통일 환경이 급변하고 있다. 이러한 상황에서 남북간의 이질화를 극복하고 민족의 동질성을 추구하기 위한 통일대비 노력으로써 북한의 실정을 바르게 이해하는 것은 무엇보다도 중요하다. 본 연구의 목적은 현장에 있는 교사들에게 남북한의 중학교 수학교육과정 및 교과서를 비교분석 함으로서 북한사회에 대한 이해를 돕고자 하는 데 있다. 북한을 이해하는 가장 효율적인 방법중에 하나가 그들의 교육을 이해하는 것이다. 그래서 본 연구는 북한의 중학교 수학교과서 및 교육과정, 내용체계등을 이해함으로써 통일한국을 준비하는 데 있다. 아무쪼록, 남북한의 통일 후 통합된 수학교육을 만드는데 도움이 되길 바란다. The situation of unification has been changing in the rapid speed. In this condion it is most important that we understand North Korea's current situation correctly, by overcoming the differences between South and North Korea and trying to pursuit the national homogeneity. The purpose of this thesis is to help the teachers in school to widen the knowledge and to understand the North Korean society by comparative analysis of South and North Korean junior high school's mathematics education process and text books. One of the most effective ways to understand North Korea is to understand their education. So, I wrote this thesis as a way of getting ready for the united Korea by knowing mathematics texts and their system, composition, contents of junior high school in North Korea Anyway, I hope that this study will be helpful to the integration of mathematics education after unification of North and South.

Emphasis has recently been laid on the importance of street space that constitutes urban space in stimulating and strengthening the functions of the downtown area In most urban areas, however, street space has deteriorated so much that it reveals barrenness This situation is owing not to the lack of proper understanding about the importance of street space planning, but to the paucity of accumulated study on the correlation between the spatial consciousness of man as the subject of a street space evaluation on the one hand and the constituent elements as the object of spatial formation on the other District unit planning is a social system that is concerned with developing street space It maps out ideal urban space for better urban environment It also aims to better utilize urban space in accordance with the size and complexity of a city The purpose of this thesis is to examine the correlation between urban planning control elements regulating constituent elements of street space and the structure of man's psychological evaluation of the streetscape It explores the influence of physical regulatory elements on the streetscape, thus providing basic data and guidelines for planning a better streetscape It makes a psychological analysis of different applications of controlling elements by employing a semantic differential method and a CG simulation The procedure of my research is first to choose adjectival pairs that describe street space through bibliographical study and preliminary survey, and then to select physical regulatory elements concerning district Unit planning My study also shows the influence of the design control elements of distinct unit planning on the streetscape, by experimenting with those elements by means of CG simulation It examines variables on the axis of psychological factors according to the variation of regulatory elements and the degree of the influence of those variables

Ticks are blood-sucking ectoparasites which rely on hosts, such as reptiles, birds, mammals, and even humans. They cause skin disorders directly by biting, and indirectly acting as a vector of virus, bacterial and rickettsial disease. Tick’s life cycle starts egg stage, larva stage, nymph stage, and lastly adult stage. Tick bite happens when they grade from larva stage to adult stage. Ticks fix their toothed hypostome into the skin and suck blood for 6~12days. Therefore their body becomes bigger and often misdiagnosed as a skin tumor or wart. A 85-year-old female patient visited our hospital with hyperkeratotic papule on her mid portion of chest. She had no symptoms like itching. The lesion had a verrucous, white, skin colored surface and its height was longer than its diameter(0.8cm x 0.5cm x 1.5cm). At the base, there was an erythematous patch, bleeding trace and sero-crust. We regarded this lesion as wart or squamous cell carcinoma and performed shaving biopsy. Histologic result showed a structure of suspected exo-skeleton which indicated a tick. In the exo-skeleton, there was a trace of a human tissue being sucked from the outside. Herein, we introduce a tick bite case that was misdiagnosed as a tumor-like lesion, wart.

Squamous cell carcinoma(SCC) is the second most common form of skin cancer. It is usually found on sun-exposed areas such as head, neck, lips, arms, etc. It presents as a firm, flesh-colored or erythematous, keratotic papule or plaque and it may also be ulcerative, nodular or verrucous. Metastatic SCC usually presents as well-demarcated painless nodules and may be mistaken for epidermal cyst, fibroma, lipomas or other benign conditions. It also resembles the primary SCC. Histopathologic examination is necessary to confirm the diagnosis. The hallmark of invasive SCC is the extension of atypical keratinocytes beyond the basement membrane and into the dermis. Grade of differentiation is associated with the grade of keratinization. A 77-years-old man was consulted for right 1st finger’s ulceration with bleeding during admission in hemato-oncology department. The lesion was a 1.5x1.5cm sized round ulcerative patch and it’s onset was several months ago. A punch biopsy specimen showed proliferation of atypical keratinocytes in the whole epidermis and invasion of dermis, which means SCC. In the patient’s past history, he had lung cancer with liver, bone metastasis and it’s subtype was SCC. We think that the finger’s lesion was caused by metastasis of the lung cancer.

