One of the cause of insulation failure in power cable is well known by electrical treeing discharge. This is occurred for imposed continuous stress at cable. And this event is related to safety, reliability and maintenance. In this paper, throughout analysis of partial discharge(PD) distribution when occurring the electrical tree, is studied for the purpose of knowing of electrical treeing discharge characteristics according to defects. Own characteristic of tree will be differently processed in each defect and this reason is the first purpose of this paper. To acquire PD data, three defective tree models were made. And their own data is shown by the phase-resolved partial discharge method (PRPD). As a result of PRPD, tree discharge sources have their own characteristics. And if other defects (void, metal particle) exist internal power cable then their characteristics are shown very different. This result Is related to the time of breakdown and this is importance of cable diagnosis. And classification method of PD sources was studied in this paper. It needs select the most useful method to apply PD data classification one of the proposed method. To meet the requirement, we select methods of different type. That is, neural network(NN-BP), adaptive neuro-fuzzy inference system and PCA-LDA were applied to result. As a result of, ANFIS shows the highest rate which value is 98 %. Generally, PCA-LDA and ANFIS are better than BP. Finally, we performed classification of tree progress using ANFIS and that result is 92 %.

The 16S rRNA analyzing method is a bacterial identification method that is useful in identifying bacteria which is difficult to do by other means. The following 7 types of bacteria which are Treponema, A. actinomycetemcomitans, P. gingivalis, Fusobacterium, B. forsythus, P. intermedia, P. micros were evaluated in order to study their distribution among patients with adult periodontitis. The 16S rRNA analyzing method was used to compare bacterial distribution among 3 groups. Subgingival plaque acquired from the affected sites(pocket depth ${\geq}6mm$) of 29 patients with adult periodontitis were grouped as the experimental group while plaque from the non-affected sites(pocket depth ${\leq}3mm$) were grouped as control 2 and finally plaque acquired from students with healthy periodontal tissues were grouped as control 1. The results are as follows ; 1. The distribution of Treponema was 12.5% for control 1, 21.4% for control 2 and 75.4% for the experimental group. For A. actinomycetemcomitans the distribution was 0.5%, 19.0%, 44.4% in respect to the order of groups mentioned above. P.gingivalis showed 10.5%, 43.1%, 94.0% distribution, Fusobacterium 33.0%, 48.3%, 81.0% distribution, B. forsythus 9.5%, 17.2%, 65.9% distribution, P. intermedia 1.0%, 12.1%, 26.3% distribution and finally P. micros 5.0%, 19.0%, 48.7% respectively. In all 7 types of bacteria, the experimental group showed higher bacterial distribution compared to the other two groups with statistically significant difference. 2. In the case of Treponema, A. actinomycetemcomitans, gingivalis,Fusobacterium, B. forsythus, P. intermedia, P. micros showed significant difference between control 1 and 2. These results suggest that the 16S rRNA analyzing method which was applied on Koreans for the first time could be utilized and useful in finding potential pathogens of periodontal disease.

견인전동기용 고정자 코일의 Off-line 부분방전 진단을 위한 NN의 적용

박성희,임기조,강성화,Park, Seong-Hee,Lim, Kee-Joe,Kang, Seong-Hwa 한국전기전자재료학회 2005 전기전자재료학회논문지 Vol.18 No.8

In this study, PD(partial discharge) signals which occur at stator coil of traction Motor are acquired these data are used for classifying the PD sources. NN(neural network) has recently applied to classify the PD pattern. The PD data are used for the learning process to classify PD sources. The PD data come from normal specimen and defective specimens such as internal void discharges, slot discharges and surface discharges. PD distribution parameters are calculated from a set of the data, which is used to realize diagnostic algorithm. NN which applies distribution parameters is useful to classify the PD patterns of defective sources generating in stator coil of traction motor.

Purpose : The objective of this study is to ascertain whether the positive exists among the frenum length, the tongue movement and the speech and to present the normal range of tongue movement and guidelines for the choice of surgery, observation if necessary. Materials and Methods : 180 patients were evaluated. We divided 180 patients into 6 group by age. Each group was separated as follows; the age of 2.5-4, 5-6, 7-9, 10-12, 16-18. We measured the frenal length, the range of tongue motion and evaluated the speech so that we really questioned about the positive relationship between the tongue-tie and speech. We let the patient exercise the protrusive both(right, left) laterotrusive superior movement of the tongue. During these movements, we measured the distance between the vermilion border and the tongue tip. We also measured the distance from the tongue tip to the point contacting the upper lip with dorsum of the tongue during the maximal protrusive movement of the tongue. Three linear measurement of the anterior, inferior segment of the tongue including the lingual frenum, are made. These measurements are as follows: 1. Distance A. Free anterior portion of the tongue from the point of frenular insertion to the tongue tip. 2. Distance B. The distance from the initiating point of the lingual frenum to the point connecting the two sublingual carundcles to the lingual frenum perpendicularly. 3. Distance C. The distance from the point contacting the line crossing the sublingual caruncles with the lingual frenum to the terminating point of the lingual frenum. We transform three linear measures into a statistical ratio, A/(A-B+C), representing the length of the free portion of the tongue compared with the total sublingual dimensions. In addition, we assessed the speech through Picture Consonant Articulation Test(PCAT) and tried to find out the relationship between the length of the lingual frenum and speech. Conclusion : As people are born, they have small and restricted tongue. As people grow old, tongue motions are more liberate, and unrestricted and they can speak so freely. Therefore we suggest that until age 5, oral and maxillofacial surgeons postpone the surgery if not urgent, evaluate the maximal lingual motions and PCAT according to this article and observe their changes.

