We are developing large arrays of X-ray microcalorimeters for applications in X-ray astronomy. X-ray microcalorimeters can detect the energy of X-rays with extremely high resolution. High-resolution Imaging spectroscopy enabled by these arrays will allow us to study the hot and energetic nature of the Universe through the detection of X-rays from astronomical objects such as neutron stars or black holes. I will introduce the state-of-the-art X-ray microcalorimeters being developed at NASA/GSFC and the future X-ray observatory missions based on microcalorimeters.

Measurements of ovarian reserve play an important role in predicting the clinical results of assisted reproductive technology (ART). The ideal markers of ovarian reserve for clinical applications should have high specificity in order to determine genuine poor responders. Basal follicle-stimulating hormone levels, antral follicle count, and serum anti-$M{\ddot{u}}llerian$ hormone (AMH) levels have been suggested as ovarian reserve tests that may fulfill this requirement, with serum AMH levels being the most promising parameter. Serum AMH levels have been suggested to be a predictor of clinical pregnancy in ART for older women, who are at a high risk for decreased ovarian response. We reviewed the prognostic significance of ovarian reserve tests for patients undergoing ART treatment, with a particular focus on the significance of serum AMH levels in patients at a high risk of poor ovarian response.

For us, any regional art exist? Almost all art events today take place mostly in Seoul. Concentrating on the reinforcement of its power, the regional art world remains isolated without any connection with the Seoul art community. It is completely closed off from the central art scene. The regional art world seems to consider that more helpful in consolidating its status. It is in real sense suffering the absence of art criticism and art media, lack of an understanding of art and backwardness of art education. Many regional artists are dreaming of moving out from their domain, aspiring to be a member of the central art world. They make an effort to assimilate into a refined, modern style of the central art circle, rather than striving to create works imbued with regionality and locality. As the artists living in the provinces, the characteristics of their district should be above all else reflected in their art. Although they are less informed about the latest trend of culture and art, their art has to be something passionately and obstinately embodying the intrinsic quality of their regions. They have to find a practical solution more positively, instead of merely complaining about the poor condition of the regional art community. There is the need to bring about a turnabout in our awareness that regional art is confined to any limit and cannot be in the center of the entire art world. What' s most significant is to dissolve factionalism and not to depend on school ties or regional networks. As a reaction against authoritarianism, regional art has to put emphasis on attaining its originality. For this, regional art should respect regional tradition, history and background and break away from an old convention of wielding power.

An Adaptive Random Testing (ART) is one of test case generation algorithms that are designed to detect common failure patterns within input domain. The ART algorithm shows better performance than that of pure Random Testing (RT). Distance-bases ART (D-ART) and Restriction Random Testing (RRT) are well known examples of ART algorithms which are reported to have good performances. But significant drawbacks are observed as quadratic runtime and non-uniform distribution of test case. They are mainly caused by a huge amount of distance computations to generate test case which are distance based method. ART through Iterative Partitioning (IP-ART) significantly reduces the amount of computation of D-ART and RRT with iterative partitioning of input domain. However, non-uniform distribution of test case still exists, which play a role of obstacle to develop a scalable algerian. In this paper we propose a new ART method which mitigates the drawback of IP-ART while achieving improved fault-detection capability. Simulation results show that the proposed one has about 9 percent of improved F-measures with respect to other algorithms.

In contemporary art, the process of appreciating art works requires the dichotomy between traditional art and New Media Art. This difference can be witnessed in the contrasting ways of appreciating art works; in traditional art, a certain physical and esthetic distance is placed between viewers and works of art, and in New Media Art, art is appreciated by active involvement and communication. In other words, this disparity is based on whether viewers physically involve themselves in the completion of the art works. Perhaps contemporary art can be better understood and appreciated if a single primary keyword takes the center place of art appreciation rather than allowing the dichotomy. Thus, a new approach is welcome, where art appreciation is not adversely affected through such divided means based on the degree of active participation. This is not some new introduction of jargon but the reinterpretation of contemplation, the key word for art appreciation in the past, as the common key word for both conventional art and New Media Art.

This study analyzed effect of the group art therapy with recall on the quality of life and emotion of the elderly with mild dementia in day care center. The study objects were the elderly from 75 to 96 years old and MMSE-K grade were 15-23 points with mild dementia in Jeollabuk-do day care center. The experimental group was treated group art therapy for 6 months, once a week, 60 minutes, total 30 times and the control group was treated none at the same duration. The study results had implications that group art therapy using recall method helped the elderly with mild dementia in day care center by actively embracing their life and expressing more stable emotion to get along their life.

