Koreans are one of the fastest growing immigrant groups in America. Adjsting to life in foreign country produces a great deal of stress. Differences in culture, language, expectation and social behavior can lead to misunderstandings. The pregnancy and delivery event is one of maturational crisis in life cycle. The purpose of this research was to understand the structure of the lived experience of pregnant women and postpartum mothers who had immigrated to the United States. The research question was "What is the structure of the experience of pregnant women and postpartal mothers?" The sample consisted of 16 women registrated at the Obstetrics and Gynecology Department of one local clinic in Hawaii. The unstructured interviews were carried out from Jnuary 5, through January, 30, 1994. They were audio-recorded and analyzed using Van Kaam's method. There are different views on the causative factors of stress. Maladjustement to the immigrant life, spousal conflicts, anxiety related to bringing up the bay and conflicts between mother-in-law and daughter-in-law are considered to be related factors. The experiences of pregnant women over the period of the pregnancy can be varied and can include change of body image, emotional and physical change. The experiences of postpartum mothers over the postpartum period can be varied and can include postpartum depression emotional irritability, fear related to bringing up the baby and disappointment with husband. Positive experiences over the period of pregnancy and postpartum were the strengthen-ing beliefs. Sources of support were, first, spouse then mother and faith. Support was also received from the physician in charge and through self-control. The nurse, by providing empathetic support, should be a person with whom they can express their feelings and share their experiences.

Objective: This qualitative study retrospectively examined the experience and psychological impact of contralateral prophylactic mastectomy (CPM) among Southern Chinese females with unilateral breast cancer history who underwent BRCA1/2 genetic testing. Limited knowledge is available on this topic especially among Asians; therefore, the aim of this study was to acquire insight from Chinese females' subjective perspectives. Methods: A total of 12 semi-structured in-depth interviews, with 11 female BRCA1/BRCA 2 mutated gene carriers and 1 non-carrier with a history of one-sided breast cancer and genetic testing performed by the Hong Kong Hereditary Breast Cancer Family Registry, who subsequently underwent CPM, were assessed using thematic analysis and a Stage Conceptual Model. Breast cancer history, procedures conducted, cosmetic satisfaction, pain, body image and sexuality issues, and cancer risk perception were discussed. Retrieval of medical records using a prospective database was also performed. Results: All participants opted for prophylaxis due to their reservations concerning the efficacy of surveillance and worries of recurrent breast cancer risk. Most participants were satisfied with the overall results and their decision. One-fourth expressed different extents of regrets. Psychological relief and decreased breast cancer risk were stated as major benefits. Spouses' reactions and support were crucial for post-surgery sexual satisfaction and long-term adjustment. Conclusions: Our findings indicate that thorough education on cancer risk and realistic expectations of surgery outcomes are crucial for positive adjustment after CPM. Appropriate genetic counseling and pre-and post-surgery psychological counseling were necessary. This study adds valuable contextual insights into the experiences of living with breast cancer fear and the importance of involving spouses when counseling these patients.

A 64-year-old female with glioblastoma multiforme (GBM) was assigned to our department for whole body PET/CT scan. She ingested 1 liter of pure water as negative oral contrast just before PET/CT examination. FDG-PET/CT images showed a very intense hypermetabolic, focal lesion in the abdominal cavity around descending colon. The SUVmax of the lesion was 17.2. But there was no abnormal lesion corresponded to the area of PET scan in the combined contrast enhanced CT scan. We suggested considering a malignant lesion due to very intense glycolytic activity. Conventional abdominal CT scan & colonoscopy were accomplished within one week after PET/CT evaluation. There was no abnormality in both examinations. We executed follow-up PET/CT evaluation after 1 month and couldn't find any abnormality around the corresponding area. So we concluded the hypermetabolism was colonic physiologic uptake. A colonic physiologic uptake is a well known cause of false positive finding. Nuclear physicians should be considered the possibility of malignancy when interpret focal colonic uptake, especially incidental finding. There are a few reports that using of negative oral contrast is able to reduce gastrointestinal physiologic uptakes. But as we can see in this case, although we used negative oral contrast, intense physiologic uptake is detected and maxSUV is able to up to 17.2. So, it is important to keep a fact in mind. Even though there is a colonic physiologic uptake in PET/CT image, it may be able to show very intense hypermetabolism regardless of using negative oral contrast.

