During maritime distress, Korean Coast Guard investigates the current status of the distress, such as identifying search objects, to establish a search plan. The ship master is required to submit a report to the competent authority before departure, along with an identity list of the crew and passengers. As a list of the passengers on board is made manually, the waiting time becomes longer, and it is difficult to immediately identify these during maritime distress. The Ministry of Oceans and Fisheries has developed an app to make it easier to register for boarding, but it has been inactive for various reasons. Therefore, this study proposed a plan to improve it. By activating the mobile-phone boarding report system, it is possible to quickly secure the initial location and time of the person in water and provide mental relief to them by acknowledging the receipt of a distress report. In addition, using this information, it is possible to quickly rescue the affected person through public-private partnership.

Objectives : The aim of this study is to review clinical trials using Qigong exercise on patients with hypertension and to assess their methodology and results. Methods : Electronic literature searches for clinical trials (randomized trial, non-randomized trial, before-after study) of Qigong exercise were performed in 21 electronic databases (5 international databases and 16 Korean databases). English, Korean or Chinese articles were included. Laboratory or animal studies were excluded. Results : A total of 11 studies met the inclusion criteria. Five randomized controlled trials, Four non-randomized trials and two before-after studies were included. Seven studies used self-developed Qigong exercise. Two studies used Guolin Qigong exercise and two studies used Qigong exercise with an anti-hypertension drug. Of the nine randomized trials or non-randomized trials, four studies used an anti-hypertension drug control and three studies used waiting list controls. Compared to baseline, a change in blood pressure after the Qigong exercise treatment was significant in all studies. However, the results effect of blood pressure between Qigong exercise and controlled trials were not consistent. Conclusions : There are low-quality clinical trials of Qigong exercise for hypertension. To evaluate the effects of Qigong exercise, more rigorous trials are warranted.

This study is to investigate cardiotonic effect of acupuncture on heart rate variability(HRV) analyzed by a nonlinear way(DFA, Detrended Fluctuation Analysis). It was designed as a randomized, single-blind, waiting list-controlled, cross-over study. We assessed heart rate and R-R intervals in Circadian electrocardiography with a Holter monitoring device for twelve hospitalized participants. The compatible analytical program, Zymed, was used for generating the signals of R-R intervals from 24 hour-ECG. In DFA analysis, we produced DFA alpha 1, alpha 2 parameters according to the process of Cygwin module of Linux server. We tested if there was any difference between HRV parameters using SPSS, a statistical package. There was no difference between acupuncture and no treatment group in DFA alpha 2 parameter {95% Confidence Interval (-)0.058 - 0.037, P = .565}. Two group all showed large intra-individual variations. Consequently, acupuncture treatment did not modulate the complexity of HRV in a DFA analysis. This study can be a rationale for acupuncture's properties on cardiovascular and autonomic systems.

An 8-year-old girl diagnosed with dilated cardiomyopathy and Russell-Silver syndrome was admitted to our pediatric intensive care unit due to low cardiac output and multiple-organ dysfunction. The patient was placed on the heart transplant waiting list and extracorporeal membrane oxygenation was performed as a bridge to transplantation. After 17 days, heart transplantation was performed. The donor was a 46-year-old female (weight, 50 kg; height, 150 cm). The donor:recipient weight ratio was 3.37:1. Because the dimension and volume of the recipient's thoracic cage were insufficient, the sternum could not be closed. Nine days after transplantation, the patient underwent delayed sternal closure. To obtain adequate space, we left the sternum 4.5 cm apart from each margin using four transverse titanium plates. A transverse rectus abdominis musculocutaneous flap was chosen to cover the wound. Due to the shortage of donors, a size-mismatched pediatric heart transplantation is sometimes unavoidable. Closure of the opened sternum of a transplant recipient can be challenging. Sternal reconstruction after an extremely oversized heart transplantation with transverse titanium plate fixation and a musculocutaneous flap can effectively achieve sternal closure and stability.

Automation ensures accurate and well-organized container transportation in container terminals. This paper addresses operational issues such as equipment scheduling and the coordination between various pieces of equipment in a rail-based automated container terminal. Containers are relayed using multiple types of equipment from road trucks to a vessel and vice versa. Therefore, handshaking is required during a container transfer between different pieces of equipment. Synchronization between the schedules of all the equipment is important to reduce equipment waiting times and the time required for transporting containers, which results in a short turnaround time for a vessel. This paper proposes an integrated control system with the objective of synchronizing the operations of different types of equipment, provides a list of decisions to be made by the control module of each type of equipment, and shows all the required information transfers between control modules. A scheme for the integrated scheduling of multiple types of equipment is proposed. The decisions made by each control module in a real-time fashion are listed with detailed explanations, and the information transfer between managers in a real-time situation at the proposed terminal is described.

