Gymnodinium mikimotoi is one of several species of flagellates that cause harmful red tides. The red tides of G. mikimotoi have occurred only along $33-35^{\circ}$ N, e.g. Chinhae Bay in Korea, tile Seto Inland Sea and Kumane-Nada in Japan. I try to reproduce the formation of red ties of G. mikimotoi at Suo-Nada and Iyo-Nada, the western part of Seto Inland Sea, Japan in July 1985 with the use of four-dimensional assimilation model including the biological process of G. mikimotoi in this paper.

By comparing ‘Jing Mai(${\ulcorner}$經脈${\lrcorner}$)’ and ‘Jin Fu(${\ulcorner}$禁服${\lrcorner}$)’, we are able to see that ‘Jing Mai’ has adopted many of its aspects from ‘Jin Fu’, which also enables us to conclude that ‘Jing Mai’ was made after 'Jin Fu', with the 'Ren Ying Cun Kou Mai Fa(人迎寸口脈法)‘ being considered important. 'Jing Mai' was made relatively late, during the last days of 'Xi Han(西漢)' or early days of 'Dong Han(東漢)'. Also 'Jing Mai' was written after 'Ying Qi(${\ulcorner}$營氣${\lrcorner}$)’. ‘12 Jing Mai’ in ‘Jing Mai’ is based mainly on 'Yin Yang Shi Yi Mai Jiu Jing(${\ulcorner}$陰陽十一脈灸經${\lrcorner}$)‘ and has also referred to other meridian theories, modifying it again by theories of 'Jin Fu' and 'Ying Qi', forming the 'Jing Mai Lian Huan(經脈連環)' part. The major change in '12 Jing Mai' is that '6 Yang Jing(6陽經)' enters the abdominal and thoracic cavity, directly relating to 'Liu Fu(六腑)'. 'Ben Jing(本經)'s connection to 'Ben Zang' is referred to as 'Shu(屬)' and connection to 'Ben Zang(本臟)' is referred to as 'Lou(絡)', clarifying 'Biao Li Guan Xi(表裏關系)' inside and outslde and 'Zang Fu Xiang He(臟腑相合)' congruency. Looking at the pathological condition view of ‘Jing Mai’, the writer of 'Jing Mai Pian' has renewed it and has erased repeated symptoms of 'Suo Seng Bing(所生病)' that appears in 'Shi Dong Bing(是動病)'. If the wrong adoption of theories of previous generations are corrected and parts which do not comply with the text's original meaning and parts that posterities added are deleted, the ancient acupuncture theory preserved in this book is still a precious treasure.

In this paper, an auxiliary winding driving system of single-phase induction motors is described. Starting charateristics variations are obtained by controlling the auxiliary winding voltage magnitude and phase angle, while the motor's main winding is directly connected to the local utility. A variable auxiliary winding voltage phase angle is shown to yield significant torque control, providing starting and braking torque. The analysis includes the determination of the relationship between the auxiliary winding voltage phase angle and the phase angle difference between the main and auxiliary winding current. The paper proposed for adjusting an auxiliary winding voltage magnitude and phase angle. Experimental results of motor's starting characteristics with using the DC-AMP and PWM inverter for auxiliary winding power supply are shown. The drive is tested using a dynamometer to experimentally verify the results of the theory.

The purpose of this study is to investigate the characteristics of electroencephalogram (EEG) during emotional occurrence of likes and dislikes in humans subjected to visual stimuli. Fifteen healthy male subjects participated in the study. Portrayals of females and cars on a visual screen, one photographic display at a time. were used as the stimulus. The subjects, with their EEGs concomitantly monitored, were asked to record their likes and dislikes for each portrayal of a total of 50 sequential displays. The results indicated that beta ($\beta$)=wave was more prevalent with dislikes than likes, and the arousal level was higher when dislikes predominated over likes, implying that more cerebral information processing activity was involved in answering dislikes than likes. In the case of cars, the difference between likes and dislikes was focused within a frequency band of 15-20 Hz in the right cerebral hemisphere. Our findings suggest that the activity in the right brain predominates with increases in negative emotion.

In this paper, we present a new approach for speaker diarization. First, we use the prosodic information calculated on the original speech to resynthesize the new speech data utilizing the spectrum modeling technique. The resynthesized data is modeled with sinusoids based on pitch, vibration amplitude, and phase bias. Then, we use the resynthesized speech data to extract cepstral features and integrate them with the cepstral features from original speech for speaker diarization. At last, we show how the two streams of cepstral features can be combined to improve the robustness of speaker diarization. Experiments carried out on the standardized datasets (the US National Institute of Standards and Technology Rich Transcription 04-S multiple distant microphone conditions) show a significant improvement in diarization error rate compared to the system based on only the feature stream from original speech.

