  • Cold-formed steel (CFS) sections are becoming an increasingly popular solution for constructing floors in residential, healthcare and education buildings. Their reduced weight, however, makes them prone to excessive vibrations, increasing the need for accurate prediction of CFS floor modal properties. By combining experimental modal analysis of a full-scale CFS framed building and its floors and their numerical finite element (FE) modelling this paper demonstrates that the existing methods (based on the best engineering judgement) for predicting CFS floor modal properties are unreliable. They can yield over 40% difference between the predicted and measured natural frequencies for important modes of vibration. This is because the methods were adopted from other floor types (e.g., timber or standard steel-concrete composite floors) and do not take into account specific features of CFS floors. Using the adjusted and then updated FE model, featuring semi-rigid connections led to markedly improved results. The first four measured and calculated CFS floor natural frequencies matched exactly and all relevant modal assurance criterion (MAC) values were above 90%. The introduction of flexible supports and more realistic modelling of the floor boundary conditions, as well as non-structural $fa{\c{c}}ade$ walls, proved to be crucial in the development of the new more successful modelling strategy. The process used to develop 10 identified and experimentally verified FE modelling parameters is based on published information and parameter adjustment resulting from FE model updating. This can be utilised for future design of similar lightweight steel floors in prefabricated buildings when checking their vibration serviceability, likely to be their governing design criterion.

  • For the dissemination of new and renewable energy, Korean government introduced a renewable portfolio standard (RPS) scheme in 2012 after terminating feed-in tariff (FIT) scheme that was introduced in 2004. With the RPS scheme, 64.7% of its own goal (95.7% in PV and 63.3% in non-PV) was achieved in 2012 and 67.2% of that (94.9% in PV, 65% in non-PV) was achieved in 2013. The deployment of PV systems met the goal very well and that of non-PV did not. Recently, Korean government revised the target year of supplying 10% electricity from new and renewable energy from 2022 to 2024 and released a couple of measures on PV area. Recent studies showed that the bankability of a project plays a key role for PV dissemination. Therefore, the dissemination should be assessed from the point of bankability under the RPS scheme and a little adjustment is necessary to achieve the goal. Especially, installing a small size PV (<100 kwp) system needs a minimum REC price or a FIT scheme. In non-PV area, permission process is a common bottleneck and the related regulation should be eased. In addition, to achieve the long term goal, an implementing scenario has to be prepared. Currently, the portion of the waste-gas energy originated from fossil fuel is too large among the new and renewable energy sources and the portion should be lowered or eliminated in the 10% of electricity supply goal. Seoul Metropolitan Government (SMG) has its own FIT scheme for PV dissemination from 2014 SMG and revised the PV tariff from 50 to 100 won/kwh in effective of 2015. It is worth to spread the other provinces.

  • 향후 NGN(Next Generation Network)은 패킷 기반의 QoS가 제공되는 네트웍으로 발전하고 있다. 본 논문에서는 MPLS 네트웍에서의 보다 효율적인 경로 선택에 관한 기법으로 Service interruption time을 줄이는 복구방법을 제안한다. 장애복구의 주요 성능 중의 하나인 복구자원사용의 효율성을 높이기 위해서 각 노드들 간의 state information을 fault detector 와 bandwidth broker가 서로 공유하여 장애 발생 시 복구를 위한 message transmission time을 줄였다. 또한 트래픽양의 변화에 따라 망 전체의 필요한 대역폭을 효과적으로 관리하고 변화시킴으로써 대역폭 사용의 효율성을 개선하였다. 그리고 우선순위 서비스를 제공할 수 있는 MPLS 망에서 우선순위에 따른 트래픽에 대해서도 전체 망에 도메인을 나눔으로써 우선순위가 높은 트래픽에 대한 종단간 복구방법에 대해 효율적인 자원 할당을 하며 낮은 우선순위의 트래픽에 대해서 장애가 발생한 도메인 내에서만 경로 복구를 하여 재설정을 위한 시간을 줄일 수 있고, 불필요한 메시지의 전달을 줄일 수 있다

  • 상호-코렌트로피 개념은 가우시안 커널의 커널 밀도 추정법에 의해 구축된 두 가지 서로 다른 확률밀도함수의 내적으로 표현될 수 있다. N개의 랜덤 심볼열과 상호-코렌트로피의 최대화 (MCC) 에 바탕을 두고 개발된 블라인드 알고리듬은 탁월한 학습 성능을 보인다. 그러나 이 알고리듬은 MCC 기반으로 가중치를 갱신할 목적으로 설계되면서 과도한 계산 복잡도를 지니게 된다. 이 논문에서는 상호-코렌트로피의 기울기 계산을 반복적으로 수행하여 MCC 알고리듬의 계산상의 복잡도를 크게 줄이는 방법을 제안하였다. 기존의 MCC 알고리듬은 블록 처리 방식에 의해 기울기를 계산하여 $O(N^2)$의 계산량이 필요했던 반면 제안된 방법은 O(N)의 계산만을 수행한다. 시뮬레이션 결과로부터, 제안된 이 방법이 기존의 알고리듬과 비교하여 계산량의 부담을 크게 줄이면서도 동일한 학습 성능을 보였다.

