The safety and storage periods of various foods, including dairy products, can be affected by a variety of internal and external factors. Therefore, all foods have a risk of deterioration after storage for a certain period of time for many different reasons. Among dairy products, cheese is enriched in necessary nutrients; however, it can also easily undergo physical, chemical, and biochemical changes under various conditions. Therefore, the storage period of cheese is an important issue. If various factors that can affect the safety and storage period of cheese can be controlled, the safety of cheese can be preserved and its storage period extended. This review of the literature published on the issue summarizes various state-of-the-art technologies currently used to extend the storage period of cheese without affecting its quality. This basic data will inform future research concerning the storage period of various cheeses.

The objective of this study was to investigate the nutritional status, biochemical parameters, lipid and electrolytes concentrations of the enteral nutrition patients according to the duration of enteral nutrition. Eighteen neurosurgery patients in the intensive care unit (ICU) at K University Hospital were subjected in this study. The duration of enteral nutrition was classified into under or over six month of period. Anthropometric, biochemical, clinical, and dietary assessments were performed. Patients' intakes of energy and protein were insufficient, from 82% to 95% of their requirements. Mid-arm muscle circumference (MAMC) and mid-am muscle area (MAMA) were significantly lower in patients over six months of enteral nutrition than those in patients under six months. The subjects were malnourished as indicated by nutrition-related parameters such as hemoglobin, albumin, total lymphocyte count (TLC), tricep skinfold thickness (TSF), mid-arm circumference (MAC), MAMC, and MAMA. Serum chloride level of the patients eve, six months of enteral nutrition was lower (94.7 $\pm$ 3.4 mmo1/1) significantly as compared to that of patients (99.3 $\pm$ 3.5 mmol/ 1) under six months. Urinary sodium and chloride levels were lower in the longer time of enteral nutrition patients than those of shorter period of enteral nutrition patients (p < .05). While serum phospholipid level was higher in the patients over six months of enteral nutrition, other blood biochemical parameters and electrolyte concentrations did not show any differences with the duration of enteral nutrition. Neurosurgery patients in the ICU undergoing long-term enteral nutrition tube-feeding were malnourished and had a variety of metabolic complications. The duration of enteral nutrition could affect the patients' nutritional status, biochemical parameters, and electrolytes balance. The patients who require nutritional support over an extended time need the continuous follow-up care and monitoring by the nutrition support team for laboratory, clinical, and nutritional assessments.

Background: According to the National Family Health Survey-4, in India, 78.9% of deliveries occur in institutions, although only 42.6% of new mothers initiate breastfeeding within 1 hour of delivery. Purpose: To estimate the proportion of early initiation of breastfeeding (EIBF) among new mothers at discharge from a tertiary care hospital and identify the determinants of delayed initiation of breastfeeding among them. Methods: This was a hospital-based analytical cross-sectional study of 108 new mothers. After obtaining Institutional Review Board approval and informed consent, we interviewed the new mothers on the day of discharge. Multivariate logistic regression was performed using IBM SPSS Statistics ver. 24. Results: The median breastfeeding initiation time was 90 minutes (interquartile range, 30-180 minutes). Overall, 43.5% of the mothers practiced EIBF, 77.4% practiced exclusive breastfeeding, and 43.5% were rooming in at discharge. Reasons for breastfeeding delays included extended recovery time from spinal anesthesia, maternal lassitude, and uncomfortable breastfeeding position due to post-cesarean pain. In the multivariate analysis, a birth weight less than 2,500 g (adjusted odds ratio [aOR], 4.33; 95% confidence interval [CI], 1.12-16.82; P=0.03), cesarean section delivery (aOR, 4.68; 95% CI, 1.57-13.92; P=0.005), and mother's poor knowledge of breastfeeding (aOR, 4.61; 95% CI, 1.44-14.72; P=0.010) were more likely to delay the initiation of breastfeeding. Conclusion: EIBF was practiced by less than half of the new mothers as determined by the cesarean section, baby's birth weight, and mothers' awareness of breastfeeding. Thus, it is vital to improve breastfeeding and nutritional counseling among mothers during the antenatal period and improve healthcare professionals' training to facilitate EIBF, even in circumstances such as cesarean section.

