Elderly women are reported to have greater risk of falls. The purpose of this paper was to investigate the possible gender differences in the reaction performance of ankle joint muscles, which have dominant role in the control of sagittal plane balance. Twenty-six elderly men and women with comparable mean age participated in this study. Reaction times to the audible beeps were measured in the tibialis anterior muscle and gastrocnemius muscle. Reaction time variables included premotor time, electromechanical delay and total reaction time. Gender difference in each reaction time was investigated by independent t-test. In both muscles, premotor time was longer in men but the electromechanical delay was longer in women (p < 0.05). Resulting total reaction time was longer in men in tibialis anterior muscle (p < 0.01) and it tended to be longer in men also in gastrocnemius muscle (p = 0.25). The results demonstrates that the overall reaction performances of elderly women is better than or comparable to those of elderly men in ankle joint muscles. This suggests that the reaction performance of ankle muscles is hardly the cause of the greater risk of falls in elderly women.

Objectives : The purpose of this study is to investigate recent clinical studies on the effect of acupuncture on hearing loss. Methods : Based on the PubMed search with the key search terms of 'hearing loss, acupuncture', dated from 2004 to 2017, 1 controlled trials, 3 case reports and 3 case series was found, and were analyzed for this study. Results : 1. The most commonly used acupoints were Shuaigu(GB8) and Fengchi(GB20). 2. The most commonly used meridians were the du channel, the gall bladder meridian of foot-shaoyang, and the triple bunner meridian of hand shaoyang. 3. Acupuncture treatment was effective for conductive and sensorineural hearing loss, especially sudden sensory neural hearing loss. 4. More clinical studies are needed to prove the effectiveness of the acupuncture on hearing loss. To be more objective on the study results, we can measure auditory brainstem response for hearing loss after acupuncture treatment.

Objectives Previous studies suggest that the cannabinoid receptor 1 (CNR1) gene could be an important candidate gene for schizophrenia. According to linkage studies, this gene is located on chromosome 6q14-q15, which is known to harbor the schizophrenia susceptibility locus (locus 5, SCZ5, OMIM 803175). The pharmacological agent delta-9-tetrahydrocannabinol (${\Delta}$-9-THC) seems to elicit the symptoms of schizophrenia. The association between CNR1 polymorphisms and schizophrenia is actively being investigated, and some studies have linked the AAT-trinucleotide repeats in CNR1 to the onset of schizophrenia. In this study, we have investigated the association between the AAT-trinucleotide repeats in CNR1 and schizophrenia by studying schizophrenia patients and healthy individuals from Korea. Methods DNA was extracted from the blood samples of 394 control subjects and 337 patients diagnosed with schizophrenia (as per the Diagnostic and Statistical Manual of Mental Disorders, fourth edition criteria). After polymerase chain reaction amplification, a logistic regression analysis, with age and gender as the covariates, was performed to study the variations in the AAT-repeat polymorphisms between the two groups. Results In total, 8 types of trinucleotide repeats were identified, each containing 7, 8, 10, 11, 12, 13, 14, and 15 repeats, respectively. $(AAT)_{13}$ allele was most frequently observed, with a frequency of 33.6% and 31.6% in the patient and control groups, respectively. The frequency of the other repeat alleles in the patient group (in the decreasing order) was as follows : $(AAT)_{13}$ 33.6%, $(AAT)_{14}$ 21.6%, $(AAT)_{12}$ 18.5%, and $(AAT)_{7}$ 11.1%. The frequency of the repeat alleles in the control group (in the decreasing order) was as follows : $(AAT)_{13}$ 31.6%, $(AAT)_{14}$ 24.5%, $(AAT)_{12}$ 17.2%, and $(AAT)_{7}$ 11.6%. However, there were no significant differences in the AAT-repeat polymorphisms of the CNR1 gene between the patient group and the control group. Conclusions Although our study revealed no significant association of the AAT-repeat polymorphism of the CNR1 gene with schizophrenia, it will serve as a good reference for future studies designed to examine the cannabinoid hypothesis of schizophrenia.

조각가의 꿈을 지녔던 소년 김원이 집안형편을 고려해 공과대학에서 건축을 공부한 것은 결과적으로 잘된 일이다. 대학 졸업 후 동기들은 미국 유학길에 올랐지만 그는 김수근 건축사무실에서 밤샘으로 현장을 지켰다. 스물아홉에 떠난 네덜란드 유학은 그 자체 문화적 충격이었고, 여행으로 건축문화예술의 실물을 접하는 기회였다. 돌아와 30여년간 명동 쌩뽈 수도원, 국립국악당, 광주 가톨릭대학교 등 2백여 건축물을 완성시킨 그의 일관된 건축관은 보편성이다. 우리나라의 그 상식적이지 않은 건축문화에 대해 숱한 분노의 발언을 쏟아낸 것도 그의 건축관을 실천하는 또다른 모습이다.

Lu<sub>3</sub>Al<sub>5-x</sub>Ga<sub>x</sub>O<sub>12</sub>:Ce<sup>3+</sup>,Cr<sup>3+</sup> powders are prepared using a solid-state reaction method. To determine the crystal structure, Rietveld refinement is performed. The results indicate that Ga<sup>3+</sup> ions preferentially occupied tetrahedral rather than octahedral sites. The lattice constant linearly increases, obeying Vegard's law, despite the strong preference of Ga<sup>3+</sup> for the tetrahedral sites. Increasing x led to a blue-shift of the Ce<sup>3+</sup> emission band in the green region and a change in the emission intensity. Persistent luminescence is observed from the powders prepared with x = 2-3, occurring through a trapping and detrapping process between Ce<sup>3+</sup> and Cr<sup>3+</sup> ions. The longest persistent luminescence is achieved for x = 2; its lifetime is at least 30 min. The findings are explained using crystal structure refinement, crystal field splitting, optical band gap, and electron trapping mechanism.

"근대적인 신문이 처음 발간되기 시작한 한말에서 일제시대까지 언론사는 현대사의 축도와 같은 양상을 띠었습니다. 암흑의 일제치하와 해방후 좌우익 대립, 이데올로기의 혼란 등 역사의 소용돌이 속에서 언론인은 지성인으로서 고난의 역사를 함께했고, 그렇기 때문에 언론인은 우리나라 역사의 주역으로 주목받아야 한다고 생각합니다."
