한국산 부전나비과 40종 2,850여 개체를 재료로 광학현미경으로 발향린의 유무 및 분포를 확인하였다. 이중 발향린이 확인, 관찰된 8종을 대상으로 주사전자현미경을 이용하여 미세구조를 비교하였다. 발향린이 관찰된 종은 Pseudozizera maha(K.), Celasrtina argiolus(L.), Everes argiades (P.), Lycaeides argyronmon(B.), Zizina otis(F.), Maculinea arionides(S.), M. teleius(B.), Niphanda fusca(B. et G.)등 8종이었다. 암컷에서는 발향린이 관찰되지 않았고 수컷에서만 확인되었으며, 앞날개의 표면과 이면, 그리고 뒷날개의 표면에서 관찰되었다. 발향린은 주로 중맥, 주맥, 둔맥에 분포하였으며 종별로 형태적 차이를 보였다. 확인, 관찰된 8종의 발향린은 잎새, 자루병반만을 가지는 단순한 모양을 나타내었다. Niphanda fusca는 잎새모양과 자루병반의 위치 등 많은 차이점이 확인되었으며, Pseudozizeera maha, Everes argiades등 2종에서는 두가지 형태의 발향린이 관찰되었다. 본 연구에서는 관찰된 8종은 모두 Polymmatina아과에 속하였다. 이중 Niphanda fusca는 Niphandini족에 속하며 나머지는 Polymmatini족에 속하였다.

Lead-acid battery is being most widely used with secondary battery because of its low price, and long life cycles. But According to using for a long time, its voltage, capacity, and recovery ability is decreased gradually. Therefore there are many papers about improving the property of a lead-acid battery. One of them is to slow down sulfation due to formation of inner PbSO sub(4) by adding inhibitor to electrolyte, however it was not well known what is inhibitor's composition and its role acting on both cathodic and anodic electrode because of its know-how of every country and companies. The purpose of this paper is to study about improvement of property of lead-acid battery by adding one of the inhibitor to H sub(2) SO sub(4) electrolyte.

본 연구는 한국제조업의 해외투자가 집중되어 있는 중국과 인도네시아에 진출한 한국자회사와 한국본사 생산직 종업원간의 조직몰입도(Organizational Commitment)를 비교 분석하었다. 조직몰입도는 크게 감정적 몰입(Affective Commitment)과 계산적 몰입(Continuance Commitment) 두차원으로 나눠 비교 분석하였다. 806명의 생산직 근로자들의 조직몰입도는 세 국가별로 크게 차이가 나는 것으로 나타났다. 일반적으로 기존연구에서는 본사근로자들의 조직몰입도가 해외자회사의 몰입도보다 높을 것으로 인식하고 있다. 그러나 본 연구 결과에 의하면 감정적 몰입 차원에서는 중국 근로자와 인도네시아 근로자들이 한국 본사근로자에 비해 매우 높게 나타났다. 그러나 계산적 몰입차원에시는 인도네시아 및 한국근로자들에 비해 중국 근로자들이 현저하게 낮은 것으로 분석되었다. 아울러 본 연구에서는 조직몰입도에 영향을 끼치는 선행변수와의 관계를 살펴보았다. 선행변수로는 나이, 근무년수 등의 개인적 변수, 직무특성변수, 공식화 및 집중화 등의 조직특성변수, 그리고 국가변수들이 사용되었다. 분석결과 감정적 몰입도에 영향을 끼치는 변수로 국가변수, 공식화, 기술다양성 등이 유의하게 나타났고, 계산적 몰입도는 국가변수, 공식화, 집중화 및 직무자율성 등이 유의한 상관관계를 보였다.

The powder forging process is an attractive manufacturing route for bevel gears. It offers beneficial material utilization and the minimization of finishing operations over that of conventional hot forging. The paper describes the process conditions for the powder forging of bevel gear, for example, powder alloy design, preform design, deformation of sintered preform, forging processes. The characteristics of prototype gear are investigated with microstructure, the density distribution, surface roughness of tooth, bending strength test of tooth, etc. The results of the bending strength test may prove the mechanical properties of powder forged gear.

It is well known that the metallo-phthalocyanine(MPcs) are sensitive to toxic gaseous molecules such as NO2 and also chemically and thermally stable. Therefore, lots of MPcs have been studied for the potential chemical sensor for NO2 gas using quartz crystal microbalance or electrical conductivity. In this study, 2,3,9,10,16,17,23,24-[octa-(dodecyloxy)] copper phthalocyanine and 2,3,9,10,16,17,23,24-[octa-(octyloxy)] copper phthalocyanine were synthesized and their possibility of LB film preparation were tested. It was confirmed by using FT-IR, DSC, NMR, UV-Vis absorption spectroscopy and Elemental Analysis that CuPc derivatives were successfully synthesized. From the π-A characteristics and limiting areas of two CuPc derivatives it was found that the preparation of LB films with these CuPc derivatives is possible.

The purpose of this study was to determine the effects of transcutaneous electrical nerve stimulation(TENS) on delayed onset muscle soreness(DOMS). Twenty males performed eccentric exercise of the elbow flexor. Subjects were randomly assigned to one of three groups: 1) a group (=7) that received low frequency TENS (7 Hz), 2) a group (=7) that received high frequency TENS (500 Hz), 3) a control group (=6) that received no treatment. DOMS was induced in a standardised fashion in the non-dominant elbow flexor of all subjects by repeated eccentric exercise. Treatments were applied immediately following exercise and again at 24 hours and at 48 hours after. Subjects attended on three consecutive days for treatment and measurement of elbow flexion, extension and resting angle(universal goniometer), and pain(Visual Analogue Scale; VAS) on a daily basis. Measurements were taken after treatment. Analysis of results using repeated measures analysis of variance(ANOVA) and post hoc tests were as follows: 1) there were between groups differences in pain value at 48 hours after (p<0.05), 2) one-way ANOVA with repeated measurement for pain, resting angle, flexion angle and extension angle revealed significant differences within low frequency TENS group, 3) one-way ANOVA with repeated measurement for flexion angle revealed significant difference within high frequency TENS group.

The ability to maintain an upright position during quiet standing is a useful motor skill. The Sensory Organization Test (SOT) is a timed balance test that evaluates somatosensory, visual, and vestibular function for maintenance of upright posture. The Fugl-Meyer Sensorimotor Assessment (FMSA) balance subscale is the functional status assessment that indicates amount of assistance needed during various balance tasks. Functional Independence Measure (FIM) is the functional status assessment tool and FIM can be used clinically as an outcome measure. The purpose of this study was to see if the SOT can be used as a evaluation tool to measure hemiplegic patients' balance ability. Thirty-six patients with hemiplegia participated in this study. SOT scores were significantly correlated with FMSA balance scores and FIM scores(p<0.05). However correlation coefficients were not so high (r=0.60, and r=0.51, respectively). Therefore, further study is needed to verify the SOT's usefulness when physical therapists are evaluating for hemiplegic patients' balance ability.
