Objectives : This is a clinical report about the Conversion Disorder, Wei symptom patient. Methods : The patient was treated by acupuncture, herb medication, moxibustion, physical therapy and bio feedback. The improvement of the patient was judged by lower limb elevation test and gait condition test. Results : During the 1st duration, lower limb elevation angle of the patient had improved. And the patient's gait condition had improved. But he received stress so that same symptom appeared again. Then, after the second treatment, He could walk alone again. Conclusions : Oriental medicine treatment including Acupuncture, Herb medication was very effctive to improve the Conversion disorder patient's symptoms. It is necessary to have more observation and many cases of patients with Conversion disorder.

Objectives : The purpose of this study was to evaluate the oriental conservative treatment for FBSS patient who were diagnosed as the Cauda equina syndrome. Methods : The patient were treated by the oriental medical conservative treatment including herbal medication, dry needle acupuncture, direct moxibustion and indirect moxibustion, cupping therapy and, physical therapy. We estimated by Visual Analog Scale and Oswestry disability index for evaluate the effect of Oriental conservative treatment. Results : After treatment, patient's visual analogue scale score and Oswestry disability index score were generally decreased. Conclusions : The oriental medical conservative treatment might be an effective method to treat the FBSS patient who were diagnosed as the Cauda equina syndrome.

Objectives : This study was to compare effects of scalp acupuncture with usual acupuncture on peripheral facial palsy in comparison with usual acupuncture only. Methods : We investigated 40 cases of patients with peripheral facial palsy, and devided patients into two groups: We treated one group by scalp acupuncture with usual acupuncture and did the other group by usual acupuncture only. To evaluate the effectiveness of treatment applied for two groups, we used Gross Grading System of House-Brackmann(H-B grade), Yanagihara's Unweighed Grading System(Y system). Results : 1. In H-B grade group B(common acupuncture therapy and scalp acupuncture)'s score was reduced than group A(common acupuncture therapy), but there was no statistical significance. 2. In Y-system group B was higher than group A, but there was no statistical significance. Conclusions : There was no stastical significance between two groups : treated by scalp acupuncture with usual acupuncture and usual acupuncture therapy only, on peripheral facial palsy.

Sin Dae-woo was a scholar representing the Ganghwa School in the late Joseon Dynasty. He was Jeong Je-du's grandson-in-law and also in charge of organizing Jeong Je-du's collection of writings. His three sons had a particularly close relationship with their father, so even when they published a collection of writings after his father's death, the names of the three were combined and marked as Jin-jak-shin. The records they left include Seokcheon Il-seung, who described the history of the family along with the collection of writings, Seongdo Il-rok, a diary of the time of Seongcheon Busa, and many letters exchanged over time. These records draw attention as they contain records of medical life, such as eye diseases that the family suffered, infectious diseases that caused many casualties, and Yakro (distilled herbal essence) that showed records of being used for treatment at the time. In this paper: 1) We examine the medicines, prescriptions, acupuncture, and medication used to treat eye diseases. 2) We carefully examine the epidemic, the responses of the parties to it, and the attitudes of those who stood at the boundary between death and life. 3) We look for clues to the use of Western-origin drugs called Yakro. Intellectuals of the time looked deeper into Lee Kyugyung's book and Seo Yu-gu's book on how they were reflected in Joseon's medical life. In conclusion, in the 18th and 9th centuries, we see that the influential families of the Ganghwa school freely brought in famous acupuncturists, used prescriptions that were included in medical books or not, and used Yakro from western origin that were not traditional methods of Joseon. Thus, we reveal that doctors of the Joseon had the capacity to pursue their medical life more actively and had open-minded exchanges than our existing perceptions.

