PURPOSE: The purpose of this study was to identify trends in intervention studies on childhood obesity in Korea. METHODS: From 1996, when the first research paper on childhood obesity intervention was published, to 2015, 192 published papers were analyzed using descriptive statistics. RESULTS: The number of studies increased sharply between 1996 and 2007, but declined slightly from then. The majority of studies involved only children as intervention participants. Most were elementary students, and overweight and obese children. Exercise therapy was the most common type of intervention. Parental participation was found in 35 studies, while teacher's participation was found in only one study. In many studies physiological indicators were used as measurement variables, but follow-up was done in only 10 studies. Finally, only a few studies applied a conceptual framework, while a quasi-experimental research design was used for most studies. CONCLUSION: Examination of trends in intervention studies on childhood obesity in Korea, shows there has been a quantitative increase but not enough improvement in terms of the quality of interventions. Findings in the present study suggest that it is necessary to seek diversity in terms of study participants, interventions and evaluation method along with quality improvement in research methodology.

Repetitive transcranial magnetic stimulation (rTMS) is widely recognized as an effective and noninvasive neuromodulation for treating depression, and has been applied in a wide range of clinical settings. However, previous studies often reported inconsistent antidepressant effects that may be due to differences in the rTMS protocols such as coil placement. The typical simulation site for rTMS depression protocol is the left dorsolateral prefrontal cortex (DLPFC). Targeting the exact site of the left DLPFC while considering individual brain structure has been challenging due to the non-invasive nature of rTMS. Several researchers have applied various targeting methods to overcome the abovementioned issue. Most of the previous studies have applied the “5-cm rule” or the “international 10-20 system,” which is easily applicable. Recently, researchers started to apply a neuronavigation system that targets the stimulation site based on neuroimaging of each individual. Pros and cons of targeting methods have been discussed in terms of validity and reliability of targeting stimulation sites, differences in treatment responses, as well as considerations of individual characteristics. Therefore, the current review focuses on the targeting methods of stimulation site and the treatment effects of depression in previous studies. For discussion, we divided neuronavigation methods into using fixed coordinates and using individualized targets. Furthermore, the limitations of each targeting method are discussed that may potentially contribute to the development of the optimal rTMS protocol for depression treatment.

PURPOSE: The objective of this study was to examine the effect of the body shape discordance, the difference between true body type based on body mass index (BMI) and self-recognized body image, on nutrient intake, weight control attempt, and mental health in Korean adults. METHODS: Subjects were persons aged 19~64 years (4,382 men and 6,226 women) who participated in the 2010~2012 Korea National Health and Nutrition Examination Survey. Subjects were categorized as RL (Group recognized as lighter than BMI criteria), RA (Group with agreement between BMI criteria and self-recognized body image), and RH (Group recognized as heavier than BMI criteria) according to the difference between actual body type based on BMI and self-recognized body image. RESULTS: Means of BMI in RH groups were lower than or equal to that of RA groups in all groups. No significant differences in total energy intake were observed among the three groups in men, but total energy intake was higher in the RL group than in the RH group in 30~49 year old women. Proportion of carbohydrate was the highest in the RL group among 30~49 year old women. RH groups paid more attention to weight control and had less weight gain than other groups. Higher proportions of depressive symptoms were reported in the RH group in 19~29 year old men, while a higher proportion of depressive symptoms were reported in the RL group in 50~64 year old men. CONCLUSION: The current findings suggest an association of perceiving body shape with energy intake, weight control attempt, or depressed mood in some age groups. Body image perception can influence eating, weight control attempt, and depressed mood, therefore proper body image perception should be established in Korean adults.

PURPOSE: This study examined and compared the associations of the iron status and food intake with the blood lead, mercury, and cadmium concentrations among Korean adolescent girls, premenopausal women, and postmenopausal women. METHODS: The data from the 2010~2011 Korea National Health and Nutrition Examination Survey (KNHANES) was used. The subjects were classified into three groups: adolescent girls (n = 268), premenopausal women (n = 1,157), and postmenopausal women (n = 446). The iron status was assessed by hemoglobin, hematocrit, serum ferritin, and iron concentrations, as well as the total iron binding capacity (TIBC). The food intake was estimated by a food frequency questionnaire. RESULTS: The blood heavy metal concentrations and poisoning rate in postmenopausal women were higher than in the other groups. The iron status in the adolescent girls and postmenopausal women was higher than that in the premenopausal women. In the adolescent girls, the iron status was inversely associated with the blood cadmium concentration. The dairy food intake was inversely related to the blood lead and cadmium concentrations. In premenopausal women, the iron status was inversely associated with the cadmium concentrations. The fish and shellfish food intakes were positively associated with the mercury concentrations. In postmenopausal women, the iron status was positively associated with the mercury and cadmium concentrations. Fast foods and fried foods were inversely associated with the lead concentration. CONCLUSION: The premenopausal women showed a lower iron status than the adolescent girls and postmenopausal women. The associations of the iron status with the blood heavy metal concentrations were different among the adolescent girls, premenopausal women, and postmenopausal women. In addition, the relationships of the food intakes with the blood heavy metal concentrations differed among adolescent girls, premenopausal women, and postmenopausal women. Further studies will be needed to confirm these findings.

