POTENSI PEMANFAATAN LIGNOSELULOSA DARI BIOMASA KAYU KARET (Hevea brasisiliensis Muell Arg.)
Authors: Admojo Lestari , Setyawan Budi
Published: September 2018

Tanaman karet (Hevea brasiliensis) merupakan salah satu tanaman perkebunan utama yang cukup diandalkan di Indonesia. Luas areal karet di Indonesia sampai tahun 2016 mencapai 3,6 juta hektar. Tanaman karet memiliki umur ekonomis sekitar 25 - 30 tahun, sebelum akhirnya direplanting. Produksi kayu karet yang dihasilkan di akhir masa sadapnya merupakan salah satu biomassa potensial dengan kandungan lignoselulosa yang cukup tinggi. Lignoselulosa merupakan komponen polisakarida yang mengandung selulosa, hemiselulosa dan lignin yang berpotensi untuk diproses menjadi produk tertentu, seperti bioetanol, biogas, minyak berbasis biomasa (bio-oil), bioarang, hingga pemanfaatan selulosa yang berukuran nano (nanoselulosa) untuk kebutuhan industri elektronik, manufaktur dan otomotif. Lignoselulosa dari biomassa kayu karet antara lain dapat dimanfaatkan untuk menghasilkan sumber energi (bioetanol), pendukung sarana pertanian (bioarang, biopestisida, pupuk), industri obat dan makanan (vanilin, zat tambahan makanan, bahan kemasan) dan nanoselulosa. Produk berbahan dasar biomassa akan mendukung industri masa depan yang terbarukan, mudah terdegradasi dan lebih ramah lingkungan.
Analyzing Two Investments—An Instructional Case to Introduce Basic Financial Accounting Concepts
Authors: Bailey Wendy J. , Samuels Janet A.
Published: September 2018

This case introduces basic financial accounting concepts to graduate business students in an accounting orientation session (i.e., “boot camp”). Students assume they have invested in two cupcake businesses in Paris and they now want to determine which business performed best. Instructors can use this case, which provides students an opportunity to compare two businesses, to achieve several learning objectives including those related to accrual accounting (i.e., when to record transactions), the legal aspects of business (i.e., company structure, stock ownership, international accounting), and the use of estimates in financial reporting (i.e., depreciation, bad debts). This case also introduces students to the three basic financial statements (i.e., balance sheet, income statement, statement of cash flows), and the evaluation of financial results (i.e., net income versus cash flow, ratios). We have found that this simple, straightforward case helps students feel more confident when working with basic financial accounting concepts.

Authors: Klubo-Gwiezdzinska Joanna , Lange Maria , Cochran Elaine , Semple Robert K. , Gewert Cornelia , Brown Rebecca J. , Gorden Phillip
Published: September 2018

OBJECTIVE

Type B insulin resistance due to autoantibodies against the insulin receptor is characterized by diabetes refractory to massive doses of insulin, severe hypercatabolism, hyperandrogenism, and a high mortality rate. We analyzed the efficacy of combined immunosuppressive therapy in the management of this extreme form of diabetes.

RESEARCH DESIGN AND METHODS

We performed a prospective cohort study including patients with confirmed insulin receptor autoantibodies, monitored for median 72 months (25th, 75th interquartile range 25, 88), and treated with rituximab, high-dose pulsed steroids, and cyclophosphamide until remission, followed by maintenance therapy with azathioprine. Remission was defined as the amelioration of the hyperglycemia and discontinuation of insulin and/or normalization of hyperandrogenemia.

RESULTS

All data are given as median (25th, 75th interquartile range). Twenty-two patients aged 42 (25, 57) years, 86.4% women, fulfilled inclusion criteria. At baseline, fasting glucose was 307 (203, 398) mg/dL, HbA1c was 11.8% (9.7, 13.6), total testosterone (women) was 126 (57, 571) ng/dL (normal 8–60), and daily insulin requirement was 1,775 (863, 2,700) units. After 5 (4, 6.3) months, 86.4% (19 of 22) of patients achieved remission, documented by discontinuation of insulin in all patients, normal fasting glucose of 80 (76, 92) mg/dL, HbA1c of 5.5% (5.2, 6), and testosterone (women) of 28 (20, 47) ng/dL. During follow-up of 72 (25, 88) months, 13.6% (3 of 22) of patients developed disease recurrence, occurring 24 (22, 36) months after initial remission, which responded to repeated therapy. None of the patients died.

