This study conducted a case study and a questionnaire analysis in parallel. In the case study, a study was conducted on domestic manufacturer A by analyzing pallet loading efficiency of RRP(Retail Ready Packaging) products and pallet loading efficiency of MWC(Membership Wholesale Club) delivered products. As a result of the pallet loading efficiency simulation of 50 RRP products of Manufacturer A, it was 80.0% based on the T-11 type pallet and 84.3% based on the T-12 type pallet. It was found It refers that the route of producing the product from the manufacturer A and delivering it to the MWC A in the form of RRP resulted in the decrease of the pallet loading efficiency through the change of the loading pattern and the adjustment of the number of loads. As a result of analyzing the questionnaire about whether the overall efficiency of the supply chain will be improved if the operation of the packaging system considering the SCM(Supply Chain Management) aspect is χ² = 178.500, there was a statistically significant difference at the significance level of 0.000. Manufacturers and logistics companies answered "yes" the most, but distributors answered "is average" the most, confirming that the packaging can be constructed with the highest operational efficiency. Therefore, as a result of confirming the impact of packaging design considering the SCM aspect on logistics efficiency, it indicates the importance of closer collaboration between manufacturers and distributors.

Background and Objectives: Recurrent respiratory papillomatosis (RRP) is difficult to treat because of its tendency to recur and spread throughout the aerodigestive tract. We aimed to estimate the effect of intralesional injections of cidofovir in patients with RRP. Materials and Method: Within the period from January 2003 to July 2007, 13 patients aged 2 to 61 years were treated with intralesional injections of cidofovir combined with surgical excision of RRP. Cidofovir was injected intralesionaly at a concentration of 5 mg/cc after complete removal of the papilloma with $CO_2$ laser or microdebrider. We evaluated the effect of intralesional cidofovir therapy by comparing pre-treatment mean interval of recurrence with post-treatment interval of recurrence. Results: Of 13 patients, two patients showed complete response during follow up period and four patients showed partial response. Seven patients did not respond to cidofovir at all. Mean pre-treatment mean interval of recurrence was 9 months and mean post-treatment interval of recurrence was 13.1 months (p=0.039). There was a statistical significance between the injected dose of cidofovir and post-treatment interval of recurrence (p=0.009). There were no local or systemic side effects caused by cidofovir. Conculsion : Intralesional injection of cidofovir seems to have a potential of a safe and effective adjuvant therapy of RRP. There was a positive correlation between the injected dose of cidofovir and patient clinical outcomes so that administration of higher doses and more frequency of injections should be needed to reduce recurrence. Further study regarding injection therapy regimen for RRP is required.

Recurrent respiratory papillomatosis (RRP) is characterized by repeated recurrence in the respiratory system, such as the pharynx, larynx, and trachea, caused by the human papilloma virus. The main treatment is surgical removal of the papilloma. However repeated recurrence of RRP in multiple areas is burdened for the surgeon. In addition to the surgery, various adjuvant therapies have been studied to reduce the recurrence. Literature review was conducted with a focus on the adjuvant treatments for RRP.

This study was carried out to investigate the quality characteristics and antioxidant activities of Rehmanniae radix (Rehmannia glutinosa Libosch. var. purpurea Makino) freeze-dried powder (RRP) and Rehmanniae radix preparata powder (RRPP). Under the Hunter color system, redness was higher and lightness/yellowness lower in RRPP, compared to RRP. The reducing sugar contents of RRP and RRPP were 0.8% and 6.0%, respectively (p<0.05). The pH was lower in the RRPP (RRP: 6.71, RRPP: 4.23). The amount of catalpol amount in RRPP (47.20 mg/mL) was lower than RRP (144.90 mg/mL). RRPP contained high amounts of 5-HMF (5-hydroxymethyl-2-furaldehyde, 47,231 mg/mL), but 5-HMF was not detected in RRP. Total phenol contents of RRP and RRPP were 2.10 mg/mL and 3.66 mg/mL, respectively. FRAP values of RRP and RRPP were 0.51 mg/mL and 1.99 mg/mL, respectively. The antioxidant activities by DPPH (1,1-diphenyl-2-picryl hydrazyl) and hydroxyl radical scavenging activity of RRPP were much higher than RRP. Based on these results, RRPP is a good candidate for food processing in terms for its physicochemical and antioxidative activities.

