Paradental cysts characteristically develop adjacent to the cervical margin on the lateral aspect of a tooth root and result from inflammatory processes within the periodontal pocket. Standard management usually involves cyst enucleation while striving to retain the affected tooth. Recurrence rates are infrequent following complete removal of the lesion. However, intentional replantation becomes necessary in cases with anatomical constraints or accessibility issues. We present the case of a 13-year-old female patient exhibiting delayed eruption of the mandibular left second molar, attributed to a cystic lesion located on the lingual-coronal aspect of the tooth.

This study aimed to develop virtual reality (VR)-based content on surgical aseptic techniques for nursing students and evaluate its effectiveness. Methods: The content was developed following the system development life cycle, involving analysis, design, implementation, and evaluation. Experts and fourth-year nursing students validated the content for its validity and usability of the content. The study was conducted from December 2022 to April 2023. Results: The VR content was developed using Keller's ARCS motivational design model (attention, relevance, confidence, and satisfaction) as the fundamental strategy. Upon applying the VR content developed in this study, the research participants confirmed the values of the following sub-factors: confidence (3.86 out of 5), relevance (3.74 out of 5), attention (3.68 out of 5), and satisfaction (3.65 out of 5).

췌장 가성동맥류는 췌장염이나 췌장 수술과 연관되어 종종 생명을 위협하는 합병증으로 알려져 있다. 췌장 가성동맥류가 파열되면 치명적인 출혈을 유발할 수 있으며 높은 사망률과 관련이 있기 때문에 임상적 의심과 조기 진단이 환자의 임상 경과를 호전되게 할 수 있는 중요한 역할을 한다. 가성동맥류의 치료법 중 하나로 알려진 색전술은 효과적일 수 있으나, 췌장염과 관련된 가성동맥류 파열 환자의 색전술 치료 결과에 대한 국내 연구는 적다. 이에 췌장염으로 인한 가성동맥류 파열을 진단받고 색전술로 성공적으로 치료받은 환자들에 대한 증례를 보고한다.

Background: Individuals with calf muscle shortening may have decreased dynamic balance. Objects: This study aimed to investigate the effect of mobilization with movement (MWM) and myofascial release (MFR) on kinematic changes in dynamic balance in individuals with calf muscle shortening. Methods: Thirteen participants were randomly assigned to the MWM or the mobilization with movement added myofascial release (MWM-MFR) group. The MWM group received treatment with only MWM, whereas the MWM-MFR group was treated with MWM and MFR. Pre- and post-intervention passive range of motion (PROM), maximum reaching lengths, and modified star excursion balance test (MSEBT) results were compared for all participants. Wilcoxon signed-rank test and Mann-Whitney U test were used for statistical analysis. Results: The results showed significant within-group differences in ankle PROM, but no significant between-group differences. The maximum reaching length in the MWM-MFR group in the posterolateral direction was significantly different before and after the intervention (p = 0.005). This group also showed significantly reduced ankle abduction in MSEBT during the posteromedial direction section 3 (p = 0.007) and posterolateral direction section 5 (p = 0.049) compared with the MWM group. Conclusion: Combined MWM and MFR intervention improves ankle stability in the coronal plane during the posteromedial and posterolateral forward mo

총담관으로의 클립 이동은 복강경 수술의 드문 합병증이다. 저자들은 4년 전 복강경 담낭절제술과 복강경 총담관탐색술을 동시에 받은 66세 남자에서 Hem-o-lok 클립 이동으로 인한 담관 결석 1예를 문헌고찰과 함께 보고하고자 한다. 상복부 통증을 주소로 내원한 환자의 복부 전산화단층촬영에서 담관의 확장과 다량의 담관 결석 및 담관을 침범한 이물질이 의심되었다. 내시경역행담췌관조영술을 하여 다량의 담관 결석과 함께 이물질을 제거하였다. 이물질의 정체는 Hem-o-lok clip이었다. 복강경 담낭절제술과 복강경 총담관탐색술을 받은 환자가 상복부 통증을 호소한다면, 드물지만, 클립 이동에 의한 담관 결석 가능성도 염두에 두어야 한다.