CONCLUSIONS

Combined immunosuppressive therapy has changed the natural history of this disease, from 54% mortality to a curable form of diabetes and, as such, should be recommended in patients with type B insulin resistance.

Published: September 2018

OBJECTIVE

Continuous glucose monitoring (CGM) has provided new measures of glycemic control that link to diabetes complications. This study investigated the association between the time in range (TIR) assessed by CGM and diabetic retinopathy (DR).

RESEARCH DESIGN AND METHODS

A total of 3,262 patients with type 2 diabetes were recruited. TIR was defined as the percentage of time spent within the glucose range of 3.9–10.0 mmol/L during a 24-h period. Measures of glycemic variability (GV) were assessed as well. DR was determined by using fundus photography and graded as 1) non-DR; 2) mild nonproliferative DR (NPDR); 3) moderate NPDR; or 4) vision-threatening DR (VTDR).

RESULTS

The overall prevalence of DR was 23.9% (mild NPDR 10.9%, moderate NPDR 6.1%, VTDR 6.9%). Patients with more advanced DR had significantly less TIR and higher measures of GV (all P for trend <0.01). The prevalence of DR on the basis of severity decreased with ascending TIR quartiles (all P for trend <0.001), and the severity of DR was inversely correlated with TIR quartiles (r = −0.147; P < 0.001). Multinomial logistic regression revealed significant associations between TIR and all stages of DR (mild NPDR, P = 0.018; moderate NPDR, P = 0.014; VTDR, P = 0.019) after controlling for age, sex, BMI, diabetes duration, blood pressure, lipid profile, and HbA1c. Further adjustment of GV metrics partially attenuated these associations, although the link between TIR and the presence of any DR remained significant.

CONCLUSIONS

TIR assessed by CGM is associated with DR in type 2 diabetes.

Universitarias argentinas. Desafíos para contarlas
Authors: Gómez Molla Rosario
Published: September 2018

Los trabajos que analizan, desde una perspectiva histórica, la participación de las mujeres en la universidad recurren habitualmente a una fuente estadística de gran valor: Evolución de la mujer en las profesiones liberales en Argentina (1900-1965), lanzada en 1965 por la Oficina Nacional de la Mujer. En primer lugar, nos interesa examinar las diversas fuentes estadísticas que se utilizan para analizar la población universitaria a lo largo del siglo XX. Luego, revisaremos los datos que la publicación de la Oficina Nacional de la Mujer recoge y señalaremos sus aportes y limitaciones. Por último, presentaremos el trabajo de reconstrucción de la información relativa a la población femenina de la Universidad Nacional de La Plata que hemos realizado, para el período 1905-1972.

Imágenes personales, corporalidades femeninas y repertorios visuales. Una mujer con cámara de fotos en 1930
Authors: Torricella Andrea
Published: September 2018

En este artículo se analiza un corpus de fotografías pertenecientes a una mujer que poseía una cámara de fotos y tomaba imágenes de su estadía en las sierras de Córdoba, argentina en la década de 1930. El objetivo es estudiar un caso significativo que pone al descubierto el modo en que las representaciones visuales del cuerpo femenino fueron una de las vías por las cuales se construyeron las identidades de género. La metodología consiste en hacer dialogar las representaciones de las fotos con otros repertorios visuales de la época. Como conclusiones sostenemos que las representaciones de género construidas en las fotos no son reflejos del estereotipo dominante de mujer, si no que combinan diversos repertorios, generando como resultado ciertos desplazamientos en las normatividades.
El Movimiento Nacional Justicialista: una experiencia de organización peronista en tiempos de proscripción (1967-1968)
Authors: Marcilese José Bernardo
Published: September 2018

