This study conducted a comparative analysis of benthic macroinvertebrate communities in the Fosu and Benya lagoons in Ghana, based on the anthropogenic effect on the two lagoons. Salinity, oxygen, temperature, conductivity, turbidity and pH were measured, invertebrate richness and species densities were determined. The AZTI Marine Biotic Index (AMBI) and multivariate statistics were used to determine the different responses of fauna to pollution. The fauna were categorized into five ecological groups based on the degree of tolerance of the different species to pollution: disturbance-sensitive species; disturbance-indifferent species, disturbance-tolerant species, second-order opportunistic species; and first-order opportunistic species. The Fosu Lagoon supported more pollution tolerant species, whereas the Benya Lagoon had more species that were sensitive to organic enrichment under relatively unpolluted conditions. Chironomus sp., which is adapted to virtually anoxic conditions, was the most abundant in the Fosu Lagoon whereas Nemertea sp. was the most abundant in the Benya Lagoon. The numerical and relative abundance (%) of all 7 taxa in the Fosu Lagoon was 1,359 and 92.35%, respectively. The numerical and relative abundance (%) of all 34 taxa in the Benya Lagoon was 2,459 and 87.52%, respectively. Expectedly, the level of dissolved oxygen in the less saline Fosu Lagoon was higher than that in the more saline Benya Lagoon. The reduced photoperiod and photosynthetic activities of aquatic plants might account for this trend. There is a need to implement comprehensive monitoring and management initiatives for sustaining the ecological health of coastal lagoons in Ghana in order to support the many people that depend upon these ecosystems for their livelihood.

Carbon Neutral is one of the magnifying pan-governmental tasks which aim for stabilizing pan-global ecosystem. The purpose of this study is to estimates carbon neutral degree in cities by using capacity of carbon storage, which is carbon sinks, on forest and to develop an indicator that could be utilized in establishing policy related to climate change respond. When the carbon emitted from city has been absorbed or stored, the value of the indicator aiming to achieve carbon neutral could be drawn. The result and implication are as follows. First, while the annual amount of carbon emission in Gyeonggi S city was 18,787 thousand (tons), which was the highest, that of Gyeongbuk U city indicated the lowest with approximately 112 thousand (tons). Second, Gyeongbuk U city represented the largest capacity of annual carbon storage with about 16,748 thousand (tons), whereas the smallest figure was shown in Gyeonggi B city with 151 thousand (tons). Third, as result of the estimation of carbon neutral degree, the value of the indicator in Gyeonggi B city was 3% referring the lowest point, while that of other cities demonstrated over 100%. Forth, it has the possibility to suggest the fixed quantity when the plan for achieving carbon neutral of city is being processed. In the near future, after the completion of the construction projects of greenhouse gas inventory in all local governments, by utilizing the relative dates, the value of the indicator can be calculated and a more general conclusion could be drawn. Moreover, as expanding case studies to all domestic cities, generalness is in need.

Background: The phenomenon of tree dieback in forest ecosystems around the world, which is known to be associated with high temperatures that occur simultaneously with drought, has received much attention. Korea is experiencing a rapid rise in temperature relative to other regions. Particularly in the growth of evergreen conifers, temperature increases in winter and spring can have great influence. In recent years, there have been reports of group dieback of Pinus densiflora trees in Korea, and many studies are being conducted to identify the causes. However, research on techniques to diagnose and monitor drought stress in forest ecosystems on local and regional scales has been lacking. Results: In this study, we developed and evaluated an index to identify drought and high-temperature vulnerability in Pinus densiflora forests. We found the Drought Stress Index (DSI) that we developed to be effective in generally assessing the drought-reactive physiology of trees. During 2001-2016, in Korea, we refined the index and produced DSI data from a 1 × 1-km unit grid spanning the entire country. We found that the DSI data correlated with the event data of Pinus densiflora mass dieback compiled in this study. The average DSI value at times of occurrence of Pinus densiflora group dieback was 0.6, which was notably higher than during times of nonoccurrence. Conclusions: Our combination of the Standard Precipitation Index and growing degree days evolved and short- and long-term effects into a new index by which we found meaningful results using dieback event data. Topographical and biological factors and climate data should be considered to improve the DSI. This study serves as the first step in developing an even more robust index to monitor the vulnerability of forest ecosystems in Korea.

