This study was accomplished to investigate the dietary life and their opinion about the food-nutrition labelling of 20's∼60's housewives in Seoul and Kyeonggi area. The results were as follows. Among subjects, 63.5% didn't make a budget for the food expenses because they did not practice habitually not only the budget-planning, but also the menu planning. They often brought the Kimchi from the relatives rather than preparing it by themselves. On the other hand, they often purchased the soy sauce, soybean paste and soybean paste mixed with red pepper. When purchasing the foods, the importantly considered factors were in the order of freshness, taste and nutritional quality. They thought the processed foods were convenient and economic in terms of time but were not beneficial for the health and low in the nutritional quality. The confirming degree of food-nutrition labelling was very low, but in case of confirming, they often confirmed the manufactured date and the expiration date in order to confirm the stability. The degree of confidence and understanding about food-nutrition labelling of subjects was average 3.3 out of 5. They wanted the nutrient content the most in the food-nutrition labelling on the package. They preferred it as the types of picture and graph rather than the table and descriptiption. The expected effects of food-nutrition labelling was that they might be helpful to select the foods for the prevention of the adult diseases and obesity. From the results, we proposed that the agencies and nutrition concerned consumers should make an every efforts for the successful implementation of food-nutrition labelling system.

The prevention of cancer is one of the most important public health and medical practices of the $21^{st}$ century. We have made much progress in this new emerging field, but so much remains to be accomplished before widespread use and practice become common place. Cancer chemoprevention encompasses the concepts of inhibition, reversal, and retardation of the cancer process. This process, called carcinogenesis, requires 20-40 years to reach the endpoint called invasive cancer. It typically follows multiple, diverse and complex pathways in a stochastic process of clonal evolution. These pathways appear amenable to inhibition, reversal or retardation at various points. We must therefore identify key pathways in the evolution of the cancer cell that can be exploited to prevent this carcinogenesis process. Basic research is identifying many genetic lesions and epigenetic processes associated with the progression of precancer to invasive disease. Many of these early precancerous lesions favor cell division over quiescence and protect cells against apoptosis when signals are present. Many oncogenes are active during early development and are reactivated in adulthood by aberrant gene promoting errors. Normal regulatory genes are mutated, making them insensitive to normal regulatory signals. Tumor suppressor genes are deleted or mutated rendering them inactive. Thus there is a wide range of defects in cellular machinery which can lead to evolution of the cancer phenotype. Mistakes may not have to appear in a certain order for cells to progress along the cancer pathway. To conquer this diverse disease, we must attack multiple key pathways at once for a predetermined period of time. Thus, agent combination prevention strategies are essential to decrease cancer morbidity. Furthermore, each cancer type may require custom combination of prevention strategies to be successful.

Many teachers report familiarity with and adherence to reform ideas, but their actual teaching practices do not reflect a deep understanding of reform. Given the challenges in implementing reform, this study intended to explore the breakdown that may occur between teachers' adoption of reform objectives and their successful incorporation of reform ideals. To this end, this study compared and contrasted the classroom social norms and sociomathematical norms of two United States second-grade teachers who aspired to implement reform. This study is an exploratory, qualitative, comparative case study. This study uses the grounded theory methodology based on the constant comparative analysis for which the primary data sources were classroom video recordings and transcripts. The two classrooms established similar social norms including an open and permissive learning environment, stressing group cooperation, employing enjoyable activity formats for students, and orchestrating individual or small group session followed by whole group discussion. Despite these similar social participation structures, the two classes were remarkably different in terms of sociomathematical norms. In one class, the students were involved in mathematical processes by which being accurate or automatic was evaluated as a more important contribution to the classroom community than being insightful or creative. In the other class, the students were continually engaged in significant mathematical processes by which they could develop an appreciation of characteristically mathematical ways of thinking, communi-eating, arguing, proving, and valuing. It was apparent from this study that sociomathematical norms are an important construct reflecting the quality of students' mathematical engagement and anticipating their conceptual learning opportunities. A re-theorization of sociomathematical norms was offered so as to highlight the importance of this construct in the analysis of reform-oriented classrooms.

The Japanese housing market has implemented management and operation systems of community service ahead of the Korean market. This paper examines case studies of Japanese community services by reviewing related studies, studying homepages, and conducting in-depth interviews with management staff. The goal of this study is to find marketing strategies and the proper management practices in preparation for the upcoming low-fertility and aging society. The results of this study are as follows: 1) After Japan's bubble economy burst in 1985, so called that incorporated various community facilities with life services were introduced to the Japanese housing market in order to cope with the diversifying family types and lifestyles. This new trend was also due in part to customers' increasing demands for convenient urban condominiums. 2) In Japan, many developers and construction companies have run the management of community service programs and created new business models in collaboration with other affiliated companies. However, many of these programs have been found even more successful and reliable when the facility management companies collaborate with local service providers instead of relying solely on affiliated companies. 3) The early stage of life services began with "front-desk services", but these have evolved into more upgraded "concierge services" that can provide residents with tailored services and conveniences. Furthermore, some of the service providers have encouraged resident participation in the process of designing and implementing their community services. 4) In Korea, most construction companies and developers are still oriented toward providing hardware such as spaces and facilities in developing their community services. Therefore, companies with high market reputations must seek alternative ways to maintain and enhance their brand values by implementing new approaches in collaboration with both affiliated companies and local service providers. This can be done by finding new notions of managing and operating community services through research and development.

