Published: January 2020

The development of reformation era has provided diverse discourses of masculinity that develop in Indonesia society. This paper aims to examine the changing perceptions of masculinity in Indonesia supplementary beverage advertising. Based on the theory of semiotics expressed by Roland Barthes, this paper examines the changing perceptions of masculinity reflected on five ads of Extra Joss for “Qurbani” (the day of sacrifice) edition. This paper will analyze the symbols of masculinity through the use of linguistic and visual elements in the advertisement.The result showed that there had been changes in the perceptions of masculinity in Extra Joss ads for “Qurbani” or the day of sacrifice edition. Four advertisements made before 2017 showed the image of masculinity characterized by the glorification of body strength, aggressiveness, and fearless attitude of men. This value of masculinity is also marked through the use of aggressive linguistic markers such as the use of the word laki, fearless, penjinak, etc. However, one advertisement that was created in 2017 showed a softer image of masculinity. It was marked by warmth and togetherness behaviors of men generated by the male model in the ad. This was reinforced by the emergence of female characters in the ad. The analysis also showed that these masculinity changes were influenced by K-Pop globalization which generated a softer masculinity than previous advertisements. In addition, the analysis also showed changes in the meaning of “Qurbani” (sacrifice) in the ads. Previously, it was marked as something that was achieved and struggled. However, nowadays “Qurbani” or sacrifice is seen as a joyful activity.

Published: January 2020

The Malay and Minangkabau people are those who like to speech and act on literature. This can be seen through the existence of several genres of literary works from those ethnic, ranging from the form of saga, tale, and legend. Among them are Hang Tuah and Cindua Mato saga. Hang Tuah saga grew and developed in Malay society, while Cindua Mato saga grew and developed in Minangkabau society. Both sagasare interesting to be studied as an analytical study. First, Hang Tuah and Cindua Mato saga is a great literary work owned by both ethnic groups. As a masterpiece, they both have an appeal to be analyzed in many ways. Secondly, Hang Tuah and Cindua Mato figures by both ethnic communities have become a big myth. Hang Tuah became myth by the Malay community as a brave and loyal figure to the king. So did with the figure of Cindua Mato who became myth by Minangkabau society as a brave and loyal figure to the king. As with other literary works, Hang Tuah and Cindua Mato saga contains the aesthetic, moral, and cultural elements of their owners. It is as stated by Taum that oral literature has an aesthetic effect and moral context as well as a particular society culture. This research analyzed and examined the cultural similarities and differences (characters) in Hang Tuah and Cindua Mato saga. This study is expected to produce the same perception of both sagas. Likewise, the possibility of a kinship element exists between ethnic Malay and Minangkabau.

Hydrolytic Expansion Induces Corrosion Propagation for Increased Fe Biodegradation
Authors: Shuai Cijun , Li Sheng , Peng Shuping , Yang Youwen , Gao Chengde
Published: January 2020

Fe is regarded as a promising bone implant material due to inherent degradability and high mechanical strength, but its degradation rate is too slow to match the healing rate of bone. In this work, hydrolytic expansion was cleverly exploited to accelerate Fe degradation. Concretely, hydrolyzable Mg2 Si was incorporated into Fe matrix through selective laser melting and readily hydrolyzed in a physiological environment, thereby exposing more surface area of Fe matrix to the solution. Moreover, the gaseous hydrolytic products of Mg2 Si acted as an expanding agent and cracked the dense degradation product layers of Fe matrix, which offered rapid access for solution invasion and corrosion propagation toward the interior of Fe matrix. This resulted in the breakdown of protective degradation product layers and even the direct peeling off of Fe matrix. Consequently, the degradation rate for Fe/Mg2 Si composites (0.33 mm/y) was significantly improved in comparison with that of Fe (0.12 mm/y). Meanwhile, Fe/Mg2 Si composites were found to enable the growth and proliferation of MG-63 cells, showing good cytocompatibility. This study indicated that hydrolytic expansion may be an effective strategy to accelerate the degradation of Fe-based implants.