Objectives : The purpose of this study was to examine the effects of Auricular acupressure with semen sinapis in obese children over a specific period of time. Methods : The study subjects included 27 obese children who were evaluated as such using Broca's Index at an elementary school located in M city. The data was collected throughout March 2, to May 31, 2005. In order to collect data, as a pre-test, characteristics of obesity and general characteristics were examined. Experimental treatments were used on Shinmun, Kijeom, Wijeom, Bijeom and Naebunbijeom. Among the auricular spots, one pill of semen sinapis was placed and pressed for five seconds at a time with exerted force and the subjects endured pain. This procedure was conducted ten tunes every morning, noon and evening for a period of six weeks. As a post-test, the degree of obesity were examined two weeks, four weeks and six weeks after acupressure had been applied. The data was collected and analysed using the SPSS/WIN 10.0 program by number, percentage, mean standard deviation, and Repeated Measure ANOVA. Result : The first hypothesis that 'The obesity of the children who had auricular acupressure with semen sinapis will show no difference over time' (two weeks, four weeks and six weeks after acupressure had been applied) was rejected(p=.000). A statistically significant difference in the obesity of the children who had auricular acupressure with semen sinapis was shown over time. The children's obesity degree reduced from 35.85% before auricular acupressure with semen sinapis to 28.67% six weeks after acupressure. Thus after six weeks of acupressure the relative degrees of obesity were reduced by 7.18%. Conclusion : Bases on the above results, it can be determined that auricular acupressure with semen sinapis can be used as an effective method of treatment in Korea, for reducing degrees of obesity in children.

The main purpose of this study was to find the relationship between the delinquency-onset time in the source and the continuity of delinquency. In order to achieve this objective, we divided 350 first-year high school students into three groups early-onset type, late-onset type, and non-delinquent adolescents on the basis of the delinquency onset. The results of this study were as follow: (1) for the boys, the early-onset type shows a higher continuity of delinquency than both the late-onset type and the general adolescents. On the other hand, for the girls, the early-onset type shows a higher continuity of delinquency than the late-onset type, but there was no difference in the persistence duration between the late-onset type and the non-delinquent adolescents. (2) For the boys, the examination reveals that the early-onset type has a higher degree of sensation seeking and impulsivity than the general adolescents. In addition, the early-onset type shows a higher degree of sensation seeking than the late-onset type, whereas the two show no difference in impulsivity. For the girls, sensation seeking did not show any difference depending on the delinquency onset. However, more impulsivity appeared in the early-onset type than in the late-onset type or the non-delinquent adolescents. (3) The relative priorities of variables determining the group to which the students belong on the basis of the delinquency onset are in the order of sensation seeking and juvenile impulsivity. Therefore, this study, suggests that the early-onset type requires a different kind of intervention than the late-onset type.

Objectives: Insufficient evidence exists regarding factors that affect screening adherence among people with a family history of diabetes, who comprise roughly half of all patients with diabetes. Therefore, we aimed to identify the determinants of diabetes screening adherence in adults with a family history of diabetes who had not yet been diagnosed with diabetes. Methods: This cross-sectional study was conducted at selected urban primary healthcare facilities in Tehran, Iran. The study population was clinically non-diabetic adults above 20 years of age with a family history of diabetes in at least 1 first-degree relative. All eligible people identified on randomly-selected days of the month were invited to join the study. Results: Among 408 participants, 128 (31.4%) had received a fasting blood glucose check during the last year. Using binary logistic regression, the independent predictors of screening adherence were knowledge of adverse effects of diabetes such as sexual disorders (odds ratio [OR], 3.05) and renal failure (OR, 2.73), the impact of family members' advice on receiving diabetes screening (OR, 2.03), recommendation from a healthcare provider to have a fasting blood glucose check (OR, 2.61), and intention to have a fasting blood glucose check within the next 6 months (OR, 2.85). Other variables that predicted screening adherence were age (OR, 1.05), job (being a housekeeper; OR, 3.39), and having a college degree (OR, 3.55). Conclusions: Knowledge of the adverse effects of diabetes, physicians' and healthcare providers' advice about the benefits of early disease detection, and family members' advice were independent predictors of screening adherence.

The term hamartoma was first used by Albrecht to describe what he considered to be localized errors of development involving one or more tissue native to the organ of origin. The definition was meant to encompass not only abnormal local growth rate, but also the spatial arrangement, relative proportions and degree of the component tissue. But lately the major conclusions are that this group of lesion is neoplastic than developmental in origin. The Importance of pulmonary hamartoma is that they are relatively common among the benign tumor of the lung, but they usually present as asymptomatic coin lesion on chest x-ray film and were find out In routine check up and frequently mimic clinically the more common lung tumor such as cancer. Recently, we have experienced three cases of pulmonary hamartoma which were all discovered during routine chest film check up for certificate of health and evaluation of other disease. All of these were surgically resected with good result. Among the operations, one of these was mass enucleation and the others were lobectomy of lung involved by the mass.
