage by the nematode occurred in the cortical cells where must cell walls were broken and crushed to form empty spaces. These empty spaces in the base of the root resulted in this breakdown. Damage-induced biochemical changes of the corn roots were analysed by their total protein patterns and esterase activities in both control and nematode-infected roots. Denaturing gel did not show any significant difference in the banding patterns between them. Esterase patterns and activities, also, were not significantly different between the infected and the control roots.

Zinc dialkyldithiophosphate(ZDDP)는 엔진 오일의 첨가제로써 산화 방지, 마모 억제 등의 성능과 저렴한 가격으로 인하여 오랫동안 사용되어져 왔다. 이러한 ZDDP의 성능 중 마모 억제를 목적으로 하며, zinc와 같은 금속을 포함하지 않고 dialkyldithiophosphoric acid(DDP)를 포함하는 알칸 디올 유도체를 효율적으로 합성하고, 이에 따른 마찰학적 특성에 대하여 연구하였다. Butanediol을 사용하여 에스테르화하여 bis[methacryloyloxy] butane을 합성한 후, DDP의 알킬 사슬에 변화를 주어 bis[3-(dialkyloxyphosphorothionyl)thio-2-methyl propanyloxy] butane을 합성하고 이에 따른 내 마모 성능을 살펴보았다. 알킬 사슬의 탄소 수가 4, 8, 10일때, 각각의 WSD는 0.595, 0.459, 0.494 mm로 측정되었다. DDP의 알킬 사슬의 탄소수가 4개일 경우 WSD값이 가장 크게 측정되었고, 탄소수가 8개일 경우 가장 적은 값으로 측정되었다. 탄소수가 8개 이상일 경우, WSD값이 서서히 증가하는 것으로 관찰되었다.
