Duplication of chromosome 7q has been reported as either partial or complete. Partial 7q duplication was first described by Carpentier in 1972. Pure partial duplication of the long arm of chromosome 7 is extremely rare and only 16 cases with a pure partial duplication of different 7q segment have been described in the literature. Pure partial duplication of the long arm of chromosome 7 is characterized by growth and developmental retardation, muscular hypotonia, distinct craniofacial dysmorphic features, a short neck and skeletal abnormalities. A 3 month-old male was referred to our department of Pediatrics because of dyspnea, hypotonia and delayed development. He shows growth and developmental delay, hypertelorism, a depressed nasal bridge, low set ears, a short neck and muscular hypotonia. Karyotype revealed 46, XY, dup(7)(q36q33) by GTC-banding. We report a case of a partial inverted duplication of chromosome 7q. 저자들은 호흡곤란, 근력저하, 발달지체로 병원에 온 3 개윌된 남아의 염색체 핵형분석에서 46, XY, dup(7)(q36q33)으로 진단된 1례를 경험하였기에 보고하는 바이다.

Background and Objectives : Vocal fold paresis is a clinical condition and considered as a continuum of neurologic dysfunction encompassing partial denervation and variable degrees and patterns of reinnervation. Its incidence, clinical presentation, significance are incompletely understood and still debated. This study describes the clinical, electromyographic findings in patients who presented with complaints of dysphonia and whose laryngoscopic finding revealed vocal fold paresis. Materials and Method : 47 patients (male : 25, female : 22) who referred to Ewha Womans University Medical Center Voice clinic for evaluation of vocal complaints were enrolled in this study. All patients had undergone a through history and physical examination including strobovideoscopic and laryngoscopic examination. Patients with in the history and/or laryngoscopic examination suggestive of vocal fold paresis were evaluated by laryngeal electromyography (LEMG). Results : Of these patients, 23 (48.9%) were found to have evidence of neuropathy on LEMG. There was no significant difference in voice symptoms and laryngoscopic findings between two groups of patients with evidence of neuropathy and who show normal findings on LEMG. Conclusion : LEMG can clinically help to guide the evaluation and management of vocal fold paresis. Due to some limitations of LEMG, laryngoscopic findings and clinical correlations should also be considered when diagnosing the vocal fold paresis.

Objectives Recently, vitamin D supplements to breast-fed infants are being encouraged in Korea, and other countries. However, the reliability and validity assessment of supplements is insufficient. Therefore, this study suggests new Korean guidelines for vitamin D supplements of breast-fed infant. Methods The roles of Vitamin D for bone metabolism in children and the correlation between breast milk and Vitamin D were examined throughout domestic and international literature review. In addition, the efficacy and safety of vitamin D supplements were reviewed. Results Preventive effects of rickets by vitamin D supplementation remain unclear. Furthermore, concerns about the safety of vitamin D supplements intake have been raised. Korean guideline suggests breast-fed infants can get vitamin D through the skin safely, but maternal intake of vitamins through sunbath and diet is more effective and safe. Conclusions Limiting sunlight excessively and applying foreign countries' medical guideline for vitamin D supplements are not valid to apply as a domestic guideline for Korean breast-fed infants without considering ethnic and cultural characteristics.

본 논문에서는 적록색각 이상자를 위한 색 변환 알고리즘을 제안한다. 적록색각 이상자는 원추세포의 이상으로 인해 색상과 명도를 일반인과 다르게 인지하기 때문에 적색과 녹색의 구분에 어려움을 겪는다. HSV 색공간은 이러한 특성을 파악할 수 있는 인간의 색지각과 유사한 색 공간으로, 제안하는 방법에서는 HSV 색 공간에서 색상과 명도를 보정하여 색을 변환 한다. 이때 색상과 명도 보정정도는 개개인의 색각이상 심각도에 따라 다르게 결정된다. 색각 이상자 개개인에 따라 다른 보정정도를 적용함으로서 기존 이미지의 자연스러움은 유지 하고 구분하기 힘들었던 색상들도 구분 가능하게 변환된다. 제안하는 방법을 색각 이상자에게 적용하여 시뮬레이션으로 확인한 결과, 색각 이상자가 구분하기 힘든 색상들이 색상의 자연스러움을 유지하면도 색차를 인지할 수 있는 색으로 변환되는 것을 확인할 수 있었다. This paper proposes a new re-coloring method for the people with the red-green color vision deficiency (CVD). These people have difficulty in discriminating the red and green colors since they abnormally perceive the hue and luminance value of the colors. We introduce a color transformation that adjusts the hue and luminance value in HSV color space. The color transformation is determined according to the severity of CVD. Our aim is to maintain the color differences in original image while maintaining the recolored image to be natural to the people with normal color vision. Experimental results show that the proposed method can yield more comprehensible images for the people with red-green CVD while maintaining the naturalness of the recolored images.

