Protective clothing developed for rose flower farmers has been evaluated to improve the working conditions. The requirements of rose farmers were first identified to design protective clothing for farmers working with thorny plants. A fit test was conducted to assess the thermal comfort and protective function against thorn pricking to compare and evaluate the usability of developed experimental clothing with existing working clothes. Based on the survey results of rose farmers' requirements, protective clothing was designed in the form of an apron (which was the most preferred after gloves) with a pattern designed for the production of experimental clothing. For the developed protective clothing, the strap and buckle closure method was selected to open the back of the body as much as possible; in addition, sleeves were made in the attachable form of a half-sleeve to protect the arms from the thorns. The fit test of the developed protective clothing and existing working clothes revealed the temperature and humidity inside the developed protective clothing to be significantly different in the back compared to existing work clothes. In addition to thermal sensations, the subjective humidity sensations were statistically significant different in the developed protective clothing compared to existing work clothes. The subjective protective function for thorn pricking was also found to be satisfactory.

관통성 손상 후 외부 이물질이 신체 조직 내 남아 있는 경우는 응급실을 방문하는 주요 원인 중의 하나이다. 수부에서 발견되는 이물질은 대부분 외상에 의해 발생하며 식물성 조각들이 가장 흔하고, 다음으로 유리조각, 금속조각의 순서로 발생한다. 특히 나무조각이나, 플라스틱 조각 등은 방사선투과성(radiolucency)을 가지고 있어 단순 방사선 사진으로 쉽게 발견하기 어려운 경우가 많아 외부 이물질을 찾는 것이 어려울 뿐만 아니라 일부 제거하더라도 이물질의 잔존 여부를 감별하기가 어렵다. 이에 저자들은 나무가시에 수상 당한 후 1차 의료기간에서 일부 나무가시를 제거 후 잔존 나무가시를 발견하지 못하고 수상 4주 이후 초음파을 이용하여 잔존 이물질을 진단하여 수술적으로 치료 후 동통의 감소를 보인 1례를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.

William Wordsworth's "The Thorn" revolves around the following questions: Who is Martha? Why does she go to the mountain top and repeat her doleful cry? To these questions, it gives us two different kinds of answers; one derives from the villagers, and the other from the narrator. This essay attempts to examine how the answers exemplify two different critical approaches to the problem of community, using Jacques Lacan's account of sexual difference in his seminar on Encore as a guiding thread of analysis. The important thing to retain here is that sexual difference in Lacan's seminar on Encore does not so much indicate biological determinations as two distinct forms of relating to the other which are intimately bound up with the question of how a community is constructed and maintained. The first form, called "masculine," suggests that it is a radical exception to a community that makes possible the community as a field of totality or sameness; the second form, called "feminine," shows that each of the subjects cannot be regarded as a member of a closed community which is guaranteed by the exceptionality, but as an exception that is radically singular. This in turn leads us to consider the possibility that the masculine form has to do with the villagers' effort to distinguish themselves from Martha and the feminine form with the way in which the narrator confronts and represents her. In the course of his formulation of sexuation graph, Lacan stresses that the masculine side must be supplemented by the feminine side, which allows us to elaborate on why, concerning Martha, the narrator does not just keep the completely different position from the villagers'. This is to say that the villagers' representation of Martha as an exception to the community should be supplemented by the narrator's attempt to tell Martha's story as the villagers do and at the same time to capture something of her enigmatic unrepresentability. Bearing in mind Charles Shepherdson's elaboration of traumatic memory, this essay also tries to clarify how the narrator preserves and even transmits something of Martha's truth that is embodied in her uncontrollable and unassimilable cry.

Two species of Phycitinae, Rabiria rufimaculella (Yamanaka, 1993) and Copamyntis martimella Kirpichnikova & Yamanaka, 2002, are reported for the first time from Korea. Rabiria rufimaculella can be recognized by having two reddish-yellow and short bands near the postmedial and antemedial line, and by the bifurcate gnathos and the cornutus which is formed by numerous thorn-shaped sclerites in male genitalia. Copamyntis martimella can be distinguished with the congeners by the uniformly distributed setae on the sacculus and the curved aedeagus in male genitalia and the peanut-shaped signum near the middle of the corpus bursae in female genitalia. The adults and genitalia of the species are redescribed and illustrated.

In the past, TR-cost was collected the combination of energy cost. When power market is restructured. TR-cost is collected the separated form of loss-cost, congestion-cost and maintenance-cost. One of thorn, loss-cost is computed by using TR loss-factor. We need correct and fair standards of loss factor to offer economical signal and to protect against confusions of investment and bidding. Therefore, we propose the method of minimizing system loss-cost that is based on fair and correct loss-factor.

