This study investigated the differences of perceived parenting attitude and academic stress on smartphone addiction according to the classification of addiction-risk group among middle school students. A descriptive research design was used. The subjects were 358 middle school students from five middle school in Daegu. Data were analyzed by descriptive statistics, ${\chi}^2$ test, t-test, and stepwise multiple regression using SPSS 18.0. Smartphone addiction-risk group was 97(27.0%) and general group was 261(72.9%). Smartphone addiction-risk group was more negatively perceived parenting attitude and higher academic stress than the general group. The most influential factors on addiction-risk group was using time in a day(${\beta}=.29.4$, p=.003) and general group was academic stress(${\beta}=.298$, p=.000). It is important to develop an intervention program to prevention the smartphone addiction according to the classification of addiction-risk group.

Background: Medication-related problems (MRPs) frequently occur during the discharge period. Elderly patients, particularly, are at high risk for these problems due to polypharmacy and the use of potentially inappropriate medications. The purpose of this study was to build and implement collaboration between general hospital and community pharmacies to address MRPs among high-risk elderly patients before/after discharge. Methods: This retrospective study was conducted between June and December of 2020. The inclusion criteria were patients with aged ≥65 years; residents of Jeonju; discharged from Jeonbuk National University hospital; either on medication of exceeding 10 medications (or high-risk medications) after hospitalization through the emergency room, or having severe illness. Patients received medication reconciliation and counselling by hospital pharmacists before discharge and home-visit pharmaceutical care as follow-up by community pharmacists after discharge. Results: Twenty-two patients agreed to home-visit pharmaceutical services. Fifteen and 11 patients completed the first and second home-visit pharmaceutical care service, respectively. Forty-two MRPs were identified in 15 patients. The types of high-frequency MRPs were incorrect administration of drug, adverse drug reactions, medication non-compliance, drug-drug interactions, lifestyle modifications, and expired medication disposal. After consultation with the pharmacist, 34 out of 42 MRPs were resolved. Conclusions: Transitional care for high-risk elderly patients before and after discharge was successfully built and implemented through a collaboration between general hospital and community pharmacies. This study suggests that home-visit pharmaceutical services may have positive effects on the safe use of drugs during the transition period; however, additional research is needed to expand on these findings.

By assuming a general progressive Type-II censored sample, we propose the minimum risk estimator (MRE) and the approximate maximum likelihood estimator (AMLE) of the scale parameter of the one-parameter exponential distribution. An example is given to illustrate the methods of estimation discussed in this paper.

We consider the question of efficiency of the Bayes sequential procedure with respect to the optimal fixed sample size Bayes procedure in a simple vs. simple testing problem for data coming from a general nonregular density b(.theta.)h(x)l(x < .theta.). Efficiency is defined in two different ways in these caiculations. Also, the minimax sequential risk (and minimax sequential stratage) is studied as a function of the cost of sampling.

We consider a general compound Poisson risk model in which the premium rate is surplus dependent. We analyze the joint distribution of the surplus immediately before ruin, the deffcit at ruin and the time of ruin by solving the integro-differential equation for the Gerber-Shiu discounted penalty function.

This paper provides a new theoretical rationale for public procurement for innovation (PPI), a unique policy encouraging public procurers to purchase innovative products. In contrast to existing studies that primarily emphasize the advantages of PPI, this paper takes a comprehensive approach, examining both the costs and risks associated with PPI, alongside its benefits. It finds a general condition under which PPI outperforms traditional public procurement. Under this condition, this paper demonstrates that PPI enhances social welfare by facilitating optimal risk-sharing between public procurers and the general economy. Additionally, it draws policy implications from a comparative analysis between the current PPI policy in Korea and an optimal PPI policy.

Purpose: The purpose of this study was to determine core nursing intervention in nursing records and to compare perceived nursing intervention priority and nursing intervention frequency of general surgery department. Methods: Subjects were 70 nurses who work in the general surgery department. Data was collected using a nursing intervention classification and analyzed by frequency and mean. Results: The most frequent nursing interventions of nursing records were orderly risk management, coping assistance, tissue perfusion management, skin/wound management and nutrition support. Important nursing interventions were tissue perfusion management, respiratory management, electrolyte acid-base management, elimination, peri-operative care. The most frequent nursing interventions were drug management, peri-operative care, risk management, tissue perfusion management, patient education. Conclusion: This study found that nursing records were different from intervention priority and nursing frequency. So further study is needed for finding focused intervention of specific subjects and differences with priority of nursing and frequency of nursing.

Tracheobronchial injury (TBI) is an uncommon but potentially fatal event. Iatrogenic lesions during bronchoscopy, endotracheal intubation, or thoracic surgery are considered the most common causes of TBI. When TBI is detected during surgery, concomitant surgical treatment is recommended. Herein we present a case of successful robotic primary repair of iatrogenic tracheal and left bronchial branch tears during a robot-assisted hybrid 3-stage esophagectomy after neoadjuvant chemoradiotherapy. A robotic approach can facilitate the repair of this injury while reducing both the potential risk of conversion to open surgery and the associated increased risk of postoperative respiratory complications.

Risk financing is defined as the methods applied to fund risk treatment and the financial consequences of risk. It is a major component of the transfer of risk and the retention of risk which are, in turn, parts of the risk treatment process. This study applied the general guidelines on risk financing to product liability risk. Product liability risk occurs when potential defects in the process of design, production, and distribution lead to accidents resulting in fatal, financial, and environmental loss. Risk on product liability may be financed in many different ways, each of which may be used singularly or in combination. The most popular and recommendable way suggested in the guidelines is the retention or use of reserves, transfer, credit or insurance.

This paper describes introductory remarks on risk management and risk-based design for ships and offshore installations with potential hazards. Clients' requirements on safety and performance was related to the risk management and risk-based design. A general procedure for risk-based design was also suggested with each step explained in detail. Various risk-based design approaches were emphasized with their needs and methodological characteristics taken into account. Related rules, standards, and regulations were summarized. The last part included recommendations for Korean ship building industries about the risk management and risk-based design.
