Due to the major role played by several species of Streptococcus in the etiology of periodontitis, it is important to assess the pattern of Streptococcus pathogenic pathways within the infected subgingival pockets using a bacterial specific 16S rRNA fragment. From the total of 50 patients with periodontitis included in the study, only 23 Streptococcal isolates were considered for further analyses, in which their 16S rRNA fragments were amplified and sequenced. Then, a comprehensive phylogenetic tree was constructed and in silico prediction was performed for the observed Streptococcal species. The phylogenetic analysis of the subgingival Streptococcal species revealed a high discrimination power of the 16S rRNA fragment to accurately identify three groups of Streptococcus on the species level, including S. salivarius (14 isolates), S. anginosus (5 isolates), and S. gordonii (4 isolates). The employment of state-of-art in silico tools indicated that each Streptococcal species group was characterized with particular transcription factors that bound exclusively with a different 16S rRNA-based secondary structure. In conclusion, the observed data of the present study provided in-depth insights into the mechanism of each Streptococcal species in its pathogenesis, which differ in each observed group, according to the differences in the 16S rRNA secondary structure it takes, and the consequent binding with its corresponding transcription factors. This study paves the way for further interventions of the in silico prediction, with the main conventional in vitro microbiota identification to present an interesting insight in terms of the gene expression pattern and the signaling pathway that each pathogenic species follows in the infected subgingival site.

The purpose of this research is to identify the characteristics of the positive and negative expressions about residential common life between the elderly and the young and present the direction on Homeshare. In-depth interviews were conducted from Feb. to May 2016 to identify the experiences of residential common life with 10 elderly and 11 young. The result is as follows. First, Homeshare dwelling was classified into five themes of human being, residential environment, life, management and emotion. Homeshare unlike ordinary dwelling centered on blood relatives, is characteristic to involve the management that connects between the elderly and young. Second, both the elderly and young were analyzed to be positive about the residential common life. It was shown that the elderly are most positive about human being, whereas young are positive about management and residential environment. The elderly is positive to mutual exchange with the young and young's independent life but the young is positive to factors that support comfortable personal life. Third, negative expression was shown a generation gap between the elderly and the young. The elderly recognized to be negative that young people has lived freely without consideration for the elderly. In order to solve these factors, it is necessary to make improvements through arranging rules for living. Fourth, three themes, human being, residential environment and life, analyzed to be the most important factors to sustain residential common life of Homeshare. The link between management and 3 themes leads to an expansion of positive emotion, which is structurally stable and is expected to increase the sustainability of the residential common life on Homeshare.

Background and objective: Understanding abstract art as an art form requires depth of thought. Moreover, understanding land art as abstract art is challenging, given its focus on the minimalism and abstract concepts. Much focus, research, and work were actively conducted in the 1970s, as it represented an abstract expression of minimalism. The characteristics of minimalism connote abstract meanings in the use of materials. Nevertheless, the original research of works or artists has often been mentioned, but few studies have analyzed the abstract language of land art materials. The aim of this study is to thus determine the abstract meanings of materials in land art from the 1970s to the 2010s. Methods: Art-based research was employed to address the aim. This study classified the land art materials into intangible and tangible materials, where intangible materials focused on lines, circles, and labyrinths, and tangible materials focused on the earth, stones, wood, and snow. Results: Intangible and tangible materials of land art conveyed various abstract meanings. Intangible materials were reflective of connection and symbiosis with nature, delivering abstract languages of 'take-nothing,' 'reflection' and 'opportunity.' Tangible materials reflected the abstract concepts of 'intervention,' 'resistance,' 'unliving,' and 'change,' and conveyed caveats. In other words, taken together, intangible and tangible materials were presented in symbiosis-and with caveats-and delivered messages for the present and the future. Interestingly, intangible materials inherently reflect symbiosis and communicate caveats in works based on a non-contextualized present and future. Conclusion: Interpretation of the abstract languages derived from intangible and tangible materials could imply a symbiosis between humans and nature, while conveying the message that caveats, to humans, are still ongoing. This relationship plays a significant role in an artist's selection of a medium, which is reflective of abstract beliefs reflected in contemporary, nature-based works created on Earth.

Objectives: To examine effect of Korean medical treatment on patients with insomnia and correlations among changes in psychological scales before and after treatment. Methods: Medical records of 38 patients diagnosed with insomnia based on DSM-V who received Korean medical treatment (herbal-medication, acupuncture, Korean psychotherapy) for at least 8 weeks were retrospectively reviewed. Psychological scales including Insomnia Severity Scale (ISI), Beck Depression Inventory-II (BDI-II), State-Trait Anxiety Inventory (STAI), Beck Anxiety Inventory (BAI), and State-Trait Anger Expression Inventory (STAXI) were measured every four weeks and analyzed. Results: After eight weeks of treatment, ISI, BDI-II, BAI, STAI-X-1/2, and STAXI-S/T showed statistically significant decreases. Psychological scale pairs that showed a statistically significant correlation were ISI and BDI-IIㆍSTAI-X-1ㆍSTAI-X-2ㆍTA, BDI-II and BAIㆍSTAI-X-1ㆍSTAI-X-2ㆍAX-I, BAI and STAI-X-1ㆍSTAI-X-2ㆍSAㆍTA, STAI-X-1 and STAI-X-2, SA and TA, and TA and AX-I. In women, the improvement of AX-C was high. The improvement in AX-I score was significant when the disease duration was more than one year. A lower pretreatment BAI value predicted a greater decrease in ISI score after treatment. Conclusions: Korean medical treatment including herbal medicine, acupuncture, and Korean psychotherapy was effective in improving insomnia symptoms and accompanying symptoms such as depression, anxiety, and anger. In the future, more in-depth follow-up research is needed on the mechanisms by which various psychological problems (depression, anxiety, anger, etc) cause and worsen insomnia and the psychological symptoms secondary to insomnia.

