  • For many years, many pilots lost their lives and aircrafts due to GLOC(Gravity-induced Loss Of Consciousness). Due to the emergence of high-gravity maneuvering aircraft such as the F-16, F-15 and T-50, the automatic GLOC detection and recovery systems are necessary to increase the aircraft safeties even when the pilot loses his consciousness due to high-G maneuvering. This paper addresses the design of GLOC detection, warning and recovery algorithm based on a model of supersonic jet trainer. The system is solely controlled by the pilot's control input (i.e., control stick force) and aircraft status such as attitude, airspeed, altitude and so forth. And, moreover, it does not depend upon any pilot physiological condition. The test evaluation results show that the developed system supports the recovery of an aircraft from the unusual aircraft attitude and improves the aircraft safeties even when the pilot loses his consciousness due to high-G maneuvering.

  • An improved derivative thermometric titration apparatus designed around operational amplifiers is described which is capable of monitoring the small temperature change and of computing the derivatives for accentuation of the titration end point that is difficult to locate by extrapolation methods. The instrument is constructed of four commercial operational amplifiers. A use of dummy cell provides the subtraction means for compensation of the initial temperature and random temperature fluctuations with a resultant gain in signal-to-noise ratio. The successive differentiation action of the computer has been nearly "perfect," so that the two breaks (blank or starting and end point of the titration curve can be located with the precision of 0.2% by observing two peak points on the second derivative curve. Arrangements useful in obtaining such a good derivative response that is exactly proportional to the input signal are discussed. Plots of the enthalphogram and its derivatives are presented, with the results of several titrations used to evaluate the performance of the apparatus.

  • This paper presents an analysis on the optimal partitioning configuration of cache (memory) for meeting deadlines of periodic and aperiodic real-time task set. Our goal is not only to decrease the deadline missing ratio of each task by minimizing the task utilization, but also to allocate another tasks to idle spaces of cache. For this reason, we suggest an algorithm so that tasks could be allocated to cache segments. Here, the set of cache segments allocated tasks is called a cache partitioning configuration. Based on how tasks allocate to cache segments, we can get various cache partitioning configurations. From these configurations, we obtain the boundary of task utilization that tasks are possible to schedule, and analyze the cache optimal partitioning configuration that can be executed to minimize the task utilization.

  • Jeon Kwang(癲狂), term of oriental medicine, corresponds to psychopathy. This is recorded in the 22th chapter of Young Chu(靈樞). Jeon and Kwang come under Eum(陰) and Yang(陽) respectively. The symptoms of Jeon have silence, cry and giggle alternately, muttering, and so on. And those of Kwang have quick-tempered, absurd remarks, slander, and so on. The contents of this chapter are divided into three volumes. The first is descriptive of paroxysmal causes and various symptoms of Jean and methods of acupuncture and moxibustion. The second stales causes, symptoms, and remedy methods of Kwang. And the third describes about Pung Youk(風逆), Kweol Youk(厥逆), So Ki(少氣), and Tan Ki(短氣). A paragraph concerning of Mok Ja(目眥), so to speak side of pupil, is mentioned at the begginning of this chapter incomprehensibly. Si Ma(馬蒔) asserted that this one is not a pleonasm because mental condition is seen at Mok Ja. But Sa-Deok Jeong(程士德) decided this one doesn't relation to Jeon Kwang. In my opinion, both views have proprieties. It is in a controversy whether Jeon Kwang has somthing to do with Pung Youk, Kweol Youk, etc. Tan Pa(丹波) asserted that these don't have connection each other. But JI-Chong Jang(張志總) explained Jeon Kwang originates in Kweol Youk with a basis of So Mun(素門). It is difficult to judge which opinion is right, but I am of the opinion that paragraphs of Pung Youk and downward mentioned those of other chapter with a mistake in the process of transcription. On accout of not only shortage contents but also ancient writings of this chapter we cannot understand all about Jeon Kwang. In addition, each woodblock-printed book has different letters and every commentaries aren't the same. Till now, therefore, basic study hasn't been done enough to offer a foundation to the theory of medical treatment. The purpose of this study is to correct wrong letters, to take out right commentaries, and then to interpret the accurat meaning of this chapter. I think this bibliographic study is quite meaningful because of hardship to cure psychopathy in clinic as well as of a viewpoint of basic study. However as this thesis is insufficient, so I expect many studies come out later.

