배구자는 1920~30년대 조선에서 큰 인기를 확보한 무용수이자 연극인이었다. 그녀는 배구자악극단을 창립하여 조선과 해외(일본)를 오가면서 공연을 펼쳤고, 대중들은 그녀의 작품을 보기 위해서 극장으로 몰려들었다. 그녀와 그녀의 극단이 인기를 확보하고 있을 무렵, 그러니까 1931년 배구자무용연구소는 '혁신 공연'을 선언하고 일련의 작품을 발표했다. 당시 공연 작품 중에는 가무극 <파계>가 포함되어 있었는데, 다행히 <파계>는 공연 대본으로 기록되어 현재까지 전해질 수 있었다. 남아 있는 가무극 <파계>를 통해, 배구자무용연구소(나아가서는 '배구자악극단')의 공연 전략과 레퍼토리의 실체를 파악할 수 있을 것으로 기대된다. 조선 근대연극(사)의 주요한 축을 담당한 배구자악극단에 대한 연구는, 일제강점기 조선의 대중극의 다양한 갈래와 그 특성에 대한 이해를 제고할 것으로 전망된다.

This paper investigates whether managerial ownership and foreign ownership have impacts on firm value, using a sample of logistics firms listed on the Korea Stock Exchange between 2008 and 2014. In the Korean economy, family-controlled business groups, known as chaebol, constitute a unique governance system. To acquire investments from controlling shareholders, a logistics firm is likely to be included in family-controlled business groups. Since reform of the governance structure of logistics firms in the South Korea enables shareholder value to be maximized, we analyzed ownership effects on firm value using pooled ordinary least squares. Empirical results showed that there was a significant positive relation between managerial ownership and firm value. This study also found that there was a significant positive relation between foreign ownership and firm value. We thus show that both managerial ownership and foreign ownership can protect shareholders by positively affecting firm values.