Background: We started postoperative pain management service using an intravenous patient-controlled analgesia (IV-PCA, PCA), which is known as convenient and effective analgesic method. In this report, we describe the efficacy and safety of PCA and the experience of developing an acute pain service to treat postoperative pain using a PCA. Methods: Practices of an acute pain service were started at a ward for general surgery after preparation of the standardized protocols for PCA. In each patient, PCA was connected following administration of initial loading doses of analgesics at recovery room after operation. All patients were checked by acute pain service team once or twice daily. The scope of acute pain service was gradually spread to other departments such as orthopedic, thoracic, obstetric and gynecologic departments by requests of patients or surgeons. We managed 1,590 patients during first 22 months. among them, nine hundred seventy two cases were prospectively evaluated for their analgesis efficacy and side effects of PCA. Results: The number of patients was increased day by day. the most common type of operation was gastrectomy (21.6%). Commonly used analgesics were nalbuphine (59%) and morphine (37%). The mean duration of PCA attachment was 3.3 days. The degree of analgesia on operation day was good in 44.8% and tolerable in 52.6% of patients. Only 3.9% of patients complained severe pain during their postoperative periods. One elderly patient experienced respiratory depression (0.06%) owing to accidental misuse of PCA by his relatives. Overall patient's satisfaction was over 93%. Conclusion: According to our experiences, we conclude that PCA is an effective, relatively safe and highly satisfactory method for postoperative pain management. Because of these advantages of PCA, the creation of our acute pain service using a PCA was successful and expanded rapidly.

Purpose: Functional constipation (FC) is a common gastrointestinal (GI) problem affecting children's well-being and quality of life. Although polyethylene glycol (PEG) is recommended as the first line therapy, it is not always applicable in lower socioeconomic populations. Hence, this study aimed to compare clinical courses of FC in children treated with different medications in order to identify prognostic factors related to treatment outcomes. Methods: We reviewed the medical records of patients aged ${\leq}15$ years diagnosed with FC according to the Rome IV criteria from 2007 to 2015 at the GI clinic, Songklanagarind Hospital. Baseline characteristic, medical history, and treatment outcomes were collected at first and subsequent visits. Results: Exactly104 patients (median age at diagnosis, 2.8 years) were diagnosed with FC. The number of follow-up visits per patient ranged from 1 to 35. The median duration of follow-up was 18.0 months (range, 6.0-84.2 months). PEG was given to 21% of patients. During the follow up period, 76% of patients experienced first recovery with a median time to recovery of 9.8 months. There were no significant differences in time until first recovery and relapse between patients who received and those who did not receive PEG (p=0.99 and 0.06, respectively). Age >6 years, normal defecation frequency, no history of cow's milk protein allergy, and use of laxatives were associated with successful outcomes. Conclusion: Treatment outcomes between patients who had and never had PEG demonstrated no significant difference in our study. Hence, current practices in laxative prescriptive patterns may be effective.

The objective of this study is to discuss the role of integrative medicine (IM) in contemporary health care settings, and how and which factors affect and facilitate the success of IM in terms of the integration of complementary and alternative medicine (CAM) and conventional medicine in primary health care (PHC). IM is meant to provide the best possible health care, for both patient and physician. The way of IM use in the developed countries presents various ways that IM can be provided, and it appears that strategies have been successfully developed to facilitate integration. Although few of the barriers to the integration of CAM and conventional medicine have been resolved, concerns over the legitimacy of CAM in health care (e.g., safety, biomedical evidence, and efficacy) are being overcome by the use of evidence-based practice in IM delivery. There are dominant models of IM that have been developed. The model types signify different levels of equity between CAM and conventional medicine in regard to the power, autonomy, and control held by each. However, the factors common to all IM models, whether describing CAM as supplementary or complementary to conventional medicine, is the concept of a health care model that aspires to be client-centred and holistic, with focus on health rather than disease as well as mutual respect among peer practitioners. Finally, this study concluded that the growth and viability of traditional Korean medicine(TKM) depend on evidence-based practices and identifying the successful influences on the integration of TKM and conventional medicine for recognition of its inherent value in PHC. Some recommendations for the integration of TKM and conventional medicine were suggested.

A nerve block is an effective tool for diagnostic and therapeutic methods. If a diagnostic nerve block is successful for pain relief and the subsequent therapeutic nerve block is effective for only a limited duration, the next step that should be considered is a nerve ablation or modulation. The nerve ablation causes iatrogenic neural degeneration aiming only for sensory or sympathetic denervation without motor deficits. Nerve ablation produces the interruption of axonal continuity, degeneration of nerve fibers distal to the lesion (Wallerian degeneration), and the eventual death of axotomized neurons. The nerve ablation methods currently available for resection/removal of innervation are performed by either chemical or thermal ablation. Meanwhile, the nerve modulation method for interruption of innervation is performed using an electromagnetic field of pulsed radiofrequency. According to Sunderland's classification, it is first and foremost suggested that current neural ablations produce third degree peripheral nerve injury (PNI) to the myelin, axon, and endoneurium without any disruption of the fascicular arrangement, perineurium, and epineurium. The merit of Sunderland's third degree PNI is to produce a reversible injury. However, its shortcoming is the recurrence of pain and the necessity of repeated ablative procedures. The molecular mechanisms related to axonal regeneration after injury include cross-talk between axons and glial cells, neurotrophic factors, extracellular matrix molecules, and their receptors. It is essential to establish a safe, long-standing denervation method without any complications in future practices based on the mechanisms of nerve degeneration as well as following regeneration.
