Daylight Saving Time (DST) is used worldwide and affects millions of people annually. In the most countries, DST begins turning clocks forward by an hour in the spring and backward by an hour in the fall. transition out of DST in the fall increases the available daylight in the morning by one hour. Springtime transition into DST leads to an increase of the available daylight in the evening. During World War I, in an effort to reduce fuel consumption, Germany and England began to practice DST in 1916. Currently, 77 countries and most of OECD adopted DST except Korea, Japan, Iceland. The rationale for Daylight Saving Time (DST) is bolstered by the fact that it increases daylight hours within which the activity a population reaches its peak. Therefore, the effects of transitions into DST to the public health should be further explored, as DST affects millions of people annually and its impacts are still largely unknown. A general perception is that Turning clock forwards (on spring) or backwards (on fall) by one hour would affect our health. In This study, the association between Daylight Saving Time (DST) and health in population was investigated through theoretical and systemic review studies. Since the study was conducted solely on theoretical grounds, further research is needed to assess additional health-related impacts of Daylight Saving Time (DST) and to carry out more specific analysis on population health in Korea. In conclusion, population health is more strongly affected during spring transition into DST than during fall transition out of DST.

2.Overview of Medical Examinations for Aircrew.
Korean Journal of Aerospace and Environmental Medicine 2008;18(2):33-41
Medical examinations for aircrew (MEA) have been applied in various extents since World War I, when medical fitness of aircrew began to be spotlighted as a major factor of flight safety and flight performance. The main purpose of MEA is to identify any presumptive medical defects that may cause sudden incapacitation and aircraft accident consequently. However, the value of medical screening tests has been debated for many years and raised questions of their effectiveness and aeromedical usefulness. Therefore, this review article focuses on diverse perspectives regarding MEA and tries to develop the most appropriate way of implementing medical examinations for insuring flight safety.

Korean Journal of Rehabilitation Nursing 2009;12(1):47-54
PURPOSE: This paper was to review the concept of rehabilitation sports for the disabled. METHOD: This paper was reviewed related papers published by KODDI(Korea Disabled People's Development Institute) concerning rehabilitation sports. RESULT: Rehabilitation sports that is integration of rehabilitation therapy and sports, was introduced in the U.K. during the World War I for the people wounded in the war. Since then, it was introduced into Germany for the wounded and disabled, and institutionalized in public health insurance program since 1960s. The present day, rehabilitation sports in Germany has been affected on promotion of physical, psychological, and social function and is being considered an importance field of sports and rehabilitation therapy for the disabled. Now, in our country, research is being carried out to introduce rehabilitation sports for the people with disabilities.

5.Health risks related to shift work among female workers of major manufacturing industries in Korea.
Korean Journal of Preventive Medicine 1991;24(3):279-286
Much of the working population in developing countries are engaged in shift work now and the number of shift workers is not expected to decrease in the future mostly because the need for continuity of production is increasing. Therefore, the possible effects of shift work on health are of particular interest, and in fact, there have been many epidemiological studies on shift work since the first world war. However, no studies on health effects of shift work have been reported in Korea, and the existing studies in western world have arrived at quite different conclusions mainly because the conditions of work other than shift work, such as age and selection of workers, work environment, and labor conditions also influence the health of workers. This study was firstly carried out in Korea to investigate the health risks related to shift work with 2,093 female workers randomly selected from three major manufacturing industries in proportion to total number of female workers in those industries. Differences of work conditions other than shift work in this study were adjusted by multivariate analysis. Major findings obtained from this study are as follows: 1. There were significant differences between shift and day workers in the distribution of age, type of industry, condition of noise and dust, regularity of mealtime, working position, and working duration. Shift workers tended to be younger, to have shorter working duration, to have more irregular mealtime, to work in standing position, and to work under more noisy and dusty environment than day workers. 2. Univariate analysis showed that shift work increased the Todai Health Index (THI) scores of digestive tract, respiratory tract, and mental instability symptom categories. Shift work also increased days of sickness absence and number of industrial accident per 100 workers per month. 3. Multivariate analysis that adjusted the differences of demographic, occupational and non-occupational health-related working conditions showed that digestive tract symptoms and mental instability symptom scores were significantly higher in shift workers than those in day workers. Based on those study results, it is concluded that the shift work has significant effects on some psychophysiological conditions of the workers and the effects are also influenced by several other personal and working conditions.

