Background: Axillary bromhidrosis is a disease characterized by malodor caused by the interaction between apocrine gland secretions and bacteria. Current treatment modalities include topical treatment, liposuction curettage, microwave therapy, and surgical intervention. Objective: This retrospective study aimed to evaluate the clinical outcomes and quality of life over a 3-year follow-up period of the 1,444-nm Nd:YAG laser and surgical treatment for bromhidrosis. Methods: Forty-five patients participated in the study, with 20 patients receiving laser treatment and 25 patients undergoing surgery using the modified Inaba method. The degree of remaining axillary malodor, pain, reduced mobility, and overall patient satisfaction were assessed retrospectively through medical records and direct or indirect patient interviews at 7 days, 1 month, 2 months, 6 months, 1 year, and 3 years after each treatment. The modified Dermatology Life Quality Index (DLQI) was used to evaluate the quality of life. Results: Over the course of all the assessed time periods, the remaining odor and overall satisfaction scores did not differ significantly between the two groups. However, the laser-treated group reported significantly lower pain scores, reduced mobility, and total DLQI score. There were no significant differences in adverse events between the two groups. Conclusion: In our study, laser treatment for bromhidrosis showed comparable efficacy to surgery. Moreover, fewer adverse events occurred in the laser group. In addition, patient quality of life was better after laser treatment. In conclusion, subdermal coagulation treatment with the 1,444-nm Nd:YAG laser may be a less invasive and effective therapy for bromhidrosis. (Korean J Dermatol 2023;61(4):209∼216)

[연구목적] 본 연구에서는 선행연구의 도산예측모형을 바탕으로 기업도산확률과 재무건정성지수(P, Z-Score, K-Score)를 이용하여 K-IFRS의 도입 전·후에 회계정보의 유용성이 어떠한 변화가 있는지를 진단하고자 한다. [연구방법] 코스닥 기업을 대상으로 선행연구의 도산예측모형을 바탕으로 기업도산확률과 재무건정성지수(P, Z-Score, K-Score)를 이용하여 2002년부터 2010년까지의 IFRS 도입전과 2011년부터 2019년까지의 IFRS 도입 후로 구분하여 그 차이를 비교하였다. [연구결과] 도산확률이 높을수록 재량적 발생액은 증가하고, 재무건전성지수 K-Score가 증가하면 재량적 발생액은 감소하는 것으로 나타났다. 그러나 IFRS 도입 전후의 차이는 없었다. 도산확률이 증가하면 보수주의액은 증가하고, 재무건전성지수 K-Score가 증가하면, 보수주의액은 감소하는 것으로 검증되었다. K-Score에서만 보수주의액으로 한 회계이익의 질의 평가에 있어서 K-IFRS 도입 전에는 유의한 차이가 없는 것으로 나타났으나, K-IFRS 도입 후에는 차이가 있는 것으로 나타났다. [연구의 시사점] 2002년부터 2019년까지의 코스닥 기업의 자료를 활용하여 K-IFRS의 도입 전·후의 회계이익의 질을 평가하는데 있어 실증적 연구결과를 제시함에 따라 선행연구와는 차별성을 가진다 하겠다. [Purpose] This study diagnoses changes in the usefulness of accounting information before and after the introduction of the K-IFRS using the probability of corporate insolvency and financial stability indicator (P, Z-Score, K-Score) based on the bankruptcy prediction model used in previous studies. [Methodology] Prior to the introduction of the IFRS from 2002 to 2010 and from 2011 to 2019, using the corporate insolvency probability and financial stability indicator (P, Z-Score, K-Score) based on the bankruptcy prediction model used in previous studies for KOSDAQ companies. The differences are compared after the introduction of the IFRS up to 1 year. [Findings] Discretionary accruals increase as the probability of bankruptcy increases, and discretionary accruals decrease as the K-Score of the financial stability indicator increases. However, there is no difference before and after the introduction of the IFRS. As the probability of bankruptcy increases, the amount of conservatism increases, and as the KScore of the financial stability indicator increases, the amount of conservatism is verified to decrease. In the evaluation of the quality of accounting profits based on conservatism only in K-Score, there is no significant difference before the introduction of the K-IFRS, but there is a difference after the introduction of the K-IFRS. [Implications] In evaluating the quality of accounting profits before and after the introduction of the K-IFRS, using data from KOSDAQ companies from 2002 to 2019, there is differentiation from previous studies according to empirical study results.

Nevus unius lateris (NUL) is a variant of an epidermal nevus that involves a widespread body surface, especially half of the body, and its onset usually occurs at birth or early life. An increased risk of basal cell carcinoma (BCC) in epidermal nevus has also been reported. However, the exact incidence remains unknown. A 67-year-old female patient visited our dermatology clinic with black nodules protruding over multiple verrucous brownish patches and plaques on the right side of the trunk. The patient had congenital NUL. Black nodules were observed to develop several months previously and gradually enlarged. The skin biopsy of one black nodule was consistent with BCC. Subsequently, Mohs micrographic surgery was performed for the BCC. To date, there have been few reports of BCC arising within the nevus unius lateri. Herein, we report a rare case of BCC considered to originate from a congenital NUL. (Korean J Dermatol 2024;62(1):50∼52)

A Study of the traditional Korean fishing boat is based on a report on an investigation of the Korean fishing boats, conducted in 1921. The report was completed in 1927 with the conclusion of the Southern Sea region and West Sea region studies, which included the investigation of the entire region. It was a very thorough and scientific investigation of Korean fishing boats, which has been published in three volumes. Based on this report, this paper surveys the characteristics and the hull form of the traditional Korean fishing boats. As a result, we find out that the hull form of the traditional Korean fishing boat is very similar to that of modern sailing boat. Thus, it is a good candidate for the development of the modern sailing boats for the Korean Sea.