Published: January 2020

Lettuce is the most-produced leafy vegetable in Brazil; however, to achieve satisfactory production in the different regions, it is necessary to choose the correct cultivar. The aim of this work was to evaluate the productive and physiological performance of lettuce cultivars in a hydroponic system located in Caucaia, in the state of Ceará. A completely randomised design was used, with four cultivars (Isabela, Vanda, Elba and Summer Crisp) and four replications. The following were evaluated: plant height and diameter (PH and PD), total fresh and dry weight (TFW and TDW), commercial fresh weight (CFW), internal CO2 concentration (Ci), stomatal conductance (gs), photosynthesis (A), ratio between internal and external CO2 concentration (Ci/Ca), and transpiration (E). Differences were seen between cultivars in the production and physiological characteristics, except for Ci and Ci/Ca. The ‘Elba’ and ‘Summer Crisp’ cultivars were the first to show signs of bolting (32 and 36 days) and greater height, 38.7 and 31.8 cm respectively. The ‘Isabela’ and ‘Vanda’ cultivars obtained the greatest values for CFW (43.5 and 41.13 g) and TFW (49.38 and 46.46 g). In relation to physiological performance, the ‘Isabela’ and ‘Summer Crisp’ cultivars presented the most photosynthesis. The ‘Isabela’ cultivar had the best productive and physiological performance, in addition to being the only cultivar that presented no signs of bolting, and is therefore strongly suggested for hydroponic production under the conditions of this study.

Purification and partial characterization of glutamine synthetase isoforms from Triticale seedlings.
Authors: Bielawski W
Published: January 2020

Two isoforms of glutamine synthetase (EC 6.3.1.2), cytoplasmic (GS1) and chloroplastic (GS2) were isolated from shoots of 14-day-old Triticale seedlings, and purified 260-fold and 248-fold, respectively. Specific activities of the two preparations were 35.1 and 33.5 mumol x min-1 per mg of protein, respectively. Both crude extracts and homogeneous GS1 and GS2 preparations required divalent metal ions (Mg2+, Mn2+, Co2+) for their activities. Mg2+ was the most effective activator, the highest activity of GS1 being reached at 5 mM, and that of GS2 at 20 mM MgCl2. The optimum pH for the two isoforms showed large differences, dependent also on the kind of divalent ion. Molecular masses of GS1 and GS2 were 305000 Da and 385200 Da, respectively. It seems that native protein of GS1 is built from eight identical subunits of Mm 38000 Da and that of GS2 of the same number of subunits but of Mm of about 48000 Da. Proteins of GS isoforms differed significantly in their amino-acid composition.

Published: January 2020

The elongation factor 2 (eEF-2) protein kinase was isolated from rat liver cells, purified and partly characterized. It was found that the enzyme exists in an inactive form in the homogenate of rat liver. The active fraction of kinase eEF-2 was obtained after removal of the inhibitory substance by hydroxyapatite column chromatography. The purified enzyme is an electrophoretically homogeneous protein with relative molecular mass of approximately 90,000 and isoelectric point, pI = 5.9. The enzyme specifically phosphorylates the elongation factor eEF-2 in the presence of calmodulin and Ca2+.
How many 5S rRNA genes and pseudogenes are there in Aspergillus nidulans?
Authors: Pelczar P , Fiett J , Bartnik E
Published: January 2020

We have estimated the number of 5S rRNA genes in Aspergillus nidulans using two-dimensional agarose gel electrophoresis and hybridization to appropriate probes, representing the 5'-halves, the 3'-halves of the 5S rRNA sequence and a sequence found at the 3'-end of all known A. nidulans pseudogenes (block C). We have found 23 5S rRNA genes, 15 pseudogenes consisting of the 5'-half of the 5S rRNA sequence (of which 3 are flanked by block C) and 12 copies of block C which do not seem to be in the vicinity of 5S rRNA sequences. This number of genes is much lower than our earlier estimates, and makes our previously analyzed sample of 9 sequenced genes and 3 pseudogenes much more representative.

Thermostable farnesyl diphosphate synthase of Bacillus stearothermophilus: crystallization and site-directed mutagenesis.
Authors: Koyama T , Obata S , Osabe M , Saito K , Takeshita A , Nishino T , Ogura K
Published: January 2020

The gene for thermostable farnesyl diphosphate synthase from Bacillus stearothermophilus was cloned, sequenced, and overexpressed in Escherichia coli. The synthase was purified to homogeneity and crystallized. The enzyme carried only two cysteine residues in contrast to its counterparts from other sources, which have four to six cysteine residues. Either or both of the cysteine residues can be replaced with serine without causing a loss of the catalytic activity. The conserved arginine residue that occupies the third position from the C-terminus was also replaced with valine without significant loss of activity, but the valine mutant showed a weakened affinity for isopentenyl diphosphate.
Modulation of mannosylphosphodolichol synthase and dolichol kinase activity in Trichoderma, related to protein secretion.
Authors: Kruszewska J , Kubicek C P , Palamarczyk G
Published: January 2020