The proton magnetic resonance spectroscopy (¹H-MRS) is a tool used to detect concentrations of brain metabolites such as N-acetyl aspartate, choline, creatine, glutamate, and gamma-amino butyric acid (GABA). It has been widely used because it does not require additional devices other than the conventional magnetic resonance scanner and coils. Demyelination, or the neuronal damage due to loss of myelin sheath, is one of the common pathologic processes in many diseases including multiple sclerosis, leukodystrophy, encephalomyelitis, and other forms of autoimmune diseases. Rodent models mimicking human demyelinating diseases have been induced by using virus (e.g., Theiler's murine encephalomyelitis virus) or toxins (e.g., cuprizon or lysophosphatidyl choline). This review is an overview of the MRS findings on brain metabolites in demyelination with a specific focus on rodent models.

Aggression and aggressive behaviors, often explained as harmful social interaction with the intention of hurting or inflicting damage upon another, have been considered as an adaptive mechanism from the evolutionary psychological point of view. However, various studies on aggression and aggressive behaviors have been done with psychopathological approach as the extreme aggressive behaviors may harm themselves and others at the same time. Recently, researchers have attempted to explain aggression in terms of neurobiological substrates rather than based on traditional psychopathological and/or behavioral concept. In this regard, there have been findings of differences in neurotransmitters and their receptors, and genetic polymorphisms. In this review article, we provide a brief overview of the literature about seven most frequently reported neurotransmitters including neurohormones (serotonin, norepinephrine, dopamine, gamma-aminobutyric acid, nitric oxide, oxytocin and vasopressin) and an associated enzyme (monoamine oxidase A), which are known to be related with aggression and aggressive behaviors.

Criminology has been understood within a sociological framework until the emergence of neurocriminology, which describes, understands and predicts criminal behaviors from a neurobiological point of view. Not only using biological factors including genes and hormones to understand criminal behaviors, but also using neuroimaging techniques, the field of neurocriminology aims to delve into both structural and functional differences in the brain of individuals with aggression, antisocial personalities, and even the criminals. Various studies have been conducted based on this idea, however, there still are limitations for the knowledge from these studies to be used in the court. In this review article, we provide an overview of the various research in neurocriminology, and provide insight into the future direction and implication of the field.

OBJECTIVES: Firefighters and rescue workers are likely to be exposed to a variety of traumatic events; as such, they are vulnerable to the risk of post-traumatic stress disorder (PTSD). The psychometric properties of the Korean version of the PTSD Checklist (PCL), a widely used self-report screening tool for PTSD, were assessed in South Korean firefighters and rescue workers. METHODS: Data were collected via self-report questionnaires and semi-structured clinical interviews administered to 221 firefighters. Internal consistency, item-total correlation, one-week test-retest reliability, convergent validity, and divergent validity were examined. Content validity of the PCL was evaluated using factor analysis and receiver operating characteristic (ROC) analyses were used to estimate the optimal cutoff point and area under the curve. RESULTS: The PCL demonstrated excellent internal consistency (alpha = 0.97), item-total correlation (r = 0.72-0.88), test-retest reliability (r = 0.95), and convergent and divergent validity. The total score of PCL was positively correlated with the number of traumatic events experienced (p < 0.001). Factor analysis revealed two theoretically congruent factors: re-experience/avoidance and numbing/hyperarousal. The optimal cutoff was 45 and the area under the ROC curve was 0.97. CONCLUSIONS: The Korean version of the PCL may be a useful PTSD screening instrument for firefighters and rescue workers, further maximizing opportunities for accurate PTSD diagnosis and treatment.

Shift workers experience a disruption in the circadian sleep-wake rhythm, which brings upon adverse health effects such as fatigue, insomnia and decreased sleep quality. Moreover, shift work has deleterious effects on both work productivity and safety. In this review, we present a brief overview of the current literature on the consequences of shift work, especially focusing on attention-associated cognitive decline and related behavioral changes. We searched two electronic databases, PubMed and RISS, using key search terms related to cognitive domains, deleterious effects, and shift work. Twenty studies were eligible for the final review. The consequences of shift work can be classified into the following three categories extracted from the literature review : 1) work accidents ; 2) commuting accidents such as car accidents that occur on the way to and from work ; and 3) attendance management at work (i.e., absenteeism, tardiness, and unscheduled early departure). These cognitive and behavioral consequences of shift work were also found to be associated with sleep disorders in shift workers. Thus, improvements in the shift work system are necessary in order to enhance workers' health conditions, work productivity, and safety.