Korean Journal of Medicine 2010;78(5):540-551
Modern medical oncology has introduced various anti-cancer drugs since the World War I and II. Unlike for the solid tumors, hematological malignancies had been documented some limitations for curing it with chemotherapeutic agents only. In 1960, Dr. Nowell and Dr. Hungerford had discovered elongated chromosome (Philadelphia chromosome) which has documented as a product of translocation between 9th and 22nd chromosome in the patients with chronic myeloid leukemia. In 1970s, immunochemistry technique using monoclonal antibody has spread world widely and from 1990s, flow cytometry method has been available. In appreciation of these evolutions in basic science, the treatment strategy ofhematological malignancies has changed from the chemotherapeutic agents to targeted agents. Among the targeted agents, some drugs are newly developed and others are recreated as anti-cancer drugs after long-time of discard because of their toxicities or teratogenic effects. Nowadays, we are in the middle of flood of targeted agents, for example, tyrosinekinase inhibitors, epidermal growth factor receptor blockers, farnesyl transferase inhibitors, histone deacetylase inhibitors, and etc. In 21st century, the optimal treatment of hematological malignancies should follow a tailor- made strategy according to the patient and disease itself. In the present article, some representative agents will be introduced in accordance with target diseases.

7.Scientizing Everyday Life, Rationalizing Eating Habits: The Rise of Nutrition Science in 1910s-1920s Japan.
Korean Journal of Medical History 2018;27(3):447-484
Historians of science have noted that modern nation-states and capitalism necessitated the systematic creation and implementation of a wide array of knowledge and technologies to produce a more productive and robust population. Commonly labeled as biopolitical practices in Foucauldian sense, such endeavors have often been discussed in the realms of public hygiene, housing, birth control, and child mortality, among others. This article is an attempt to extend the scope of the discussion by exploring a relatively understudied domain of nutrition science as a critical case of social engineering and intervention, specifically during and after World War I in the case of Japan. Research and dissemination of knowledge on food and health in Japan, like other industrializing nation-states, centered on new public hygiene initiatives since the late nineteenth-century. However, in the aftermath of WWI, or more precisely, after the Rice Riots of 1918, a new trend began to dominate the discourse of nutrition and health. In the face of wartime inflation and the resultant nation-wide riots, physicians and social scientists alike began to view the food choice and budget issue as a solution to the middle class crisis. This new perception drew on the conceptual framework to understand food, metabolism, and cost in the language of quantifiable nutrition vis-à-vis monetary values. By analyzing how specific nutritional knowledge was translated into the tenets for public campaigns to reform everyday life, this paper ultimately sheds light on the institutionalization of a new area of research, nutrition (eiyō) in Japan.

8.The Necessity for a Trauma Surgeon and the Trauma Surgeon's Role in the Trauma Care System.
Journal of the Korean Society of Traumatology 2008;21(1):1-7
When man first walked on this planet, injury must have been a close encounter of the first kind. The outbreak of World War I, during a period of rapid scientific growth in the basic sciences, demonstrated the need to develop better methods of care for the wounded, methods that were later applicable to the civilian population. Trauma is a multisystem disease and, as such, benefits from almost any advance in medical science. As we learn more about the physiology and the biochemistry of various organ systems, we can provide better management for trauma victims. Improved imaging techniques, better appreciation of physiologic tolerance, and increased understanding of the side effects of specific surgical procedures have combined to reduce operative intervention as a component of trauma patient care. On the other hand, because of this rapid development of medical science, only a few doctors still have the ability to treat multisystem injuries because almost doctor has his or her specialty, which means a doctor tends to see only patients with diagnoses in the doctor's specialty. Trauma Surgeons are physicians who have completed the typical general surgery residency and who usually continue with a one to two year fellowship leading to additional board certification in Surgical Critical Care. It is important to note that trauma surgeons do not need to do all kinds of operations, such as neurosurgery and orthopedic surgery. Trauma surgeons are not only a surgeon but also general medical practitioners who are very good at critical care and coordination of patient. In order to achieve the best patient outcomes, trauma surgeons should be involved in prehospital Emergency Medical Services, the Trauma Resuscitation Room, the Operating Room, the Surgical Intensive Care and Trauma Unit, the Trauma Ward, the Rehabilitation Department, and the Trauma Outpatient Clinic. In conclusion, according to worldwide experience and research, the trauma surgeon is the key factor in the trauma care system, so the trauma surgeon should receive strong support to accomplish his or her role successfully.