Some experiments were conducted to investigate the effects of the chemosterilant, hempa, on the biology of the rice weevil, Sitophilus oryzae L., and the transmission of the lethal factors in the progeny. One to three days old adult males were fed on the wheat grains treated with concentrations of 0.0625, 0.125, 0.25, and $0.5\%$ of hempa water solution. The effects of the treatment on the mortality, longevity, and the performance of oviposition were examined for the Pl generation, and the hatchability and mortality in the postembryonic development were also tested in the $F_1,\;F_2,\;BC_1,\;F_3,\;and\;BC_2$ generations to analyze the inheritance of the lethal factors. The results obtained were summarized as follows. (1) The average longevity of the treated males were ranged from 26.6 to 30.4 days, and indicated no statistical differences. (2) The mortality of the treated males were ranged between $3.3\%\;and\;13.3\%$ and showed no statistical significance. (3) The overall mean number of eggs laid by a female mated to a treated male with concentrations of 0.0625, 0.125, 0.26 and $0.5\%$ were 3.78, 4.05, 3.75 and 3.61 for the respective treatments, and they were not differ significantly from those of control which were 3.60 per female per 3 day period. The unmated female laid 1.91 in the same period, and significantly differ from those in other experimental groups. (4) The overall mean hatchability of the eggs laid by the females mated with males that had been treated with various concentrations of hempa were 86.82, 64.77, 53.47, 40.33 and $24.78\%$ for the respective concentrations of 0, 0.0625, 0.125, 0.25 and $0.5\%$. The hatchability decreased with the increasing concentrations. (5) The minimum hatchabilities were obtained from the eggs laid in the period of 10-12 days after treatment, then the hatchability increased showing some recovery. The recovery seemed to be very much delayed for the males which had been treated with the greater concentrations. Such a difference in hatchability might be related with the sensitivity of the developmental stages of the sperms, and broader spectrum in the stages and severer effects seemed to be associated with the increased concentrations. (6) The overall mean of larval mortality in the $F_l$ generation were 6.55, 17.89, 27.40, 35.42 and $52.17\%$ for the respective concentrations of 0,0.0625, 0.125,0.25 and $0.5\%$. And there was a tendency to increase in the mortality with the increase of concentrations. (7) The correlation coefficients between per cent sterile eggs and larval mortality for the experimental plots of 0.125, 0.25 and $0.5\%$ treatments showed r=+0.83 and +0.85, respectively, and it seemed to be close correlation between the lethal effects on the embryonic and post-embryonic developments. (8) Since the $SC_{50}$ of the sterile eggs was $0.133\%$ and $SC_{50}$ of the larval mortality was $0.565\%$, it was considered that tile lethal factors expressed more in the egg stages than the larval stages. (9) The ratio of female to male in the $F_l$ adults showed 100 : 125, 100 : 108 and 100 : 124 for the plots of 0.125, 0.25 and $0.5\%$ treatments, respectively. And it n·as considered that the sex ratio distortions might occur with the higher concentrations. (10) When the F, males originated 1.on the eggs had been laid by p, in the period of 16-18 days after treatment, were crossed to normal females $(BC_1)$ and made sib matings $(F_2)$, the per cent sterile eggs of the $BC_1$ generation were 13.88 and $33.04\%$ , and were 31.01 and $38.73\%$ for the $F_2$generation with the plots of 0.0625 and $0.125\%$ treatment, respectively. And these seemed to be a results of the $F_1$ individuals are carrying some chromosomal aberrations (11) The larval mortality was the highest in the $F_2$ plot and followed the female backcross plot, and the least in the male backcrosses. (12) The proportions of 1st and 2nd instar larvae among the larval development at tile 17th day after oviposition were 10.98, 27.26, 32.98 and $15.73\%$ in the normal female $\times$ normal male, $F_1$ female$\times$normal male, normal $female \;\times F_1$ male and $female \;\times F_1$ male plots, respectively. It was considered that the larval development might be delayed by the treatment in the 2nd generation. (13) Per cent larval mortality and sterile eggs were greater in the $F_2$ sib mating plots $(F_3)$ than both of $F_2$ backcrosses. Therefore, it seemed that some of the recessive lethal mutations might affect in the further generations. (14) The sterility, induced by the treatment of chemosterilant, hempa, was considered as the result of the dominant lethal mutations due to chromosomal aberrations such as translocation and/or deletion. The effects of these lethal factors seemed to be inherited tip to 3rd generation after treatment.

This case study identified the effects of joint mobilization on knee pain, isokinetic strength, muscle tone, and muscle stiffness in an elite volleyball player with a knee injury. The subject had experienced cartilage defects of the left knee joint and underwent surgery to correct the condition. The patient complained of continuous pain in the left knee joint in daily life in addition to pain during exercise. The study was conducted from August 5 to 12, 2015 and joint mobilization was applied to the left knee joint for 15 minutes once a day for 8 days. Knee pain was measured using a visual analogue scale, and the concentric peak torque of the quadriceps and hamstring muscles was measured using an isokinetic muscular strength measurement device. The muscle tone and stiffness of the rectus femoris muscle, vastus medialis, and vastus lateralis on the injured side were measured using a myotonometer. All the measurements were conducted before and after the intervention. Joint mobilization was effective in reducing knee pain on the injured side, increasing the concentric peak torque of the quadriceps and hamstring muscles on both sides, and increasing the muscle stiffness of the quadriceps muscle on the injured side. Concentric peak torque of the quadriceps muscle on the injured side increased a great deal as the number of joint mobilizations was increased, largely diminishing the difference in concentric peak torque between the normal side and injured side. On the other hand, joint mobilization was ineffective in improving the hamstring to quadriceps strength ratio on the injured side. While this study suggests that joint mobilization can be an effective intervention to improve the knee pain, isokinetic strength, and muscle stiffness of elite volleyball players, it should be performed alongside training for an appropriate strength ratio.

