The adhesive mechanisms on the metal-ceramic restorations have been reported to be mechanical interlocking, chemical bonding, compressive force, and Van der Waal's force, etc. Of these, the mechanical interlocking and chemical bonding forces are thought to affect the adhesive force between Ni-Cr alloy and porcelain. This study investigates the adhesion of Ni-Cr alloy to porcelain according to surface treatment. For this purpose, the following experiments were made; The compositions of Ni-Cr alloy as cast by emission spectrograph, and the oxides produced on Ni-Cr alloy during degassing at $1850^{\circ}F$ for 30 minutes in air and in vacuum were analyzed by X-ray diffractograph. The metal phases of Ni-Cr alloy were observed according to porcelain-baking cyclic heat treatment by photo microscope and the distribution and the shift of elements of Ni-Cr alloy and porcelain and the failure phases between Ni-Cr alloy and porcelain by scanning electron microscope. The adhesive force between Ni-Cr alloy and porcelain was measured according to surface treatment with oxidization and roughening by Instron Universal Testing Machine. Results were as follows; 1. The metal phases of Ni-Cr alloy as cast and degassing state showed the enlarged and fused core, but when subjected to porcelain-baking cyclic heat treatment, showed a dendrite growing. 2. The kinds of metal oxides produced on Ni-Cr alloy during degassing were found to be NiO and $Cr_2O_3$. 3. The distribution of elements at the interface of Ni-Cr alloy and porcelain in degassing state showed demarcation line, but in roughening state, showed mechanical interlocking phase. 4. The shift of elements at the interface occurred in both states, but the shift amount was found to be larger in roughening than in degassing. 5. The adhesive force between Ni-Cr alloy and porcelain was found to be $3.45{\pm}0.93kg/mm^2$, in degassing and $3.82{\pm}0.99kg/mm^2$, in roughening. 6. The failure phase between Ni-Cr alloy and porcelain showed the mixed type failure.

본 연구는 국민주권, 국민의 기본권, 삼권분립을 규정한 헌법의 핵심을 효력 정지시키는 비상사태(예외상태) 논리에 기반한 헌법 조항들의 역사적 형성과 그 운용의 실제에 주목했다. 구체적으로 한국전쟁기와 유신체제기에 발동한 국가긴급권을 분석 대상으로 삼고 있다. 이 글은 두 시기의 국가긴급권의 구조와 운용을 비교라는 방법을 통해 분석한다. 두 시기가 차별적인 국가긴급권의 구조와 운용 모델을 가졌다는 전제를 가지고 비교한 것이 아니라 두 시기의 연속과 차이라는 점에서 비교의 방법을 활용하고자했다. 다시 말해 본격적인 비교역사사회학 연구라기보다는 유신체제기 긴급조치권의 요소들을 계보적으로 볼 때 한국전쟁기 긴급명령권의 연속과 단절 속에서 확인했다. 이 글은 ‘예외상태 상례’의 용법 및 방법을 확립하기 위해 슈미트, 벤야민, 아감벤의 차이와 종합을 이론적으로 검토했다. 다음으로 국가긴급권이 한국 제헌헌법과 유신헌법에 기입되는 과정을 예외상태의 창출이라는 차원에서 분석했다. 제헌헌법에 긴급명령권 조항을 누가 어떻게 기입했고, 기입 과정의 논란과 조항의 내용분석을 통해 그 성격을 검토했다. 그리고 유신헌법에 긴급조치권 조항을 누가 어떻게 기입했고, 이 비상전권을 구성하는 국내외적 요소들(국가보위에 관한 특별조치법, 제헌헌법의 긴급명령권, 프랑스 ‘드골헌법’의 비상대권 등)을 분석했다. 이런 맥락에서 긴급조치 조항의 내용과 그 성격을 검토했다. 마지막으로 두 시기의 긴급명령권과 긴급조치권 발동 및 운용을 예외상태의 상례화라는 차원에서 분석했다. ‘비상사태’를 이름으로 한 최초의 법인 긴급명령 제1호의 발동 요건, 절차, 통제가능성, 그리고 운용 결과를 분석했다. 그리고 긴급조치 제1호를 실제적 예외상태가 아닌 픽션적(정치적) 예외상태의 시각에서보아 그 발동 및 운용의 결과를 역사적으로 설명했다. This study aims to explore the reality of the historical formation of constitution clues and its management based on logics of state of exception; which stop essence of constitution, defining the separation of legal, administrative, and judicial powers. In specific, this study takes main research subject as Presidential Emergency Order, aroused at two historic moments; the period of Korean War and of the Revitalizing Reforms system. This study’s focus on presidential emergency order #53, and the First Constitution #57, and analyze how it was designed implemented, operated and managed.

