The purposes of this study is to identify the perception of students' use of university libraries' public relations activities using Instagram and propose ways to improve the operation of university libraries' Instagram. To this end, the status of Instagram operations of domestic and foreign university libraries was investigated, and a survey was conducted on 292 students who used the library Instagram of their universities. Based on the research results, first, it is necessary to promote the use of libraries by using 'Library Events' information closely related to the use of Instagram by students, but planning ways to participate that can lead to practical use of libraries. Second, it is necessary to promote the role of librarians through Instagram and utilize daily communication information in order to positively affect library image recognition. Third, it is necessary to guide users on how to inquire on library Instagram and actively respond to communication with users through periodic post uploads and monitoring.

In this paper I discuss a more complicated case of 'It'-Extraposition in English in the Optimality Theory [1] by further modifying and extending the analysis done in Khym (2018) [2] in which only the 'relatively' simple cases of 'It'-Extraposition such as 'CP-Predicate' was dealt with. I show in this paper that the constraints and the constraint hierarchy developed to explain the 'relatively' simple cases of 'It'-Extraposition are no longer valid for the more complicated cases of 'It'-Extraposition in configuration of 'CP-V-CP'. In doing so, I also discuss two important theoretic possibilities and suggest a new view to look at the 'It'-Extraposition: first, the long-bothering question of which syntactic approach between P&P (Chomsky 1985) [3] and MP (Chomsky 1992) [4] should be based on in projecting the full surface forms of candidates may boil down to just a simple issue of an intrinsic property of the Gen(erator). Second, the so-called 'It'- Extraposition phenomenon may not actually be a derived construction by the optional application of Extraposition operation. Rather, it could be just a representational construction produced by the simple application of 'It'-insertion after the structure projection with 'that-clause' at the post-verbal position. This observation may lead to elimination of one of the promising candidates of '$It_i{\ldots}[_{CP}that{\sim}]_i$' out of the computation table in Khym [2], and eventually to excluding the long-named 'It'-Extraposition case from Extrsposition phenomena itself. The final constraints and the constraint hierarchy that are explored are as follows: ${\bullet}$ Constraints: $^*SSF$, AHSubj, Subj., Min-D ${\bullet}$ Constraint Hierarchy: SSF<<>>Subj.>> AHSubj.

Background: Scarce data have been reported on the efficacy of concomitant atrial fibrillation (AF) ablation in patients undergoing bioprosthetic valve replacement. Methods: From 2001 and 2014, 146 consecutive patients ($69.3{\pm}9.4years$, 84 females) who underwent bioprosthetic heart valve replacement concomitant with AF ablation were assessed. We evaluated long-term rhythm and valve-related outcomes. Results: During 49.1 months of follow-up (interquartile range, 22.5-96.8 months), 7 in-hospital and 49 (6.7% per person-year) post-discharge deaths occurred. The thromboembolic event-free survival rate at 5 years was $79.2%{\pm}3.5%$. The freedom from AF recurrence rate at 5 years was $59.8%{\pm}4.9%$. Multivariate analysis showed that old age (hazard ratio [HR], 1.06; 95% confidence interval [CI], 1.02-1.11; p=0.002), previous cardiac operation (HR, 3.01; 95% CI, 1.22-7.43; p=0.02), and a large left atrial (LA) dimension (HR, 1.02; 95% CI, 1.00-1.05; p=0.045) were significantly associated with AF recurrence. Conclusion: The overall long-term clinical outcomes in these predominantly elderly patients undergoing AF ablation concomitantly with bioprosthetic valve replacement were satisfactory; however, AF recurrence was frequent. Older age, a history of prior cardiac surgery, and large LA size were associated with an increased risk of AF recurrence.

