The Fukushima-Daiichi accident shook the world, as a well-known plant design, the General Electric BWR Mark I, was heavily damaged in the tsunami, which followed the Great Japanese Earthquake of 11 March 2011. Plant safety functions were lost and, as both AC and DC failed, manoeuvrability of the plants at the site virtually came to a full stop. The traditional system of Emergency Operating Procedures (EOPs) and Severe Accident Management Guidelines (SAMG) failed to protect core and containment, and severe core damage resulted, followed by devastating hydrogen explosions and, finally, considerable radioactive releases. The root cause may not only have been that the design against tsunamis was incorrect, but that the defence against accidents in most power plants is based on traditional assumptions, such as Large Break LOCA as the limiting event, whereas there is no engineered design against severe accidents in most plants. Accidents beyond the licensed design basis have hardly been considered in the various designs, and if they were included, they often were not classified for their safety role, as most system safety classifications considered only design basis accidents. It is, hence, time to again consider the Design Basis Accident, and ask ourselves whether the time has not come to consider engineered safety functions to mitigate core damage accidents. Associated is a proper classification of those systems that do the job. Also associated are safety criteria, which so far are only related to 'public health and safety'; in reality, nuclear accidents cause few casualties, but create immense economical and societal effects-for which there are no criteria to be met. Severe accidents create an environment far surpassing the imagination of those who developed EOPs and SAMG, most of which was developed after Three Mile Island - an accident where all was still in place, except the insight in the event was lost. It requires fundamental changes in our present safety approach and safety thinking and, hence, also in our EOPs and SAMG, in order to prevent future 'Fukushimas'.

In this paper, the deep convolutional neural network for sound event detection is studied. Especially, the end-to-end neural network, which generates the detection results from the input audio waveform, is studied for weakly supervised problem that includes weakly-labeled and unlabeled dataset. The proposed system is based on the network structure that consists of deeply-stacked 1-dimensional convolutional neural networks, and enhanced by the skip connection and gating mechanism. Additionally, the proposed system is enhanced by the sound event detection and post processings, and the training step using the mean-teacher model is added to deal with the weakly supervised data. The proposed system was evaluated by the Detection and Classification of Acoustic Scenes and Events (DCASE) 2019 Task 4 dataset, and the result shows that the proposed system has F₁-scores of 54 % (segment-based) and 32 % (event-based).

This research centers on studying the function and characteristic of fashion illustration for advertisement and publication which is, among plenty of fashion illustration's functions, the commercial one. Here are some purposes of the research. First, it presents the function of fashion illustration. Second, under the contemporary circumstance of specialization and subdivision. It givers people the better understanding of fashion illustration by providing a variety of its classification bases other than the typical, simple grouping of style drawing and fashion illustration. Third, this research helps fashion illustration establish itself as commercial art by showing how fashion illustration is utilized in the field as a part of the fashion industry. The methods and contents of the research are described that the concept of fashion illustration, characteristic, classification bases and commercial function are presented and than the data of fashion illustration which hale been used as goods since 1990 in the nation are selected in order to analyze the media for the application of fashion illustration. its expression methods, factors and images. By doing so, advertising fashion illustration are much less than those of published fashion illustration and even most cases of advertising fashion illustration are related just to poster advertisement such as magazines, fashion events or public subscription. The published fashion illustration isn't also attracting the public since it focuses on fashion information books, fashion magazines or fashion -clothing books. Another finding is that the expression style of fashion illustration is not various or distinctive. The expression remains in the trends of painting, figurative drawing, sometimes adopts post-modernism which is reflected in popular cartoon and figures exaggerates or simplifies the human body. The image of fashion illustration is simple. casual or feminine in the rough. For the development of commercial fashion illustration, it is required to produce fashion illustrators, not works but goody, with various concepts appealing to the public.

PURPOSE: This study examined the differences in the trunk impairment scores according to the levels of the gross motor classification system by evaluating trunk control in children with spastic cerebral palsy using the index of trunk impairment. In addition, the characteristics of trunk control disabilities were investigated according to the cerebral palsy type. METHODS: The subjects were 49 children (mean age 8.57±1.83 years, 11 with hemiplegia, 26 with diplegia, and 12 with quadriplegia) with spastic cerebral palsy levels I to IV under the gross motor function classification system (GMFCS). The coordination and balance of the children with cerebral palsy were evaluated using the index for trunk impairment. Statistical analyses were performed using a Kruskal-Wallis test, and Bonferroni analyses were used as a post-hoc comparison for any significant results. RESULTS: The median of the total scores of trunk impairment was 13 (range, 9-17), which was 56% of the maximum score. The total score of trunk impairment and subscales differed significantly according to the disease severity and type of motor disability. The scores for children with quadriplegia were the lowest compared to children with hemiplegia and diplegia. CONCLUSION: Trunk control function in children with spastic cerebral palsy was reduced, and varied according to the disease severity and types of motor disabilities. The degree of trunk impairment differed from the trunk control ability according to the degree of motor disability of children with cerebral palsy.

