South Korea’s national healthcare system after liberation often described as transformation from ‘sanitation’ to ‘public health’. The U.S. military government introduced public health nursing as the primary vehicle for communicating the newly introduced concept of public health to the Korean public. This meant that nursing, which had been in a subordinate position within the healthcare system during the Japanese occupation, had to be repositioned within the healthcare system as an independent and leading professional agent of healthcare. At the same time creating positions for public health nurses within the newly envisioned health center system, and convincing the public that nurses were the primary agents of public health activities. Yet, in resource limited setting, the role of public health nurses was significantly scaled back. Initial plans for institutionalized, community-wide health care through home visits shifted to addressing the challenges facing Korean society, including maternal and child health and infectious disease prevention. Ironically, the expansion of health centers during late 1950s diminished the position of public health nurses within local government health systems, who were gradually replaced by male administrative staff. The role of public health nurses was greatly curtailed in the 1960s, but they laid the groundwork for later community nursing and health care efforts. At the same time, public health nurses were assigned with new role of ‘visiting’ local health centers for observation, education, and management. Public health nursing allows to look beyond the ideological and institutional dimensions to examine how new concepts and practices of “public health” were actually transmitted to communities in post-liberation Korea.

As being obesity is associated with numerous health problems, effective fat loss strategies are required. Although dieting has been the major fat loss method, aerobic exercise programs have been shown to increase cardiorespiratory fitness and preserve fat-free mass. Most aerobic exercise interventions have consisted of moderate-intensity steady-state exercise. Disappointingly, these kinds of exercise programs have resulted in minimal fat loss. In contrast, high-intensity intermittent exercise (HIIE) has been shown to result in greater fat loss. Accumulating evidence suggests that high intensity intermittent exercise (HIIE) has the potential to be an economical and effective exercise protocol for reducing fat of overweight individuals, especially Tabata workout and Crossfit.

Purpose: This study aimed to explore the constructs and context of hospital nurses’ organizational silence. Methods: In-depth interviews were conducted with 17 nurses in small-middle general hospitals as well as big university hospitals. We then derived the key themes using grounded theory method. Results: Nine themes and 30 sub-themes were derived: “Willing to be recognized for performance rather than saying”, “Getting used to the hard-to-speak climate”, “Face the reality that does not change when said”, “Complicated situation that prevents self-regulating decision-making”, “Conflicts that are difficult to confront”, “Unfair responsibilities that I want to evade”, “Leaders who don’t support me”, and “Being blocked in communication”. Consequently, the nurses learned to adopt a climate of silence and “learned organizational silence” behavior. They experienced that prosocial silence was essential for obtaining approval as a member of the group, and defensive silence for protecting themselves in the hierarchical structure and unfair responsibilities. Acquiescent silence originated from a futile relationship with their supervisors, one-way communications, and the unsupportive management system, in which three types of silence appeared sequentially or in combination with each other. Conclusion Based on these results, nursing managers should identify the context of nurses’ organizational silence and should lessen these silence behaviors.

Liver cell adenoma is uncommon and most often affects women of reproductive age; it is often associated with use of oral contraceptives. It is a very rare benign tumor of the liver in males and associated with use of anabolic steroids or glycogen storage disease type I. The surgical treatment remains controversial. We experienced 3 cases of male liver cell adenoma without use of anabolic steroids or glycogen storage disease. We performed right lobectomy of liver in 2 cases of mass on right lobe and performed mass enucleation with cholecystectomy in another case of mass on left medial segment.

PURPOSE: This study aimed to examine the process from occurrence of a hospital nurse's suicide to workers' compensation approval, responses of the parties involved, issues debated during approval deliberations, and significant policy changes resulting from the incident.METHODS: We conducted in-depth interviews with involved parties and collected various documents, including newspaper articles, forum proceedings, and the agency report on determination of workers' compensation. Content analysis was performed on the collected data.RESULTS: A Joint Task Force continuously reported its progress and findings through mass media such as newspaper, radio, and TV. These activities exerted pressure on a government agency to conduct an occupational disease review and significantly impacted the workers' compensation approval. The agency recognized associations between the hospital's inadequate nurse training and the suicide but did not confirm the excessive overtime and workplace harassment experienced by the nurse as causes of the suicide. This case's media coverage and impact resulted in a law prohibiting workplace harassment and a hospital system dedicating at least one nurse to training activities.CONCLUSION: This incident had a significant social impact as the first case of workers' compensation approval for a hospital nurse's suicide. However, the case produced no structural changes in nurses' working conditions such as heavy workloads.