Objective : Hydatid cyst disease is caused by the parasite Echinococcus granulosus. It is rarely seen in the vertebral system, occurring at a rate of 0.2-1%. The aim of this study is to present 12 spinal hydatid cyst cases, and propose a new type of drainage of the cyst. Methods : Twelve cases of spinal hydatid cysts, surgical operations, multiple operations, chronic recurrences, and spinal hydatic cyst excision methods are discussed in the context of the literature. Patients are operated between 2005 and 2016. All the patients are kept under routine follow up. Patient demographic data and clinicopathologic characteristics are examined. Results : Six male and six female patients with a median age of 38.6 at the time of surgery were included in the study. Spinal cyst hydatid infection sites were one odontoid, one cervical, five thoracic, two lumbar, and three sacral. In all cases, surgery was performed, with the aim of total excision of the cyst, decompression of the spinal cord, and if necessary, stabilization of the spinal column. Mean follow up was 61.3 months (10-156). All the patients were prescribed Albendazole. Three patients had secondary hydatid cyst infection (one lung and two hepatic). Conclusion : The two-way drainage catheter placed inside a cyst provides post-operative chlorhexidine washing inside the cavity. Although a spinal hydatid cyst is a benign pathology and seen rarely, it is extremely difficult to achieve a real cure for patients with this disease. Treatment modalities should be aggressive and include total excision of cyst without rupture, decompression of spinal cord, flushing of the area with scolicidal drugs, and ensuring spinal stabilization. After the operation the patients should be kept under routine follow up. Radiological and clinical examinations are useful in spotting a recurrence.

In recently, a climatic change(such as subtropical climate and frequent unusual high temperature) and the open-trade policies of agricultural & livestock products are increasing the outbreak risk of highly pathogenic avian influenza(HPAI) and foot and mouth disease(FMD), and accordingly the socio-economic damage and impacts are also increasing due to the cases such as damage from the last 5 times of FMD outbreak(3,800 billion won), from 10 years public control cost of Pine Wilt Disease (PWD)(238.3 billion won), and from the increased invasive pests of exotic plant like isoptera. Therefore, the establishment of new operation strategy of IoT(Internet of Things) based satellite early warning system(SEWS) for plants and animals as a subsystem of national disaster response and management system is being required, where the forensic technology & measures should be applied as a government policy to estimate the post compensation and to carry out the legal responsibility.

[Purpose] It aims to suggest the differential factors to enhance the customer satisfaction and to activate the shopping in the convenience store (CVS). [Methodology] Convenience store service convenience (CVS SERVCON) was developed at the first time and the gap of relative importance level between the owners and the consumers was assessed by AHP analysis method..[Findings] First, the importance of access convenience was assessed as the first priority in both CVS owners' group and the consumers' group, while the detailed elements showed the differences which required the improvements. Based on the consumers' assessment, the importance of location was relatively low. They assessed relatively high on 24 hours operation of CVS and personal services. Second with respect to the transaction convenience, CVS owners' group rated it as the fourth priority while the consumers' group rated as the second, which requires the improvement. Third in terms of benefit utility and value-added service of post-benefit convenience which are the sub-factors of benefit convenience, the rate on the importance from the consumers showed higher than that from the owners, which requires the improvement. [Implications] Based on this study results, CVS operating companies are anticipated to be able to satisfy the customers, moreover, to secure the loyal customers if they concentrate the resources to develop the differentiation strategy on the areas where the consumers' demands are high while performs the maintenance strategy on the areas where their demands are low. In addition, this study contributed the theoretical expansion of SERVCON upon development of CVS SERVCON to comply with its definition.

Objective: To evaluate the effectiveness of the pulmonary recruitment maneuver (PRM) at the end of the operation to decrease laparoscopy-induced abdominal or shoulder pain after gynecological oncologic surgery. Methods: In total, 113 women undergoing laparoscopic surgery for malignant or premalignant gynecological lesions were assigned randomly to two groups: the PRM group (the patient was placed in the Trendelenburg position ($30^{\circ}$) and the PRM, consisting of two manual pulmonary inflations to a maximum pressure of $40cmH_2O$) (n=54) and the control group (n=52). Postoperative shoulder and abdominal pain was assessed 12, 24, and 48 hours later using a visual analog scale (0-10). In addition, the incidence of post-discharge nausea and vomiting was recorded until 48 hours after discharge. Results: Postoperative shoulder pain at 12 and 24 hours was significantly less severe in the PRM group ($2.2{\pm}0.5$ and $2.0{\pm}0.4$) than in the control group ($4.0{\pm}0.5$ and $3.9{\pm}0.4$; both p<0.001). The PRM significantly reduced the severity of upper abdominal pain at 12 and 24 h compared with the control group ($3.1{\pm}0.4$ and $2.9{\pm}0.4$ vs. $2.9{\pm}0.5$ and $4.9{\pm}0.5$; both p<0.001). The analgesic requirement during the postoperative period was similar in the two groups (control group, 78.8%; PRM group, 75.9%; p=0.719). Conclusion: The PRM effectively and safely reduced postoperative shoulder and upper abdominal pain levels in patients undergoing laparoscopic gynecological oncologic surgery.