Objective : Recently, the survival of patients with hepatocellular carcinoma (HCC) has been prolonged with improvements in various diagnostic tools and medical treatment modalities. Consequently, spine metastases from HCC are being diagnosed more frequently. The accurate prediction of prognosis plays a critical role in determining a patient's treatment plan, including surgery for patients with spinal metastases of HCC. We investigated the clinical features, surgical outcomes, and prognostic factors of HCC presenting with spine metastases, in patients who underwent surgery. Methods : A retrospective review was conducted on 33 HCC patients who underwent 36 operations (three patients underwent surgical treatment twice) from February 2006 to December 2013. The median age of the patients was 56 years old (range, 28 to 71; male : female=30 : 3). Results : Overall survival was not correlated with age, sex, level of metastases, preoperative Child-Pugh classification, preoperative ambulatory function, preoperative radiotherapy, type of operation, administration of Sorafenib, or the Tokuhashi scoring system. Only the Tomita scoring system was shown to be an independent prognostic factor for overall survival. Comparing the Child-Pugh classification and ambulatory ability, there were no statistically differences between patients pre- and post-operatively. Conclusion : The Tomita scoring system represents a practicable and highly predictive prognostic tool. Even though surgical intervention may not restore ambulatory function, it should be considered to prevent deterioration of the patient's overall condition. Additionally, aggressive management may be needed if there is any ambulatory ability remaining.

Objectives: The purpose of this study was to examine the psychological factors of Sasang constitutions which are classified by QSCC II(Questionnaire for Sasang Constitution Classification II) using major personality tests which are based on western psychological theory. Methods: 151 college students completed the MMPI-2, MBTI, NEO-PI-R, TCI-RS, and QSCC II. The data were analyzed by ANOVA and post hoc testing to find which personality scale significantly differentiated each Sasang constitution style. Results: MMPI-2, scale 2(D), 5(Mf), 7(Pt), 0(Si) and introversion scale(INTR) showed significant differences between Soeumin and Soyangin. Also, on the dimension of introversion-extraversion in MBTI, and neuroticism(N) and extraversion(E) in NEO-PI-R, there were differences between Soeumin and the other two constitutions(Soyangin and Taeeumin). Finally, in TCI-RS, there were differences between Soeumin and Soyangin on the scale of novelty seeking(NS) and reward dependence(RD), and with regards to the harm avoidance scale(HA), Soeumin received a higher score than any other constitutions. Conclusions: The analysis demonstrates that the classification of QSCC II is most consistent between Soeumin and Soyangin across 4 major personality tests.

Purpose: Perceiving the experience that $MRD_1$ is increased after small-incision double-eyelid operation, it has been statistically verified the improvement of $MRD_1$ retrospectively. Therefore, we suggest new interpretation for Korean-specific small eye and more definite classification for ptosis. Methods: In operation, we made 3 small incisions according to the line designed on upper eyelid and removed some soft tissues including connective tissues. Then, figure-of-8 continuous buried ligation was performed through the incision windows. This study is a retrospective study, measures $MRD_1$ changes and excursion distance change of eyelid margine and eyebrow using pre-and post-operative photos of 14 patients. Results: Postoperative photos were taken on the 4th day and all of 14 patients had an improvement in $MRD_1$ statistically. The excursion distance of upper eyelid was improved in half of patients, though not in the range of statistical verification. It was statistically confirmed that the movement of eyebrow was reduced after operation. Conclusion: It is thought that $MRD_1$ improvement without any operation on levator complex means that soft tissue including connective tissue eliminated in operation restricts the movement of upper eyelid. It is defined such factors as burden factors and such phenomenon as burdened eyelid. It is thougt that Korean's small eye is mainly burdened eyelid and cosmetic improvement may be obtaind even by removing such burden factors.

Background Aggressive treatment of sternoclavicular joint (SCJ) infection involves systemic antibiotics, surgical drainage and resection if indicated. The purpose of this paper is to describe a classification of post resectional SCJ defects and highlight our reconstructive algorithm. Defects were classified into A, where closure was possible often with the aid of topical negative pressure dressing; B, where parts of the manubrium, calvicular head, and first rib were excised; and C, where both clavicular, first ribs and most of the manubrium were resected. Methods Twelve patients (age range, 42 to 72 years) over the last 8 years underwent reconstruction after SCJ infection. There was 1 case of a type A defect, 10 type B defects, and 1 type C defect. Reconstruction was performed using the pectoralis major flap in 6 cases (50%), the latissimus dorsi flap in 4 cases (33%), secondary closure in 1 case and; the latissimus and the rectus flap in 1 case. Results All wounds healed uneventfully with no flap failure. Nine patients had good shoulder motion. Three patients with extensive clavicular resection had restricted shoulder abduction and were unable to abduct their arm past $90^{\circ}$. Internal and external rotation were not affected. Conclusions We highlight our reconstructive algorithm which is summarised as follows: for an isolated type B SCJ defect we recommend the ipsilateral pectoralis major muscle for closure. For a type C bilateral defect, we suggest the latissimum dorsi flap. In cases of extensive infection where the thoracoacromial and internal mammary vessels are thrombosed, the pectoralis major and rectus abdominus cannot be used; and the latissimus dorsi flap is chosen.

The major challenge for post-genomic study is to identify structural similarity and relationships of proteins. SCOP (Structural Classification of Proteins) is a typical database for this purpose, providing a derailed description of the structural and functional relationships of the proteins whose three-dimensional structures have been determined. Unfortunately, since the SCOP data is only available as a plain text format, it is cumbersome and error-prone to develop tools and resources to utilize the data more effectively. To meet these researchers to utilize the data more effectively. To meet these requirements, we have developed an XML representation for the SCOP site, users of the tool, named, SCOPBrowser, for effective search of SCOP database. In addition to the information available from the SCOP site, users of the tool can obtain various information such as viewing the tree hierarchy of structure classification of proteins, searching into whole protein domains, showing XML contents of a specific domain, and some useful statistics about protein structures.