The purpose of this study is to present basic data that can express beautiful silhouette by studying visual effect that depend on waist position of basic pants and the change of round belt width and analyzing the study of visual effect of the pattern design as well as the effect of design component. The stimuli are 21 samples: 7 variations of the location of the waistline and 3 variations of the width of the belt. The data has been obtained from 35 fashion design majors. The data has analyzed by frequency, factor analysis, anova, scheffe's test and the MCA method. The visual effects by the location of waistline and the width of belt are composed of 3 factors : horizontal direction factor, vertical direction factor and flexuosity factor. In these factors, horizontal factor is estimated by most important factor. Visual effect is positive when belt width widens as the location of waist line goes down to position of low belt. And in case the location of waist line is in the position of natural waist belt and low rise belt, belt of 3.2cm width is effective visually. The interaction effects between the location of the waistline and the width of the belt have significant differences in all factors. Factor that appears in visual effect of basic pants can be evaluated differently according to pattern of pants and characteristic of body shape. So we may receive better visual assessment if we consider the location of waist belt and width of belt in side of visual effect and image, when we produce pants giving variety to crotch depth.

목적: 근감소증에 중요한 요소인 척추 주변 근육 감소를 수치화한 총 지방 침윤율(total fat infiltration rate, TFI rate)과 골다공증성 척추 압박 골절(osteoporotic vertebral compression fracture) 및 관련 수치와의 상관 관계를 찾는 것을 목표로 하였다. 대상 및 방법: 2012년 1월부터 2016년 12월까지 요추의 압박 골절 진료를 본 환자들 중 1) 골밀도(bone mineral density, BMD) T score -2.5 g/cm² 미만으로 골다공증을 진단받고, 2) 요추 골절로 경피적 척추성형술(vertebroplasty) 또는 경피적 풍선척추성형술(kyphoplasty)을 받았으며, 3) 요추의 한 분절만 골절된 4) 1년 이상 추시한 환자 98명을 대상으로 후향적 연구를 시행하였다. TFI는 Image J 프로그램으로 자기공명영상을 분석하여 확인하였다. 이를 바탕으로 다열근(multifidus) 및 척추기립근(erector spinae)의 TFI와 골다공증 요소들과의 연관성을 분석하였다. 결과: 다열근및 척추기립근의 평균 TFI는 14.66±10.16이었다. 척추 BMD는 고관절 BMD와 통계적으로 유의한 양의 상관 관계를 보였으나 TFI와 음의 상관 관계를 보였다. 고관절 BMD는 체질량지수(body mass index)와 유의한 양의 상관 관계를 보였다. 또한 비타민 D 수치는 척추 BMD와 고관절 BMD에서 모두 양의 상관 관계를 보였으나, TFI와는 음의 상관 관계를 보였다. 결론: 근육량은 근감소증 환자뿐만 아니라 골다공증 환자의 치료에 있어서도 도움이 되므로 주의깊게 보아야 할 것이다. 또한 비타민 D를 증가시키는 것은 근육 위축의 진행을 늦출 수 있으므로 이로써 골절을 예방하는 효과를 가져올 수 있다.

Objective : Unclear mental state is one of the major factors contributing to diagnostic failure of occult skeletal trauma in patients with traumatic brain injury (TBI). The aim of this study was to evaluate the overlooked co-occurring skeletal trauma through whole body bone scan (WBBS) in TBI. Methods : A retrospective study of 547 TBI patients admitted between 2015 and 2017 was performed to investigate their cooccurring skeletal injuries detected by WBBS. The patients were divided into three groups based on the timing of suspecting skeletal trauma confirmed : 1) before WBBS (pre-WBBS); 2) after the routine WBBS (post-WBBS) with good mental state and no initial musculoskeletal complaints; and 3) after the routine WBBS with poor mental state (poor MS). The skeletal trauma detected by WBBS was classified into six skeletal categories : spine, upper and lower extremities, pelvis, chest wall, and clavicles. The skeletal injuries identified by WBBS were confirmed to be simple contusion or fractures by other imaging modalities such as X-ray or computed tomography (CT) scans. Of the six categorizations of skeletal trauma detected as hot uptake lesions in WBBS, the lesions of spine, upper and lower extremities were further statistically analyzed to calculate the incidence rates of actual fractures (AF) and actual surgery (AS) cases over the total number of hot uptake lesions in WBBS. Results : Of 547 patients with TBI, 112 patients (20.4 %) were presented with TBI alone. Four hundred and thirty-five patients with TBI had co-occurring skeletal injuries confirmed by WBBS. The incidences were as follows : chest wall (27.4%), spine (22.9%), lower extremities (20.2%), upper extremities (13.5%), pelvis (9.4%), and clavicles (6.3%). It is notable that relatively larger number of positive hot uptakes were observed in the groups of post-WBBS and poor MS. The percentage of post-WBBS group over the total hot uptake lesions in upper and lower extremities, and spines were 51.0%, 43.8%, and 41.7%, respectively, while their percentages of AS were 2.73%, 1.1%, and 0%, respectively. The percentages of poor MS group in the upper and lower extremities, and spines were 10.4%, 17.4%, and 7.8%, respectively, while their percentages of AS were 26.7%, 14.2%, and 11.1%, respectively. There was a statistical difference in the percentage of AS between the groups of post-WBBS and poor MS (p=0.000). Conclusion : WBBS is a potential diagnostic tool in understanding the skeletal conditions of patients with head injuries which may be undetected during the initial assessment.

