Position decision system embody to interpret for observation target position. Observation target is observed at observation post of 3 places. CCD cameras of observation post is achieved turning control by stepping motor. Controller interpret observation target's position to use direction and angle information of observation post. Controller and observation post used PIC16F877. PIC16F877 achieves rotation control of stepping motor and distance arithmetic of observation target. Result that measure this system 50 times was achieved correct position interpretation of 47 times. Position interpretation failure of 3 times was construed for cause in used controller special quality.

This research will attempt to reveal that private developers in the Malaysian construction industry have been practicing strategic partnering in their organizations. While the investigation was conducted using quantitative and qualitative approaches, this paper will only reveal results obtained from the questionnaire survey. Results from the questionnaire survey indicate that private developers in the Malaysian construction industry had implemented strategic partnering in their organizations. The elements of the partnering process, which are partnering formation, partnering application and partnering completion or reactivation were tested. The results show that all the elements of the partnering process have been exercised in their projects. Thus it can be surmised that strategic partnering has been practiced by private developers in the Malaysian construction industry.

The purpose of this study is to develop and apply a teaching-learning plan of apartment house class to improve middle school students' empathy for home economics education and to verify its effect. The study was conducted in five stages: analysis, design, development, implementation, and evaluation using the ADDIE model. In the analysis phase, the study set learning objectives after analyzing how community housing is dealt with in the 2015 revised home economics curriculum and 12 current technology and home economics textbooks. In the design and development stage, in order to evaluate the validity of the experts and to improve the empathy ability, the study goal design, the composition of the learning elements, the development of the learning materials, and the pre and post-questionnaire for the students were developed. In the implementation stage, the empathic ability evaluation was carried out before and after the beginning of the first class by applying the teaching-learning process plan of the 8th class. In the evaluation stage, we examined whether the teaching-learning process developed in this study has a significant effect on empathy ability by evaluating the pre-post difference of empathy ability. As a result of examining the results of the pre - and post - evaluation of empathy ability for the results of this study, both cognitive and communicative factors were improved, and the apartment house class had a significant effect on the improvement of empathy ability.

Korean fortis consonant is not included in the consonantal inventory, but a result of phonetic implementation at the phonetic level, P. With the framework of Cognitive Phonology, a construction of Post Obstruent Tensification is proposed in such a way that rule-ordering is eliminated. This enables us to overcome methodological problems raised in former analyses of fortis under geminate hypothesis, and give a uniform account for three categories of fortis consonants. By assuming extrasyllabicity of verb-stem-final, consonant neutralization of fortis in the coda position is explained by the invisibility at the P-level. and, therefore. modification of Coda Neutralization rule is called for.

Grover 양자 알고리즘은 brute-force attack 가속화로 대칭키 암호의 보안 강도를 크게 감소시키므로 기존 블록 암호가 양자 컴퓨터에 안전하지 않을 것이라 예상한다. 따라서 대상 암호에 대한 양자회로 구현을 통해 Post-quantum 보안 강도를 확인하여 대규모 양자 컴퓨터 시대에 대비할 수 있다. 본 논문에서는 모든 SIMECK 경량 암호군에 대해 양자 자원(큐비트, 양자 게이트)을 최소화 한 기법으로 설계된 최적의 양자회로 구현 결과를 제시하고 각 함수별 양자 회로 동작을 설명한다. 마지막으로 제안된 SIMECK 양자회로에 대한 양자자원 추정 결과를 SIMON 양자 회로 결과와 비교하고 Grover 공격 비용을 계산하여 SIMECK 경량암호의 Post-quantum 보안 강도를 평가한다. Post-quantum 보안 강도 평가 결과 모든 SIMECK 경량 암호군이 NIST 보안 강도에 도달하지 못했다. 따라서 대규모 양자 컴퓨터 등장 시 SIMECK 암호의 안전성이 불명확하다고 예상하며 이에 대해 본 논문에서는 보안 강도를 높이기 위한 방안으로 블록사이즈 및 라운드 수와 키 길이를 증가시키는 것이 적합하다고 판단한다.

