The purpose of our study was to investigate whether the intrapulpal temperature during cavity preparation of enamel or dentin with Er:YAG laser still remained in range of safety for dental pulp protection when combined with appropriate water flow rate. The effect of different pulse repetition rates at the same pulse energy during ablation was evaluated as well. Caries-free, restoration-free extracted human molar teeth were prepared for the specimen and divided two experimental groups of enamel and dentin. Each group comprised 5 specimens and each of tooth specimens were embedded into a resin block each and measuring probe was placed on the irradiated pulpal walls. For experiments of dentin ablation, enamel layers were prepared to produce dentin specimen with a same dentin thickness of 2 mm. A pulse energy of Er:YAG laser was set to 300 mJ and three different pulse repetition rates of 20 Hz, 15 Hz and 10 Hz were employed. Laser beam was delivered with 3 seconds and less per application over enamel and dentin surfaces constant sized by $3\;mm{\times}2\;mm$ and water spray added during irradiation was a rate of 1.6 ml/min. Temperature change induced by Er:YAG laser irradiation was monitored and recorded While enamel was ablated, there was no significant difference of temperature related to pulse repetition rates(p=0.358) and temperature change at any pulse repetition rate was negligible. Significant statistical difference in temperature changes during cavity preparation in dentin existed among three different pulse groups(p=0.001). While temperature rise was noticeable when the dentinal wall was perforated, actual change of temperature due to Er:YAG laser irradiation was not enough to compromise safety of dental pulp when irradiation was conjugated with appropriate water spray. Conclusively, it can be said that cavity preparation on enamel or dentin with an Er:YAG laser is performed safely without pulp damage if appropriate volume of water is sprayed properly over the irradiated site.

While previous epidemiological studies on temporomandibular disorders (TMD) have been based on a given health center or population sample, no study has been performed on general population of Korea, especially concerning about treatment pattern such as clinician’s specialty involved in TMD treatment, types and amount of prescription medication and cost. This study aimed to investigate magnitude of health visits and treatment patterns for Korean patients with TMD through the computerized database of Health Insurance Review and Assessment Service (HIRAS). Inclusion criteria were all patients registered on the HIRAS database over 3 years' period from 2003 to 2005 and the medical records of patients with TMD as a main diagnosis were extracted. Information collected was as follows; distribution related to gender, age and region and type of hospital the patients visited, treatment duration, clinicians' specialty involved in treatment, cost, types of prescription medication and surgical treatment. The results of this study indicated that 0.15% of the population yearly sought TMD treatment, presenting with increase of incidence over the three years. Most of TMD patients were women (99.8%) and the biggest age group was second and third decades and decreased with age. Seoul and Kyeonggi province presented with higher incidence of TMD compared to the other regions of Korea, which seems to be related with magnitude of population. 56% of TMD patients visited primary care sector and the numbers of treatment visits was the highest in dental clinic (38.4%), followed by orthopedics (28%) and ENT (13.6%) clinics in order. Duration of prescription medication was the longest for anti-inflammatory analgesics, followed by antipsychotic drugs and muscle relaxants. Inpatient care related to TMD was primarily performed in dental hospital compared to medical hospital. Medical database of HIRAS provided comprehensive and vast information on epidemiologic characteristics and treatment patterns for patients seeking TMD treatment, which can be more reliable data to expect medical demand for TMD in condition that accurate diagnosis and standardized treatment is delivered in clinical settings.