Este artículo se propone estudiar a la dinámica interna del peronismo durante los años de la “Revolución Argentina”, a partir de la experiencia del Movimiento Nacional Justicialista, la estructura organizativa que integró a la rama política a partir de 1968. Con ese fin se analizan las relaciones internas entre las diversas facciones peronistas y la vinculación de la actividad política con los procesos sindicales. Del mismo modo, se pondera el creciente protagonismo de los sectores juveniles, entre los cuales se destaca el progresivo avance de la línea revolucionaria, y la participación activa de la rama femenina. Ciertamente, durante la etapa que se iniciar con el golpe militar diversos grupos políticos peronistas tuvieron una activa participación tendiente a reorganizar el movimiento con fines electorales

En este sentido, la investigación pretende indagar en el accionar de los diversos grupos que integraban la rama política del peronismo, particularmente en el distrito bonaerense, para lo cual se considerará en forma específica el carácter de las prácticas que configuraban su accionar y las estrategias que asumen frente al contexto adverso que representa el Onganiato.

Eigencages: Learning a Latent Space of Porous Cage Molecules
Authors: Sturluson Arni , Huynh Melanie T. , York Arthur H. P. , Simon Cory
Published: September 2018

Porous organic cage molecules harbor nano-sized cavities that can selectively adsorb gas molecules, lending them applications in separations and sensing. The geometry of the cavity strongly influences adsorptive selectivity.

For comparing cages and predicting their adsorption properties, we embed/encode the cavities of a set of 74 porous organic cage molecules into a low-dimensional, latent "cage space".

We first scan the cavity of each cage to generate a 3D image of its porosity. Leveraging the singular value decomposition, in an unsupervised manner, we then learn across all cages an approximate, lower-dimensional subspace in which the 3D cage cavity images lay. The "eigencages" are the set of characteristic 3D cage cavity images that span this lower-dimensional subspace. A latent representation/encoding of each cage then follows from expressing it as a combination of the eigencages.

We show that the learned encoding captures salient features of the cavities of porous cages and is predictive of properties of the cages that arise from cavity shape.
Methylamines as Nitrogen Precursors in Chemical Vapor Deposition of Gallium Nitride
Authors: Rönnby Karl , Buttera Sydney C. , Rouf Polla , Barry Sean , Ojamäe Lars , Pedersen Henrik
Published: September 2018

Chemical vapor deposition (CVD) is one of the most important techniques for depositing thin films of the group 13 nitrides (13-Ns), AlN, GaN, InN and their alloys, for electronic device applications. The standard CVD chemistry for 13-Ns use ammonia as the nitrogen precursor, however, this gives an inefficient CVD chemistry forcing N/13 ratios of 100/1 or more. Here we investigate the hypothesis that replacing the N-H bonds in ammonia with weaker N-C bonds in methylamines will permit better CVD chemistry, allowing lower CVD temperatures and an improved N/13 ratio. Quantum chemical computations shows that while the methylamines have a more reactive gas phase chemistry, ammonia has a more reactive surface chemistry. CVD experiments using methylamines failed to deposit a continuous film, instead micrometer sized gallium droplets were deposited. This study shows that the nitrogen surface chemistry is most likely more important to consider than the gas phase chemistry when searching for better nitrogen precursors for 13-N CVD.