With the increasing application of explosive composite structure in many engineering fields, its interface bonding state detection is more and more significant to avoid catastrophic accidents. However, this task still faces challenges due to the complexity of the bonding interface. In this paper, the concept of nonlinear output frequency response functions (NOFRFs) is introduced to detect the bonding state of explosive composite structure. The NOFRFs can describe the nonlinear characteristics of nonlinear vibrating system. Because of the presence of the bonding interface, explosive composite structure itself is a nonlinear system; when bonding interface of the structure is damaged, its dynamic characteristics show enhanced nonlinear characteristic. Therefore, the NOFRFs-based detection index is proposed as indicator to detect the bonding state of explosive composite pipes. The experimental results verify the effectiveness of the detection approach.

A method to measure the interfacial toughness of film/substrate by nanoindenter is proposed. As the thickness of the film decreases, the measurement of the interfacial toughness requires the more sophisticated equipment such as nanoindenter. In this study, the nanoindenter is applied to the substrate near the interface of film/substrate in the direction perpendicular to the normal of the interface, causing the cohesive fracture of the substrate, followed by the interfacial cracking. The specimen of Cu($0.56 {\mu}m$)/Si(530 ${\mu}$) are made by sputtering the copper onto the silicon wafer. By scratching the copper surface, we can make the easy interfacial cracking during the nanoindentation. It is found that the averaged values of the interfacial toughness of the Cu/Si is $0.664{\pm}0.3\;J/m^2$ . The phase angle of the specimen in this study is ${\psi}{\simeq}-36.8^{\circ}$, computed by the method of Suo and Hutchinson.[1]

본 논문에서는, 가상 전장 시나리오에서의 방어 전략 시스템에서 지능형 서비스를 구축하기 위한 핵심으로 군 도메인 온톨로지를 구축하고자 한다. 군대에서는 과거와 비교할 수 없는 다양하고 복잡한 데이터가 존재하는 상황에서 그 데이터를 지능적, 효율적으로 처리하기 위한 요구가 대두되고 있다. 이를 해결할 수 있는 방안의 하나로써 정보의 지식화가 있으며, 온톨로지는 도메인에서 개념과 관계를 표현할 수 있는 지식 표현 방법이다. 군 도메인 온톨로지는 추후 도메인 간의 호환성을 위한 상위 온톨로지인 SUMO (Suggested Upper Merged Ontology)를 사용하였고, 상위 온톨로지와 도메인 온톨로지를 연결해주는 중간 레벨 온톨로지인 MILO (Mid-Level Ontology)를 사용하며, 온톨로지 표현 언어로 SUO-KIF를 사용하여 개발되었다. 추후 군 도메인 온톨로지는 멀티에이전트 기반 방어 전략 시스템이 돌아가는 Cougaar Framework에서 사용될 수 있도록 고려되었다.

본고에서는 <수오재기(守吾齋記)>의 내용을 분석한 후, 이 작품의 특징과 의미가 무엇인지를 먼저 살펴보고, <수오재기>를 가지고 교육적으로 활용할 수 있는 방안을 고찰하였다. <수오재기>의 내용을 보면 정약현이 정약용과는 달리 자기를 지키는 집에서 계속 살고 있는 것 또한 '나'를 잃지 않고 지조를 지킨 덕분이라고 말하면서 '나'를 잃어 버려 지금 장기에 유배를 온 자기와는 다르다고 얘기하고 있다. 즉, <수오재기>에서는 정약현을 통해 '나'를 지키는 것이 무엇인가를 보여주고 있다. <수오재기>의 특징과 의미에서는 정약용이 한문양식 중 하나인 '기(記)'를 매개로 하여, 귀양지에서 본질적 자아인 나와 대화를 나누는 등 표현상의 독창성을 보여주고 있다. 그리고 <수오재기>는 나의 모습을 되돌아보는 것으로 반성과 성찰의 행위를 가시적으로 보여주고 있는 작품이다. <수오재기>의 교육적 활용에서는 자(字)와 호(號)를 짓는 방법과 자기소개서 쓰는 것을 학생들 교육에 활용하고자 한다. 자와 호를 짓도록 하는 것이 현실에서는 실효성이 적지만 어떻게 짓는가를 알려주어 선인들이 자와 호를 짓는 의미를 파악하기 위함이다. 자기소개서는 요즘 학생들에게 필요한 것인데, <수오재기>에서처럼 '나'를 먼저 파악한 후에 자신을 다른 사람에게 알리면 그 효능이 클 것이다. 이를 교육에 활용하면 국어교육에 효과가 클 것으로 기대된다.