Purpose: The purpose of this study was to examine the effects of auricular acupressure on headaches and its impact on daily activities in nurses. Methods: The design of this study was a randomized controlled trial. Data were collected from April 1 to April 14, 2022. Nurses suffering from headaches were recruited from a hospital in a city. Twenty nurses were assigned to the experimental group and 20 nurses to the control group. The experimental group received auricular acupressure for 2 weeks, and the control group was put on the waiting list. Results: Auricular acupressure reduced headache over 2 weeks compared to the control group. Auricular acupressure reduced the effect of headache on daily activities compared to control group. Headache effect on daily activities in the control group did not change. Conclusion: Based on the results of this study, it is suggested to repeat the study using various combinations of acupressure points other than the acupressure points used in this study or to use participants other than nurses.

Background: The purpose of this systematic review was to investigate the effects of digital therapeutics for insomnia on sleep disorders and mental health improvement compared to the control group. Methods: Following the guidelines on systematic review(PRISMA, NECA), a literature search was conducted through PubMed, Cochrane Library, EMBASE, RISS, KISS, and KoreaMed using keywords. The Cochrane Risk of Bias Tool and Review Manager version 5.3 were used for risk of bias and effect size assessment. Results: Thirty eight RCT met criteria for inclusion. When compared against three control conditions, the digital therapeutics for insomnia was an effective intervention for improvement sleep disorders and mental health in comparison to waiting list and Patient-directed care with some intervention by medical staff. However, digital therapeutics for insomnia were no more effective than face-to-face CBT-I control group. Conclusion: The efficacy of digital therapeutics for insomnia was evaluated differently depending on the control group. Therefore, in phase 3 clinical trials for efficacy evaluation, it is necessary to review whether the control group has been properly established.

The purpose of this study was to examine the effects of variables of interest on mothers' choices of infant care. The variables of interest in this study were categorized into the following three areas: 1) demographic characteristics of mothers and infants, 2) structural and procedual dimensions of infant care facilities, and 3) maternal beliefs on child-rearing. The subjects of this study were mothers whose infants were currently cared by at infant care facilities(n=185) and those who were on the waiting list to use non-maternal infant care(n=53). The main results of this study were as follows. First, mothers of this study preferred to select a type of center-based subsidized infant care over other types of care(family day care) due to quality of the program. Second, the mothers who were not using infant care and cared for their infants at homes reported that there were limitations in their choices of types of infant care due to accessibility and availability of public subsidized infant care facilities, and their child rearing goals were more likely to emphasize learning achievement and maturity than character education or personality. The mothers were more likely to choose a family home care over center-based public subsidized care when they were employed, had younger infants, had longer period of time on waiting lists, and emphasized structural dimensions of infant care than center-based care users. Implications for research and practices were discussed along with the main results of this study.

Based on an analysis of the characteristics of "Ecute" of the East Japan Railway Company (JR East) that planned the world's first large scale commercial facilities inside a ticket gate (paid-area including waiting room and platforms), the present study proposes a brand development of commercial facilities inside aged railway stations, where only basic railway business have been provided focusing on passenger transportation, by renewing the definition of railway commercial facilities and presenting a detailed planning and the direction of the operation system. A list of practical tasks that can be carried out in academia, planning and operation / management to facilitate the revitalization of the use of commercial facilities inside railway stations are as follows: 1) the setting of a wide scope for the revitalization of railway commercial facilities around the railway station focusing on private-funded stations in addition to existing stations; a setup of the direct scope of commercial development in the practical railway operation for passengers and stations in terms of external research, and a corresponding shift in thinking in terms of internal research 2) development of under used spaces such as the transfer area (Gongdeok Seoul Wangsimri Station are first target stations where more than four subway lines intersect) 3) brand establishment through improvement strategies for image and symbolism specialized for railway stations 4) rent of suitable business stores and layout of commercial facilities by analysis of passenger move pattern 5) development of commercial facilities which can attract customers by displaying various products, as well as finding a way to develop them in to a base facility that connects to local infrastructures 6) providing advertisement and management system for continual maintenance, and 7) brand specialization through unique storytelling and design plan that stimulates sensibility. The above study results can be utilized as a starting point for design brand awareness about commercial facilities in railway stations in Korea, which can be developed further to improve station image and passenger convenience, as well as to increase the revenue of railway businesses.