Attack-tree-based Threat Modeling of Medical Implants
Authors: Siddiqi Muhammad Ali , Seepers Robert M. , Hamad Mohammad , Prevelakis Vassilis , Strydis Christos
Published: September 2018

Modern Implantable Medical Devices (IMDs) are low-power embedded systems with life-critical functionalities. Almost all of these devices are equipped with wireless- communication capabilities in order to aid in diagnosis, in updating the functional settings and firmware and so on, without any surgical procedure to perform these tasks manually. There is, thus, a rising trend towards increased connectivity of these devices. The down- side of this trend is, however, a proportional increase in the attack surface that can be exploited by a malicious entity. In effect, threat modeling of IMDs becomes ever more important. This is reflected by an increase in the number of vulnerabilities being found consistently in the IMDs available in market. This paper proposes a threat-modeling analysis based on attack trees to evaluate the security of these devices. As an example, three recent lightweight IMD security protocols from literature are analyzed using this approach to demonstrate its effectiveness in suggesting security improvements.
Detection and Correction of Malicious and Natural Faults in Cryptographic Modules
Authors: Karp Batya , Gay Maël , Keren Osnat , Polian Ilia
Published: September 2018

Today’s electronic systems must simultaneously fulfill strict requirements on security and reliability. In particular, their cryptographic modules are exposed to faults, which can be due to natural failures (e.g., radiation or electromagnetic noise) or malicious fault- injection attacks. We present an architecture based on a new class of error-detecting codes that combine robustness properties with a minimal distance. The new architecture guarantees (with some probability) the detection of faults injected by an intelligent and strategic adversary who can precisely control the disturbance. At the same time it supports automatic correction of low-multiplicity faults. To this end, we discuss an efficient technique to correct single errors while avoiding full syndrome analysis. We report experimental results obtained by physical fault injection on the SAKURA-G FPGA board.

Pelaksanaan tebang, muat dan angkut pada budidaya tebu memiliki pengaruh terhadap rendahnya rendemen di pabrik gula. Potensi kehilangan gula pada proses tebang angkut dimulai dari saat penebangan, pemuatan, pengangkutan ke pabrik, hingga antrian tebu menjelang digiling. Kegiatan pengamatan dilaksanakan di Pabrik Gula Madukismo pada tanggal 5 Februari 2017 hingga 5 Juni 2017. Kualitas pelaksanaan tebang, muat dan angkut di Wilayah Bantul dan Sleman tidak berbeda nyata kecuali pada rendemen sementara. Kualitas pelaksanaan tebang dapat dinilai dari beberapa kriteria yaitu besar penurunan brix dari kebun ke pabrik, kehilangan hasil tebu, serta efisiensi tenaga tebang. Kualitas pelaksanaan tebang, muat dan angkut pada kedua wilayah tidak berbeda nyata karena karakterisitik dan kondisi umum kebun yang tidak berbeda jauh. Tebang, muat dan angkut yang tepat dan efisien dicerminkan oleh prinsip MBS (Manis, Bersih dan Segar). Penerapan prinsip MBS dapat mencegah penurunan rendemen pada saat kegiatan tebang, muat dan angkut tebu.

Induksi Mutasi Fisik pada Paku Bintik (Microsorum punctatum) melalui Iradiasi Sinar Gamma
Authors: Rahman Qisthi Kustia , Aisyah Syarifah Iis
Published: September 2018

Pemuliaan mutasi dengan iradiasi sinar gamma merupakan salah satu cara dalam meningkatkan keragaman genetik tanaman. Tujuan penelitian ini adalah mengetahui radiosensitivitas dan nilai LD50 (Lethal dose 50) sinar gamma pada M. punctatum serta mengamati keragaan tanaman M. punctatum hasil iradiasi sinar gamma pada MV1. Nilai LD50 merupakan salah satu parameter untuk mengukur tingkat sensitivitas suatu jaringan terhadap iradiasi. Semakin rendah nilai LD50 suatu jaringan tanaman, semakin tinggi tingkat radiosensitivitasnya, sehingga semakin besar peluang terjadinya mutasi. Penelitian ini menggunakan rancangan acak lengkap (RAL) faktor tunggal (dosis iradiasi sinar gamma) dengan 3 ulangan. Iradiasi sinar gamma diberikan terhadap stek rimpang dengan satu daun dari tanaman M. punctatum secara tunggal (acute irradiation) menggunakan Gamma Cell 220 dengan dosis 0, 10, 20, 30, 40, dan 50 gray. Semua rimpang dengan satu daun hasil iradiasi ditanam di lapangan hingga 16 minggu setelah iradiasi (MSI). Hasil penelitian menunjukkan bahwa pemberian iradiasi sinar gamma pada M. punctatum menghasilkan LD50 sebesar 86,25 gray dan perlakuan iradiasi sinar gamma antar perlakuan berbeda nyata terhadap tinggi dan lebar daun, sedangkan karakter jumlah daun tidak berbeda nyata. Perlakuan iradiasi juga menyebabkan defisiensi warna hijau pada daun M. punctatum. Secara morfologi, perlakuan iradiasi sinar gamma terhadap M. punctatum belum menghasilkan mutan-mutan yang diinginkan, namun secara genetik, terdapat penggandaan jumlah kromosom dan aberasi kromosom pada perlakuan dosis iradiasi tertinggi (50 gray).