It has been postulated that exoprotein secretion in Trichoderma is related to their O-glycosylation. In the present paper the involvement of phosphodolichol in this process is described and the key role of mannosylphosphodolichol (MPD) synthase in protein O-mannosylation is discussed. The effect of water soluble phospholipid precursors such as choline and Tween 80, known also to increase secretion of cellulases when added to the medium, on MPD-synthase activity is presented. This effect is positive in the Trichoderma reesei QM 9414 (a low producing strain) but has no influence on the enzyme activity from the RUT C-30 strain selected to overproduce secretion of exoproteins and known to contain an increased cellular amount of endoplasmic reticulum. The positive effect of addition of choline and Tween to the medium on the level of dolichol kinase activity is also demonstrated. The influence of cultivation temperature on the activity of the various enzymes involved in dolichol-dependent protein glycosylation i.e. MPD-synthase, dolichyl kinase and MPD/Protein mannosyl transferase was tested. For all enzymes cultivation at 35 degrees C led to the elevated activity, which was most striking for dolichol kinase, whereas for MPD-synthase and MPD/Protein mannosyl transferase the difference was only apparent in the assay when endogenous phosphodolichol was used as a substrate. Furthermore, lipid extract from the membranes cultivated at elevated temperature, when added to the enzyme obtained from Trichoderma grown at 25 degrees C, enhanced the dolichol kinase activity measured in the absence of exogenous dolichol.(ABSTRACT TRUNCATED AT 250 WORDS)
Dolichols and proliferating systems.
Authors: Trentalance A
Published: January 2020

The results obtained on dolichol metabolism, in two in vivo model systems, the developing rat liver and the regenerating rat liver, which provide different timing and interplay of proliferation and differentiation processes, have been reported. The regenerating liver presents a marked increase of both synthesis and content of dolichol, a decreased cholesterol/dolichol ratio, unchanged synthesis and content of dolichyl phosphate, or dolichol-kinase and dolichyl phosphate-phosphatase activities; no significantly modified distribution of dolichol homologs, with respect to the control. Total content of dolichols is growing during perinatal development. At fetal stages only short chain dolichols are detectable, while the content of dolichyl phosphate is very low and the activity of dolichyl phosphate-phosphatase is high. The study of the role of liver in dolichol supply to the body in the partially hepatectomized rat shows an increased content of dolichol in the blood; blood dolichol is essentially provided by the release from liver and dolichol traffic in the blood is mediated by multiple carriers.
Activity of platelet alpha-6-fucosyltransferase is inversely related to blood platelet concentration.
Authors: Kościelak J , Antoniewicz-Papis J , Zdebska E , Maj S , Leszko B
Published: January 2020

The activity of serum alpha-6-fucosyltransferase, a platelet derived enzyme, determined in sera of 22 normal individuals and 86 patients with various disorders was positively correlated with platelet counts. When the enzyme activity in 1 microliters serum was calculated per 1000 of platelets in blood (coefficient F/P) an inverse correlation became evident in that F/P was proportionally the higher the lower was platelet count in blood. The F/P values were in a good agreement with the results of direct assays of enzyme activities in isolated platelets. Neither granulocytes, lymphocytes nor red cells significantly contributed to serum enzyme activity though granulocytes enhanced the thrombin-induced enzyme release from platelets. In platelets separated by centrifugation in density gradients the enzyme was shown to be present in platelets of intermediate and high density but missing from the light ones. It is suggested that alpha-6-fucosyltransferase of platelets may be a marker of the ploidy level of megakaryocytes.
Aspects of self- and cross-association hydrophobicity in a single chain binary mixture. A computer study.
Authors: Movileanu L , Popescu D
Published: January 2020

The differential scanning calorimetry (DSC) traces for binary mixtures of single chain amphiphiles present more than one transition temperature, while the traces for pure single chain amphiphiles have a single (or at most two) transition temperature(s). These secondary transition temperatures can appear owing to the selective association processes between the components of the lipid mixtures. This paper presents an attempt to examine theoretically the association of single chain amphiphiles between (a) two identical molecules (self-association) and (b) two different molecules (cross-association). Association probabilities, the mean association probabilities and the overall ratio of efficiency, were evaluated for 36 binary mixtures of single chain amphiphiles. A test system for evaluation of differential effects of the hydrophobic chain length on the mean association probabilities was considered. Self-association of longer hydrophobic chains and cross-association phenomena show a high probability compared with the self-association of shorter hydrophobic chains. We found that "the efficacious length of association" in a binary mixture of single chain amphiphiles is 8 methylene groups.