The objective of this study is to evaluate antioxidant activities of Rehmanniae Radix Preparata (RRP) prepared from dried root through nine repeated steaming-drying cycles. The total phenolic content of the final cycle of RRP increased to 165.2% compared with that of the 1st cycling product. Antioxidant activities which were determined by ferric-reducing antioxidant potential (FRAP), 2,2'-azinobis(3 ethybenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging, 1,1-diphenyl-2-picrydrazyl (DPPH), and hydroxyl radical scavenging activities, increased remarkably as the number of steaming-drying cycles increased. Especially, FRAP value increased to 89.1%. Further, $IC_{50}$ values for DPPH and hydroxyl radical scavenging activities of the final 9th-cycling product decreased to 58.3% and 67%, respectively. Based on these results, it was observed that the antioxidant activities of RRP improve according to an increased number of steaming-drying cycles.

In this study, the relationship between packaging design and logistics efficiency raised in prior research was to be conducted through empirical analysis in terms of SCM efficiency. The main research contents were carried out in the pursuit of efficiency of the relevant store operation, relationship with SCM efficiency aspects, resolution of differences in recognition between manufacturers and distributors, establishment of automated systems for RRP production facilities and processes in the manufacturer's facilities, logistics costs, environment and quality safety, and promotion of RRP through the manufacturer's packaging system. As a result of the verification of SCM efficiency aspects through this study, logistics efficiency will be reduced in the case of the packaging system or delivery system, where only the operational efficiency of the store is the top priority(χ² = 178.500, p < 0.001). This is because of the strong interaction between packaging and supply chain activities, many packaging systems affect the performance criteria of the supply chain, and the content that packaging personnel should ensure that the packaging system meets other essential requirements while meeting the primary goal of protecting the product is also a result consistent with the preceding study. An analysis of whether the RRP promotion through the manufacturer's packaging system would result in improved loading efficiency showed that there was a statistically meaningful difference at a significant level of 0.000, as χ² = 140.133.

The purpose of the present study was to investigate the effectiveness of reciprocal teaching procedure for improving Korean college students' reading comprehension of English text. In particular, this study sought to explore the qualitative features, if any, in students' use of reading comprehension strategies presented in the process of Reciprocal Reading Procedure (RRP). In order to accomplish the goal of the study, transcripts of the students' dialogues, open-ended questionnaires, and researchers' observation notes were examined. The results of the study showed that the participants used different four kinds of reading strategies in the process of RRP (questioning, clarifying, predicting, summarizing). The findings also suggested that the readers with limited knowledge of vocabulary had difficulty in moving on to the next level. Additionally, future research direction and some pedagogical implications are presented for the practical EFL classroom.

This study sought efficiency of collaboration between manufacturers and distributors by finding a way to improve logistics efficiency in order to save distribution cost and standardize packaging together with profit generation by way of simple-display packaging in discount stores. For the study purpose, the impact of products with RRP (Retail Ready Packaging) by each discount store on the collaboration achievement such as loading efficiency was observed. From this observation, an alternative packaging system that can improve logistics efficiency between manufacturers and distributors was sought and the role of distributors in distribution standardization was explored. The purpose of this study also includes suggesting some implications on future basic direction of environment-friendly management. If this study would induce distributors to have more interest in distribution standardization and if logistics efficiency would be enhanced by the operation of packaging system considered of compatibility with pallets, this study would have academic significance and create practical values.

Background: This study was performed to investigate the association between cystographic anastomotic urinary leakage (UL) after retropubic radical prostatectomy (RRP) and early urinary incontinence (UI). Methods: The medical records of 53 patients who had undergone cystography after RRP at our institution between January 2015 and December 2018 were retrospectively analyzed. Cystography was performed 7 to 10 days after surgery. The duration of catheterization depended on the degree of UL, which was classified as mild, moderate, or severe. The study subjects were divided into the non-UL group and the UL group. Continence was defined as the use of no pads. The prostate was dissected in an antegrade fashion, and urethrovesical anastomosis was performed with a continuous suture. Results: Incontinence rates at 1 and 3 months postoperatively were significantly higher in the UL group than the non-UL group (83.3% vs. 52.2%, p=0.014 and 76.7% vs. 47.8%, p=0.030, respectively); however, those at 6 and 12 months were not significantly different (23.3% vs. 17.4%, p=0.597 and 4.3% vs. 10.0%, p=0.440, respectively). The severity of UL was not found to influence the duration of incontinence. The presence of cystographic anastomotic UL was found to be predictive of UI during the first 3 postoperative months (odds ratio, 3.3; p=0.045). Conclusion: The presence of anastomotic UL on cystography was associated with higher rates of UI in the early postoperative periods. However, incontinence rates in patients with or without anastomotic UL immediately after RRP equalized at 6 months and the severity of UL did not affect the duration of postoperative UI.