This study was conducted to evaluate the effect of the application of green manure in the form of either green barley and Chinese milkvetch in reducing the amounts of N fertilizers and conventional fertilizers needed for paddy rice. Prior to rice transplanting, the green barley and Chinese milkvetch as a green manure produced respectively $668kg\;10a^{-1}$ and 3,492kg\;$10a^{-1}$ in fresh shoot weight basis. Calculated nitrogen content from harvested green manures was 3.9 and $17.8kg\;10a^{-1}$, respectively. Plant height and tiller number of rice increased when two kinds of green manure incorporated into soil. Above mentioned parameters also increased with increasing amounts of N fertilizers at both ear formation and heading stage of rice. Rice grain number was not affected by green manures treatment but increased when N fertilizers were applied. Although rice panicle and grain number increased with green manure treatments and fertilizer applications, whereas the percentage of ripened grain decreased. Chinese milkvetch with additional N fertilizer applications increased brown rice yield from 1 to 5% compared to rice yields in plots where non-green manure with the conventional amount of fertilizer application was applied. Rice treated with Chinese milkvetch and 30% of the conventional N fertilizer rate yielded the same as rice fertilized conventionally. During the rice growing season, $NH_4-N$ content of paddy soil was higher in green manures treatment than non-green manure one. Average $NH_4-N$ content in paddy soil drastically decreased after heading stage below $5.7mg\;kg^{-1}$ in non-green manure treated plots. While on the other, $NH_4-N$ content in soil slowly decreased in plots those were treated with green manures at harvesting stage, average $NH_4-N$ content was still greater than $5.5mg\;kg^{-1}$. Nitrogen content of rice shoot and brown rice seed was higher in green manure treatment.

Mutual Savings Banks generally have weaker governance structure than other financial institutions, so the possibility of earnings management by owner-largest or managements of mutual savings banks is higher than other financial institutions. This study examines the relationship between corporate governance and quality of internal control of financial reporting. If the expropriation of minority shareholder hypothesis holds, we predict that the larger block shareholder in mutual savings banks, the weaker the internal control system by more likely the opportunistic earnings management by bank managers. On the other hand, under the convergence of interest hypothesis, we predict that the larger block shareholder in mutual savings banks, the stronger the internal control system by reduction in agency costs as owner-manager's holdings increases, and there a negative relationship is expected between internal control weakness and the holdings of the owner-largest shareholder. We find that mutual savings banks with higher owner-largest shareholder equity has significant positive relations with their internal control of financial reporting material weakness. This result suggests that the greater owner-largest shareholder equity, the more likely the opportunistic earnings management, so that decrease quality of internal control. This paper extends the literature on financial institutions corporate governance to verify whether governance system, especially, owner-largest and quality of internal control has significant positive relations.

Tetragomphius procyonis Baylis & Daubney, 1923 were obtained from the pancreatic duct of a naturally infected Eurasian badger, Meles meles, which was submitted to animal hospital for parasitic diagnosis from Gyeryongsan National Park in Korea. The hookworms were examined by light and scanning electron microscope. The length of body measured male 15.0-18.8 mm, female 21.5-25.5 mm, respectively. In both sex, the ventral cutting plates of oral margin are much reduced and elongated latero-dorsally, the dorsal cutting plate is located long follow doral margin of the oral opening. The buccal capsule is cup-shaped and thicken with four cusped tooth at its base. The copulatory bursa has elongated ventral lobes and their large rays are parallel, while the dorsal lobe with its supporting rays is slightly split in two. The slender spicules are filariform and very long (8.7-9.3 mm), and their tips are fused together. The hookworm has following characters: dorsal cone on the both sex, gubernaculum on the male and terminal spine on the female tail absent; vulva is opening in the juction of the fourths and fifths of the body; dorsal ray with two long stems. The eggs from the uterus are 16 cell stages and those from the rectal feces, 32 cell stages. The size of eggs is 77.48-83.45 ${\times}$ 50.75-63.38 ${\mu}m$.
