Through documents and archeological evidences, this thesis examines when Baekjae advanced to Jungwon. Jungwon was a key spot in where the ancient Three Kingdoms struggled against one another, and Baekjae occupied there for the first time among them. According to Samkuksagi, Jungwon was the center of the southern part of Baekjae where was the central target of conquest, after King Koi`s reign. The archeological evidences such as construction of fortresses and stylistic transitions of sepulchre specifically show the debouchment of Baekjae to Jungwon. After 4th century, the fortresses of Baekjae tended to swarm near Jungwon area, especially in Namhan River area, and Moho River area, and the eastern-southern part of Kyunggi. These evidences signify that Baekjae actively advanced to Jungwon than to other areas. The fact that the sepulchers of local clans like Mahan were dominantly constructed until 3rd to early 4th century, and the construction stopped since early 4th century is noteworthy characteristics of the sepulcher clusters in Jungwon. It can be understood that Baekjae aggressively advanced to Jungwon in early 4th century when Mahan`s sepulcher constitution declined, although the very first contact between them might had been earlier than that. Baekjae`s aggrandizement of its realm to Jungwon is noteworthy in its intensity, not only because it was geologically crucial, but also because iron, the strategically important resource of those days, could be attained in there.

표준섭취계수(SUV) PET과 영상 재구성 방법에 따라 크게 달라진다. 삼성 서울병원 핵의학과에 설치된 GE사의 Discovery MIDR와 Discovery Ste의 영상 재구성 알고리즘을 이용하여 의인화몸통팬텀 내의 심장, 간과 배경영역에서 표준섭취계수를 측정하여 실제 SUV와 비교하였다. 영상 재구성 알고리즘은 MIDR에서는 VPFX-S (TOF+PSF), QCFX-S-350 (Q.Clear+TOF+PSF), QCFX-S-50와 VPHD-S (OSEM+PSF), Ste에서는 VUE Point (OSEM)와 FORE-FBP를 사용하였다. 방사선사의 방사선 피폭을 감소시키기 위하여 소량의 ¹⁸F-FDG 선원을 물과 혼합하였다: 52.5 ml 심장에는 2.28 MBq, 1,290 ml 간에는 20.3 MBq와 9,590 ml 배경영역에는 45.7 MBq을 주입하였다. 심장에서의 표준섭취계수는 MIDR의 VPFX-S, QCFX-S-350, QCFX-S-50, VPHD-S와 Ste의 VUE Point (OSEM)와 FOR-FBP 알고리즘에서 각각 27.1, 28.0, 27.1, 26.5, 8.0와 7.4 이었으며, 기대치는 5.9이었다. 배경역역에서는 4.2, 4.1, 4.2, 4.1, 1.1와 1.2 이었으며, 기대치는 0.8이었다. 각 영역에서 표준섭취계수는 PET과 알고리즘에 따라 크게 차이가 있었지만, 심장과 배경영역의 SUV 비율은 비교적 일정하여 6개 영상 재구성 알고리즘에 대하여 6.5, 6.8, 6.5, 6.5, 7.3와 6.2 이었으며 기대치는 7.8이었다. 심장에서의 평균 신호 대 잡음비(SNR)는 각각 6개 알고리즘에 대하여 8.3, 12.8, 8.3, 8.4, 17.2와 16.6이었다. 결론적으로 PET 성능 평가는 각 영역에서의 절댓값 보다는 두 영역 사이의 SUV 비율이 적절하며, 비교적 소량의 방사능으로도 확인할 수 있는 가능성이 있다. The standard uptake values (SUVs) strongly depend on positron emission tomographs (PETs) and image reconstruction methods. Various image reconstruction algorithms in GE Discovery MIDR (DMIDR) and Discovery Ste (DSte) installed at Department of Nuclear Medicine, Seoul Samsung Medical Center were applied to measure the SUVs in an anthropomorphic torso phantom. The measured SUVs in the heart, liver, and background were compared to the actual SUVs. Applied image reconstruction algorithms were VPFX-S (TOF+PSF), QCFX-S-350 (Q.Clear+TOF+PSF), QCFX-S-50, VPHD-S (OSEM+PSF) for DMIDR, and VUE Point (OSEM) and FORE-FBP for DSte. To reduce the radiation exposure to radiation technologists, only the small amount of radiation source ¹⁸F-FDG was mixed with the distilled water: 2.28 MBq in the 52.5 ml heart, 20.3 MBq in the 1,290 ml liver and 45.7 MBq for the 9,590 ml in the background region. SUV values in the heart with the algorithms of VPFX-S, QCFX-S-350, QCFX-S-50, VPHD-S, VUE Point, and FOR-FBP were 27.1, 28.0, 27.1, 26.5, 8.0, and 7.4 with the expected SUV of 5.9, and in the background 4.2, 4.1, 4.2, 4.1, 1.1, and 1.2 with the expected SUV of 0.8, respectively. Although the SUVs in each region were different for the six reconstruction algorithms in two PET/CTs, the SUV ratios between heart and background were found to be relatively consistent; 6.5, 6.8, 6.5, 6.5, 7.3, and 6.2 for the six reconstruction algorithms with the expected ratio of 7.8, respectively. Mean SNRs (Signal to Noise Ratios) in the heart were 8.3, 12.8, 8.3, 8.4, 17.2, and 16.6, respectively. In conclusion, the performance of PETs may be checked by using with the SUV ratios between two regions and a relatively small amount of radioactivity.

경계성 인격장애 환자의 마음헤아리기치료 효과 : 중간분석에 대한 예비보고

Objectives The treatment of borderline personality disorder (BPD) in Korea has been based mainly on individual psychopharmacotherapy and psychotherapy. No quantitative study has examined the effectiveness of group psychotherapy for patients with BPD in Korea. In the present study, the mentalization-based treatment (MBT) program developed from the Anna Freud Center in London was conducted in the author’s hospital. This article presents the results of a preliminary analysis of the treatment effects of the Korean MBT for BPD. Methods The recruited subjects are patients diagnosed with BPD at Gangnam Severance Hospital. A psychological assessment was conducted at baseline and every six months during the treatment. Statistical analysis was performed using the data of 62 people at the baseline assessment, and the treatment effectiveness was analyzed with the data from 21 people who participated in the treatment group over six months. Results Borderline personality features were positively correlated with depressive symptoms, anxious attachment, avoidant attachment, and novelty seeking trait, and negatively correlated with self-directedness. After the 12-month treatment, the depressive symptoms and self-disclosure scores were improved significantly. In addition, the self-directedness, cooperativeness factor scores of the temperament and character inventory, and the self-regulation ability score of the resilience scale were also improved significantly. Conclusion This study suggests that the Korean MBT can improve depressive symptoms and induce positive changes in personality functioning. Although the number of people who continued MBT over 12 months was very small due to the high dropout rate, this study is the first quantitative study on the effects of the Korean MBT for BPD patients.
