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.

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.

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.

"Saying good-bye before a dawn" is the poetry to which a turning point in the time from the Taisho last years to the Showa beginnings and Shigeharu Nakano's adolescence were announced time intermingled in all. I'd like to reconsider about the time-like circumstances and social phenomenon through this poetry by this publication. His Proletarian lyrics were published, and were compared with common Proletarian poems that expressed infertility and a dry cry. They were not just an exclamation of ideology. With regard to the history of poetry in modernity, they heighten contemporary sufferings to a fulfillment of emotion that common Proletarian poems ignored. His literary small adolescence sprouts up at the literary ground where the feeling poetry party in the Taisyo period is made the center, and is that it grew naturally. He connects with marxism thought and practice while coming into action by "Sinzinkai-New Man Society" and "marxism art workshop" in college days, and a poetic word starts to touch description of feelings and a thought gradually. He comes to be advancing towards the world of proletarian poetry further. On the other hand, the maturity process of his poetic word piles up and is repeating it in multistory way. A new poetic word is being created through various experience in his growth process. "Good-bye." "flower", "celluloid toy" a poetic word of etc. looked for a symbol about the time aspect which is being done and a social aspect. Shigeharu Nakano had the interest to something subtle truly as a proletarian poet. He finds out that a matter is being drawn valuably by the form of some level. His Proletarian poems that have lyrical, satiric and beautiful poetic words will always remind us of NAKANO, who has played a chief role in social-intercourse literature, and has been familiar with readers as a Proletarian poet.