( Hoo Min Choi ),( Sin Wook Chun ),( Suk Young Lee ),( Jong Baik Kim ),( Byung In Ro ),( Han Kyoung Cho ) 대한피부과학회 2016 대한피부과학회 학술발표대회집 Vol.68 No.2

Background: Dermatologic complaints have a great portion in patients visiting the emergency department (ED) than we thought. Objectives: The aim of this study is to quantify and characterize the patients visiting the ED of our hospital with skin complaints in recent 6 years. Methods: We performed a retrospective study of 464 patients who visited our ED in Myongji Hospital with treatment by a dermatologist from January 2010 to December 2015. Results: The mean age of patients was 41.2 years and there were more female patients (57%) than males (43%). The peak incidence occured in June (11.4%), and the lowest was in November (4%). In arrival time distribution, the peak incidence occurred in PM 18~21hour (23.7%) and the lowest incidence in AM 3~6hour (2.1%). In residence time distribution, the peak incidence occurred in less than 2 hours (73.2%), followed by in 2~4 hours 23.7%). Herpes zoster was most common complaint 31.6%), followed by urticaria/angioedema (12.9%), contact dermatitis (10.3%). 23.7%(n=110) of enrolled patients were admitted, mainly for herpes zoster (n=67, 60.9%). In admission rate, erysipelas/cellulitis was the highest (50%, 7/14), followed by herpes zoster (45.5%, 67/147). Conclusion: Though urticaria/angioedema and herpes zoster were most common in ED for skin complaints, appropriate diagnosis and management for other skin diseases is necessary.

[P221] A case of palmoplantar keratoderma presenting as multiple cutaneous horns

( Hoo Min Choi ),( Suk Young Lee ),( Jong Baik Kim ),( Sung Min Kim ),( Eun Jung Ko ),( Byung In Ro ),( Han Kyoung Cho ) 대한피부과학회 2017 대한피부과학회 학술발표대회집 Vol.69 No.1

Palmoplantar keratoderma (PPK) is a rare inherited or acquired heterogeneous group of skin conditions with chronic thick hyperkeratotic palms and soles. PPK is classified clinically as diffuse, focal and punctate type. Diffuse type shows symmetric hyperkeratosis over the whole of palms and soles. Focal type shows hyperkeratosis on localized area located on mainly pressure points. Punctate type shows multiple, small hyperkeratotic maculo-papular lesions on the whole or certain locations of both palm and sole. Histologically, it shows massive hyperkeratosis, acanthosis and often hypergranulosis. A 88-year-female patient presented with multiple hyperkeratotic cutaneous horns, papules and plaques on both palms and soles that were years ago. She had no symptoms as pruritus and pain. There are three types of PPK but this case’s clinical symptom is not included typically in any type. The biopsy specimen showed massive hyperkeratosis and acanthosis. Herein, we report a case of PPK presenting as multiple cutaneous horns of 88-year-female patient that was clinically unusual.

A case of superficial basal cell carcinoma in middle-aged woman

Basal cell carcinoma (BCC) is the most common form of skin cancer in the world. It appears most frequently in areas of the body routinely exposed to ultraviolet light. Superficial BCC is a rare sub-type of BCC and appears as an erythematous patch (often well demarcated) that resembles eczema in mostly younger patients. This cancer type preferentially develops on the upper trunk and shoulders. It is characterized by basaloid tumor cells confined to the epidermis or superficial dermis and there is a horizontal spread rather than deeper dermal involvement. An isolated patch of eczema that does not respond to treatment should raise suspicion for superficial BCC. A 56-years-old Korean woman presented with a round, solitary, erythematous patch with multiple microerosions and black spots on her left shoulder, of which the onset was unknown. It was well demarcated and 2 x 2 cm sized. The patient had no family history of skin cancer or a history of sunbathing, radiation, or arsenic exposure. 3mm punch biopsy specimen showed basaloid tumor islands budding from the basal layer of epidermis confined to upper to mid dermis. We diagnosed it as superficial BCC and consulted to department of plastic surgery for wide excision. Herein, we report a rare case of superficial BCC which appeared on the shoulder in middle-aged woman.