<센과 치히로의 행방불명(千と千尋の神隠し)>은 미야자키 하야오(Hayao Miyazaki, 宮崎駿)의 대표작이자 세계적인 수작이지만, 작품의 본질적 측면에 대한 연구는 충분히 이루어지지 않은 미지의 텍스트이기도 하다. 기존의 연구는 이 작품에 나타나는 음식과 식사의 의미를 간과했고 이로 인해 작품의 중요한 특질을 간과하고 있다. 이에 음식의 기능을 중심으로 해당 텍스트를 분석하고, 식사의 의미를 심도 있게 논의하는 연구가 요구되지 않을 수 없다. <센과 치히로의 행방불명(千と千尋の神隠し)에서 음식은 욕망의 직접적인 표현물이다. 과대하게 섭취하려는 식욕은 욕망의 과다한 팽창을 의미하며, 이러한 팽창은 개인의 문제를 넘어 사회적 문제까지 보여 주는 징후가 된다. 따라서 음식에 대한 절도를 지켜, 내면의 욕망을 다스리는 법을 깨닫는 일은 이 작품이 궁극적으로 지향하는 가치를 시사한다고 하겠다.

Purpose: This study explored the experiences of pregnant women with depressed mood participating in a group cognitive behavioral therapy (CBT) program using video communication, based on Beck's cognitive theory. Methods: The participants were six pregnant women out of 13 women who had participated in an 8-session group CBT program using video communication for women with depressed mood (Edinburgh Postnatal Depression score of ≥9). Data were collected from February 20 through March 25, 2021. In-depth individual interviews were conducted through a video conferencing platform at 1 month post-baseline. Thematic analysis was done. Results: Three themes, 10 subthemes, and 38 concepts were derived from experiences of participating in the 4-week group CBT program (twice a week). The first theme, entitled "continuing realization" had subthemes of "a negative and instable self," "a selfish judgment that excludes others," and "a strong belief in self-control." The second theme, entitled "attempt to change for restoration" had subthemes of "shift to rational thinking," "freedom from suppressed beliefs," "tolerance of other people," and "courage for self-expression." The third theme, entitled "departure for a positive life," had subthemes of "emotional healing," "faith in oneself," and "reestablishing the criteria for happiness." Conclusion: Pregnant women with depressed mood expressed that continuing realizations and attempts to change supported their transition toward a positive direction of healing. Thus, they were able to change their distorted thinking into rational thinking through CBT using video communication. These findings support the use of group CBT using video communication with pregnant women who have depressed mood.

Purpose: Periodontal diseases are inflammatory conditions that alter the host's response to microbial pathogens. Type 2 diabetes mellitus (T2DM) is a complex disease that affects the incidence and severity of periodontal diseases. This study investigated the gingival crevicular fluid (GCF) levels of colony-stimulating factor-1 (CSF-1) and interleukin-34 (IL-34) in patients with stage III grade C periodontitis (SIII-GC-P) and stage III grade C periodontitis with uncontrolled type 2 diabetes (SIII-GC-PD). Methods: In total, 72 individuals, including 24 periodontally healthy (PH), 24 SIII-GC-P, and 24 SIII-GC-PD patients, were recruited for this study. Periodontitis patients (stage III) had interdental attachment loss (AL) of 5 mm or more, probing depth (PD) of 6 mm or more, radiographic bone loss advancing to the middle or apical part of the root, and tooth loss (<5) due to periodontal disease. Radiographic bone loss in the teeth was also evaluated; grade C periodontitis was defined as a ratio of the percentage of root bone loss to age greater than 1.0. The plaque index (PI), gingival index (GI), presence of bleeding on probing (BOP), PD, and clinical AL were used for clinical periodontal assessments. GCF samples were obtained and analyzed using an enzyme-linked immunosorbent assay. Results: All clinical parameters-PD, AL, GI, BOP, and PI-were significantly higher in the SIII-GC-PD group than in the PH and SIII-GC-P groups for both the full mouth and each sampling site (P<0.05). The total IL-34 and CSF-1 levels were significantly higher in the SIII-GC-PD group than in the PH and SIII-GC-P groups (P<0.05), and there were significant differences between the periodontitis groups (P<0.05). Conclusions: These findings suggest that IL-34 and CSF-1 expression increases in patients with SIII-GC-PD. CSF-1 was associated with the inflammatory status of periodontal tissues and T2DM, while IL-34 was associated only with T2DM.

본 연구는 정서중심심리코칭 경험의 본질이 무엇이며, 그 경험이 연구 참여자들에게 어떤 변화를 가져왔는지를 탐색하는 것을 목적으로 한다. 이를 위해 정서중심코칭을 5회 경험한 4인의 연구참여자를 대상으로 심층면접을 수행하였다. 면담자료는 Colaizzi의 현상학적 연구방법을 사용하여 분석하였다. 정서중심심리코칭은 Greenberg의 정서중심치료를 기반으로 ICF의 코칭 핵심역량과 함께 융합하여 정서를 중심으로 접근하는 새로운 코칭심리 모델이다. 분석결과, 정서중심코칭 경험 이전에는 자신의 정서를 회피하거나 억압한 면이 있었고, 이로 인해 행동에서도 효과적인 대인관계나 대안을 탐색하지 못하게 되는 결과를 보여주었다. 반면 경험 이후에는 정서에 대한 인식, 정서 조율, 정서 표현, 상대에 대한 정서 이해(공감) 등이 적응적인 형태로 발전하였으며, 효율적인 대안을 마련하게 된 것을 알 수 있었다.