Authors: Zaborska W
Published: January 2020

The influence of four inhibitors: boric acid, thioglycolic acid, sodium fluoride and acetohydroxamic acid on the activity of urease, both in the native form and immobilized covalently on glutaraldehyde-pretreated chitosan membrane, was studied. Urea hydrolysis was carried out in phosphate buffer, pH 7, at 25 degrees C at urea concentration of 50 mM. The immobilized urease was more resistant than the native one to the action of all the investigated inhibitors, except boric acid. This property of the enzyme offers a possibility of its practical application.

As épocas utilizadas nos manejos de plantas de cobertura podem prejudicar o desempenho das semeadoras e a produtividade de culturas subsequentes, uma vez que propiciam diferentes condições quali e quantitativas de palhada. Nesse contexto, o objetivo do trabalho foi verificar a influência das épocas de dessecação da aveia preta e mecanismos sulcadores na plantabilidade, desenvolvimento e produtividade da cultura do milho. O experimento foi conduzido no delineamento de blocos ao acaso, em esquema fatorial 4 x 2, com 4 repetições. Os tratamentos foram constituídos de quatro épocas de dessecação da aveia, sendo elas 0, 15, 30 e 45 dias antes da semeadura do milho e dois mecanismos sulcadores (haste e disco duplo). A antecipação da dessecação da aveia preta melhora as condições de plantabilidade, mas não proporciona aumento na produtividade de grãos. Apesar de o sulcador tipo haste apresentar maior estande de plantas, ele mobiliza muito solo e não apresenta ganho na produtividade em relação ao disco.

O delineamento utilizado foi o de blocos ao acaso, com oito tratamentos e cinco repetições, em fatorial 3x2+2. Os fatores foram três misturas de herbicidas com atrazine (ATR) + nicosulfuron (NIC) (1000 + 45 g i.a. ha-1), ATR + mesotrione (MES) (1000 + 144 g i.a. ha-1); ATR + tembotrione (TEM) (1000 + 100,8 g i.a. ha-1), duas condições de associação ou não ao fertilizante foliar Fertiactyl Pós® (FEP) (400 mL ha-1), com testemunhas capinadas e sem capina. A associação de FEP com os herbicidas ATR + NIC, ATR + MES e ATR + TEM não interferiu na deposição da pulverização em milho e erva quente (Spermacoce latifolia), assim como na eficiência de controle de plantas daninhas e produtividade de grãos. O FEP associado as misturas em tanque dos herbicidas apenas apresentou resultado promissor na redução da fitointoxicação visual e manutenção dos níveis de clorofila iniciais na cultura do milho.
Indigenous Income Disparity and Resguardo Land in Colombia
Authors: Sanchez Garcia Rosa Evelia
Published: January 2020

This article examines the association between the resguardo, a colonial land access system similar to the North American reserve and reservation systems, and income inequality among Indigenous people in Colombia. I regressed the variable income unmet basic needs gap (IUBNgap) between Indigenous people and non-minority people in Colombia on a set of regressors that included the mean of resguardo land size per family. I find that more resguardo land per family is associated with a larger IUBNgap, which is likely due to the fact that resguardos tend to be larger where lands are isolated and where most of the land suitable for economic production is owned by non-Indigenous landowners.

was characterized by FT-IR, SEM-EDX and PZC analyses. The
adsorption process
of Pb2+
ions onto Ch-D as initial lead concentration, solution
pH, temperature,
contact time and
recovery was
investigated. From
the adsorption process results, it has been observed that the highest
removal efficiency is approximately 95% at a contact time of 4-hour,
initial Pb2+
concentration
of 500 mg L-1
and agitation speed of 150 rpm at natural pH 4.0.
The maximum Pb2+
adsorption
capacity from the Langmuir model was found
as 0.154
mol kg-1
at 25 oC.
Besides,
adsorption kinetics was also explained with pseudo-first-order
models. Adsorption
thermodynamics have shown that Pb2+
adsorption onto Ch-D is possible, spontaneous and exothermic. Ch-D
composite can become an alternative adsorbent for the treatment of
lead ions in the wastewater.