Erosive adenomatosis of the nipple (EAN) is a rare benign entity that involves abnormal proliferation of the lactiferous ducts of the nipple and often presents with visible erosive lesions, erythema, or discharge. A 34-year-old female patient visited our clinic with erythematous patches and bloody discharge from the right nipple. Ultrasonography revealed a hypervascular lesion. A punch biopsy was performed, and histopathological examination confirmed the diagnosis of EAN. A 22-year-old female patient presented with a 4-year history of itchy erythematous eczematous patches with telangiectasia, crust, and bloody discharge in the areolar region. The punch biopsy results were consistent with those of EAN. The patient underwent total excision surgery. Herein, we report cases of EAN, which were difficult to differentiate from Paget's disease or nipple eczema, highlighting the need for clinicians to pay close attention.

목적: 화농성 척추 감염은 그 범위가 광범위하여 임상 양상, 치료 및 예후를 예측하기 힘들다. 이에 단일 및 복합병소를 보이는 화농성 척추 감염 환자를 비교하여 감염의 종류, 양상, 치료 방법 및 그 효과를 분석해 보고자 하였다. 재료 및 방법: 2001년 6월부터 2006년 11월까지 화농성 척추 감염 환자 총 30명을 대상으로 하였으며, 단일병소 및 복합병소를 보이는 환자를 각각 1군, 2군으로 설정하였다. 치료 결과는 적혈구 침강속도(ESR), C-반응성 단백 (CRP) 그리고 임상 증상의 호전으로 평가하였다. 결과: 1군은 총 15예로 남자 7예, 여자 8예였다. 술전 평균 ESR/CRP는 62.7 (㎜/hr)/5.7 (㎎/dl)이었으며, 주 증상은 대부분 요통이었다. 흉요추부 및 요추부에 주로 발생하였다. 수술적 치료를 시행한 9예 중 2예에서 내고정 삽입술을 시행하였다. 2군은 총 15예로 남자 4예, 여자 11예였다. 술전 평균 ESR/CRP는 78.5 (㎜/hr)/16.7 (㎎/dl)이었으며, 주 증상은 요통 및 발열이었다. 기존 질환의 이환은 1군에 비해 많았다. 수술적 치료를 시행한 12예 중 6예에서 내고정 삽입술을 시행하였다. 결론: 병발 감염의 경우 기존질환이 있는 환자에서 호발 하였고 술전 염증 반응 수치도 높게 나타났다. 따라서 보다 신중하고 적극적인 치료가 요구 된다고 사료된다. Purpose: Pyogenic spinal infection encompasses a broad range of clinical entities, treatment and prognosis. We compared the symptoms and treatment efficacy of patients with single and combined spinal infections. Materials and Methods: Between June 2001 and November 2006, 30 patients with pyogenic spinal infections were treated in our hospital and outcomes were evaluated through ESR, CRP, and clinical improvement. Groups 1 and 2 represented patients with single lesions and patients with combined lesions, respectively. Results: Group 1 included 7 men and 8 women, and the preoperative mean ESR and CRP were 62.7 ㎜/hr and 5.7 ㎎/dl. The most common clinical presentation was back pain. Nine patients in group 1 underwent operation, and two underwent instrumentation. Group 2 included 4 men and 11 women, and the preoperative mean ESR and CRP were 78.5 ㎜/hr and 16.7 ㎎/dl. The most common clinical presentations were back pain and fever. Thirteen patients in group 2 underwent operation, and six underwent instrumentation. There were more underlying diseases in group 2. Conclusion: There were more underlying diseases and higher preoperative inflammatory-reactive laboratory findings in patients with combined spinal infections. Careful attention must be directed to treatment in order to secure favorable clinical outcomes in patients with combined infections.

갑판침수를 고려한 화학제품운반선 건현 검토에 관한 연구

박종헌(Jong-Heon Park) 한국해양공학회 2010 韓國海洋工學會誌 Vol.24 No.2

This paper deals with the problem of developing a new decision procedure for the freeboard of a coastal chemical tanker going on the coast. The decision procedure is mainly constructed with the algorithm of estimating statistically the time period that deck wetness will last on the deck of the ship. Deck wetness is one of the most important safety factors for sailing of a coaster. It generally means the situation in which the amplitude of the relative motion between the deck and the surface of the wave exceeds the freeboard. Therefore, in this paper, we proposed that the time during which the amplitude remains above the level of the freeboard should be appraised on the basis of statistical theory. A series of numerical calculations u￡re executed for four different coastal chemical tankers (199G/T Type Ⅱ, Ⅲ & 4990G/T Type Ⅱ, Ⅲ). It was demonstrated that the present decision procedure of freeboard is practical for planning the type of coaster sailing in the sea.
