Background: The standard treatment in the metastatic colorectal cancer consists of 5-FU based infusional regimens. However, with oral fluoropyrimidines, equal tumor responses may be obtained. Capecitabine causes macrocytosis of the cells by inhibition of DNA synthesis. In this context, a relationship was found between mean corpuscular volume (MCV) and response to therapy in breast cancer patients treated with Capecitabine, but whether this relationship also pertains in colorectal cancer has not been established. Materials and Methods: A total of 102 metastatic colorectal cancer patients treated with a oxaliplatin (XELOX)${\pm}$Bevacizumab combination were retrospectively evaluated. Patients were randomized into three groups. Hematological parameters (MCV, MPV, PCT, PLT, NLR) were recorded retrospectively, before treatment and after 3 cycles of chemotherapy. Results: After three cycles of therapy, 20 (19.6%) patients had progressive disease (PD), 41 (40.1%) had stable disease (SD), and 41 (40.1%) demonstrated a partial response (PR). In 62 (60.7%) treatment was with capesitabin plus XELOX therapy, and in 40 (39.2%) it was XELOX-Bevacizumab combination therapy. There was no difference among three groups before the treatment in terms of MCV, MPV, PCT, PLT, and NLR. MCV showed significant increase in chemotherapy response groups (PR and SD). In addition, a significant decrease was observed for platelet count in chemotherapy response groups. While NLR decrease was seen in only a PR group, PCT decrease was observed in all three groups. PCT and PLT values were higher in patients receiving Bevacizumab. Conclusions: PLT, PCT, MPV, and NLR values were decreased due to Capecitabine-based chemotherapy, however MCV was increased. PCT and PLT values were higher in patients who received Bevacizumab than those who did not. MCV, PLT, and NLR can be considered as important factors in predicting response to colorectal carcinoma treatment.

Purpose: To evaluate the usefulness of positron emission tomography/computed tomography (PET/CT) for field modification during radiotherapy in esophageal cancer. Materials and Methods: We conducted a retrospective study on 33 patients that underwent chemoradiotherapy (CRT). Pathologic findings were squamous cell carcinoma in 32 patients and adenocarcinoma in 1 patient. All patients underwent PET/CT scans before and during CRT (after receiving 40 Gy and before a 20 Gy boost dose). Response evaluation was determined by PET/CT using metabolic tumor volume (MTV), total glycolytic activity (TGA), MTV ratio (rMTV) and TGA ratio (rTGA), or determined by CT. rMTV and rTGA were reduction ratio of MTV and TGA between before and during CRT, respectively. Results: Significant decreases in MTV ($MTV_{2.5}$: mean 70.09%, p < 0.001) and TGA ($TGAV_{2.5}$: mean 79.08%, p < 0.001) were found between before and during CRT. Median $rMTV_{2.5}$ was 0.299 (range, 0 to 0.98) and median $rTGAV_{2.5}$ was 0.209 (range, 0 to 0.92). During CRT, PET/CT detected newly developed distant metastasis in 1 patient, and this resulted in a treatment strategy change. At a median 4 months (range, 0 to 12 months) after completion of CRT, 8 patients (24.2%) achieved clinically complete response, 11 (33.3%) partial response, 5 (15.2%) stable disease, and 9 (27.3%) disease progression. $SUV_{max}$ (p = 0.029), $rMTV_{50%}$ (p = 0.016), $rMTV_{75%}$ (p = 0.023) on intra-treatment PET were found to correlate with complete clinical response. Conclusion: PET/CT during CRT can provide additional information useful for radiotherapy planning and offer the potential for tumor response evaluation during CRT. $rMTV_{50%}$ during CRT was found to be a useful predictor of clinical response.