Authors: ÖZGEN Ahmet Ozan , EYÜPOĞLU Ozan Emre
Published: January 2020

Antibiotic
resistance in bacteria has become a worrying phenomenon in today's world. K. pneumoniae is a member of the Enterobacteriaceae family, which causes
nosocomial infections as an opportunistic pathogen but inherently harboured as
a part of natural human microbiota. Carbapenem resistance of K. pneumoniae was a rare occurrence up
to ten years ago, but in recent years many types of carbapenemase producing K. pneumoniae have become common. The
aim of this retrospective study; analyzing susceptibility to various
antibiotics, commonly used in treatment, against K. pneumoniae strains isolated from various infection sites.
Antibiotic susceptibility tests were performed by using the VITEK 2 Compact ®
automated system. In this study, 502 K.
pneumoniae strains  isolated from
patients that treated at various services of a university hospital with 515 bed
capacity were examined. When compared to the data available with studies of
recent years in Turkey, especially in intensive care and inpatient services,
resistance of K. pneumoniae strains
to antibiotics, against most carbapenems, are rapidly increasing in the degree
of high concern. Therefore, in all hospitals, antibiotic management policies
should be implemented with a multidisciplinary approach.

Creating transnational, intercultural arts’ interactions: African diasporic dialogues
Authors: Pierre Alix
Published: January 2020

Painted with broad as well as, highly nuanced brush strokes, this is a comprehensive essay. Initially, it traces and later weaves within the larger discussion, the influences of Marcus Garvey’s philosophy and his lasting contributions to Africans in the diaspora. As importantly, the essay highlights the exceptional works of two Jamaican-born artists who reside in the USA. Thirdly, the essay explores some of the Miami-based Diaspora Vibe Cultural Arts Incubator’s, (DVCAI’s) intercultural exchanges, in which artists challenge dominant Western perspectives. Fourthly, the essay summarizes key aspects of DVCAI’s international cultural exchange in Jamaica. The recent, transcultural arts’ exchanges exemplify, reciprocal dialogues between the DVCAI’s representatives and the Jamaican arts community, specifically, with artists who adopt a Freirean pedagogy and focus on significant social justice issues in a postcolonial country.

A Note on Distributive Triples
Authors: Łazarz Marcin
Published: January 2020

Even if a lattice L is not distributive, it is still possible that for particular elements x, y, z ∈ L it holds (x∨y) ∧z = (x∧z) ∨ (y ∧z). If this is the case, we say that the triple (x, y, z) is distributive. In this note we provide some sufficient conditions for the distributivity of a given triple.

Adanya inovasi-inovasi baru dalam pendidikan, sebenarnya bertujuan untuk memberikan output yang semakin baik bagi. Salah satu output yang dimaksud adalah moral. Faktanya, hal ini belum sepenuhnya tercapai. Salah satu hal yang mampu mendorong pencapaian output  pendidikan yang baik adalah ekstrakurikuler kepramukaan. Kajian ini memfokuskan terhadap ekstrakurikuler kepramukaan dengan dua alasan, yaitu adanya Undang-undang nomor 12 tahun 2010 tentang Gerakan Pramuka; dan Pramuka dinilai mampu mengajarkan banyak nilai, mulai dari kepemimpinan, kebersamaan, sosial, kecintaan alam, hingga kemandirian. Begitu banyak hal yang mampu diambil manfaatnya dari ekstrakurikuler tersebut. Dengan demikian kajian ini mengulas tentang pengaruh latihan kepramukaan terhadap perkembangan moral peserta didik. Tidak hanya pengaruhnya terhadap output pendidikan, namun  tahap perkembangan peserta didik juga tidak luput dari ulasan yang berkaitan dengan ekstrakurikuler ini. Pada akhirnya, latihan kepramukaan memiliki kecenderungan mampu mengembangkan moral peserta didik  yang diketahui berdasarkan permainan yang terdapat di dalamnya. Dengan sebuah permainan yang memiliki aturan yang tegas, maka pesertanya pun akan mematuhinya. Permainan yang dimaksud tentunya yang mampu meningkatkan moral. Moral yang dimaksud berupa kesantunan peserta didik dalam bersikap dan bertingkah laku.