내가 진짜 애국자다

강성현(Kang, Sung-Hyun) 역사비평사 2015 역사비평 Vol.- No.113

The “9.23 Anti-Communist mass meeting” was held immediately after the Law on Punishment of Anti-National Activities had been enacted. But this meeting ended up with a failure of a national attempt on Pro-Japanese Punishment blaming the opponents for being communists (Red-Enemy) or Anti-Communist Propaganda. Jong-Hyoung Lee who once had been devoted into the independence movement but then became a Japanese-apologist, reporting independent activists to the authority so led them to be arrested and executed. After liberation, he fought in the front line against Pro-Japanese Punishment Act movement using both pen (newspaper) and gun (assassination).

전후 미국의 `점령형 신탁통치`의 성립과 냉전적 변형 ― 조선, 미크로네시아, 류큐제도를 중심으로

강성현 ( Kang Sung Hyun ) 한국사회사학회 2016 사회와 역사 Vol.0 No.112

본 연구는 미국의 전후 기획과 실행에서 점령과 신탁통치가 어떻게 결합되고, 이 `점령형 신탁통치`가 어떻게 냉전적으로 변형되는지 검토한다. 우선 군사점령 및 이를 통한 종속지역에 대한 지배와 통치의 역사, 그리고 국제법적 논의를 면밀히 고찰한다. 제국주의의 식민지 확장 전쟁과 점령이 국제정치 및 국제법의 틀 내에서 어떻게 견제를 받으면서 제도화되었고, 그 과정에서 만들어진 위임통치-신탁통치 `장치`를 관계적으로 살펴본다. 다음으로 조선, 미크로네시아, 류큐제도를 대상으로 분석했다. 조선은 `적국으로부터 분리된 지역`이었고, 미크로네시아는 일본의 위임통치령이었으며, 류큐제도는 일본 주권이 미치는 영토였다. 조선은 유엔에 의한 4개국(미·소·영·중)의 `비전략적 신탁통치` 적용이 시도되었다가 끝내 좌절되었고, 미크로네시아는 미국으로의 `병합`과 신탁통치 적용 사이에서 결국 미국을 유일한 시정권자로 하는 `전략적 신탁통치`로 귀결되었으며, 류큐제도는 유엔이 아닌 샌프란시스코 대일평화조약을 통해 미국을 유일한 시정권자로 하는 신탁통치로 결정되었다. 이 글은 세 지역에서 기획, 적용, 냉전적 변형을 겪은 신탁통치를 `점령형 신탁통치`의 시각에서 분석한다. This study examines how occupation and trusteeship are combined in the U.S. Post-war Plan, the plan`s implementation, and how `occupational trusteeship` transforms during the Cold War. First, this article addresses military occupation`s history of control and domination of dependent areas through an analysis of international law. I examine imperialist colonial expansion-motivated use of war and occupation, while investigating colonial institutionalization within the framework of international politics and international law via the Mandate and Trusteeship `Dispostif`.Next, I analyze Korea, Micronesia, and the Ryukyu Islands. Korea was a “territory which may be detached from enemy state”, Micronesia was a territory held under the mandate of Japan, and the Ryukyu Islands were territories falling within the sovereignity of Japan. In Korea, four countries (U.S., USSR, British, China) tried to protract a `non-strategic trusteeship` (U.S., USSR, British, China), but their attempts failed. In the case of Micronesia, between the `annexation` to the U.S. and the application of the trusteeship, it eventually resulted in a `strategic trusteeship` with the U.S. as the sole administering authority. Ryukyu Islands was placed under the U.N. International trusteeship system through a peace treaty, with the U.S. as the sole administering authority. This article analyzes the international trusteeship system that was planned, applied, and transformed in the above three locations from the viewpoint of `Occupational Trusteeship`.