中野重治の「五勺の酒」論 〈末練〉について再考する

'Five Scoops of Liquor'(Nakano Sigeharu) is a short novel published in the January issue of 『展望』 in 1947, right after being defeated in World War Ⅱ. This piece of work is what we call an epistolary novel, in which a principal in the teaching profession of a secondary school under the old system writes letters to his friend. He has a few drinks (Rationed liquor by the Constitution) and gives vent to his pent up fury, anger, and frustration against the post war circumstances of society and life. He was just a teacher who wanted to "stay with his young students and go with them, though moving slowly along on hands and knees, and wanted to give encouragement and guidance to them." He prayed to stay with the boys, with his everything at risk. But he couldn't do anything for them at war. Far from 'being with them, though moving along on hands and knees', he could not help seeing his students and young fellows leaving for battlefields. This engraves a deep feeling of sin, remorse, and a sort of lingering attachment that can't be cut out or abandoned in his heart. A deeply engraved lingering attachment or regret does adhere to him and will not get away from his mind, because it is related to 'a lingering attachment or regret for the future', rather than ending up with 'a sentiment for the past that can not be undone'. This hazy feeling of lingering attachment or regret makes him heartbroken. From the start of having this feeling, he cannot but stare at his inside, of which confusion makes him stagger uncontrollably. The sin that a lot of Japanese, including him, might have felt or committed at war will not be brought to the public as a national unsettled issue nor be treated substantially. This dismal foreboding of the future makes his mind become more and more chaotic. The start line of dealing with or correcting the past wrongdoings should be from clarifying the reason why the past turned out to be. Otherwise, we can't make our new future. 'A Practical Hope' lies in making the reasons clear. His sin turns out to be a foundation of postwar Japan, without taking any responsibility of the war. This ominous presentiment overlaps the promulgation of a new constitution that can be a postwar symbol. Those situations make him desire to get drunk and run away. Nevertheless, his feeling of lingering attachment has a factor of significance that can be referred to as 'Practical Hope'. It is because every country has its own painful and remorseful history, and we believe that a bright prospect can be made on our truthful and ardent effort to find a ray of hope in feelings of lingering attachment, remorse, despair, and dismal history stained with pain. It may be that a practical hope will come true in the midst of connecting the past of wrongdoings with the resultant present without discontinuity.