Positron Emission Tomography(PET) is a new diagnostic method that can create functional images of the distribution of positron emitting radionuclides, which when administered intravenously in the body, makes possible anatomical and functional analysis by quantity of biochemical and physiological process. After genetic and biochemical changes in initial stage, malignant tumor undergoes functional changes before undergoing anatomical changes. So, early diagnosis of malignant tumors by functional analysis with PET can be achieved, replacing traditional anatomical analysis, such as computed tomography(CT) and magnetic resonance image(MRI), etc. Similarly, PET can identify malignant tumor without confusion with scar and fibrosis in follow up check. In the Korea Cancer Center Hospital(KCCH) from October 1997 to September 1999, clinical study was performed in 79 cases that underwent 89 times PET evaluation with [18F]-Fluorodeoxyglucose for diagnosis of oral and maxillofacial tumors, and the data was analysed by Bayesian $2{\times}2$ Classification Table. The results were as follows : Evaluation for initial diagnosis with FDG-PET (P<0.005) 1. Agreement rate or accuracy rate is 88.9%. 2. Sensitivity is 95.2%, and specificity 66.7%. 3. Positive predictive rate is 90.9%, and negative predictive rate 80.0%. 4. In consideration of tumor stage, diagnostic rate in less than stage II was 90% and in greater than stage III 100%. 5. In consideration of tumor size, diagnostic rate in less than T2 was 92.3% and in greater than T3 100%. After primary treatment, evaluation for follow up check with FDG-PET (P < 0.001) 1. Agreement rate or accuracy rate is 85.4%. 2. Sensitivity is 87.5%, and specificity 82.4%. 3. Positive predictive rate is 87.5%, and negative predictive rate 82.4%. 4. In 24 recurred cases, 6 had distant metastasis, and 5 of them were diagnosed with FDG-PET, resulting in diagnostic rate of FDG-PET of 83.3%. From the above results, Positron Emission Tomography with [18F]- Fluorodeoxyglucose appears to be more sensitive and accurate for detecting the presence of oral and maxillofacial tumors, and has various clinical applications such as early diagnosis of tumor in initial and follow up check and detection of distant metastasis.

본 연구는 Quick Ceph Image $Pro^{TM}$(ver 3.0)와 국내에서 개발되어 사용 중인 $V-Ceph^{TM}$(ver 3.5) 2 종의 비디오 이미지 예측 프로그램의 수술 후 연조직 측모의 정확성과 신뢰성에 대해서 알아보고자 시행되었다. 골격성 III급 부정교합으로 진단되어 수술 전 교정 치료를 받고. 하악골 후퇴 수술(body osteotomy 또는 SSRO)을 시행한 남녀 환자 각각 20명을 대상으로 하였다. 나이는 평균 $21.4\pm4$세이고, 수술 전 측모두부방사선계측사진은 수술 전 평균 21.1일에 수술 후 측모두부방사선계측사진은 수술 후 평균 335.7일에 촬영되었으며, 예측치와 실측치 차이를 비교하였다. 연구결과 Quick Ceph과 V-Ceph 모두 예측치와 실측치 사이에 크기와 방향에 있어서 오차가 관찰되었으며, 이러한 오차는 상순과 하순. 턱과 연관된 항목에서 크게 나타났다 (p<0.05). Quick Ceph은 A'. Ls, Li의 수평적 위치 및 각 부분에서의 연조직 두께(U1-Ls, L1-Li, Pog-Pog')의 수평거리 예측에서, V-Ceph은 하순의 수직적 위치 예측에서 오차가 컸다 (p<0.05) V-Ceph의 경우 하악골의 이동양이 증가할때 Sn의 수직적 위치, Ls의 수평적 위치 상순의 연조직 두께 (U1 -Ls)처럼 상순과 연관된 계측치에서 예측오차가 컸으며, Quick Ceph의 경우 하악골의 이동양이 증가할 때 하순의 수평위치 및 하순의 두께에서의 예측오차가 작았다 (P<0,05) 또한, 연조직의 두께에 따른 오차를 평가한 결과, Quick Ceph의 경우 상순과 하순의 두께가 두꺼울수록 각각에 관련된 연조직 예측의 오차가 컸으며 (P<0.05). V-Ceph의 경우 하순과 턱의 연조직 두께가 두꺼울수록 턱의 연조직 예측의 오차가 크게 관찰되었다 (p<0.05). 그러나 본 연구에서의 모든 예측오차 값은 3mm 이내로 계측되었으며, 이러한 오차 범주는 임상적으로 허용 가능한 수준인 것으로 생각된다.