Purpose: This study examined health determinants at a community level and put forward to a typology of five different forms of community health vulnerabilities. We also investigated the differences in the prevalence of chronic diseases, self-rated health, and quality of life (EQ-5D) among the five types. Methods: Latent class analysis was applied to material, social capital, and health behavior vulnerability variables across 255 regions of South Korea. The data came from 2017 & 2019 Community Health Survey. Results: We found five types of community health vulnerabilities: Type 1 group had the highest material vulnerabilities compared to Type 5. The typology was found to be significant in all the regression analysis on the prevalence of chronic diseases (hypertension and diabetes), self-rated health status, and quality of life. In the regions with high material vulnerabilities, the material vulnerability appeared the most effective to the health status of individual’s. In the other regions with less material vulnerabilities, the social capital and health behavior resources were found to be effective. Conclusion A comprehensive measure of vulnerability can be helpful to understand community health. Policy makers need to consider the level of material vulnerability when planning for a health promotion project.

STATEMENT OF PROBLEM: Problem of matching the appearance of porcelain restorations with the patient's natural dentition has always been a concern to dental clinicians. Recently, demands for esthetics, even in restorations requiring strength, has brought a revolution to dentistry and increased use of zirconia. Among the various factors, shade and translucency of the core can significantly affect the overall esthetics of the restoration and should be considered when selecting an all-ceramic system. PURPOSE: The purpose of this study was to spectrophotometrically evaluate the influence of different zirconia systems and core thickness on the final shade of all-ceramic restorations using the CIEL*a*b* system. MATERIAL AND METHODS: Core specimens (n = 20 per group) of In-Ceram Alumina, In-Ceram Zirconia, Digident CAD/CAM Zirconia, Cercon Zirconia were fabricated 20mm in diameter. 10 specimens of each group were fabricated at core thickness of 0.5mm and 0.7mm. These core specimens were veneered with shade A1 and A3 porcelain of the recommended manufacturer. CIEL*a*b* coordinates were recorded for each specimen with a spectrophotometer (Model CM-2600d, Minolta, Japan). Color differences were calculated using the equation delta E*=[(delta L*)2+(delta a*)2+(delta b*)2]1/2. RESULTS: 1. Specimens of core thickness 0.5mm and 0.7mm did not exhibit clinically perceived color difference. 2. Regarding shade reproducibility, In-Ceram Alumina and In-Ceram Zirconia showed significant difference within each group. 3. Cercon Zirconia group showed the highest L* value and Digident Zirconia group showed lowest a* and b* value. 4. Generally, the shade difference between materials was higher in the A3 shade group than in the A1 shade group. CONCLUSION: Within the limitations of this study, there was no color difference after increase in core thickness and every all-ceramic system has color characteristics that clinicians have to consider when selecting materials. Also, manufacturers of different porcelain systems must make every effort to achieve color reproducibility.

BACKGROUND: Although a laparoscopic cholecystectomy results in less pain than an open cholecystectomy, it is not a pain-free procedure. Therefore, this study was conducted to determine whether perioperative intravenous lidocaine would reduce postoperative pain after a laparoscopic cholecystectomy. METHODS: Fifty patients undergoing laparoscopic cholecystectomy were divided into two groups; a lidocaine group, in which patients were injected with a lidocaine bolus (1.5 mg/kg) and infusion (1.5 mg/kg/h); and a control group, in which patients were injected with the same volume of saline bolus and infusion. Intravenous lidocaine was initiated before anesthesia was administered and continued for 1 hour postoperatively. The intensity of abdominal and shoulder pain was then assessed 1, 6, 12 and 24 hours after surgery and recorded using a visual analog pain score (VAS) and verbal rating score (VRS). RESULTS: The abdominal pain score (VAS and VRS) was significantly lower in the lidocaine group than in the control group at all times evaluated during the first 24 hours after surgery (P < 0.05). In addition, the shoulder pain score and incidence were significantly lower in the lidocaine group than the control group at 12 hours and 24 hours after surgery (P < 0.05). In the lidocaine group, the incidences of epigastric, right flank, and back pain were lower than that of the control group, but these differences were not statistically significant. CONCLUSIONS: Perioperative intravenous lidocaine reduces shoulder and abdominal pain for 24 hours after laparoscopic cholecystectomy.
