1. This study aimed to explore the effect of recorded auditory prompts on helping an adult with profound mental retardation to take bath independently. 「A-B-C-A-C」design, a kind of single-subject experiment was adopted. Three phases, baseline phase, intervention phase(B): auditory prompt, and intervention phase(C): recorded auditory prompt were included. A female with profound mental retardation participated in the experiment. It took over seven months to finishing the intervention. The results of the experiment indicated that auditory prompts, whether human auditory prompt or recorded prompt, could help the client to take bath more independently. The families of the client also regarded recorded auditory prompt was a feasible solution. Based on the result, there were some suggestions for the further research. 본 연구의 목적은 녹음 구어 제시를 이용해서 극 중도 지능장애 성인 여성 스스로 목욕 동작을 완성 할 수 있도록 도와주는 효과에 대한 연구입니다. 본 연구에 사용하는 연구법은 ⌜A-B-A-C-A-C⌟역 설계이다. 기선기의(A)개입一(B)인공구어제시 개입二(C)녹음 구어 제시로 나누어졌다. 실험기간은 모두 7개월 반이었다. 연구결과는 피 실험자가 스스로 목욕할 때와 비교했을 때 인공구어 제시와 녹음구어 제시는 모두 피 실험자가 목욕 동작을 완성 하는 데에 효과가 있는 것으로 나타났다. 이 외에도 녹음 구어 제시는 피 실험자 가족들도 받아들일 수 있다. 본 연구 결과에 근거해서 연구자들은 미래 응용과 연구에 대한 건의도 제출하였다.

Aims: Insufficient data regarding the treatment strategy for partial response to nucleot(s)ide analogue (NUC) raised the aim of investigating tenofovir alafenamide (TAF) switching for chronic hepatitis B (CHB) patients with advanced fibrosis and partial response to other NUCs. Methods: CHB patients with advanced fibrosis (stage 3 or 4) and under NUC (except TAF) therapy with detectable hepatitis B virus (HBV) DNA for >52 weeks are enrolled to TAF 25 mg/day for 96 weeks. The objectives are viral suppression, alanine aminotransferase (ALT) normalization and safety. Results: From Feb. 2019, 34 patients, including 21 (61.8%) with entecavir, 10 (29.4%) TDF and 3 (8.8%) lamivudine or adefovir, were enrolled (15 [44.1%] male, median 53 years). The fibroscan demonstrated a mean of 10.5 kPa (7 [20.6%] cirrhotic). Sixteen (47.1%) patients were HBV e antigen positive, seven (20.6%) had YMDD mutation. The median HBV DNA level declined from 68.5 IU/mL at enrollment to 27.0 IU/mL at 4<sup>th</sup> week, and undetectable at 12<sup>th</sup>, 24<sup>th</sup>, 36<sup>th</sup> week, respectively, after TAF switching, with undetectable HBV DNA in 14/34 (41.2%), 17/33 (51.5%), 15/25 (60.0%), and 9/15 (60.0%) patients and rate of ALT normalization (≤40 U/L) of 85.3%, 85.3%, 84.8%, 92.0%, and 80.0%, respectively, after TAF switching. (figure 1) Two patients experienced transient virological breakthrough and another one developed at the final time follow up. Serum creatinine and eGFR levels were stable after TAF switching (figure 1). Two patients early terminated including one at 12<sup>th</sup> week due to personal reason, and another one accidently died at 20<sup>th</sup> week due to acute heart attack. Others suffered only mild degrees of adverse events which were considered unrelated to treatment. Conclusions: The preliminary results demonstrated the TAF switching is effective and safe in viral suppression for CHB patients with advanced fibrosis and partial virologic responses to other NUCs.
