Tuberculous osteitis of the skull is an uncommon condition, first reported by Reid of Erlangen, who described two cases in 1842. By 1933. only 220 cases had been recorded in world literature (Strauss). It occurs in approximately 1%. of all patients with tuberculous osteitis and is diagnosed by clinical manifestation, skull roentgenogram, smear and culture of aspirated pus, and biopsy of granulation material. It responds readily to chemotherapy and the prognosis is favorable. To the best of our knowledge, the condition has not been previously reported in Korea. But recently we experienced a case of tuberculous osteitis of the skull in an 18-year-old male patient who complained of dyspnea, chest pain, multiple swelling of scalp and right eye proptosis. The patient was treated with antituberculous medication and discharged with his condition improved.

Accelerated lifetime test using a moment bar for a base frame of an aerial-work-platform vehicle
이기천,이영범,최병오,최종식,신영락,맹주원 대한기계학회 2017 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.31 No.8
The demand for high aerial work platforms has increased gradually. A safe and lightweight structure is necessary to cut short increasing costs of existing materials. To serve the purpose a base frame structure made of concrete and steel is developed for such a platform. However, it was difficult to replicate field conditions when testing the durability and safety of structure. In this study, the failure analysis of the base frame in the field operating condition for the reappearance and accelerated life test was performed. Also, the equations describing the characteristics of the aerial work platform for force and moment due to the weight and the wind at the top of the equipment were introduced and proved. Failure reappearance mechanism using the moment bar was applied for the force and moment simultaneously to the lower frame which reproduced the failure modes with the real size frame. Also, accelerated life test time was induced by using no failure life test time, the shape parameter, and acceleration factor which should be considered with the field operating conditions. The performance test was conducted after attaching the strain gauges at the weak points of the lower frame to prove the effectiveness of the moment bar. The strain values taken from the finite element analysis had the consistent results with the experimental data. It means that the moment bar can be applied to the other aerial work platforms.

이 연구의 목적은 KBL(Korean Basketball League)과 NBA(National Basketball Association)의 드래프트(Draft) 제도, 자유계약선수(Free Agency) 제도 그리고 샐러리캡(Salary Cap) 제도의 분석을 통해 두 리그의 전력균형 제도를 비교한 후 프로리그 경영자들에게 전력균형에 기여할 선수제도 관련 시사점을 제공하는데 목적이 있다. 두 리그의 전력균형 비교를 위해 KBL과 NBA의 드래프트 규정, 자유계약선수 규정, 그리고 샐러리캡 규정과 관련된 자료를 수집, 분석하였다. 자료는 KBL과 NBA가 제정, 공표한 공적 문서로서 자료 신뢰도는 매우 높다. 연구의 신뢰도 검증을 위해 자료 삼각검증법과 조사자 삼각검증법을 사용하였다. 타당도 검증을 위해 KBL과 NBA의 각 내부구성원을 통한 협의검증 방식을 채택했다. 자료의 처리는 전력균형 취지로 제정된 규정을 비교표를 통해 항목별 차이점과 유사점을 분석하였다. 연구결과 첫째, NBA는 드래프트 1~3순위 지명권을 플레이오프 탈락 팀에게만 일정 확률을 부여한 반면 KBL은 모든 팀에게 드래프트 1~4순위 지명권을 부여하고 있다. 또KBL은 외국인선수 드래프트 제도를 채택하고 있는데 지난 20년 간 5번이나 외국인선수 선발제도가 바뀌어 잦은 변화가 있었다. 특히 KBL은 외국인선수에 대한 신장 제한, 쿼터별, 라운드별 출전제한 규정이 있다. 둘째, KBL은 NBA에는 없는 자유계약선수 보상 규정 등을 별도로 두어 자유계약선수의 이적에 있어 구단이 동의하지 않으면 사실상 불가능하다는 것이다. 셋째, KBL과 NBA의 샐러리캡 제도의 차이로 KBL은 매우 경직된 하드캡으로 운용하는 반면 NBA는 각종 예외규정을 두고 있어 소프트캡으로 분류된다. KBL과 NBA의 샐러리캡 증가율에서 차이가 나는 이유로는 시장 규모의 차이 이외에 샐러리캡을 정하는 의사 결정구조의 차이에서도 영향을 받는 것으로 밝혀졌다. 이 연구의 시사점으로는 KBL은 드래프트 제도, 자유계약선수 제도, 외국인선수 출전제한 제도 등 비교적 강한 선수통제 방식을 고수하고 있다. 재정통제 방식인 샐러리캡 제도 역시 NBA에 비해 KBL은 선수와 리그가 동반성장을 하기 보다는 선수 연봉 인상 억제에 치중하는 것이 주된 목적이라는 점에서 제도를 적극적으로 재정비 할 필요가 있다고 본다. The purpose of this study is to provide professional league managers with implications after comparison of competitive balance systems between Korean Basketball League(KBL) and National Basketball Association(NBA) through the analysis of draft, free agency and salary caps regulation. Document and data was collected to analyze draft, free agency and salary cap systems of the both KBL and NBA. The reliability of the document is relatively high as the most of it is official documents published by KBL and NBA. Data triangulation and investigator triangulation were used to verify the reliability of this study. In order to verify the validity, researcher adopted a consultation and a review method, this has been done with both KBL and NBA staff. The data were processed by analyzing the differences and similarities after comparison of each table. The conclusions of this study are as follows: First, in KBL rookie draft system, every team is given the probability for the primary lottery pick order(1~4), however, in NBA, teams not proceeded to playoffs are only given the probability for the primary lottery pick order(1~3). KBL foreign player draft system has been changed 5 times since it's inauguration. In particular, KBL has restrictions on playing time of foreign players by each quarter and each round during the season. Second, with regard to free-agency system, KBL has a unique restriction and compensation rules which are not in the NBA, so it is virtually impossible for a free-agent player to transfer other team without the club's consent. Third, regarding salary cap system, KBL salary cap is classified as a hard cap, while NBA is classified as a soft cap because of various salary cap exceptions. The difference of increase rate in the salary cap between 2 league is due to different in salary cap decision making structure as well as the different market size. The implication of this study is that KBL maintains a relatively strong player control system. As a financial control system, also KBL salary cap rules are needed to revise because KBL salary cap has been implemented to restrain the players' salary increases rather than the growth of both the players and leagues itself through competitive balance.

An Ac-type Plasma Display Panel (PDP) operating with Ne-Ar(0.1%) Penning mixture gas is fabicated. The characterics of the panel with electrodes covered with thin and thick dielectric layers are studied. The brightness of the Neon-orange light emitted by the panel measured as function of applied voltage and frequency. As an application, a graphic display system equipped with PDP showing still and moving pictures is made.