Purpose - This paper aims to investigate the mediating effects of relationship fairness factors between franchisor's support services and performance(re-contract intention) in food service franchise. More specifically, fairness was measured into distributive, procedure, interaction, and information, franchisor's support service was divided into pre-start support services (initial support services) and post-start support services (continued support services), and performance (re-contract intent) was measured using 3 items such as re-contract, contract extension, and recommendation. Research design, data, and methodology - The population for the survey is the head of franchises in the metropolitan area (Seoul/Gyeonggi), which operates a restaurant franchise, and samples included a wide range of overseas/domestic brands and regions. The survey was conducted from August 1 to September 30, 2018 through the survey agency. The survey was conducted together with a telephone interview and a direct visit by the investigator. A total of 205 questionnaires were collected and retrieved, 4 questionaires containing missing information were excluded and 201 responses were used for analysis. Results - The results shows that franchisor's initial support services have significant positive effects on procedural, interpersonal, and informational relationship fairness, and continuous support services have significant positive effects on distributive, procedural, interpersonal, and informational relationship fairness. This study also shows that informational and procedural fairness have significant positive effects on performance(re-contract intention). Finally, continuous services a significant positive effect on performance(re-contract intention). Conclusions - The results show that franchisor make a manual, and should improve fairness through regular investigation whether support services was executed as promised in the manual after franchisee operation. In addition, information fairness and procedural fairness have been shown to increase performance(re-contract intention). These results mean that the franchisor's headquarters should provide product and service support for the merchant in accordance with the manual and management policy to reduce asymmetry in information and improve procedural fairness to enhance performance(re-contract intention).

Background: The purpose of this study is to identify the elements for the construction of the Korean academy of orthopedic manipulative physical therapy's (KAOMPT's) non-face-to-face lecture system using the Delphi method. Methods: The Delphi method was applied to 50 expert panel members of the Central Committee and the Provincial Branch of the KAOMPT. The Delphi survey was conducted in two rounds, and the first Delphi survey collected opinions on 40 questions on 12 topics. The second Delphi survey was collected into 25 questions on 4 topics. As a result of the survey, the content validity ratio (CVR), consensus and convergence were measured. Referring to the number of expert panels and previous studies were determine a CVR of at least 2.29, a consensus of at least .75 and a convergence of 0 to .5. Result: In the first Delphi result, out of the total 40 items, 20 items with high content validity ratio were found, and 10 items found double agreement. In the second Delphi result, 13 out of the total 25 items had a content validity ratio higher than 2.29, and 5 items found a double agreement. Conclusion: This study derived items on the role of central and municipal councils, lecture support and lecture room construction, non-face regular course and special lecture operation and personnel for the establishment of non-face-to-face lecture system. Based on this content, it is expected that it will help establish a non-face-to-face lecture system in 2021 through a pilot non-face-to-face lecture that will be implemented in the future.

There are a number of voice analysis programs around the world. Domestic voice analysis is performed by relying heavily on specific commercial program. We intend to develop coding for voice analysis using Praat and apply it to clinical practice. This study consisted of Experiment 1 and Experiment 2. Experiment 1 was the development of automated voice analysis coding based on Praat. The coding was largely divided into a recording, an analysis, and a storage section. Experiment 2 was applied to the voice analysis of 2 male patients pre- and post-operation with this coding. The analysis parameters of this coding provided 26 parameters for vowel /a/, nine parameters for sentence analysis, and a total of 4 parameters for voice range profile analysis. In two male patients, the pitch and the intensity increased, the voice quality improved, and the sentence length decreased after surgery. The coding was well made, so the output was good in real time. The code is automated as much as possible to block manual errors and increases convenience and efficiency by generating the result sheet in real time.