누룩이 변하면 양조법은 대부분 변화한다. 누룩은 천연종의 미생물을 증식하기 때문에 제조법에 따라 미생물의 전체상뿐 아니라 그들 사이의 당화·발효력 그리고 산생성능의 조성이 변한다. 그래서 누룩의 긍정적인 변화는 다양한 양조법의 구현으로 나타나지만, 반대의 경우에는 제 한받기도 한다. 이런 관점에서 조선시대 누룩의 변화를 통해 양조법의 변화를 살펴보았다. 누룩은 늦어도 13세기에는 크게 만들어 바람이 잘 통하는 곳에 매달 거나 마루 위에서 띄웠는데(개방형 병국), 이는 이전의 온돌방에서 밀폐하여 띄운 누룩(밀폐형 누룩)에 비해 (내산성)당화력과 발효력이 증 가하여 사계절 술빚기가 가능해지고 다양한 주품이 만들어져서 화려한 가양주 문화를 꽃피우는 토대가 되었다. 17세기 이후 자본주의 맹아(가 내수공업)가 싹트면서 누룩은 점차 생산성을 위해 온돌방의 시렁에서 만들기 시작한다. 특히 금주령을 거치며 주도적인 제법으로 자리잡게 되고, 제한적인 온·습도 조절이 가능해지면서, 이전 보다 누룩 품질의 균일화와 질적 향상을 이룰 수도 있었지만 실제 누룩이 어떠했는지는 알 수 없다. 대신 효율적인 생산을 위해 누룩의 종류는 축소되고, 지역· 시기·제조자 등에 따라 질적 격차가 커져, 급수율을 높인 시장용(주막 등) 양조를 위해서는 누룩 사용량이 증가하고, 양조법은 갈수록 단순화 되었다. 누룩 제조는 사회·경제적 요인에 많은 영향을 받는다. 17세기 상품· 화폐경제의 확대과정(금주법 시대 포함)과 20세기 초 일제의 누룩과 양조법의 변화가 이를 반증한다. 그런 면에서 오늘날 전통주의 추락은 사회·경제적 요인에 의한 누룩의 후퇴가 근본적인 원인이다. 그러므로 누룩의 기초연구와 다양성 회복 그리고 질적 향상을 위한 제도적 장치 마련이 전통주 부활의 출발점이 되어야 한다.

Purpose: The purpose of this study was to understand the reality of the suffering as infertile women who are doing repeated ART (Assisted Reproductive Technology) for pregnancy and childbirth. Methods: The data were analyzed using Colaizzi’s (1978) phenomenological method. Nine women receiving repetitive ART participated in semi-structured, in-depth interviews for this study. Results: Data analysis yielded sixteen themes which were grouped into four theme clusters: ‘Being demoted to a tool only for pregnancy’, ‘Struggling for the happiness hard to get’, ‘Standing loneliness alone on a solitary island’, and ‘Ongoing yearning for recognition by pregnancy and childbirth’. Conclusion: The findings provide further understanding of complex experiences of women receiving ART who were struggling with practical, psychological, and relational issues in their everyday lives. Based on the results of this study, health professionals are urged to support those women receiving repetitive ART by providing comprehensive caring programs that employ personal, social, and psychological approaches so that they can resolve such issues.

The purpose of this study is to provide ideas for the development of bag design by analyzing the expression types and aesthetic formativeness of modern bag design using tassels and fringe given the newtro trend pursuing analog sensitivity in modern society. The methods and scope of this study are as follows. First, the related literature and internet data were reviewed in order to examine the expression types and characteristics of the bags of the West and East. Next, the definition and characteristics of tassel and fringe decoration in terms of the history of clothing were analyzed. Finally, the expression types and aesthetic formativeness of tassels and fringe were derived through the analysis of modern bag design shown in the fashion collections since 2010. The bags decorated with the tassels and fringe bring a variety of visual effects depending on the attachment position, direction and material composition, concentrating the gaze and radiating original style. In this study, the expression of tassels and fringe in modern bag design was classified into three types: surface decoration, shape variability, and object combination. Next, the aesthetic formativeness of modern bag design using tassels and fringe as decorative elements appeared through the mixture of heterogeneous materials and playfulness through imagination, exaggeration through extension of length and volume, and retro characteristics through reinterpretation of tradition. This study is expected to contribute to creative ideas of modern bag design which requires a global sense, which has been used in various cultures for a long time.

진단 및 치료의 발전에도 불구하고 췌장담도 악성 종양은 여전히 증가하고 있다. 수술적 절제는 유일한 완치를 기대할 수 있는 치료법이지만 대부분의 환자들은 초진단 시 국소 진행 또는 전이성 종양으로 확인되기 때문에 수술이 불가능한 경우가 많다. ERCP 또는 EUS 유도하 RFA와 광역학치료 등은 직접적으로 암 조직을 소작할 수 있는 국소 치료법으로 예후가 불량한 췌장담도암 환자에서 효과적인 치료법으로 기대를 모으고 있다. 아직 충분한 연구가 진행되지는 못하였지만 ERCP 유도하 ID-RFA는 악성 담도 협착에서 안정성과 유용성이 확인되었고, 추가적인 연구를 통해 장기 효과에 대한 검증이 진행되고 있다.

