Purpose: To determine changes in the degree of pseudomyopia and convergence in patients with spasm of the near reflex. Methods: In 5 patients with spasm of the near reflex, we checked following: UCVA/BCVA, the degree of pseudomyopia revealed through manifest and cycloplegic refraction tests, pupil size, limitation of EOM, the amount of convergence defined by the alternate prism cover test, and slit lamp and funduscopic exams. Results: Of the 5 patients with spasm of near reflex, 3 had accommodative spasm alone and 2 had accommodative spasm, convergence spasm and miosis. The patients` degrees of pseudomyopia and convergence were -8.0D and 14PD on the average. which disappeared after an average of 10.8 months but recurred in 1 of the 3 patients with accommodative spasm. As for spasm of the near reflex, 1 patient showed improvement in convergence but worsening pseudomyopia during the follow-up period, and another patient showed recurrence. Conclusions: The most common clinical feature of spasm of the near reflex is accommodative spasm. Patients with accommodative spasm alone showed better prognosis among all patients with spasm of the near reflex in terms of recurrence and the disease course.

박수양,손상희,정원섭,Park, Soo-Yang,Son, Sang-Hee,Chung, Won-Sup Institute of Korean Electrical and Electronics Eng 2007 전기전자학회논문지 Vol.11 No.1

A new 8-bit single-slope ADC using analog RAMP generator with digitally controllable dynamic range has been proposed and simulated for column level or per-pixel CMOS image sensor application. The conversion gain of ADC can he controlled easily by using frequency divider with digitally controllable diviber ratio, coarse/fine RAMP with class-AB op-amp, resistor strings, decoder, comparator, and etc. The chip area and power consumption can be decreased by simplified analog circuits and passive components. Proposed frequency divider has been implemented and verified with 0.65um, 2-poly, 2-metal standard CMOS process. And the functional verification has been simulated and accomplished in a 0.35$\mu$m standard CMOS process.

본 논문에서는 상위 수준 합성에서 연산자들의 스위칭 최소화를 통한 저 전력 자원 할당 알고리즘을 제안했다. 본 논문에서는 이미 스케줄링 된 CDFG를 대상으로 전력 소모의 원인이 되는 스위칭 동작을 최소화하는 자원할당 알고리즘을 제안한다. 제안된 알고리즘은 DSP 분야의 회로나 필터를 대상으로 연산자가 소모하는 전력을 최소화 하고자 한다. 스케줄링 된 CDFG상에 있는 여러 개의 연산은 자원공유를 통하여 같은 기능 장치에 구현될 수 있다. 이런 경우 두 개의 연속적인 연산의 실행사이에 각 연산의 입력 변수들이 연속적으로 변화하기 때문에 기능장치의 스위칭동작이 변하게 된다 이때 자원할당 과정에서 기능장치의 입력 신호들 사이의 스위칭동작과 상관관계를 고려하여 소비전력을 감소시킨다. 본 논문에서 제안하는 방법을 이용하여 자원할당을 할 경우 기존 방법과 비교했을 때 그 수행속도는 사용하는 연산자의 수와 최다 제어 단계에 따라서 빨라 질 수 있다. 그리고 소모하는 전력의 경우, 작게는 8.5%에서 9.3%까지 감소효과가 있다. This paper proposed a low power resource allocation algorithm for the minimum switching activity of operators in high level synthesis. In this paper, the proposed method finds switching activity in circuit each functional unit exchange for binary sequence length and value bit are logic one value. To use the switching activity was found the allocation with minimal power consumption, the proposed method visits all control steps one by one and determines the allocation with minimal power consumption at each control step. As the existing method, the execution time can be fast according to use the number of operator and maximal control step. And it is the reduction effect from 8.5% to 9.3%.

김정은 시대 범죄 유형 및 대책에 관한 연구 : 사례 분석을 중심으로

김윤영(Kim, Yun-Young),박수양(Park, Soo-Yang) 북한학회 2021 북한학보 Vol.46 No.1

북한은 국제사회의 제재로 식량난과 경제난이 악화하면서 주민들은 생활고에 시달리고 있다. 주민들은 먹고살기 위해서 밀무역, 장사, 불법 월경 등을 하는 과정에서, 자본주의 문화 콘텐츠를 유입해 도벌이 수단으로 이용하고 있다. 이러한 비사회주의 문화 문화유입과 함께 절도범죄, 청소년 범죄, 성범죄, 폭력 범죄, 살인 범죄, 마약범죄 등이 발생하고 있다. 북한당국은 범죄를 예방을 위해서 각종 법령의 제정과 개정, 범죄사례와 처벌 방법 등의 각종 대책을 내놓고 있다. 최근 김정은은 각종 중앙 회의를 통해 자본주의 문화 차단을 위한 지시를 하고 있다. 이러한 대책과 지시에도 불구하고 다양한 범죄가 계속 발생하고 있다. 이 글은 북한의 범죄유형과 대책에 대해 살펴보았다. 이러한 연구목적을 달성하기 위해서, 필자가 최근 입수한 북한 자료와 탈북민의 수기나 면접자료, 국내 및 해외 언론 기사, 선행연구 자료 등을 활용하였다. 이러한 연구는 향후 남북통합 과정에서 북한의 범죄실태에 대한 대응책을 제시할 수 있는 기초자료로 활용될 수 있을 것이다. In North Korea, food and economic difficulties are worsening due to international sanctions. North Koreans are suffering from hardships. Residents engage in smuggling, trade, and illegal border crossings to make a living. In this process, capitalist culture is introduced and disseminated, and crimes such as thetf, juvenile crimes, sex crimes, violent crimes, murder crimes, and drug crimes are occurring. The North Korean authorities are proposing various measures to prevent crime, such as enactment and revision of laws and regulations, and cases and methods of punishment for crimes. Recently, Kim Jong-un held various meetings and gave instructions for cracking down on capitalist culture. Despite these measures and instructions, various crimes are occurring. Therefore, this article examines the crime situation and countermeasures in North Korea. In order to achieve this research purpose, the North Korean data obtained by the author, handwriting and interview data of North Korean defectors, domestic and foreign media articles, and previous research data were used. This study can be used as basic data to suggest countermeasures to North Korea s crimes in the future inter-Korean integration process.

