        ‘NP1+A着+NP2的A’ 구문 연구

        李阿衡 ( Lee¸ Ahyoung ) 중국어문학회 2021 中國語文學誌 Vol.- No.76

        As seen above, the phrase ‘NP1+A着+NP2的A’ was first used as a poetic permission in the lyrics of a song, and as the song gained popularity, it was widely used and settled as a phrase. If we look at the use of adjectives, in the early stages, adjectives expressing emotions suitable for the poetic acceptance used in song lyrics were mainly used, gradually, the distribution of adjectives is expanding into adjectives that express human actions and adjectives that modify things. The emotional object ‘NP2的A’ in the phrase ‘NP1+A着+NP2的A’ is a phrase that affects ‘NP1+A着’. In addition, ‘A着’ in the ‘NP1+A着+NP2的A’ syntax is a state adjective that indicates time. And the basic meaning of the phrase ‘NP1+A着+NP2的A’ is ‘the state in which NP1 is also A due to the influence of A on NP2’, which is used when NP1 and NP2 are different. In this case, the meaning of the syntax emphasizes the synchronization of A, and ‘A着’ indicates the state after the change. And NP1, the affected, acts as an affected but not passive, but actively affected subject, and in this sentence, the focus is on NP1. Next, when NP1 and NP2 become the same, it means that NP1 is in A state due to A of NP1, so it is a phrase that emphasizes the state in which NP1 is A due to overlapping meaning. The focus in this sentence is on NP2, and the qualifying adjective is often used. And as this phrase is settled, various sentences in which adjectives or NP2 are transformed are appearing.

        A Case of Withdrawal Psychosis from Internet Addiction Disorder

        Ahyoung Paik,Daeyoung Oh,Daeho Kim 대한신경정신의학회 2004 PSYCHIATRY INVESTIGATION Vol.1 No.2

        Similar to substance use disorder, patients with Internet addiction disorder (IAD) show excessive use, tolerance and withdrawal symptoms. We report a case of a patient with withdrawal psychosis who showed persecutory delusion and disorganized behaviors in addition to common withdrawal symptoms such as agitation and irritability. A 25-year-old male developed a full-blown psychotic episode within one day after discontinuing an Internet game that he had been playing for at least eight hours a day for two years. Upon admission, he had no abnormal brain imaging findings and laboratory tests. With antipsychotic medication (quetiapine up to 800 mg), his psychotic symptoms rapidly subsided and after four days of treatment, he no longer showed any signs of psychosis. This case report suggests that brief psychosis can develop during withdrawal from long-term excessive use of an Internet and the central pathology beneath the IAD is more likely a form of addiction than impulse control.

        Brevibacillus antibioticus sp. nov., with a broad range of antibacterial activity, isolated from soil in the Nakdong River

        Ahyoung Choi,Young Ho Nam,Kiwoon Baek,Eu Jin Chung 한국미생물학회 2019 The journal of microbiology Vol.57 No.11

        A Gram-stain-positive, aerobic, motile, and rod-shaped bacterial strain designated TGS2-1T was isolated from sediment soil in the Nakdong River, Republic of Korea. The optimal growth of strain TGS2-1T was observed at 28°C and pH 7.0 without NaCl supplementation. Strain TGS2-1T revealed antibiosis against various bacteria, including Staphylococcus aureus KCCM 4051, CCARM 3089 (methicillin resistant strains), Enterococcus faecalis KCCM 11814, Escherichia coli KCTC 2443, Candida albicans KACC 7270, and Filobasidium neoformans KCTC 7902. Phylogenetic analyses based on the 16S rRNA gene sequences indicated that strain TGS2-1T belonged to the genus Brevibacillus and shared 93.8–99.7% sequence similarity with Brevibacillus species. Whole-genome sequencing of strain TGS2-1T revealed a genome size of 6.2 Mbp and DNA G + C content of 47.0 mol%. The TGS2-1T genome shared an average nucleotide identity and digital DNA-DNA hybridization of 74.6–93.3% and 18.6–67.1%, respectively, with six related Brevibacillus genomes. The major fatty acid constituents of strain TGS2-1T were anteiso-C15:0 (62.3%) and anteiso-C17:0 (10.8%). Cells of strain TGS2-1T contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, seven unidentified aminophospholipids, and five unidentified lipids. The isoprenoid quinone detected in the strain was menaquinone-7 (MK-7). Based on data obtained from this polyphasic taxonomic study, strain TGS2-1T represents a novel species belonging to genus Brevibacillus, for which the name B. antibioticus sp. nov. is proposed. The type strain is TGS2-1T (= KCCM 90326T = NBRC 113840T = FBCC-B2501).

        Awareness and Practice of Global Cancer Prevention Dietary Guidelines among Koreans

        Ahyoung Yun,Yoonjoo Choi,Hyein Jung,Byungmi Kim 대한암예방학회 2025 Journal of cancer prevention Vol.30 No.1

        Due to rapid westernization, Korean dietary habits have emerged as significant risk factors for chronic disease and cancer. Despite this transition, Korea’s cancer prevention guidelines have remained consistent since their establishment about 18 years ago. This study aimed to investigate the degree of awareness and practice to global dietary guidelines among Korean adults and identify demographic and lifestyle factors associated with low practice. A cross-sectional survey conducted in 2023 included 4,000 adults and assessed their awareness and practice of four global recommendations: “Eat a diet rich in whole grains,” “Limit consumption of processed meat,” “Limit consumption of sugar-sweetened beverages,” and “Limit consumption of fast and other processed foods.” While more than half of the participants recognized the guidelines’ importance for cancer prevention, implementation rates remained below 40%. Furthermore, over 80% of the respondents expressed a compelling requirement for updated and tailored dietary guidelines. Younger individuals, those who were physically inactive, individuals who had not received prior nutrition education, and participants with obesity were more likely to exhibit low practice, particularly to guidelines limiting processed foods and sugary beverages intake. These findings highlight the need to revise Korea’s cancer prevention recommendations by incorporating global dietary practices and addressing the westernized eating patterns prevalent within the population. Efforts should focus on promoting these updated guidelines through targeted education and public health interventions that improve practice, especially in high-risk groups, and effectively mitigate the burden of diet-related cancers in Korea.

      • Smooth muscle tumor of uncertain malignancy potential: A case report

        ( Ahyoung Cho ),( Hye-sung Moon ) 대한산부인과학회 2018 대한산부인과학회 학술대회 Vol.104 No.-

        A 30 year old woman with history of pelviscopic myomectomy 5years ago, visited our center with abdominal bloating. The gestational 3month sized pelvic masses that had same consistency of myoma were palpable. But on outside pelvis & abdominal CT scan, three pelvic masses adhesive to bowel and uterus were observed with different heterogenecity from myoma. The ill-defined hypermetabolic masses were present in the pelvic cavity and were diagnosed as ovarian malignancy on PET-CT. The tumor markers such as CA-125, HE4 and ROMA were found to be higher with 262.2U/mL, 65.5 and 15.48%, respectively. Because of need for small wound and sophisticated repair for fertility, she underwent robotic surgery. The peritoneal masses were lined from the left with adhesion bands. The largest mass was attached to the peritoneum and the right peritoneal mass was adhered to the tenia coli and bladder peritoneum. A subserosal myoma was attached separately to the uterine lower segment and bladder. The pathology showed the pelvic mass was smooth muscle tumor of uncertain malignant potential (STUMP). The cytology of the peritoneal fluid was not malignant. We checked whether previous myomectomized specimen was related with STUMP or not. She rejected hysterectomy due to fertility. For protection of recurrence, provera is scheduled.