이 글은 프랑스 공화국 표어 ‘자유, 평등, 형제애’의 세 번째 단어 ‘형제애’와 프랑스혁명기 여성의 관계를 살펴본다. 프랑스혁명기 형제애는 1789-1790년 ‘연맹제’에서 확인되듯 일차적으로 무장한 시민-병사들의 정치적 유대를 의미했다. 그러나 혁명이 불러일으킨 희망과 열정, 대립과 분열에 따라 이 형제애 공동체의 경계는 끊임없이 요동했다. 형제애 공동체는 자유와 평등을 지지하는 지상의 모든 이들로 확장될 수 있었지만 실제로는 전제정과 신분제에서 벗어난 평등한 국민, 조국을 지키기 위해 무장한 형제들을 지칭했고 자코뱅 시기에는 거짓 형제를 추방하는 급진적 자코뱅과 상퀼로트 투사들로 축소되었다. 혁명가들의 이 ‘상상된 공동체’에서 여성의 위치는 무엇이었을까? 이 글은 혁명기 여성들이 형제애의 공유와 정치적 시민권을 단일한 시각으로 바라보지 않았다는 것에 주목하고 여성들이 어떤 방식으로 형제애 공동체의 일원이 되고자 했는지 살펴본다. 많은 여성은 어머니 곧 ‘형제애의 보증인’으로서 형제애 공동체의 주변부에 머물렀으나 다른 여성들은 무장을 통해 형제애 공동체의 시민권을 얻고자 했다. 또 다른 여성들은 어머니의 역할을 확장함으로써 남성과는 다른 그러나 동등한 정치적 실천을 통해 형제애 공동체를 새롭게 정의하려 했다. This article examines the relationship between the concept of ‘fraternity,’ the third word of the French Republic slogan, ‘Liberty, equality, fraternity,’ and the role of women during the French Revolution. The concept of fraternity during the French Revolution, as can be seen in the ‘fédérations,’ primarily referred to the political ties between armed citizen-soldiers. However, the boundaries of this fraternity community were constantly fluctuating with the rising and falling hopes and passions aroused by the Revolution’s events, in addition to the resultant divisions and confrontations. The community of fraternity could theoretically expand to every individual on earth who advocated freedom and equality, but in reality, it only referred to equal individuals who were freed from despotism and from the Estate system, and who joined together as brothers in arms who sought to defend their country. During the Jacobin period, this community of fraternity was reduced to the radical Jacobins and Sans-culottes militants who expelled false brothers. However, what was the position of women in this “imagined community” of revolutionaries? This article’s analysis finds that women did not view their participation in this fraternity and their political citizenship from a single vantage point, and examines how women sought to become a part of this fraternity community. Many women remained on its periphery as mothers, or ‘guarantors of fraternity,’ but other women sought to obtain citizenship in the community by choosing to directly bear arms. Still others, by expanding their role of mothers, sought to redefine the community of fraternity by engaging in political practices which were different from those of the men, yet still equal.

이 글은 19세기 전반 프랑스의 사회주의자 페미니스트 폴린 롤랑의 삶과 사상을 살펴본다. 1830년대 전반기 생시몽주의자로서 앙팡탱의 새로운 도덕을 열렬히 수용했을 때부터 1848년 혁명기 ‘공동생산조합 연합’ 건설에 헌신하다 투옥될 때까지 그의 삶을 이끈 것은 ‘인간에 의한 인간 착취’의 종식과 남성과 여성의 완전한 평등에 대한 신념이었다. 결혼을 거부하고 홀로 세 아이를 키운 어머니로서의 지난한 삶, 노동자 공동생산조합에 대한 헌신과 비판, 유형지 알제리로부터의 귀환 중 맞이한 때 이른 사망은 19세기 사회주의와 페미니즘의 복잡성, 그 한계와 가능성을 생생하게 드러내준다. This article examines the life and thought of Pauline Roland, a French socialist feminist in the nineteenth century. From the first half of the 1830s when Roland, as a Saint-Simonian, ardently embraced the new moral precepts of Supreme Father Enfantin until the period of the 1848 Revolution when she was imprisoned in the midst of devoting herself to the establishment of the ‘Union of Workers’ Associations’, the driving force in her life was the conviction for the end of ‘exploitation of man by man’ and total equality between the sexes. Her life of extreme trials as a mother who refused marriage bringing up three children on her own, her devotion and sacrifice for the workers’ associations as well as her willingness to view them critically, her untimely death on the way home from Algeria, her place of exile, show vividly the complexity of socialism and feminism in the nineteenth century in their limits and possibilities.
