Purpose: The purpose of this study was to investigate the leg length Inequality, habitual posture, and pain in women's college students. Methods: The subjects were 281 students, in 8 women's college in Korea. The tapelines were used for measuring leg length Inequality and questionnaires were used for measuring habitual posture, and pain. The data were collected between August and October 2010 and analyzed using SPSSWIN 11.5. length Inequality(<1 cm). The subjects of 2.8% were the length differences of above 2cm. The worst habitual posture were leaning habits. Especially, the habits of crossing her legs were significantly different to leg length Inequality(F=3.342, $p$=.037). The subjects of 84% were felt a severe pain on the upper body such as waist, back, scapula, neck or shoulder. But there is no difference between pain and leg length Inequality. Habitual posture are related to pain(r=.212, $p$=.001). Conclusion: To protect the severe health problem of musculoskeletal system, this study results will be give aid to health education in women's college students.

This study was conducted to find the sexual size dimorphism(SSD) in morphometric characters of three species, Eremias argus, Takydromus amurensis and T. wolteri in lacertid lizard from Korea. Six external traits, snout-vent length, tail length, head length, head width, forelimb length and hind-limb length were focused to compare two sexes among the each three lizards. Student's t-test was used to compare the adult SVL between the sexes for each species. For the other parts of the body, a one-way analysis of covariance(ANCOVA) with SVL as the covariate was used. In all these species, males have longer tail and head than females like general lacertid lizard. In addition, male E. arugus have broader head and longer forelimbs and hind-limbs than conspecific females. Likewise, male T. wolteri have broader head than females. In the three lacertid lizards from Korea, snout-vent length did not significantly differ between the sexes. To understand the causes for SSD in SVL, ecological information, such as the presence/absence of male-male combat and the correlation between the SVL of female and litter size, is required. Therefore, further ecological study on the three species of lacertid lizard from Korea will make it possible to explain the reason SSD is not found in SVL.

The muscle activity and balance ability of the acute stroke patient has been checked by the functional electrical stimulation using biofeedback fusion postural control training in this study. Functional electrical stimulation using biofeedback fusion postural control training have been implemented on 15 trainees and general biofeedback fusion postural control training have been implemented on another 15 trainees for 30 minutes at 5 times per week during 8 weeks, and vastus lateralis, vastus medialis, rectus femoris and biceps femoris have been measured using the biceps femoris to evaluate the muscle activity of the lower extremity. The moving surface area, whole path length and limited of stability have been measured using biorecue to measure the balance ability. There was statistically meaningful difference on the vastus lateralis, vastus medialis, rectus femoris and biceps femoris in the muscle activity of the lower extremity and there was statistically meaningful difference on surface area, whole path length and limited of stability in the balancing ability. Based on above, it is realized that the functional electrical stimulation using biofeedback fusion postural control training is more effective than the general biofeedback fusion postural control training on the improvement of the muscle activity of the lower extremity and the balance ability.

Background: This study aims to examine correlations between quadriceps angle, lower extremity muscle strength and leg length discrepancy. Methods: This study selected 96 healthy women university students as the subjects of research. Quadriceps angle, lower extremity muscle strength and leg length discrepancy were measured. The statistical analysis of the data SPSS/window (version 12.0) were analyzed using the pearson correlation analysis. Results: There were negative correlations between the muscle strength of the right hamstring muscles and the right quadriceps angle in supine and standing positions. Functional leg length discrepancy of left and right quadriceps angle in supine and standing position showed positive correlations. Conclusions: The quadriceps angle affect the knee. An abnormal angle caused weakening of balance. Muscle strength, leg length discrepancy, and affected lower extremity alignment and knee function. These conclusions may prevent exercise limitation or disorders in the subjects and treating the patients with knee injury or patellofemoral pain syndrome with basic therapy intervention.

To most of the students studying fashion related major, the graduation fashion show is a big challenge. They have to put together all they learn and show what they can do to their future employers. They design, pattern work, and make up garments for the show all by themselves. Unfortunately. while they make up their garments, they usually don't Dow exactly body measurements of the models. So quite often they have to alter their art works up to the last minute of the fashion show opening. Sometimes such unadequate work process ruins their work. The purpose of this study is to suggest block patterns of Korean fashion models measurements for basic items, such as jacket and pants for male models and torso length block pattern, skirt and pants for female models. 20 male and 20 female professional models were measured. The block patterns were based on their measurements. After the first fitting test, patterns were corrected by their body characteristic. For both male and female models, it was found desirable to fix the shoulder width and make an adjustment to the patterns with a deviation of width and girth items. In case of the resultant patterns the satisfaction was made better. Model sizes proposed in this study are considered closer to the size of average models, since they were based on A-grade models who are currently working in Korea. The resultant patterns can be produced by simply making a slight adjustment to the width of the proposed pattern in this study.