A case of lobulated intradermal nevus in young woman

Lobulated intradermal nevus is first reported by Cho et al. in 1998 with an unusual growth pattern and appearance in three patients, differed from previously described clinical types. It is a rare variant of melanocytic nevus characterized by the distinct clinicohistopathological findings. In all reported studies about lobulated intradermal nevus cases, the nevus clinically shows lobulation and manifests as corymbiform, raspberry-like or verrucous plaque. And most patients reported was 20 to 30 years old female. The nevus histopathologically presents as fat cell infiltration, neuroid differentiation of nevus cells and dermal fibrosis. This is regarded as a sign of regression of melanocytic nevus. A 26-year-old woman presented with a tumor on vertex. It was 10 years ago and had slowly been protruding from the skin surface. The lesion was a 1.2x1.0cm sized brown to black raspberry-shaped tumor. A shaving biopsy was done and histologic findings revealed the architecture of intradermal nevus with numerous isolated spaces filled with nevus cells. In contrast with other studies, there were no histopahological findings such as fat cell infiltration, neuroid diffentiation of nevus cells and dermal fibrosis. But in other studies, the onset was almost congenital or 30 years ago. In our case, the onset was 10 years and we think that the time was not enough to the regression of nevus cells.

[P427] A case of pretibial myxedema presented in the patient with hypothyroidism

( Hoo Min Choi ),( Suk Young Lee ),( Jong Baik Kim ),( Sung Min Kim ),( Eun Jung Ko ),( Byung In Ro ),( Han Kyoung Cho ) 대한피부과학회 2017 대한피부과학회 학술발표대회집 Vol.69 No.1

Pretibial myxedema is a form of diffuse mucinosis in which there is an accumulation of excess mucin (glycosaminoglycans) in the dermis and subcutis. It occurs mainly in patients with Graves` disease and rarely with Hashimoto thyroiditis, primary hypothyroidism. These patients characteristically have very high serum concentrations of thyroid-stimulating hormone (TSH) receptor antibodies. It occurs maily in women 40~60 years old. It is most commonly seen on the pretibial areas and is characterized by swelling, thickening, hardening of the lower legs. The involved skin may be violaceous or slightly pigmented (yellow-brown). Diagnosis is made by taking a history and finding characteristic clinical appearance of the skin lesion. Punch biopsy is rarely necessary but if done, it shows deposition of mucin throughout the dermis and subcutis. A 82-year-old woman had non-pitting nodules on both pretibial area and brownish edematous, thickened, hardened skin on from both pretibial area to dorsum of feet. She had no symptoms. She had been taking a levothyroxine 50μg tablet daily due to hypothyroidism. Her thyroid function test (TFT) showed hypothyroidism and high level of TSH receptor antibodies. Punch biopsy specimen showed markedly increased dermal mucin by Alcian blue stain. Herein, we report a case of pretibial myxedema presented in the patient with hypothyroidism.

( Hoo Min Choi ),( Sung Min Kim ),( Jong Baik Kim ),( Byung In Ro ) 대한피부과학회 2020 대한피부과학회지 Vol.58 No.2

Background: While many studies have investigated the epidemiology and clinical features of female pattern hair loss (FPHL), few of these are long-term studies. Objective: This study evaluated and compared a large cohort of long-term FPHL patients to short-term FPHL patients from other studies. Methods: A retrospective chart review was conducted at the Alopecia Clinic of the Department of Dermatology in Myongji Hospital of 982 FPHL patients during a 10-year period from March 2007 to February 2017. Results: The 3,549 alopecia patients included 2,342 (66.0%) with androgenetic alopecia (AGA) patients; among them, 982 (27.7%) had FPHL. Patients in their 30s (24.6%) were the most affected group of FPHL patients, followed by those in their 20s (21.7%), 40s (20.3%), 50s (13.8%), and teenagers (9.2%). The FPHL patients included 301 (30.5%) with a paternal familial predisposition, 136 (13.7%) with a maternal familial predisposition, and 70 (7.0%) with both familial predispositions. The FPHL patients were classified according to the Ludwig classification as type 1 (62.7%), type 2 (33.2%), or type 3 (3.9%). Abnormalities in serum total cholesterol levels and triglyceride levels were observed in 70 (14.3%) of 488 patients, and in 49 (21.2%) of 231 patients, respectively. The most common comorbid conditions were seborrheic dermatitis, followed by hypertension, hyperlipidemia, thyroid diseases, diabetes mellitus, polycystic ovarian syndrome (PCOS), and anemia. When seborrheic dermatitis is excluded, thyroid diseases and PCOS were most common in patients in their 20s and 30s. Hypertension, hyperlipidemia, and diabetes mellitus were most common in patients in their 40s. Conclusion: Compared to studies from 20∼30 years ago, the proportion of FPHL patients among total alopecia patients appeared to increase significantly. In addition, the proportion of teenage patients has also increased, likely due to early puberty. (Korean J Dermatol 2020;58(2):108∼114)