Objective: This work aimed to evaluate the safety and clinical efficacy of transcatheter arterial chemoembolization (TACE) combined with c-arm cone-beam CT guided synchronous radiofrequency ablation (RFA) in treatment of large hepatocellular carcinoma (HCC). Methods: 21 patients with large HCC were studied from January 2010 to March 2012. TACE combined with synchronous C-arm cone-beam CT guided RFA were performed on a total of 25 lesions. Conventional imaging examination (CEUS, enhanced CT or MRI) and AFP detection were regularly conducted to evaluate the technical success rate of combined treatment, complications, treatment response, time without disease recurrence and survival rate. Results: The technical success rate of combined treatment was 100%, without any significant complication. After 1 month, there were 19 cases with complete response and 2 cases with partial response, with an complete response rate of 90.4% (19/21) and a clinical effective rate of 100% (21/21). The complete response rates of single nodular lesions (100%, 17/17) was significantly higher than that of multiple nodular lesions (50%, 2/4) (P<0. 05). During 2 to 28 months of follow-up, in 19 cases with complete response, the average time without disease recurrence was $10.8{\pm}6$ months. The total survival rates of 6, 12 and 18 months in 21 patients were 100%, respectively. Conclusion: TACE combined with synchronous C-arm CT guided RFA is safe and effective for treatment of large HCC. The treatment efficacy for single nodular lesion is better than that for multiple nodular lesions.

Purpose: The purpose of this study was to identify Compassion Fatigue (CF), Somatization, and Silencing Response (SR) among nurses and understand intermediate effects between the variables. Methods: The sample of 240 nurses who were working three shifts in medical and surgical wards, and emergency room were recruited in three hospitals with over 700 beds. A structured questionnaire was used which included CF, Somatization and SR scales. The data were analyzed using descriptive statistics, ANOVA, Pearson's correlation coefficients and stepwise multiple regression. Results: There were statistically significant differences in CF, Somatization and SR depending on perceived personal health condition, experience of turnover, co-worker support. There were significant correlations between those study variables. The result also indicated that burnout (${\beta}$=.81, p<.001) which is a part of Secondary Traumatic Stress and Somatization (${\beta}$=.79, p<.001) have the role of partial mediator in the relationship between Secondary Traumatic Stress and Silencing response. Conclusion: The results of study show that an intermediary role by Burnout and Somatization in Silencing response of nurses is important for effective human resource management in hospital nursing staffs. Effective human resource management which includes mentoring and social support system can enhance the professional quality of life of nurses, which will eventually contribute to the quality of care by those care providers and counselors.

Central Cancer Registry of Korean National Cancer Center in 1999 reported that mortality from lung cancer is higher than mortality from stomach cancer or hepatocellular carcinoma in Korean male. Lung cancer is classified into small cell cancer and non-small cell lung cancer (NSCLC), and NSCLC patients account for $70\%$ of the whole lung cancer patients. The purpose of this study was to evaluate the efficacy and toxicity of docetaxel and cisplatin combination in Korean patients with NSCLC. All patients who had received the combination therapy of docetaxel and cisplatin for histologically confirmed NSCLC in Ajou University Hospital between 2000. $2\~2001$. 4 were retrospectively evaluated for the responses and toxicities of that combination therapy. Nineteen patients were treated with docetaxel 75 $mg/m^2$ on Day 1 and cisplatin 25 $mg/m^2$ on Day 1-3 every 4 weeks. The response for combination regimen was evaluated by CT scans after 2 or 3 cycles of treatments. Seventeen patients were evaluated for the responses and the 19 patients far the toxicities. Among the 19 patients (14 men and 5 women), there were one patient $(5.3\%)$ with stage I disease, 4 patients $(21.1\%)$ with stage III disease, and 14 patients $(73.1\%)$ with stage IV disease. Of the 17 patients who were evaluable for response, complete response (CR) was not observed in any patient while partial response (PR) was observed in 5 patients $(29.4\%)$. The overall response rate (CR+PR) was $29.4\%$. Stable disease (SD) was observed in 11 patients $(64.7\%)$ and progressive disease (PD) in 1 patient $(5.9\%)$. The toxicities were graded by NCI (National Cancer Institute) Common Toxicity Criteria for the evaluable 70 cycles. Grade 3 or 4 neutropenia occurred in 53 cycles $(76\%)$. Four patients were hospitalized due to febrile neutropenia. The combination chemotherapy of docetaxel and cisplatin was effective as NSCLC treatments, however, the regimen must be administered carefully due to its hematological side effects.