Graves disease (GD) is the most common cause of hyperthyroidism, accounting for more than 90% of cases in Korea. Patients with GD are treated with any of the following: antithyroid drugs (ATDs), radioactive iodine (RAI) therapy, or thyroidectomy. Most patients begin treatment with ATDs, and clinical guidelines suggest that the appropriate treatment period is 12 to 18 months. While RAI treatment and surgery manage thyrotoxicosis by destroying or removing thyroid tissue, ATDs control thyrotoxicosis by inhibiting thyroid hormone synthesis and preserving the thyroid gland. Although ATDs efficiently control thyrotoxicosis symptoms, they do not correct the main etiology of GD; therefore, frequent relapses can follow. Recently, a large amount of data has been collected on long-term ATDs for GD, and low-dose methimazole (MMZ) is expected to be a good option for remission. For the long-term management of recurrent GD, it is important to induce remission by evaluating the patient's drug response, stopping ATDs at an appropriate time, and actively switching to surgery or RAI therapy, if indicated. Continuing drug treatment for an extended time is now encouraged in patients with a high possibility of remission with low-dose MMZ. It is also important to pay attention to the quality of life of the patients. This review aimed to summarize the appropriate treatment methods and timing of treatment transition in patients who relapsed several times while receiving treatment for GD.

Due to major disasters Korea has been damaged, and they caused lots of casualties: for last ten years natural disasters caused 1288 deaths including missing people; human disasters including industrial disasters brought as many as 4,512.148 casual ties (126,372 deaths with 4,385,400 injuries); and they cost 44.1 trillion property damage. However, even though major disasters have brought about tremendous human loss and property damage, Koreas National Disaster Medical System to rescue casualties is insufficient, and it has not been activated. Fortunately, through major disaster management process, the National Disaster Management System has been developed, increasing its own efficiency, and resulting in to organize an Office of Firefighting and Prevention of Disasters under the central government. Considering the value of human lives, the disaster medical part, in the U.S.A. as well as in Korea, must have an independent organization in the government, not as one sector of the government department. It will have its own organizational structure, such as disaster planning, operation, and logistics, and interact with central and local government or between local government agencies. So each agency will cooperate and supply resources interchangeably. Also, with the system of disaster management and restoration, the disaster medical system must be advanced in keeping step. Its role must be extended due to the possibility of biological terror or SARS around the world, resulting in severe casualties. Korea has the Emergency Medical Service System based on the regulation of emergency medical care, yet it is a part of the National Disaster Management System. It must be managed independently apart from it. As we see the emergency medical technicians playing as the backbone in disaster medical care in the US, we should have legal foundations for Koreas emergency medical technicians, emergency medical providers, to participate in rescue operation actively. At the same time, we need to have a national register system to classify disaster medical resources, and a total plan to place resources according to the impact of disaster, and how to organize teams. We also need to draw up a scheme to activate civil disaster medical resources, as integrating public and private or voluntary organizations.

Purpose: The aim of this study was to investigate the satisfaction of newly graduated nurses with educational programs and their experiences in role transition. Methods: Data were collected from November 1 to December 15, 2018 and 483 new graduate nurses working at 15 tertiary hospitals and 10 general hospitals participated. For data collection, self-report questionnaires including the Casey-Fink Graduate Nurse Experience Survey tool and satisfaction with education were used. Data were analyzed using descriptive statistics, t-test, and one-way analysis of variance. Results: Satisfaction with education ranged from 3.09 to 3.27, and satisfaction with preceptors was 3.45(maximum 4). The skill that new nurses ranked as most difficult during the first 3 months was charting/documentation, and throughout a whole year, the top 4 difficult skills were cardiopulmonary resuscitation/emergency response, ventilator care, end-of-life care, and prioritization/time management. In comfort/confidence, new graduates felt most comfortable with support and least comfortable with patient safety. More than 50 percent of new graduates experienced stress during role transition, and the most frequently experienced stressors were related to job performance and personal life. Levels of satisfaction with education and comfort/confidence differed according to the hospital type and number of preceptors for new nurses. Conclusion: In order to facilitate the transition of new graduate nurses to professional nurse, an extended period of education, systematic and standardized transition programs, and continuous support during the first year of practice are required.