항암치료제로서의 면역관문 억제제에 관한 최근 연구 동향

Immune checkpoint receptors are crucial molecules for adjusting immune responses. Checkpoint signaling dampens T cell activation to avoid autoimmunity and the destructive effects of an excessive inflammatory response. It is well established that tumors use several mechanisms to avoid elimination by the immune system. Checkpoint blockade therapy utilizes monoclonal antibodies to release the brakes from suppressed T cells, allowing them to be activated and recover their antitumor activity. This therapeutic approach has revolutionized cancer immunotherapy, and extraordinary increases in overall survival were noted, first with anti-CTLA-4 (cytotoxic T lymphocyte associated protein-4) and subsequently with anti-PD-l (programmed cell death receptor-I) in melanoma and other malignancies. The complex biology of immune checkpoint pathways still contains many mysteries, and the full activity spectrum of checkpoint blocking drugs is currently the subject of intense study. In this review, we discuss the discovery of immune checkpoints, the clinical application of their inhibitors and the future directions of this highly interesting class of molecules.

강성현(Kang, Sung-hyun) 역사비평사 2014 역사비평 Vol.- No.109

This study analyses and evaluates issues relating to the “reconstruction of truth” of the Sewol Ferry disaster and past events, and suggests solutions to find the basic logic and method for the “reconstruction of truth” of the disaster. This study also defines the meaning of “reconstruction of truth” based on a review of the history of past settlements and models in Korea. From this review an evaluation of issues pertinent to a “reconstruction of truth” of the Sewol Ferry disaster is made that suggests limitations and tasks that need to be done with respect to the existing special law relating to the event. The main issues reviewed are the organization, status and independency of the committee examining the disaster, participation and leadership of the victim"s advocacy, the authority of investigation, examination and prosecution, and the time of investigation.

한국전쟁 전 정치범 양산 법계열의 운용과 정치범 인식의 변화

강성현 ( Sung Hyun Kang ) 수선사학회 2010 史林 Vol.0 No.36

Once Korean War broke out, there was a huge illegal massacre done by state and the victims had been imprisoned for their political offending record or peoples in preliminary custody because of past record. Now we seek, who they were and why they had to die? The official penology terms define them as “anti-state and immoral left-wing criminal prisoner” and it suggests that this harsh treatment toward them, regarding latent inner enemy in state, was `inevitable` resolution for security of the rear. How this `anti-state` and `immoral` became one compositive phrase like synonyms? Following general semantics, `anti-state` complies with `aberzeugungsverbrechen` bearing religious or political motif of commitment. And `immoral` complies with `heinous criminal` implying inhumane charge-murder, rape. In spite of that, the then judicial authorities were using this compositive phrase, `anti-state and immoral` without any matter, and what made it possible? This issue is to define the historical formation of this compositive phrase, “anti-state and immoral` itself. In other words, we daringly retrace track of `political prisoners; becoming heinous criminal as a whole` in Korean history. And what does `left-wing criminal prisoner` mean accurately? `Left-wing criminal prisoner` might be `betrayers, `red rebel`, `National Security Law violator` or, for general use of this concept, `rebellious element`. However, no one of these terms can clarify their identity. If so, were they strong `holder` of leftism throughout their ideology, thought and activity? Or do they include many `collaborators` throughout those anti-state camp? Rather than above all, this term is neither definable nor fixed one-it is so intangible, insubstantial that `anyone` can be the one of it and the power holder of that time can put a brand on `someone`. And this indeterminacy of the term has a potential. At this point, we see this `branding` was a result of specific judicial procedure. For example, `Proclamation No.2 violator` and `National security law`s violator` shows by its own naming, these criminal were arrested for their `violating` commitment against `the existing public order`. If it is so, now we need to seek what `the existing public order` contains mainly and why they were-what sort of commitment had been legal basis of the `violation` at that time. It is, in truth, this work has to be excavation not only legal statues, also actual applications and managements of the law at that time. From above, to retrace a truth beyond this huge illegal butchery driven by its own state, an identity of the `anti-state and immoral` `left-wing prisoner` is equal work to research laws which had been manufacturing the political prisoners at the period from United States Army Military Government in Korea to Korean government establishment. This work also do examination of `law species`, a certain group of legal articles, making someone into political prisoner regardless his or her individual political faith or motif and of when, how and why those political prisoner became heinous criminal. This paper firstly tries to analyze `law species` which was a mechanism of manufacturing political prisoner-Proclamation No.2 during U.S Military Government in Korea. Also it investigates the establishment and the application of National Security Law after government`s establishment to pursuit facts of the historical formation and transition of political prisoner cognition. With this, this paper covers following related topics during these two period; the conflicting political prisoner cognition and debate throughout various social groups, the transition of political prisoner`s meaning, how this political prisoner cognition drives that massacre to political prisoners in jail just after outburst of war.