Lightly reinforced concrete (RC) moment frames may suffer significant damage during large earthquake events. Most buildings with RC moment frames were designed without considering seismic loads. The load-displacement response of gravity load designed frames could be altered by masonry infill walls. The objective of this study is to investigate the load-displacement response of gravity load designed frames with masonry infill walls. For this purpose, three-story gravity load designed frames with masonry infill walls were considered. The masonry infilled RC frames demonstrated larger lateral strength and stiffness than bare RC frames, whereas their drift capacity was less than that of bare frames. A specimen with a partial-height infill wall showed the least drift capacity and energy dissipation capacity. This specimen failed in shear, whereas other specimens experienced a relatively ductile failure mode (flexure-shear failure).

Businesses are using culture marketing as a new promotional tool and as a marketing strategy since consumers have desire for not only economical fulfilment, but also emotional and psychological fulfilment. Similar to service industry, medical service industry has started to use culture marketing on its service industry management side. Therefore, this paper will propose necessity and usable culture marketing in hospitals to identify the current position of culture marketing in medical service industry. In conclusion, the present research offers the following implication. First, culture marketing has a partial offsetting impact to those who have negative emotion regarding the medical service industry. This is because of the positive impact of culture marketing on a customer response and customer satisfaction. Moreover, by considering the fact that only a culture synthesis and a culture style have a positive impact, focusing on a culture synthesis and a culture style would be treated as an advantageous strategy.

Turnaround time of a job performing frequent disk I/O operations is greatly affected by I/O bottleneck which incurs due to the large gap in the speeds of I/O devices and the CPU. This paper proposes to employ a Write Dedicated Buffer(WDB) in disk arrays to improve the response time for read requests and analyzes the scheduling policies and the efficiency of the WDB. Through a series of simulations we show that, among the three policies examined, the partial stripe join(PSJ) policy is the most effective in terms of response time for both read and write requests and that, especially when using a WDB on declustered arrays, improvement of response time for read requests becomes greater as the request rate increases.

Currently, different kinds of diagnosis and inspection technologies are applied to prevent the internal mechanical transformation of transformers. For example, examination of internal Partial Discharge of transformer, analysis of transformer oil gas, and measurement Frequency Response Analyzer(FRA) are used to diagnose defect. Especially, diagnosis technique through Frequency Response Analyzer(FRA) has been used and developed from 1960, when it was first introduced, till now to become an important tool to examine presence of defect and to prove quality of machines for the most electric machine producers electric power company in the world. However, diagnosis through FRA is still in introduction level in Korea and the application method for FRA is not established yet. For that reason, study about the application of domestic electric installation according to the FRA is needed. It is expected that the study play an important part in the prevention of defect due to the internal transformation of transformer by introducing measurement theory, providing measurement method, and analyzing application cases.

Even the pharmacotherapy is more effective than placebo for the treatment of depression, the outcome of pharmacoltherapy remains unsatisfactory for many patients. Apart from side effects, there are two major limitations of antidepressant therapy. One is the delayed onset of improvement and another is partial response. In order to address these clinical dilemmas, many psychiatrists more commonly employ add-on therapy. In past, the practice of using multiple drugs to enhance treatment response was called polypharamcy, and was disparaged as poor clinical practice. However, with improved understanding of how drugs affects the central nervous system and increased communication in journals and on computer networks about the relative merits of specific combinations, the scientific basis for the combining drugs is being defined. Indeed, the use of multiple medications as a stratege to enhance response has become both acceptable and widespread now a days. It is now referred to more positively as add-on therapy, co-medication, combination therapy, or drug augmentation. Thus, as the methods of practical strategies for treatment of depression, switching classes antidepressant drugs, combination therapy, augmentation strategies and brief treatment algorithm will be presented with items of considerations. However, when combination of drugs being tried, knowledges about the action of mechanism, pharamcokinetics, and pharmacodynamics are essential to cope with the possible adversive reactions and to get the appropriate responses for the treatment of depressive symptoms.