There are two types of population growth function  of the basic formulation of Schaefer’s biology model, however in this study there is a difference in form and value of “r” as one of a biology parameter.   In addition  to the difference in the method by calculating the process of a and b coefficient. The calculating process of a and b coefficient in Schaefer’s biology model was conducted through linear regression which has not yet been exact.  This is  due to  the model itself which is quadratic. Therefore to provide the solution is through quadratic process. The linear regression shows the value of fmsy and Ymsy 1.40 and 1.34 times smaller than quadratic process respectively. Based on the two graphs from the calculating process of a and b coefficient, it can be concluded that the utilization of yellowfin tuna fishery was still not optimal. According to the result based on the linear and quadratic regression, the maximum production of yellowfin tuna  can be increased to 664,037 and 877,340 kg.Keywords: Population growth function, Schaefer’s Biology Model, Utilization status, Yellowfin tunaABSTRAKDua jenis fungsi pertumbuhan populasi menjadi dasar pembentukan model biologi Schaefer, namun dalam kajian ini terdapat perbedaan dalam bentuk dan nilai r sebagai parameter biologi ditambah juga berdasarkan perbedaan metode perhitungan koefisien a dan b. Metode perhitungan koefisien a dan b model biologi Schaefer melalui regresi linear masih kurang tepat, karena model biologi Schaefer berbentuk kuadratik, sehingga penyelesaiannya harus melalui proses kuadratik. Nilai fmsy dan Ymsy dari proses regresi linear memiliki nilai 1,40 dan 1,34 kali lebih rendah dari proses kuadratik. Berdasarkan kedua kurva dari kedua metode perhitungan koefisien a dan b, maka status pemanfaatan perikanan tuna madidihang diduga masih belum optimal. Sehingga berdasarkan proses regresi linear dan kuadratik, maka produksi maksimal tuna madidihang masih dapat ditingkatkan sampai dengan 664.037 dan 877.340 kg.Kata kunci:  Fungsi pertumbuhan populasi, Model biologi Schaefer, Status pemanfaatan Tuna madidihang

Stakeholders, who are agents and actors in this matter play an important role in the management of reef fisheries in Wakatobi National Park. This study aims to identify the agents and actors in Wakatobi Regency and to identify similarities and differences of the perception between agents and actors in the management of conservation areas. The method used is  Principal Component Analysis (PCA). The result showed that there was a similar perception between agent and actor in which that the conservation gives benefit for the society in Wakatobi and the lack of regulation in Wakatobi Regency. Different perceptions between actors and agents occurred due to fishermen intention to fully utilize the resources for their welfare while the government intents to limit the fishing area in order to preserve the natural resources and the environment. Therefore, management related to the  regulation on legal-size of fish and the effectiveness of marine protected areas are needed.