Authors: Munjiyat Munjiyat
Published: January 2020

Sebagai bahasa asing, pembelajaran bahasa Arab di Indonesia seakan tidak pernah surut dari problematika klasik, mulai dari unsur linguistik sampai non linguistik.  Al-mahÄrÄt al-arbaâ€™ yang menjadi fokus pembelajaran bahasa, menjadi tolak ukur keberhasilan sebuah pembelajaran bahasa. Masing-masih mahÄrah (skill) tersebut mempunyai tantangan yang berbeda-beda. Salah satu mahÄrah yang sulit dikuasai adalah maharoh al-QirÄâ€™ah (reading skills), selain faktor huruf yang berbeda, gramatikal, morfologi, dan kosakata, tidak adanya harokat pada teks juga menjadi tantangan utama bagi para pendidik dan pembelajar bahasa Arab. Maka peneliti tertarik untuk membuat format baru, dengan mendesain materi yang sudah ada (buku) menjadi materi yang berbasis komputer (CD Pembelajaran), dengan harapan pembelajaran semakin menarik dan tujuan pembelajaran bisa tercapai. Penelitian tersebut dilaksanakan di SMP Islam yang notabene siswanya tidak pernah belajar bahasa Arab, tetapi ketrampilan IT-nya sudah baik.  Jenis penelitian yang digunakan adalah penelitian kuantitatif deskriptif, sedangkan instrumen pengumpulan data yang digunakan adalah 1. Tes, 2. Interview, dan 3. Angket. Dari penelitian tersebut dapt disimpulkan bahwa desain materi ajar berbasis komputer berdampak signifikan terhadap perkembangan kemampuan membaca siswa, hal tersebut ditunjukkan dengan perubahan rata-rata nilai pretest yang mencapai 57,87 meningkat menjadi 77,40 pada rata-rata nilai posttestnya. Hasil tersebut diperkuat dengan t test yang dilakukan peneliti serta hasil analisa angket dan interview
Pendidikan Islam Indonesia dan Tantangan Globalisasi: Perspektif Sosio-Historis
Authors: Gaus Djulaiha
Published: January 2020

Tantangan nasional dan global yang dihadapi oleh pendidikan Islam semakin kompleks, khususnya di Indonesia di era global ini, dihadapkan pada problematika filosofis-sosial yang tidak kunjung usai. Ada dua masalah yang dihadapi oleh pendidikan Islam pada tantangan Globalisasi. 1). Sebagai peluang, (globalisasi) satu sisi akan memudahkan pendidikan Islam untuk mengakses berbagai informasi dengan mudah. Juga memudahkan pendidikan Islam untuk menyebarluaskan (diseminasi) produk-produk keilmuan yang memberikan manfaat seluas-luasnya bagi masyarakat. 2). Sebagai tantangan, ternyata globalisasi tidak hanya mempengaruhi tatanan kehidupan pada tataran makro, tetapi juga mengubah tata kehidupan pada tataran mikro, misalnya terhadap ikatan kehidupan sosial masyarakat. Yaitu, Fenomena disintegrasi sosial, hilangnya nilai-nilai tradisi, lunturnya adat-istiadat, sopan santun, dan penyimpangan sosial lainya Dalam tulisan ini, berkesimpulan bahwa, lembaga-lembaga pendidikan Islam secara keseluruhan tetap menjalankan perannya dalam tiga hal pokok:  transmisi ilmu-ilmu dan pengetahuan Islam (transmission of Islamic knowlwdge); kedua, pemeliharaan tradisi Islam (maintenance of Islamic tradition); ketiga, kaderisasi calon-calon ulama. Peserta didik tidak hanya menggetahui ilmu-ilmu agama, atau sebaliknya tidak hanya mengetahui pengetahuan umum, dengan demikian, dapat melakukan mobilisasi pendidikan. Disamping itu, para anak didik memiliki keterampilan, keahlian atau life skills khususnya dalam bidang sains dan teknologi yang menjadi karakter dan ciri globalisasi, yang pada gilirannya membuat mereka  memiliki dasar-dasar dalam lapangan kerja sebagaimana dituntut di alam globalisasi.