  • Background: Patients with breast cancer can experience a feeling of hopelessness very deeply in the adjustment process, and the social support provided during this period can be effective in increasing the level of hope. The present study aimed to identify breast cancer patients' social support and hopelessness level. Materials and Methods: The target population of this analytical study was all breast cancer patients (total of 85) who had treatment in the oncology department of a university hospital located in Adana/Turkey and who met the inclusion criteria. Data were collected through "Personal Information Form", "Beck Hopelessness Scale (BHS)" and "Multidimensional Scale of Perceived Social Support" (MSPSS). Analysis was performed using Shapiro Wilk, One Way ANOVA Welch, Student t-test, Mann Whitney U, and Kruskall Wallis tests. Homogeneity of variance was tested with the Levene, Bonferroni and Games Howell tests. Mean scores and standard deviation values are given as descriptive statistics. Results: Average age of the participants with breast cancer is $48.6{\pm}10.6$. Of all the participants, 84.7% are married, 49.4% graduated from primary school, 81.2% are housewives, and 82.4% had children. The participants' multidimensional perceived social support total scores were found to be high ($57.41{\pm}13.97$) and hopelessness scale scores low ($5.49{\pm}3.80$). There was a reverse, linear relationship between hopelessness scale scores and social support total scores (r=-0.259, p=0.017). A statistically significant relationship was found between hopelessness scores and education level and having children, occupation, income status, and education level of spouses (p<0.05). Conclusions: The present study indicates that hopelessness of the patients with breast cancer decreased with the increase in their social support. Therefore, activating patient social support systems is of importance in increasing their level of hope.

  • The region of Southeast Asia had already experienced rapid urbanization and cultural change before the East Asia region did. None the less, nowadays shophouses and rowhouses still form the major portion of streets in Chinese town in Southeast Asia countries. The purpose of this study is to examine the adaptation process of shophouse and rowhouse in the Southeast Asia region and the architectural characteristics between the middle of 18th and the early of 20th, which Chinese people of the region inherit and develop, for more thorough understanding of cultural adaptability and regionalism of Chinese architecture in Southeast Asia. The common fact found in the Southeast Asia region is that Chinese people in countries of this region gradually started to live densely as a group in a certain zone in city area since they got to play important roles in commerce, trade and service works related with cities, due to European countries' advance into Southeast Asia and their construction of colonial cities in the region. Chinese people in the region utilized residential rowhouse and special shophouse, which is a kind of shop adapted from rowhouses' sitting room or storage, for their commercial and industrial activities in urban areas, which had problems of limited space. They also realized high densities through vertical expansion of space in order to adjust to changing urban structure under execution of urban planning in cities of colonial area and rapid urbanization. Even though residence of Chinese in Southeast Asia was influenced by new political, social, economic and cultural rules of European colonies in Southeast Asia, it has continuously succeeded to the cultural tradition of China, their home country, in terms of planning principle which puts air well in the middle and hierarchial spacial construction method. Appearance of the open connected verandah, designed by Stamford Raffles, the founder of Singapore, can be regarded as one of the architectural characters. Hence, Chinese residence in cities of Southeast Asia can be understood as a new regional architectural culture in the context of European countries' urban planning and urbanization of colonial areas, Immigrants from southern China and their role, their adjustment to urban areas by utilizing mixed type houses of residence and business, cultural tradition of Chinese home country.

  • Medical dispute means the dispute between the hospital and the patient due to a medical accident. In general, medical accidents must be in accordance with the terms that are used in the medical dispute adjustment method stated in Article 2 (definition). In relation to this, there is a need to discuss an efficient operation scheme for Alternative Dispute Resolution (ADR) in medical disputes. In addition, it is necessary to look at issues of civil liability and criminal liability. In particular, in the consumer dispute arbitration committee, there is a case to make a "decision not to adjust" in aggressive intervention in the process of conflict resolution. The medical staff, on the basis of its "decision," can use this as a proven material for civil and criminal cases. This is rather upon the determination of the consumer council as a typical side effect to defend the user's perspective. This is the "decision" as was expressed from an order, "not adjusted." It is also determined to be easy and clearly timely. In the medical litigation, it is requesting the burden of proof of a patient's cause-and-effect relationship with the doctors committing negligence and medical malpractice. This seems to require the promotion of legislation in the direction to reduce future cases. It is determined that the burden of proof of medical accidents must be improved. The institution receiving the medical accident should prevent a closure report. Further, it is necessary to limit the transition to a franchise point. In this paper, we understand the problems of the current medical dispute resolution system, trying to establish a medical dispute resolution system desirable through an efficient alternative. In addition, it wants help in the protection and realization in medical consumers' and patients' rights. The relevant authorities will take advantage of these measures. After all, this could contribute to the system for a smooth resolution of a medical dispute.

  • Unnatural working postures usually cause musculoskeletal problems for workers in work field, especially in traditional industry. Many analysis and survey methodologies have been developed to identify unnatural postures and disorder risks in workplaces. The Ovako Working Posture Analyzing System (OWAS) and Nordic Musculoskeletal Questionnaire (NMQ) are the representative methods and applied widely. This study applied the both tools to investigate the work field of a manufacturing factory of the water heater's case. We divided the manufacturing process into nine workshops, took the pictures of working motions by DV camera and analyzed the postures on OWAS. From the OW AS results, we could identify the risks level of musculoskeletal symptoms as four Action Categories (AC). And from the comparison of OWAS and NMQ results, we could provide the suggestions to improve the working methods and environment. From the results of OWAS, we found that the operators' head/neck and back were above AC3 in some workshops. If the situation continued in long period, the operators might have the risk to get musculoskeletal symptoms. From the investigation of NMQ, we also found that the percentage of aches on neck, shoulders and lower back were higher than other parts of body. The correlation between aches and jobs was more than 75%. So we provided some suggestions to improve: work rotation and adjustment of work surface/height to fit in with Ergonomics. Then the risks of musculoskeletal symptoms would be reduced.
