Output power of photovoltaic (PV) modules installed outdoors decreases every year due to environmental conditions such as temperature, humidity, and ultraviolet irradiations. In order to promote the installation of PV modules, the reliability must be guaranteed. One of the important factors affecting reliability is intermetallic compounds (IMC) layer formed in ribbon solder joint. For this reason, various studies on soldering properties between the ribbon and cell have been performed to solve the reliability deterioration caused by excessive growth of the IMC layer. However, the IMC layer of the PV module interconnected by multi-wires has been studied less than using the ribbon. It is necessary to study soldering characteristics of the multi-wire module for improvement of its reliability. In this study, we analyzed the growth of IMC layer of the PV module with multi-wire and the degradation of output power through damp-heat test. The fabricated modules were exposed to damp-heat conditions (85 ºC and 85 % relative humidity) for 1000 hours and the output powers of the modules before and after the damp-heat test were measured. Then, the process of dissolving ethylene vinyl acetate (EVA) as an encapsulant of the modules was performed to observe the IMC layer. The growth of IMC layer was evaluated using OM and FE-SEM for cross-sectional analysis and EDS for elemental mapping. Based on these results, we investigated the correlation between the IMC layer and output power of modules.

Object : This paper is designed to inquire into the influence of eating habits on the emotion of modem people. Method : The methodology is used that searches for materials such as books and treatises on the relationship between eating habits and emotion. Result : Meat used for fast food comes from cows that are fed the feed containing growth hormone and antibiotic. Growth hormone extremely supplements fire or yang within the body while antibiotics undermines the process of yin, leading to an accumulation of damp-heat and inflammation of ministerial fire. Additives contained in instant foods also impinge on the process of yin, leading to poor digestion, damp-heat toxins and ministerial fire. Excessive consumption of meat results in incomplete combustion of fat and hinders the formation of essence. Subsequently, ministerial fire becomes hyperactive as a result of the lack of yin energy. Increased meat consumption in the human diet is coupled with unhealthy eating pattern in which people eat too much for dinner and too quickly. Eating too much disturbs digestion, making it slow and incomplete, leading to excess damp-heat conditions, insufficient amount of vital essence and eventually hyperactive ministerial fire. Milk is considered a catalyst of faster growth, making it suitable for calves. Milk intake rapidly increases the balance of yang and eventually cause hyperactivity of ministerial fire. Conclusion : It is estimated that the eating habits of modern people cause the process of yang, making them feel restless, impatient and aggressive.

To guarantee life time more than 20 years for manufacturer without stopping photovoltaic(PV) system, it is really important to test the module in realistic time and condition compared to outside weather. In here, we tested PV modules in highly stressed condition compared to IEC standards. In IEC 61215 and IEC 61646 standards, damp-heat, thermal cycle(TC200) and mechanical test are main test items for evaluating long-term durability of PV module in controlled temperature and humidity condition. So in this paper, we have lengthened the test time for TC200 and damp-heat test and increased the loading stress on surface of module. Through this test, we can get some clue of proper the method for measuring realistic life cycle of PV modules and suggested the minimum time for PV test method. The detail description is specified as the following paper.

Objective: This study reports on a treatment case of Soojeom-san plus Jeungmiyijin-tang (SJJI) on gastroesophageal reflux disease with hiatal hernia. Method: We considered a male patient suffering from gastroesophageal reflux disease with hiatal hernia because of blood stasis and damp-heat of the spleen and stomach pattern and prescribed SJJI. The progress was evaluated using the frequency scale for the symptoms of gastroesophageal reflux disease (FSSG) score, and the visual analogue scale for abdominal pain, sore stomach, and other symptoms. Results: The patient's symptoms, which included abdominal pain, sore stomach, dyspepsia, anorexia, insomnia, etc., almost disappeared. Conclusion: SJJI can be used for patients who have a chronic condition of gastroesophageal reflux disease with hiatal hernia because of blood stasis and a pattern of damp-heat of the spleen and stomach.

This is a study of two admissional patients whose chief compiaints were yellow color and itching, and fatigue. Diagnosis and treatment was based on overall analysis of symptoms from the point of view of Jaudice due to damp-geat from an Oriental Medical point of view. Injinolyungsangami was administered against Jaudice due to damp-heat and showed desirable effect on more rapid recovery of total bilirubin than previous reports about treating jaudice. Improvement was observed. For lack of objective criteria to evaluate improvement of these symptoms more case studies of this kind, done with screening tests and proper treatment through clinical application of the thinking of Oriental Medicine, will be needed.

To analyze the phenomenon of corrosion in the PV module, we experimented damp heat test at $85^{\circ}C$/85% relative humidity(RH) and $65^{\circ}C$/85% RH for 2,000 hours, respectively. We used 30 mini-modules designed of 6inch one cell. Despite of 2,000 hours test, measured $P_{max}$ is not reached failure which is defined less than 80% compared to initial $P_{max}$. Therefore, we calculate proper curve fitting over 2,000 hours. Data less than 80% $P_{max}$ is found and B10 lifetime is calculated by the number of failure specimens and weibull distribution. Using B10 lifetime that the point of failure rate 10% and Peck's model, the predictable equation of lifetime was derived under temperature and humidity condition.

This study was conducted to determine clutch size and habitat usage of Kentish plovers (Charadrius alexandrinus) breeding on Sinja-do lslet in the Nakdong Estuary from 22 April to 12 July in 1995 and from 21 April to 20 June in 1996. The Kentish plover preferred grasslands and damp sands to dry dunes as nesting sites. The difference in hatching success among these microhabitats was attributed to high tides, which washed away many nests on damp sands, and strong winds, which frequently shifted the sand to bury eggs on dry dunes. The main mortality factor in grasslands was predation by magpies Pica pica. Each clutch contained one to four eggs, with a mode of three eggs. Hatching success was highest in two-egg clutches and lowest in one- and four-egg clutches. The mean interval for egg laying was 1.8 days between the first and second eggs and 2.1 days between the second and third eggs. The average incubation period was about 24.2 days.

As the cholera was spread over the Joseon dynasty at 1821, Hwang Doyeon investigated the symptoms like diarrhea, vomiting, muscle cramp and so on, and he presented the cause of cholera as the damage of Primordial-gi caused by abnormal climate and Damp-heat made by taking inadequate foods. He regarded as of great importance the ordinary health condition by guessing the prognosis of the disease, and proposed how to make a diagnosis of dehydration by observing nails and toenails. To treat cholera, he presented the methods of Sipseon-bloodletting and Singwol-moxacautery, and mentioned compound herb remedies and single herbs like garlic etc. He wrote down Mulberry leaves and Argyi wormwood leaves as the preventor of cholera to emphasize the importance of prevention, and mentioned food contraindication in addition to keep from getting worse.
