In order to effectively control waves in a coastal zone, Multi-Cylinder Piles have been suggested as economic structures. A numerical analysis was conducted using the Delft-3D: WAVE module based on SWAN, which considered wave shoaling and refraction. Moreover, irregular waves were used to investigate the hydrodynamic characteristics of the wave interaction with the structure. In this paper, a numerical analysis was carried out to research the effect of wave control through a wave height analysis concerning an existing, concrete wave breaker and multi-cylinder piles placed at the same location. As a result, the effect of the wave control is shown using the wave breaker, multi-cylinder piles, and existing data.

이메일 사용이 보편화됨에 따라 점차 수신되는 메일의 량이 증가하고 있다. 이러한 메일 량의 증가는 사용자로 하여금 이메일을 좀더 효율적으로 분류할 수 있는 방법을 필요하게 한다. 그러나 현재의 이메일 분류는 규칙기반, 베이시안, SVM 등을 이용하여 스팸메일을 필터링 하는 이원분류가 주로 연구되고 있다. 이외에도 다원분류에 대한 연구로는 클러스터링을 이용한 방법이 있으나, 이는 단순히 유사도에 의해 메일을 묶는 수준에 그치고 있다. 본 논문에서는 벡터모델의 유사도를 기반으로 한 분류 주제 자동 생성 알고리즘과 동적분류체계 방법을 결합하여 새로운 이메일 자동 다원분류 방법을 제안했다. 본 논문에서 제안한 방법은 이메일을 자동으로 분류하여, 분류된 결과를 색인검색과 디렉토리 검색 방법을 지원하며 대량의 메일도 효율적으로 관리할 수 있다. 또한 메시지를 동적으로 재분류 할 수 있게 함으로써 디렉토리 검색시 재현율을 높였다.

Narcolepsy's age at onset is reported to be relatively homogeneous, occuring usually after the onset of puberty, although most cases are diagnosed when the patients are in their late teens to late 20s. It is very unusual for a patient to develop narcolepsy before 15 years of age or after 30 years of age. A 11-year old boy who has developed excessive daytime sleepiness since age of 7 and has all the four major features of narcolepsy by the time of evaluation is presented. On polysomnographic examination, the patient showed two sleep onset REM periods in the three latency test of the multiple sleep latency test and the nocturnal polysomnogram. In addition, the findings of typing HLA class I and II of the patient's family are presented. Reports of pediatric narcolepsy previously reported are reviewed.

The authors report a case of REM sleep behavior disorder which occurred in a 69-year-old business man. He began experiencing episodic "acting out" behavior of his dream at the age of 66. The episodes tended to be associated with dream contents, mainly being chased or threatened. Before that, his sleep was relatively quiet despite occasional nightmares, midsleep arousal, and shallowness. Injuries resulted from leaping out of bed, jumping onto furnitures, and grabbing and biting the spouse's arm. Most recent dream-incurred laceration of chin required 5 sutures. Medical and psychiatric history revealed no significant findings except that he had been overanxious all his life within himself with others' reputation of himself as pleasant and easy-going. A nocturnal polysomnogram showed repeatedly intermittent increase of chin and/or leg muscle tones during otherwise characteristic REM sleep period. The overnight video recording revealed head lifting and limb movements during REM sleep periods. Brain MRI and EEG were normal. Job-related stress was presumed to be an etiological possibility. Clonazepam 0.25-0.5mg nightly almost completely relieved the symptoms.

This paper deals with a generalized similarity solution for the one-dimensional solidification of ternary or higher-order multicomponent alloys. The present approach not only retains the existing features of binary systems such as temperature- solute coupling, shrinkage-induced flow, solid-liquid property differences, and finite back diffusion, but also is capable of handling a multicomponent alloy without restrictions on the partition coefficient and microsegregation parameter. For an alloy of N-solute species, governing equations in the mushy region reduce to (N+2) nonlinear ordinary differential equations via similarity transformation, which are to be solved along with the closed-form solutions for the solid and liquid regions. A linearized correction scheme adopted in the solution procedure facilitates to determine the solidus and liquidus positions stably. The result for a sample ternary alloy agrees excellently with the numerical prediction as well as the reported similarity solution. Additional calculations are also presented to show the utility of this study. Finally, it is concluded that the present analysis includes the previous analytical approaches as subsets.

Purpose: The purpose of this study was to identify the effects of hand acupuncture therapy on sleep quality by means of a sleep questionnaire, polysomnography and a cerebral blood flow test in $30{\sim}59$ year old adults. Methods: The study was a sham controlled design. Twenty-two adults were assigned to the pellet stimulating group (11) or sham group (11). The pellet stimulating group received hand acupuncture therapy using New Seoam Press Pellets number 1 for 4 weeks. On the other hand, the sham group used the same Adhesive tape in terms of shape, size and quality as New Seoam Press Pellets number 1 for 4 weeks. A Transcranial Doppler Ultrasonography and Carotid Duplex Ultrasonography examination were used for evaluating cerebral blood flow. Data was analyzed using the SPSS 12.0 version program with $X^2-test$, Fisher's exact test and Mann Whitney U-test. Results: In the pellet stimulating group, subjective sleep quality significantly improved more than that of the sham group. Among the sleep indices of the polysomnography, total sleep time and sleep latency of the sham group significantly improved. The cerebral blood flow test didn't show any differences. Conclusion: These results suggest that hand acupuncture therapy is effective for subjective sleep improvement only, not polysomnographical sleep indices and cerebral blood flow.