The morphology and infraciliature of three newly recorded Aspidisca species in Korea, two collected from the eastern coast and one collected from Jeju Island, were investigated in vivo and after protargol impregnation. The three species are as follows: A. dentata Kahl, 1928, A. hexeris Quennerstedt, 1869, and A. polystyla Stein, 1859. The three species are characterized by having a "polystyla-arrangement" of frontoventral cirri: 1) A. dentata is characterized by having a broadly rotund body shape, a distinct peristomial spur, and a dorsal thorn; 2) A. hexeris is characterized by a broadly oval body shape, four projections along the left margin of body, and the single peristomial spur; and 3) A. polystyla has the broadly rotund body shape, transverse cirri each split into several parts (especially in vivo), and lacking of the peristomial spur. Among them, A. dentata and A. polystyla are poorly known and lack morphological description based on silver staining. In the present study, we provide a brief diagnosis, remarks, and photomicrographs.

The occurrence and time course of capacitation, acrosomal loss, and hyperactivated motility require quantitative definition in order to characterize fertile human sperm. Recently the method has been developed to estimate the quality of spermatozoa by using kinematic parameters such as curvilinear velocity(VCL), average path velocity(VAP), linearity(LIN), straightness(STR), amplitude of lateral head displacement(ALH), and beat cross frequence(BCF) from Computer Assisted Sperm Analysis (CASA). In this study, using the Hamilton Thorn motility analyzer HTM 2030(Hamilton Thorn Research, Beverly, MA), we attempted to identify the spermatozoa with hyperactivated motility (HA) objectively and to monitor hyperactivation of human spermatozoa during incubation in capacitating media and after treatment of calcium ionophore as compared with acrosome status. And we examined whether HA are related to the result of SPA. Semen samples obtained from 16 healthy men were prepared by swim up technique and preincubated in a capacitating media(modified BWW medium) for 5 hours and treated with calcium ionophore solution. The acrosome reaction was detected with PSA-FITC labelling of the acrosome and in vitro sperm ferilizing capacity was assessed by the zona free hamster ovum penetration assay (SPA). The incidence of hyperactivated sperm was 2.6% in fresh semen, 14.3% of the swim up population, 13.7% after 5h of incubation. Significant increase of percentage of hyperactivated sperm was observed after the incubation (p<0.05) but after treatment, no significant changes of percentage of hyperactivated sperm(l1.8%) in contrast to significant rise in the percentage of acrosome reacted cells. Correlation analysis failed to show any significant relationship between the percentage of sperm with HA and SPA score. In conclusion, although no direct correlations were found between the results of SPA and HA, hyperactivation of sperm is associated with capacitation and monitoring hyperactivated sperm will be expected as a method of evaluating the functional quality of sperm such as SPA.

본 연구에서는 보다 효율적인 동결 보존법을 수립하기 위하여 현재 사용되는 동결 보존액과 동결방법을 정자의 운동성 측면에서 비교해 보았다. 즉, 세 종류의 조성이 다른 동결보존액인 TYB, dithiothreitol을 첨가한 TYB+DTT, KS II 등이 동결보존 전후에 있어 운동성에 미치는 영향을 조사하였으며, 또한 vapor freezing 방법과 computerized freezer를 사용한 동결방법이 정자 운동성에 미치는 영향을 알아보았다. 정자의 분석은 현미경적 방법과 두 종류의 컴퓨터 정자 자동측정기인 SAIS와 Hamilton Thorn을 사용하여 동결 전 후의 정자 운동성과 VCL, VSL, VAP, ALH, LIN 등의 sub-motility 패턴을 측정하였다. 정액성상이 정상인 군에서 동결보존액을 비교한 실험결과는 TYB군과 TYB+DTT군, 그리고 KS II군의 융해 후 운동성이 각각 28.3%, 23.0%, 34.8%로 KS II군이 우수하였고, 동결방법을 비교한 실험에서는 vapor freezing 군과 computerized freezing 군의 융해 후 정자 운동성이 각각 27.8%, 33.2%로 유의차는 없었다. 또한 무력정자증을 보인 정액군에서는 TYB군과 TYB+DTT군, 그리고 KS II군에서 융해후 정자 운동성이 각각 13.6%, 10.0%, 18.5%로 여기 KS II군이 우수하였으며, vapor freezing군과 computerized freezing군의 융해 후 정자 운동성은 12.8%, 12.9%로 유의차가 없었다. 이상의 결과로 보아 운동성이 정상인 정액군과 무력정자증을 보이는 정액군에서 KS II를 사용해 동결하는 것이 TYB나 TYB+DTT를 사용하는 것보다 운동성 있는 정자를 회수하는데 더 효율적이며, 동결방법 측면에서는 vapor freezing 방법과 computerized freezing방법간에 큰 차이가 없음을 볼 수 있었다.