사찰음식의 지혜

박성희(Park, Seong-hee) 한국불교상담학회 2021 불교상담학연구 Vol.16 No.-

사찰에서의 음식 문화는 대중 생활의 측면과 수행 생활의 측면에서 질서 있고 체계적으로 발달해 왔다. 특히 한국불교의 수행 음식은 제철 식재료를 활용한 전통음식의 일부이며 오신채를 배제한 건강식이다. 전 세계적으로 사찰음식이 주목을 받고 있는 이 시대에 한국 사찰 문화의 라이프 스타일이 주목받고 있는 이유를 연구해 볼 필요가 있다. 사찰음식은 산문을 나서면서부터 사찰음식으로서의 본질이 퇴색되기 마련이지만 근본 바탕에 대한 이해가 분명하다면 충분히 많은 사람들에게 울림을 줄 수 있는 치유 음식이 될 수 있다. 산문을 나선 사찰음식이 역병을 치유하는 건강식, 수행식, 지혜식임을 체험하고 공유하다 보면 저절로 치유의 음식으로 거듭날 것이다. 사찰음식은 영양의 불균형을 해소한 음식이다. 제철 음식을 기반으로 하여 곡류와 산채를 이용하여 잘 발효된 장을 활용해 간단한 조리를 한다. 청정, 유연, 여법함을 잃지 않고 몸을 지탱하는 약으로 음식을 취한다. 사찰음식은 건강음식의 대명사가 되었고 채식 위주의 식단으로 불균형을 이룰수 있는 영양적인 면도 지혜롭게 해결하고 있다. 지독한 역병으로 전 세계가 흔들리고 있는 이 시점에서 자연의 에너지, 땅의 에너지가 우리를 어떤 식으로 치유하는지, 우리 몸의 에너지가 어떤 식으로 움직이는지, 자연의 에너지를 통해 스스로를 치유하고 싶은 사람은 어떤 마음가짐을 가져야 하는지에 대해 깊이 고민하고 사유하며 살고자 노력하는 것, 이것이 바로 삼덕육미의 마음가짐이고 사찰음식의 밑바탕이다. 보다 면밀히 내 몸을 살피고 내 마음을 살피는 삶을 살아갈 수 있도록 우리 일상에서 나타나는 모든 일들을 수행으로 받아들여 해결하려는 노력이 필요하다. The food culture in Korean Buddhist temples has been developed systematically in the aspects of community life and practice. Especially, Korean temple food is healthy food which is cooked with ingredients in season and without the five pungent vegetables. Since temple food has lately attracted global attention, it is necessary to study about the reason of the attention. Temple food could be the healing food with proper understanding of its essence. It will be recognized as the healing food by experiencing the temple food as the food of healthy, practice and wisdom. Temple food solves the problem of nutrition imbalance. It is cooked with grains, wild plants and well-fermented sauces based on the ingredients in season. And it is considered as a medicine for the body. Thus, it can be said tht temple food is synonymous with healthy food. When an epidemic is prevalent, we have to give deep thought to how the natural energy heals the human beings, how the energy in the body works and what is the attitude of a man who wants to heal himself by using the natural energy. It is the basis of temple food. In order to live a life that is mindful of the body and mind, we have to consider everything in daily life as a practice.

「현존(現存)」 보다 강한 「불재(不在)」-송본청장(松本淸張)의 「어느 『고쿠라 일기』전」을 중심으로-

박성희 ( Park Seong-hee ) 한국일본근대학회 2018 일본근대학연구 Vol.0 No.59

『어느「고쿠라일기」전』(或る「小倉日記」傳』)은 마츠모토 세이초(松本淸張)의 단편소설로『미타문학(三田文學) 』1952년 9월호에 발표되어 다음 해 第28回 芥川賞을 수상했다. 『어느「고쿠라일기」전』은 소위 심경소설 역사소설 모델소설 전기소설 등으로 다양하게 해석될 수 있겠다. 이러한 해석들은 40대도 중반이 되어 직업작가로 전환하기 위한 방책과 고심에서 유래한 것으로 보인다. 단편이 중심이 된 것은 신진작가로 당연한 생존방편이기도 하고, 많은 작가들에게서 나타나는 초기 경향이기도 하다. 여러 부분에서 淸張의 의도된,「사실」과의 불일치가 드러난다. 이러한 작업은 작가의 창작의도와 연결되어 의미를 배가한다고 할 수 있다. 작품을 위한 강화나 생략의 장치. 차별과 격차 인간의 좌절감의 강화를 드러내는 장치라고 할 수 있다. 오랫동안 억압받아왔던 생활인의 경험에서 얻은, 리얼리티를 배가하기 위한 작가의 의도임을 알 수 있었다. 「현대의 조직 안에서 숨 쉬는 인간」은 주로 급사, 인쇄공, 신문사광고부, 군인의 모습으로「현대의 조직 안에서 숨」쉬어 왔던 자신을 표상하는 것이리라. 이러한 자전적 요소는 여러가지 표현으로「인간」그리기를 반복하여 언급한 淸張에게,「인간」자체를 이해하고 내면의 욕구를 응시하기 위한 토양이 되었음을 알 수 있었다. “The Legend of the Kokura-Diary” (「或『る小倉日記』傳」) is a short story written by Seicho Matsumoto (松本淸張), which was published in the September 1952 issue of Mita Bungaku (『三田文學』) and won the author the 28th Akutagawa Prize next year. There are various ways to approach the story. “The Legend of the Kokura-Diary” can be read as a psychological story, a historical story, a model story, and a biographical story. These readings might have derived from the author’s efforts and struggle to become a full-time writer in his mid 40s. It might be natural that the short story was his main genre because as a budding writer he had to make a livelihood by writing, and it is also a tendency found among many writers in their nascent stage of career. There are many incidents of the author’s intentional discrepancy in the story. In connection with the author’s intention, this can be a technique to reinforce the zest and significance of the story. It is a device for reinforcement or omission for the work, underscoring discrimination, gaps, and human frustration. It tells about the intention of the author to intensify or heighten the reality, which he had experienced from his life that had been suppressed for a long time. ‘The human being breathing in modern organizations’ perhaps represents the author himself, who has been ‘breathing in modern organizations’ in the form of an office boy, a printer, an employee at the newspaper advertising department, and a soldier. For Seicho who represented ‘human beings’ in diverse forms, these autobiographical elements provided the foundation to understand ‘a human being’ himself and look into his inner desires and anxieties.