Background: Posterior shoulder tightness, which is a problem mainly seen in patients with shoulder impingement syndrome, disrupts the scapulohumeral rhythm between the humerus and scapulae. Objects: The aim of this study was to compare the effects of joint mobilization and stretching on shoulder muscle activity and internal rotation range of motion (ROM) of the glenohumeral joint in patients with impingement syndrome with posterior shoulder tightness. Methods: The research subjects included 22 in-patients with impingement syndrome with posterior shoulder tightness. They were randomly divided into two groups: one group (12 patients) was treated with joint mobilization and the other group (10 patients) was treated with stretching for the posterior shoulder tightness. Each treatment was performed five times a week for two weeks, and there were 15 sessions for each treatment. The ROM of the internal rotation and muscle activities of shoulder joint were evaluated pretest and posttest in each group. Electromyography data were collected from the upper, middle, and lower trapezius and serratus anterior during shoulder abduction of 90°, 120°, and 150°. Results: Both the joint mobilization and stretching groups showed significant decreases in muscle activity in the upper, middle, and lower trapezius on the posttest (p < 0.05). There was a significant difference in serratus anterior at 150° (p < 0.05), but there was no significant difference between group in post-hoc analysis (p > 0.025). The internal rotation ROM was significantly increased in the stretching group compared to that in the joint mobilization group (p < 0.025). Conclusion: This study found that both joint mobilization and stretching for posterior shoulder tightness were effective in muscle activity during arm abduction, also in order to increase internal rotation ROM of shoulder joint, stretching was effective in patients with impingement syndrome with posterior tightness.

The syntax of each chapter of 《The Analects of Confucius》 has many different interpretations over a long period of time. For example, there are many different interpretations in the parts saying “If you earn something that's not a moral, you don't leave it” and “It's good to learn without words, and what's not satisfied with learning, and the lazy teaching? What will I do?” In the mentioned phrases, “earn” means “earn from listening” and “What will I do?” means “What kinds of difficulties would there be?” This book tries to explore the real meaning of 《The Analects of Confucius》 by analyzing the mentioned sentence. There are various interpretations for 《The Analects of Confucius》 and other classical pieces. And those interpretations leave readers confused of Kongzi’s ideas. This comes as limitation of interpretation of the classics. Researches done by Yangshuda and Yangbojun combined traditional Sohak (Chinese Elementary Learning) and modern linguistics and decoded many phrases. The present writer also believes phrases in the classics can be solved by studying traditional Sohak, or characters, exegesis and phoneme in conjunction with modern linguistics theories.

Background: After a stroke, the patient may have abnormal muscle tone due to abnormal alignment. Physical therapists have used stretching, neural mobilization other methods to treat patients after stroke. In addition, joint mobilization is also used to stimulation in pathway of cervical segmental region and to normal cervical spine alignment. Objects: The purpose of this study was to determine whether Maitland cervical spine mobilization has an immediate effect on muscle tone and stiffness of upper extremity. Methods: Thirty subjects were divided into a experimental group (n1=10), a placebo group (n2=10), and a control group (n3=10). The Maitland cervical spine mobilization was applied in the supine position. Immediately after the intervention, muscle tone and stiffness of biceps brachii, brachioradialis, deltoid, and pectoralis major were measured using Myoton®PRO. In the placebo group, sham mobilization was applied to the fifth and sixth cervical vertebra, and the control group was instructed to control breathing. Results: In the experimental group, significant differences were found in muscle tone and stiffness of biceps brachii and brachioradialis in comparison with the affected side and the non-affected side before the intervention (p<.05), whereas there was no significant difference after the intervention (p>.05). Muscle tone of biceps brachii on the non-affected side and pectoralis major on the affected side was significantly decreased before and after the intervention (p<.05). The placebo and control group showed no changes on the non-affected and affected side, and no significant differences were detected before and after the intervention. All the groups revealed no significant differences in muscle tone and stiffness of upper extremity before and after the intervention. Conclusion: This study suggests that the application of Maitland cervical spine mobilization enhanced muscle tone of upper extremity on the involved side symmetrically, and influenced a decrease in muscle tone

담관내 유두상 점액 종양은 담관내에서 흔히 발견되며, 최근에는 전암성 병변으로 인식되어 왔다. 담관내 상피세포의 유듀상 성장과 점액생성 및 그로 인한 간내담관의 확장을 특징으로 한다. 수술적 절제가 악성 변화를 막기 위한 최선의 방법이다. 담관내 유두상 점액 종양에 대한 연구가 증가하고 있지만 수술이외의 치료에 대한 보고는 많지 않다. 우리는 75세 여자 환자가 우연히 담관내 유두상 점액 종양으로 진단 받고 아르곤 플라즈마 응고소작술로 성공적 치료를 받은 경우를 보고한다. 환자의 나이와 동반질환 등을 고려하여 수술 적 절제보다는 아르곤 플라즈마 응고소작술을 시행하였고, 치료 4주 후 시행한 경피 경간 담도내시경에서 잔여종양의 증거는 없었다.