La comunidad de Ixtlán de Juárez, Oaxaca, posee un potencial maderable importante debido a la productividad alta de su bosque. Una de las especies con mayor importancia es Pinus patula debido a la distribución y valor comercial alto; además, es de crecimiento rápido. Por lo tanto, es necesario determinar los límites de la densidad máxima posible que los rodales pueden sustentar para dirigir acciones encaminadas al control de la competencia y redistribución del espacio de crecimiento. En este estudio se estimó la línea de densidad máxima (límite superior del autoaclareo) con el modelo de Reineke mediante dos enfoques de estimación de los parámetros: (1) mínimos cuadrados ordinarios (MCO) y (2) regresión de frontera estocástica (RFE) con los modelos de tipo seminormal (half-normal) y normal truncado (truncated-normal). Para el ajuste del modelo se utilizaron datos de 64 parcelas permanentes de investigación silvícola de 400 m2 de rodales puros y coetáneos de P. patula. La estimación del límite superior del autoaclareo con el modelo de RFE en la forma seminormal fue eficiente y permitió conocer el índice de densidad máxima de los rodales estudiados. La línea de densidad máxima representó el insumo primordial para construir una guía de densidad; herramienta indispensable para la definición de regímenes de aclareo y optimización del espacio de crecimiento.

La cantidad de precipitación que llega a la superficie terrestre depende en gran medida de la cobertura vegetal. Está cubierta intercepta gran parte de la precipitación y la almacena temporalmente, donde es devuelta a la atmósfera por medio de la evapotranspiración. El objetivo del presente trabajo fue cuantificar y analizar las pérdidas por intercepción de lluvia bajo diferentes intensidades de raleo en un área de Matorral Espinoso Tamaulipeco (MET) en el noreste de México. En la Facultad de Ciencias Forestales dentro del municipio Linares, Nuevo León, se establecieron cuatro parcelas para la precipitación directa bajo cuatro intensidades de raleo; 75, 50, 25 y 0 %, y una parcela para la precipitación incidente. Se registraron 79 eventos de lluvia (907.6 mm) para 2016 y 2017. Los porcentajes de intercepción de lluvia fueron de 16, 29, 34 y 41 % para las intensidades de raleo de 75, 50, 25 y 0 %, respectivamente. Los análisis de regresión lineal simple señalan que la precipitación directa representa 83, 70, 65 y 58 % del total de precipitación para las intensidades de 75, 50, 25 y 0 %, respectivamente. Los coeficientes de determinación para precipitación directa e incidente fueron de r2=0.8651 y r2=0.8017 para los raleos al 25 y 0 %; esto indica que a medida que se incrementó el raleo, aumentó la precipitación directa. Las características del dosel y el follaje de las distintas especies del MET pudieron influir en el porcentaje de intercepción de lluvia.

El Matorral Espinoso Tamaulipeco está constituido por árboles y arbustos que producen gran cantidad de hojarasca esencial para el suelo y el ciclo de los nutrientes, el cual es complejo de entender. El objetivo del presente trabajo fue determinar el contenido de Ca, K, P, Mg, Cu, Fe, Mn y Zn durante el proceso de degradación de la hojarasca y comparar su dinámica en dos estaciones. La hojarasca se recolectó 15 días previos a cada estación y se dejó en campo para evaluar su descomposición (10 g), mediante la técnica de bolsa de nylon durante el invierno y la primavera. La tasa de descomposición (k, g g-1 año-1) fue de 0.002 y 0.003, respectivamente. En la estación de invierno, el Ca y P registraron una acumulación de 34.7 y 0.32 mg g-1, respectivamente; el K, liberó 7.2 y el Mg, 0.3 mg g-1; el Cu 1.0 µg g-1; el Fe incrementó 402.8 y el Mn 7.9 µg g-1; el Zn presentó una acumulación de 0.04 µg g-1. En primavera, el Ca tuvo una acumulación de 10.93 mg g-1 y el contenido de P fue 0.7 mg g-1. Al igual que en la temporada invernal, los minerales que registraron liberación fueron K (6.3 mg g-1) y Mg (0.49 mg g-1). Con respecto a Cu, Fe, Mn y Zn, se observó acumulación a razón de 2.7, 446.3, 6.3 y 16.1 µg g-1, respectivamente.