  • Maek Kyoung(Mai Jing, 脈經) is the first chinese specialized book of diagnostics written by Wang Hee(Wang xi, 王熙) from Seo Jin(xi jin, 西晉). He assorted the contents with pulse and medical examination from Nae Kyoung(nei jing, 內經), Nan Kyoung(nan jing, 難經), Sang Han Ron(shang han lun, 傷寒論) and Jung Jang Kyoung(zhong cang jing, 中藏經). And united with his own research, he explains medical examination and the way of talking the pulse by classifying into entrance and class. Maek Kyoung(Mai Jing, 脈經) was imported Korea by Ji Chong(zhi cong, 知聰) AD 561, and he passed through Ko Ku Ryeo(gao gou li, 高句麗) with Nae Wei Jeon(nei wai dian, 內外典), Yak Seo(yao shu, 藥書), Myung Dang Do(ming tang tu, 明堂圖) and Maek Kyoung(Mai Jing, 脈經) to be naturalized in Japan. This treatise make a special study of the second volume of the Maek Kyoung. It consists of the four chapters: Pyoung Sam Kwan Eum Yang E Sip Sa Ki Maek Je II(平三關陰陽二十四氣脈第一), Pyoung In Young Sin Mun Ki Ku Jeon Hu Maek Je E(平人迎神門氣口前後脈第二), Pyoung Sam Kwan Byoung Hu Byoung Chi Eui Je Sam(平三關病侯幷治宜第三), and Pyoung Gi Kyoung Pal Maek Byoung Je Sa(平寄經八脈病第四).

  • In this paper, we propose a new detection method called dual-cell combining (DCC) detection for the acquisition in time of spread spectrum codes in the presence of residual frequency offset (RFO). When the RFO exists, the correlation peak used for detection during the acquisition process is split into two neighboring peaks with smaller amplitudes, resulting in considerable degradation in the overall acquisition performance of conventional methods. In the DCC detection method, the decision variable for detection is formed by combining two consecutive correlator outputs so that the influence of the reduction in the correlation peak due to the RFO can be alleviated. Numerical results show that the DCC detection method can offer better mean-time-to-synchrouization performance than the conventional method based on the cell-by-cell detection.

  • Objective: The purpose of this study was to report the clinical effectiveness of Korean medicine treatment on FOLFOX-induced symptoms such as nausea and dizziness in a patient with recurrent advanced gastric adenocarcinoma. Methods: The patient was diagnosed with recurrent advanced gastric cancer and had FOLFOX-induced nausea and dizziness. The patient was treated with Samchulgunbi-tang and Banhasashim-tang for symptom management. The clinical outcomes were measured by National Cancer Institute Common Terminology Criteria for Adverse Event (NCI CTCAE) and a numeral rating scale (NRS). Results: After treatment, the patient's nausea and dizziness were relieved from NRS 9 to 2 and NRS 8 to 2 respectively. During and after treatment, no severe toxicities were detected on laboratory findings. Conclusion: This case study suggests that Samchulgunbi-tang and Banhasashim-tang may relieve symptoms of FOLFOX-induced nausea and dizziness.

  • Purpose: The purpose of this study was to investigate the job stress in home care nurses. Method: The subjects were 139 home care nurses of hospital in an urban cities. The data were collected from 26 Man to 27 June by self report adherence questionnaire. Job stress was measured using CHN-PWRSQ(Community Health Nurses Perceptions of Work-Related Stressors Questionnaire). Result: The average score of job stress was 60.8. There were significantly high levels of job stress in those who have less than 10 years office period, those who have less than 2000000 won monthly salary than in their counterparts. With regard to the level of job stress by item, 'driving long distance and traffic jam', 'risk of traffic accident', 'bad weather condition', 'uncooperative family members', and 'uncooperative client/patient' were higher than other items. The age and office period were negatively correlated with job stress. Conclusion: The average score of job stress was 60.8. 'driving long distance and traffic jam', 'risk of traffic accident', 'bad weather condition', 'uncooperative family members', and 'uncooperative client/patient' were higher than other items.

  • A novel frequency offset estimation scheme using a periodogram is proposed for orthogonal frequency division multiplexing (OfDM) systems. A conventional scheme proposed by Ren has a problem that the fractional and residual frequency offset estimation steps do not compensate for the difference between the real frequency offset and estimated integer frequency offset in the noise channel. So, the frequency offset estimation performance of Ren's scheme is degraded. In this paper, a frequency offset estimation scheme is proposed, which has a larger estimation range than that of the factional and residual frequency offset estimation steps in Ren's scheme. The proposed scheme can compensate for the difference between the real frequency offset and estimated integer frequency offset, unlike Ren's scheme. From the simulation results, we can observe that the performance of the proposed scheme is better than that of Ren's scheme.