본 논문에서는 근사 인코딩 기법을 이용한 H.264/AVC 비디오 코덱에서의 비트율 제어 알고리즘을 제안한다. H.264는 기존의 동영상 압축 표준보다 월등한 압축 성능을 나타내지만, 구조적 복잡성으로 인해 비트율 제어 측면에서는 과거에 제안된 H.264를 위한 비트율 제어 알고리즘들의 성능은 기대에 미치지 못하였다. 제안된 알고리즘은 근사 인코딩 기법을 사용하여 실제 H.264 인코딩이 이루어지기 이전에 향후 발생될 인코딩 비트를 미리 예측할 수 있고, 비트율 제어에서 매우 높은 중요성을 차지하는 프레임의 복잡도 예측에서 우수한 성능을 나타낸다. 알고리즘의 연산량 측면에서도 제안된 근사 인코딩 기법은 간단한 구조로 이루어져 있어 장점을 나타낸다. 본 논문에서는 DCT 영역에서의 각 프레임의 zero의 개수를 분석하여 얻어낸 영상의 특성을 비트율 제어에 활용한다. 실험결과는 제안된 알고리즘이 H.264 레퍼런스 소프트웨어의 가장 최신 버전인 JM12.2 환경에서 기존의 알고리즘에 비해 우수한 성능을 나타낸다는 것을 알 수 있다.

Today, meta-heuristic algorithms have been much attention by researcher because they have the power of solving combinational optimization problems efficiently. As the result, many variants of a meta-heuristic algorithm (e.g., simulated annealing) have been proposed for specific application domains. However, there are few efforts to classify them into a unified software framework, which is believed to provide the users with the reusability of the software, thereby significantly reducing the development time of algorithms. In this paper, we present an object-oriented framework to be used as a general tool for efficiently developing variants of simulated annealing algorithm. The interface classes in the framework achieve the modulization of the algorithm, and the users are allowed to specialize some of the classes appropriate for solving their problems. The core of the framework is Algorithm Configuration Pattern (ACP) which facilitates creating user-specific variants flexibly. Finally, we summarize our experiences and discuss future research topics.

The $CO_2$ emission can be decreased due to freedom of generator maintenance scheduling(GMS). This paper proposes assessment of $CO_2$ emission considering generator maintenance scheduling(GMS) and evaluates effect of the GMS on $CO_2$ emission. And also, this paper assesses the $CO_2$ emission and the probabilistic production cost simulation of nuclear and thermal power generators considering operation of hydro and pumped generator. The minimum reliability criterion level satisfied production cost minimization function model is used in this paper. The practicality and effectiveness of the proposed approach are demonstrated by simulation studies for a real size power system in Korea in 2010.

We here report a case of long-term fistula formation due to bullet retention for 30 years in the lumbar spine after a gunshot injury, and describe its treatment. A 62-year-old male visited our hospital due to pus-like discharge from his left flank. The discharge had been present for 30 years, since his recovery from an abdominal gunshot injury. A spine radiography showed radiopaque material in the body of the third lumbar vertebra. Foreign body was removed using an anterolateral retroperitoneal approach. The postoperative course was uneventful. The patient was discharged 7 days after the operation and was followed-up for 8 months, during which time, the fistula did not reoccur. A bullet retained long term in the vertebral body may cause obstinate osteomyelitis and fistula formation. A fistula caused by a foreign body in the spine can be effectively treated by surgical removal.

This study, soil sampling includes disturbed weathered granite soils from 8 different sites and disturbed weathered non-granite soils from 5 sample sites, put a purpose on finding for a utility possibility and practical use in this study. As a result of this study, internal friction angle & cohesion indicate which are from re-mold of samples by compaction seem to be able to use a compared to an field data. It is considered that strength parameter of disturbed weathered granite soil in the field is a useful reference.

The strength parameters of two different type of disturbed weathered soils were investigated by the triaxial tests in this study. Soil samples include granite soils from two different sites and non-granite soils from six sampling sites. The results of this study indicate that the triaxial tests could be employed for determining the strength parameters for disturbed soil samples. When additional parameters are obtained by further experiments, they could be utilized in various engineering design practices.