This study concerns especially Choryang-Weagwan which was the largest Japanese House left in Pusan through Chosun Dynasty. Choryang-Waegwan was known to have been jointly constructed by Korean and Japanese carpenters. Therefore, Weagwan was a place for exchange of architectural tradition (special features such as sliding door and straw mat) between Korean and Japan. Judging from this point of view, It is certain that mutual influences helped to shape architecture of Choryang-Weagwan. After establishment Choryang- Weagwan was gradually extended, owing to the prosperity of trade with Japan. But since late 18th century government of Chosun did not give as much care to maintaining Choryang- Weagwan as a result of deteriorating condition of commercial and diplomatic relations with Japan. From the beginning of Choryang- Weagwan construction, Superintendents of the construction were called Hun-do and Byl-cha, who acted as official interpreters as well. And, during construction works, they were called Gamdong-gwan, At the start of construction, Weagwan was built partly in Japanese-style by the carpenters from Tokugawa Shogunate. But as time passed, the participation rate of Japanese carpenters diminished gradually. After 1831, Japanese technician vanished extremely and repairing construction was continued by the Korean workers only.

Nano and micro structure-based biosensors are promising tool for label-free detection of biomolecular interactions with great accuracy. This review gives a brief survey on nano and micro platforms to sense a variety of analytes such as DNA, proteins and viruses. Among incredible nano and micro structure for bio-analytical applications, the scope of this paper will be limited to micro and nano resonators and nanowire field-effect transistors. Nanomechanical motion of the resonators transducers biological information to readable signals. They are commonly combined with an optical, capacitive or piezo-resistive detection systems. Binding of target molecule to the modified surface of nanowire modulates the current of the nanowire through electrical field-effect. Both detection methods have advantages of label-free, real-time and high sensitive detection. These structures can be extended to fabricate array-type sensors for multiplexed detection and high-throughput analysis. The biosensors based on these structures will be applied to lab-on-a-chip platforms and point-of-care diagnostics. Basic concepts including detection mechanisms and trends in their fields will be covered in this review.

Purpose: This study aims to examine the effects of nursing interventions based on the Extended Theory of Planned Behavior (ETPB) regarding self-efficacy for exercise (SEE), physical activity (PA), physical function (PF), and quality of life (QOL) in patients with lung cancer who have undergone pulmonary resection. Methods: This quasi-experimental study was conducted between July 2015 and June 2018 in two university-affiliated hospitals. The intervention included pre-operative patient education, goal setting (action and coping planning), and feedback (behavior intention and perceived behavioral control). The intervention group (IG) (n=51) received nursing interventions from the day before surgery to 12 months after lung resection, while the comparison group (CG) (n=36) received usual care. SEE, PA, PF (dyspnea, functional status, and 6-minute walking distance [6MWD]), and QOL were measured before surgery and at one, three, six, and 12 months after surgery. Data were analyzed using the χ² test, Fisher's exact test, Mann-Whitney U test, t-test, and generalized estimation equations (GEE). Results: There were significant differences between the two groups regarding SEE (χ²=13.53, p=.009), PA (χ²=9.51, p=.049), functional status (χ²=10.55, p=.032), and 6MWD (χ²=15.62, p=.004). Although there were no time or group effects, the QOL mental component (Z=-2.78, p=.005) of the IG was higher than that of the CG one month after surgery. Interventions did not affect dyspnea or the QOL physical component. Conclusion: The intervention of this study was effective in improving SEE, PA, functional status, and 6MWD of lung cancer patients after lung resection. Further extended investigations that utilize ETPB are warranted to confirm these results.