N/A Determination of sediment type is generally based on ground truthing. This method, however, provides information only for the limited sites. Recent developments of remote classification of seafloor sediments made it possible to obtain continuous profiles of sediment types. QTC View system, which is an acoustic instrument providing digital real-time seabed classification, was used to classify seafloor sediment types in the Suyoung Bay, Pusan. QTC View was connected to 50 kHz echo sounder. All parameters of QTC View and echo sounder are uniformly kept during survey. By ground truthing, the sediments are classified into seven types, such as slightly gravelly sand, slightly gravelly sandy mud, gravelly muddy sand, clayey sand, sandy mud, slightly gravelly muddy sand, and rocky bottom. By the first remote classification using QTC View, four sediment types are clearly identified, such as slightly gravelly sand, gravelly mud, slightly gravelly muddy sand, and rocky bottom. These are similar to the result of the second survey. Also the result of remote classification matches well with that of ground truthing, but for sediment type determined by minor component. Therefore, QTC View can effectively be used for remote classification of seafloor sediments.

양유미,김성식,전은숙,박수병 대한치과교정학회 2006 대한치과교정학회지 Vol.36 No.4

본 연구는 밴드 제거 직후 및 4주 경과 후 치주조직의 임상적인 환경변화와 미생물 분포 변화를 알기 위해 시행하였다. 최후방 구치에 밴드를 포함하는 고정식 교정 장치를 장착하고 교정 치료를 1년 이상 시행한 17명의 환자를 대상으로 하였다 (평균 나이 22세, 남자 6명, 여자 11명). 최후방 구치의 밴드를 제거한 직후와 제거 후 4주가 경과한 다음에 치주조직의 탐침 깊이와 출혈 빈도를 측정하였으며, 치은 연하의 치태를 채취하여 미생물의 분포를 조사하였다. 치주질환에 관련성이 깊은 미생물 중 Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola를 직접 Polymerase Chain Reaction 방법으로 존재 여부를 확인하였다. 밴드 제거 직후와 제거 후 4주가 경과한 시점의 치주조직의 탐침 깊이와 출혈 빈도, 병원성 미생물의 존재 여부를 통계적으로 비교하였다. 탐침 깊이와 출혈 빈도는 모두 하악 좌측 구치 협면에서 감소율이 가장 크게 나타났고, 상악 우측 구치 설면에서 감소율이 가장 작게 나타났다. 병원성 미생물 중 T. denticola가 밴드 제거 4주 후에 가장 높은 감소율을 보였으며, 하악보다 상악에서 감소율이 더 크게 나타났다. 이는 비록 밴드를 장착하여 치주 환경이 불량해졌다 하더라도 올바른 구강 위생 관리가 시행된다면 밴드를 제거한 후 정상적인 치주 상태로 회복될 수 있음을 예시한 것으로 생각되었다. Objective: The purpose of this study was to evaluate clinical and microbiological changes in periodontal tissue around the banded molars after debanding. Methods: This study included 17 young adult patients treated with fixed orthodontic appliances including bands on the last molars more than 1 years. Probing depth and bleeding frequency were measured and plaque samples were collected from the last banded molars in all quadrants of each patient. All the data were collected immediately after debanding and 4 weeks after debanding. Results: Using polymerase chain reaction based on 16S rDNA, the presence of Porphyromonas gingivalis, Tannerella forsythia and Treponema denticola was detected. After debanding, probing depth, bleeding frequency, and prevalance of periodontopathogens were reduced. Probing depth and bleeding frequency were most decreased in the buccal site of the mandibular left molar and were least decreased in the lingual site of the maxillary right molar. Conclusion: The results of this study indicated that proper management of oral hygiene after debanding can recuperate unfavorable periodontal condition caused by orthodontic treatment.

In this paper, the op-amp with new structure is proposed and designed to drive large capacitive loads of TFT LCD panel. The proposed op-amp is composed of rail-to-rail structure for full swing from VDD to GND. To reduce static current of op-amp, gate voltage difference of _(p)MOs and _(n)MOs in output buffer is more enlarged using self-biasing circuit. The proposed op-amp can be used as a buffer of TFT LCD Source driver to drive large TFT LCD panels. It is simulated bar HSPICE with 0.35 ㎛ CMOS standard process.