An Eye for an Eye: Signaling Before and During the Korean War of 1950.53
( Ming Chen Shai ),( Chien Wei Chen ) 한국국방연구원 2012 The Korean Journal of Defense Analysis Vol.24 No.2
Although signaling is the essence of diplomacy, it has often been overlooked in previous studies on international crises. In fact, whether states in a dyad escalate disputes to the brink of war or seek conflict resolution, both sides of a crisis use these forms of signaling to convey their intended messages and possible responses. However, in most of these dyadic international conflicts, the patterns of signaling motives are not identified. In this article, it is argued that signaling decisions depend on the interaction of contextual dimensions, perceived threats, and the status disparity facing the states in a dyad. By analyzing both the signaling and the counter-signaling of nations in dyadic interactions, an alternative insight is offered into why the Korean War turned out to be inevitable.
Optimal Lot-sizing and Pricing with Markdown for a Newsvendor Problem
Chen, Jen-Ming,Chen, Yi-Shen,Chien, Mei-Chen Korean Institute of Industrial Engineers 2008 Industrial Engineeering & Management Systems Vol.7 No.3
This paper deals with the joint decisions on pricing and ordering for a monopolistic retailer who sells perishable goods with a fixed lifetime or demand period. The newsvendor-typed problem is formulated as a two-period inventory system where the first period represents the inventory of fresh or new-arrival items and the second period represents the inventory of items that are older but still usable. Demand may be for either fresh items or for somewhat older items that exhibit physical decay or deterioration. The retailer is allowed to adjust the selling price of the deteriorated items in the second period, which stimulates demand and reduces excess season-end or stale inventory. This paper develops a stochastic dynamic programming model that solves the problem of preseason decisions on ordering-pricing and a within-season decision on markdown pricing. We also develop a fixed-price model as a benchmark against the dual-price dynamic model. To illustrate the effect of the dual-price policy on expected profit, we conduct a comparative study between the two models. Extension to a generalized multi-period model is also discussed.

Purpose: Cancer cells develop acquired resistance induced by chemotherapeutic drugs. In this study, we investigated the effects of brief treatment with cytotoxic drugs on the phenotype of breast cancer cells. Methods: Breast cancer cells MCF7 and BT-474 were briefly treated with paclitaxel or doxorubicin. Clonogenic, migration, and invasion assays were performed on the treated cells. Western blot analysis and RhoA activity assay were also performed. Results: Breast cancer cells when briefly treated with paclitaxel or doxorubicin showed reduced clonogenic ability. Doxorubicin, but not paclitaxel, augmented cell migration and invasion. The invasion-promoting effects of doxorubicin were lost when the two drugs were sequentially used in combination. Myosin light chain (MLC) 2 phosphorylation and RhoA activity were upregulated by doxorubicin and downregulated by paclitaxel. Pretreatment with RhoA inhibitors abolished the migration- and invasion-promoting effects of doxorubicin. Conclusion: Doxorubicin activates the RhoA/MLC pathway and enhances breast cancer cell migration and invasion. Therefore, this pathway might be explored as a therapeutic target to suppress anthracycline-enhanced tumor progression.
On eBay's Fee Structure from a Channel Coordination Perspective
Chen, Jen-Ming,Cheng, Hung-Liang,Chien, Mei-Chen Korean Institute of Industrial Engineers 2010 Industrial Engineeering & Management Systems Vol.9 No.2
Can eBay.com's fee structure coordinate the channel? It's a critical strategic problem in e-commerce operations and an interesting research hypothesis as well. eBay's fees include three parts: monthly subscription fee, insertion fee, and final value fee (i.e., a revenue sharing portion), which represent a generic form of revenue sharing fee structure between the retailer and the vendor in a supply chain. This research deals with such a channel consisting of a price-setting vendor who sells products through eBay's marketplace exclusively to the end customers. The up- and down-stream channel relationship is consignment-based revenue sharing. We use a game-theoretic approach with assumption of the retailer (i.e., eBay.com) being a Stackelberg-leader and the vendor being a follower. The Stackelberg-leader decides on the terms of revenue sharing contract (i.e., fee structure), and the follower (vendor) decides on how many units to sell and the items' selling price. This study formulates several profit-maximization models by considering the effects of the retail price on the demand function. Under such settings, we show that eBay's fee structure can improve the channel efficiency; yet it cannot coordinate the channel optimally.