The impact of income and education level on the clinical and pathologic characteristics, implementation of clinical breast examination (CBE), and treatment patterns of a small population of Chinese female breast cancer patients was studeied in order to provide a theoretical basis and statistical reference for further nationwide research. We included 484 pathologically confirmed female primary breast cancer inpatients of the First Affiliated Hospital of Medical College of Xi'an Jiaotong University from February 2003 to January 2004. All cases were reviewed and relevant information was collected using a designed case report form (CRF). Chisquare tests, rank-sum tests, and Fisher's exact tests were used in the analysis. Our analysis showed that: (1) women in different occupation groups had significant differences in tumor size, pre-operative mammography, surgical options, post-operative estrogen receptor (ER), progestin receptor (PR) and human epidermal growth factor receptor 2 (Her2) status, and post-operative radiotherapy and chemotherapy (P < 0.05); and (2) women with different education levels had statistically significant differences in tumor size, post-operative ER, PR and Her2 status, and post-operative chemotherapy, radiotherapy, and endocrine therapy (P < 0.05). In Xi'an, China, women in low-income occupations or with low education levels are more likely to have advanced tumor stages at presentation, lower implementation rate of clinical breast examination, and less treatment.

양자 컴퓨터의 시대가 점점 현실로 다가오고 있다. 이에 대비해 미국 국립 표준 기술 연구소에서는 양자 알고리즘으로부터 내성이 있는 양자 내성 암호의 표준을 정하기 위해 후보군을 모집했다. 제출된 암호들은 양자 알고리즘으로부터 안전할 것으로 예상이 되지만 알고리즘이 실제 양자 컴퓨터상에서 작동이 되었을 때에도 양자 알고리즘의 공격으로부터 안전한지 검증을 할 필요가 있다. 이에 본 논문에서는 부호 기반 양자 내성 암호의 이진 필드 상에서의 곱셈 연산을 양자 컴퓨터에서 작동될 수 있게 양자 회로로 구현하였고 해당 회로를 최적화 하는 방안에 대하여 설명한다. 구현은 대표적인 부호 기반 암호인 Classic McEliece에서 제시하는 2개의 필드 다항식과 ROLLO에서 제시하는 3개의 필드 다항식에 대하여 일반 곱셈 알고리즘과 카라추바 곱셈 알고리즘으로 구현하였다.

Purpose: The purpose of this study was to evaluate the effectiveness of pulmonary rehabilitation on lung function and fatigue in persons with chronic obstructive pulmonary disease (COPD). Methods: Thirty one persons with COPD participated in this study. Four groups were allocated as follows: experimental group 1 (under 10 years of the post-disease period), control group 1 (under 10 years of the post-disease period), experimental group 2 (over 10 years of the post-disease period), and control group 2 (over 10 years of the post-disease period). Results: Forced expired volume in one second (FEV1) % pred and lactic acid showed improvement in experimental group 1 and experimental group 2 after training. Control group 1 and control group 2 did not show improvement of FEV1% pred and lactic acid after training. However, FEV1% pred and lactic acid in experimental group 1 were not significantly different, compared with the experimental group. Conclusion: Results of our study suggest that implementation of a pulmonary rehabilitation program resulted in improvement of lung function and fatigue in persons with COPD not related to the post-disease period.

An important technique of the present invention is primarily to parallel light detection, self-pulse therapy after diagnosis. Herpes zoster is a disease caused by varicella zoster virus, and the virus that has been latent in the dorsal root ganglion that controls the skin segment loses its immune system and physically damages it. It is an acute skin disease in which acute pain and bullous rash occur along the sensory ganglia, which are rehab by inducers such as malignant tumors. Dorsal root ganglion after complete recovery of varicella, relapsed after incubation in brain ganglion, latent virus sometimes suppressed activity by cell mediated immunity, and in cell ganglion with reduced cellular immunity. It proliferates and destroys neurons, causing pain while forming a rash and blisters. This can reduce cell necrosis and increase the phagocytosis and enzymatic activity through the movement of ions through the cell membrane, depolarization and membrane potential change, growth factor secretion, calcium ion transfer, chondrocyte synthesis, etc., And may offer treatment options for lesions of herpes zoster and post-herpetic neuralgia (PHN).Therefore, according to the present research, the diagnosis and treatment device of treating paing for herpes zoster and post-herpetic pain can be implemented in the early stage of herpes zoster, and conventional analgesic regulation, anti-inflammatory effect, post-herpetic neuralgia.