Published: September 2018

Thesis is a final project that is quite scary for most students in Indonesia. In the process of compilation, students often do things that are non-productive, such as procrastination and avoid supervisor. Sometimes, excessive academic anxiety of this thesis can lead students to do things beyond common sense, namely suicide. If examined in more depth based on counseling approach Cognitive Behavior Therapy (CBT), academic anxiety to the thesis experienced by students is a cognitive distortion caused by maladaptive core beliefs. Therefore, students who experience it need to get help so that their core beliefs can be more adaptive again. Based on the latest research results, integration of CBT counseling with more modern techniques of music therapy has proved effective in reducing academic anxiety and improving self-efficacy of thesis students. Thus, through this conceptual study, it is hoped that counselors in Indonesia will be able to understand, practice and conduct further research on CBT counseling interventions integrated with music therapy.

In behaving towards what happens in him, man will be oriented in two directions, there are individuals who believe that what happens to him is the result of his own efforts, on the contrary there are individuals who believe that the events that occur are influences from outside the self. This belief is called the locus of control. Each individual has a difference in the locus of control. This difference is influenced by several factors, one of which is ethnicity. This study aims to describe the locus of control of individuals belonging to the ethnic Kerinci, Java and Minang, and reveal differences in the locus of control of the three ethnic groups. This research uses quantitative approach with descriptive and comparative method. The sampling technique used is simple random side with total number 230 students. The instrument used is Internal Rotters inventory -External Locus of Control (I-E Scale). Data were analyzed by using descriptive statistics and one way anova. The findings of this study include: 1) locus of control of ethnic Javanese students tend to external, while ethnic Kerinci and Minang reside in internal. However, the third locus of control score is not far behind the median locus of control; and 2) there are differences in locus of control of students who have ethnic Kerinci, Java and Minang. The researcher suggested to the Counselor Teacher / Counselor to always pay attention deeply and sensitively to the condition of the foster students, including the locus of control aspect. These efforts can be made by applying several counseling services with certain approaches that are theoretically proven effective in forming an internal locus of control. Parents should also provide understanding to the children about all the events that happen to him and how to react. Subsequently to other researchers, the results of this research need to be addressed and followed up by adding samples and considering some other characteristics, such as gender, age, social demography, economic and family status, religion, and others.

Historical, in addition to having auxiliary science in his knowledge, history also establish relationships with other sciences, especially fellow social sciences. In this connection what happens is a relationship of mutual need, herein lies the difference with the concept of science Auxiliary history, where a more dominant history in need of help to uncover a problem, more precisely we can call it with a combination of two social sciences. The development of post-World War II History shows a strong tendency to use the social sciences approach in historical studies. One of the basic ideas is that: the descriptive-narrative history is no longer satisfactory to explain complex problems or symptoms in the event of History. Psychology is very related to mental and psychological human. Humans who become the object of historical study is not just explained about the actions taken and what is caused by the action? why someone does that action? These questions pertain to the psychological condition in question. Conditions that can be caused by stimuli from the outside or the environment, can also from within himself. The use of social phsychology in history, gave birth to the focus of the study of the history of mentality.

Concentration and temperature dependences of parameters of the EPR spectra of Gd3+centers introduced into the Pb1-xAgxS and Pb1-xCuxS thermoelectric semiconductor crystals (0 ≤ x ≤ 0,011) were investigated by means of EPR method. The crystals under investigation were grown from the melt containing lead sulfide, silver (or copper) sulfide, gadolinium and sulfur (the latter was used to provide stoichiometry). The investigations were performed in the 9320÷9340 MHz frequency range at temperatures of 4.2, 77, and 300 K. It was established that in the samples studied the silver and copper impurities did not create significant distortions in the structure of the base PbS crystal, but significantly affected the concentration of free carriers. Analysis of the obtained data on the concentration and temperature dependences of the spin-Hamiltonian parameters of the Gd3+probe centers leads to the conclusion that silver and copper in the PbS crystal are acceptor like impurities, and also to determine their solubility and describe the distortions induced by them in the structure of the base crystal.