Objective: The number of assisted reproductive technology (ART) clinics, ART cycles, clinical pregnancy rate (CPR), and number of newborns conceived using ART have steadily increased in South Korea. This aim of this study was to describe the status of ART in South Korea between January 1 and December 31, 2011. Methods: A localized online survey was created and sent to all available ART centers via email in 2015. Fresh embryo transfer (FET) cases were categorized depending on whether standard in vitro fertilization, intracytoplasmic sperm injection (ICSI), or half-ICSI procedures were used. Thawed embryo transfer (TET) and other related procedures were surveyed. Results: Data from 36,990 ART procedures were provided by 74 clinics. Of the 30,410 cycles in which oocytes were retrieved, a complete transfer was performed in 91.0% (n=27,683). In addition, 9,197 cycles were confirmed to be clinical pregnancies in the FET cycles, representing a pregnancy rate of 30.2% per oocyte pick-up and 33.2% per ET. The most common number of embryos transferred in the FET procedures was three (38.1%), followed by two (34.7%) and one (14.3%). Of the 8,826 TET cycles, 3,137 clinical pregnancies (31.1%) were confirmed by ultrasonography. Conclusion: While the overall clinical pregnancy rate for the TET cycles performed was lower than the rate reported in 2010 (31.1% vs. 35.4%), the overall CPR for the FET cycles was higher than in 2010 (33.2% in 2011 and 32.9% in 2010). The most common number of embryos transferred in FET cycles was three, as was the case in 2010.

Background: The presence of gross deletions in the human immunodeficiency virus nef gene ($g{\Delta}nef$) is associated with long-term nonprogression of infected patients. Here, we investigated how quickly genetic defects in the nef gene are associated with Korean Red Ginseng (KRG) intakein 10 long-term slow progressors. Methods: This study was divided into three phases over a 20-yr period; baseline, KRG intake alone, and KRG plus highly active antiretroviral therapy (ART). nef gene amplicons were obtained using reverse transcription polymerase chain reaction (PCR) and nested PCR from 10 long-term slow progressors (n = 1,396), and nested PCR from 36 control patients (n = 198), and 28 ART patients (n = 157), and these were then sequenced. The proportion of $g{\Delta}nef$, premature stop codons, and not in-frame insertion or deletion of a nucleotide was compared between three phases, control, and ART patients. Results: The proportion of defective nef genes was significantly higher in on-KRG patients (15.6%) than in baseline (5.7%), control (5.6%), on-KRG plus ART phase (7.8%), and on-ART patients (6.6%; p < 0.01). Small in-frame deletions or insertions were significantly more frequent among patients treated with KRG alone compared with controls (p < 0.01). Significantly fewer instances of genetic defects were detected in samples taken during the KRG plus ART phase (7.8%; p < 0.01). The earliest defects detected were $g{\Delta}nef$ and small in-frame deletions after 7 mo and 67 mo of KRG intake, respectively. Conclusion: KRG treatment might induce genetic defects in the nef gene. This report provides new insight into the importance of genetic defects in the pathogenesis of AIDS.

The purpose of this study was to examine the effects of group art therapy on maternal parenting stress and self-efficacy. The subjects of the study included 16 parents of elementary school students who participated in a group art therapy program offered at B Education Center, Pusan. Eight parents who wanted to receive parental education were allocated into an experimental group, While the other eight parents were regarded as the control group. Mothers in the experimental group participated in the group art therapy program which discussed parent education theories. This Program was composed of 17 sessions, performed once a week for one and a half hours. Research tools employed included parent stress test and parent self-efficacy test. The following results were obtained: Group art therapy was found to bring about a statistically significant decrease in parenting stress. Group art therapy was also found to bring about a statistically significant increase in parent self-efficacy. These results suggest that a program which integrates various parents education theories, within a group art therapy setting, can become an effective parent education tool which decreases maternal parenting stress and increases parent self efficacy.

Compared to Korea's recently expanding art distribution market, the difficulty of securing the authenticity of art is hindering the healthy development and growth of the market. In this regard, the current situation of the emotional system in the UK and France's art distribution process are examined as excellent cases in foreign countries. In the UK, there is a full autonomous appraisal system by art experts without state intervention. In France, the judiciary and the administration of art have an appraisal system for art works, so the appraisal work has reliability and objectivity. Through the above system, this study suggests measures to strengthen transparency in art trade and to break unfair practices in order to secure the authenticity of the domestic art distribution market. In addition, this study proposes the establishment of a professional appraisal system and the improvement of administrative law regulations to explore the possibility of ensuring fairness through mediation through the example of an international arbitration body.
