The main issue of the Q-matrix theory for cognition diagnosis is how to find the reduced Q-matrix containing the all efficient items. In this paper, based on the attribute structure matrix transformation, a novel recognition function for an efficient item vector is proposed. Two fast algorithms, transformation algorithm and expansion algorithm for finding the reduced Q-matrix are proposed as well. Some important properties are also discussed.

We always use projection transformation to display and draw 3D object. With the aid of matrix transformation algorithm, this paper deduces projection transformation matrix of 3D object’s three views, gets these points’planar coordinate, then we can present the three views. It has practical application value.

Undang-Undang Dasar Negara Republik Indonesia 1945 (UUD 1945) Pasal 24C ayat (6) menentukan bahwa hukum acara serta ketentuan lainnya tentang Mahkamah Konstitusi diatur dengan undang-undang. Berdasarkan ketentuan tersebut jelas bahwa hukum cara Mahkamah Konstitusi diatur dengan undang-undang. Makna frasa "diatur dengan" menurut Undang-Undang Nomor 12 Tahun 2011 tentang Pembentukan Peraturan Perundang-undangan materi muatan itu harus diatur hanya di dalam Peraturan Perundang-undangan yang didelegasikan dan tidak boleh didelegasikan lebih lanjut ke Peraturan Perundang-undangan yang lebih rendah (subdelegasi). Pokok permasalahan yang penting diteliti adalah apa implikasi hukum pengaturan hukum acara Mahkamah Konstitusi dalam bentuk Peraturan Mahkamah Konstitusi. Sesuai dengan permasalahan yang diangkat, penelitian ini adalah penelitian doktrinal atau juga disebut sebagai penelitian normatif. Pendekatan yang digunakan adalah pendekatan teoretis (theoretical approach), dan pendekatan konseptual (conceptual approach). Implikasi hukum pengaturan hukum acara Mahkamah Konstitusi dalam bentuk Peraturan Mahkamah Konstitusi berdasarkan hasil penelitian ini teridentifikasi ada 3 (tiga), yaitu: ketidakpastian hukum, pelanggaran hierarki peraturan perundang-undangan, dan ketiadaan tertib hukum. Akibat ketiga implikasi hukum tersebut maka penyelenggaraan wewenang dan kewajiban Mahkamah Konstitusi menjadi tidak sah. Namun demikian mengingat asas kemanfaatan dan asas praduga rechtsmatig maka selama memberi mandat dan sampai dengan belum ada pembatalan Peraturan Mahkamah Konstitusi maka tindakan MK selalu harus dianggap benar.1945 Constitution (UUD 1945) Article 24C Paragraph (6) provides that the procedural law and other provisions concerning the Constitutional Court shall be regulated by act. Based on these provisions it is clear that the law of the way the Constitutional Court is regulated by act. The meaning of the phrase "governed by" pursuant to Act No. 12 of 2011 concerning the Establishment of the Acts and Regulations on the contents of the content shall be regulated only in the delegated Legislation and shall not be further delegated to the lower Legislation Regulations (subdelegations ). The main issue that is important to examine is what is the legal implication of regulation of procedural law of the Constitutional Court in the form of Constitutional Court Regulation not in an Act. In accordance with the issues raised, this study is a doctrinal research or also referred to as normative research. The approaches are theoretical approach, and the conceptual approach. The legal implications of the procedural law setting of the Constitutional Court in the form of Constitutional Court Regulation based on the results of this study are identified there are 3 (three), namely: legal uncertainty, violation of legal hierarchy of regulations, and absence of orderly law. As a result of these three legal implications, the legal consequences for the implementation of the authority and duties of the Constitutional Court become invalid. However, considering the principle of expediency and presupposition principle of rechtsmatig then as long as giving benefit and until there is no cancellation of the Constitutional Court Regulation, the action of the Constitutional Court must always be considered true.

In this paper, an improved polytomous item relational structure theory based on Q-matrix theory is proposed, using Tatsuoka’s Q-matrix theory, we can construct the test with all efficient items which are fitting in with the given relational structure of cognitive attributes, and then, before the test, using Liu’s before-test item ordering theory, an ideal relational structural graph of itemscan be constructed, and the real efficient items can be obtained accordingly. After testing the students, an after-test structure of items can be estimated by using the Liu’s polytomous item relational structure theory. Furthermore, using Liu’s criterion related validity index, we can evaluate the estimated item relational structure of the test, and the results could be useful for cognitive diagnosis and remedial instruction.

In 1969, the language philosopher John R. Searle published his book “Speech Acts: An Essay in the Philosophy of Language,” wherein he developed the theory of speech acts of John L. Austin into a more normative direction. Though the philosophy of language is not the main issue of this article, Searle spoke out, for the first time, on a fundamental distinction between two different kinds of rules, namely constitutive and regulative rules. Actually, since that time the distinction between these two different types of rules has become fairly common in legal theory, but not in criminal procedure law or in the theory of procedure law. Only sporadically have German legal scholars gone into this distinction. This is astonishing with regard to criminal procedure law in particular because, even before 1969, some scholars had construed procedural rules as rules of a game. In doing so, they addressed an important characteristic of constitutive rules, namely the expression of the conditions of a certain result. However, the construction of procedural norms as rules of a game is imprecise because not all procedural norms actually work in this way. This becomes clear when one transfers Searle's distinction to criminal procedure law.