Objectives : The purpose of this study is to research the internet addiction and the Weak children. Methods : Total 400 of 5th and 6th grade JeonJu Elementary student children consisted with 203 men, 197 women were chosen for this study. They answered questionnaires of the internet addiction and the Weak children on June 12th, 2008. Results : 75% were general internet user, latent danger user group was 14.7%, high danger user group was 10.3%. The mean of the general weak children was the highest and then the group of children who had Heart, the Lung, the Liver, the Spleen, the Kidney problems were followed. These showed the relationships with living styles, especially eating patterns and parents' concerns about children's internet use. The more serious internet addiction was, the more the weaker children symptoms were answered significantly. The heart weak children symptoms were found in latent-high danger internet user group. Conclusions : In conclusion, the physical and psychological symptoms of the internet addiction children were resulted by the disturbance of Qi and the pathological change of internal organs.

The study aims to predict the behavior of tourists in Hadong County, which is registered as KIAHS. Based on the theory of planning behavior, we intend to verify the theory of planned behaviour, which adds descriptive parameters of the perceived value and prior knowledge of an agricultural heritage. In detail, first, the perceived value and prior knowledge of tourists about an agricultural heritage understand the influence of tourists' Attitude. Second, we could see the role of the behavioral factors in the causal relationship of the planned behavioral theory. We have identified the planned behavioral theory that attitudes, subjective norms, and perceptual behavior controls affect the intention of the revisit. Hadong should remember that by sending and providing various information about Hadong Green Tea and World Agricultural Heritage sites, it is possible to elicit changes in visitor attitudes and revisit visits.

본 연구에서는 단독주택 공부방을 대상으로 조명환경 실태조사를 실시하였다. 그 결과, 공부방은 주로 형광등을 사용하였으며 배광방식은 직접조명 방식을 사용하고 있었다. 또한 국부조명을 사용하는 비율은 48.2[%]로 시작업이 효과적이지 못하였다. 내부공간 조도는 평균 131.41[lx]이며, 책상면 조도는 322.57[lx]로 최저허용조도의 54[%]에 해당하는 열악한 실정이었다. 또한 사용자의 조명환경에 비해 만족도는 높아 조명에 대한 인식이 매우 부족한 것으로 사료된다. In this study, we investigated the actual conditions of illumination environment of study rooms in detached houses. From the results, fluorescent lamp as a lighting source and direct lighting method were mainly used. The additional use of local lighting was 48.2[%], and it was not efficient for detailed work. The average illuminance of general lighting and local lighting were 131.41[lx] and 322.57[lx], respectively, and these level were only 54[%] of the lowest illumination standard. This indicates that the lighting levels and the environment are so poor. The satisfaction level of users, however, was relatively high, suggesting insufficient recognition of importancy of lighting for efficient work.

The feeding habits of post-larval Yatabe blenny Parablennius yatabei (2.0-9.8 mm SL) were examined on the basis of 158 individuals collected from June to October in the coastal waters of eastern Jinhae Bay, South Korea. Based on the index of relative importance (IRI), post-larval P. yatabei fed 94.4% on copepods and 5.6% on tintinnids. The preference of post-larval P. yatabei for copepods to other prey items results from ontogenetic changes. The dietary percentage of copepods increased as fish size increased and tintinnids became less important. The feeding rate of post-larval P. yatabei was consistent at all times of day.