This study was conducted to distinguish adult morphology of the giant water bug (Lethocerus deyrollei) between over-wintered (OLD) and new-born (NEW) populations using materials collected from Gyodong island in Gyeonggi-do, Korea, as well as individuals reared in the laboratory (LAB population) as a control. As a result, no fundamental differences were found in external body structure between OLD, NEW, and LAB populations. However, marginal area of basal procoxa in ventral prothorax and jointed part of forefemur and foretibia were greatly worn in the OLD population. Mid-claws were shorter than 0.5 times the length of the 2nd mid-tarsus; the membranous margin of hemelytra was greatly worn; and hairs of the 5th abdominal tergum were greatly reduced in the OLD population.

희귀식물(LC)인 낙지다리(Penthorum chinense Pursh.)는 '수택란', '차근채'로 불리며 약용으로 사용되어 왔으나, 최근 하천개수 및 습지매립 등으로 자생지가 파괴되어 개체수가 급감하고 있다. 따라서 본 연구는 낙지다리의 종 보존 및 활용을 위하여 종자의 최적발아조건을 확인하고자 수행하였다. 종자는 2017년 국립백두대간수목원에서 수집되어 연구에 사용되기 전까지 건조 상태(15℃, 15% RH)로 시드뱅크(-20℃, 40% RH)에 저장하고 있었다. 종자의 최적발아조건을 확인하기 위하여, 항온과 변온 66조건에서 발아율과 최종발아율의 50%가 발아하는데 소요되는 일 수(T₅₀)를 조사하였으며, 생리적 휴면 타파를 위해서 GA₃(20~1000 mg·L^-1) 처리 후 발아율과 T₅₀을 조사하였다. 그리고 GA₃ 처리에 따른 유묘 생장에 대한 GA₃의 영향을 확인하기 위하여 종자 치상 30일 후 유근·아 생장에 대한 영향을 조사하였다. 낙지다리 종자는 항온보다 변온에서 발아율 증가와 T₅₀ 감소를 보였다. 특히 낮/밤의 온도 차가 11~25℃일 때, 85%이상의 발아율을 보였고, 그 이상의 온도차이가 나면 발아율은 감소하는 경향을 보였다. T₅₀은 온도차가 증가할수록 감소하여, 발아가 균일하며 빨라지는 것을 확인 할 수 있었다. 또한 GA₃ 처리시 생리적 휴면 타파가 진행되어 발아율(79.8%~100%)과 발아속도가 증가(T₅₀ 감소)함을 확인하였으나, GA₃ 100mg·L^-1 이상의 농도에서는 무처리(21.2m)에 비하여 유근의 길이 생장을 0.11~6.88mm로 지연시켰다.

This study was conducted to investigate the individual size and age of Kaloula borealis, a pair in amplexus. In June 2013, the total 23 pairs of Kaloula borealis were captured in the wetland located in Seongsan-eup and Daejeong-eup, Jeju Island. Size and age of each individual have been examined and as a result of analyzing SVL (snout-vent length), weight, length of forelimb and hindlimb of the collected 23 pairs, the females were shown to have the heavier weight and the longer SVL and hindlimb compared to males. No significant difference in the length of forelimb has been found between the female and the male. The average age of the male of the pair in amplexus was shown to be $5.17{\pm}0.26$, whereas the female was shown to be $6.22{\pm}0.28$, which indicates the higher average age in female compared to the male. The age range of Kaloula borealis was distributed from at least 3 years to 10 years at the maximum. A positive correlation was shown between age of the male and SVL; however, no significant difference was found in female. This study result expected to be utilized as an important base data in establishing the preservation and restoration strategy of endangered species, Kaloula borealis.

The purpose of this study was to investigate the influence of gender and load carriage difference on the lower extremity kinetics during stair descent. Ten healthy males and 10 healthy females were recruited (n=20). In the Maximum resultant velocity, it showed more velocity was decreased with difference by the change of gender (males>females) and load carriage (30%, 20%, 10%> 10%). And, resultant velocity showed interaction between gender and a load (load>gender). Main effect by gender during stair descent showed leg length was decreased in females than that of males at initial contact phase. Also, main effect by gender during stair descent showed more hip, knee flexed and plantar flexion of ankle joint in females than that of males. In the kinetics variables, main effect by gender during stair descent showed more higher reaction force of medial-lateral direction, and leg stiffness in males than that of females. We found that females successfully accommodated a load during stair descent by decreasing the range of motion of the hip joint angle and resultant velocity of movement. Males, on the other hand, require greater medial-lateral, vertical reaction force, and leg stiffness to accommodate a load, and control of momentum.
